-## 4. 核心功能
+- 接口不加 `I` 前缀
+- 方法: 动词开头 `save()`/`list()`/`detail()`/`remove()`；布尔用 `is`/`has` 前缀
+- 常量 UPPER_SNAKE_CASE；字段常量用 `@FieldNameConstants` 生成 `{Class}.Fields.{field}`
+- 泛型: 简单用 `T`/`E`，领域用 `ENTITY`/`SAVE_ITEM`/`LIST_ITEM`/`DETAIL_ITEM`
 
-### 4.1 基础CRUD操作
+### 代码风格
 
-#### 4.1.1 创建(Create)
-支持通过 POST 请求创建实体对象。通过 save 接口实现，接收 SAVE_ITEM 类型的参数，通过 Mapper 转换为实体对象后保存。
+- 2 空格缩进，K&R 大括号，不用 Tab
+- Import 排序: `java.*` → `jakarta.*` → 第三方 → `com.lanyuanxiaoyao.*`，不用通配符
+- 积极使用 Java 17 特性: `record`(DTO) / `var` / `instanceof` 模式匹配 / Text Blocks / `String.formatted()`
+- JavaDoc 用中文，含 `@param`/`@return`/`@see`，可用 `<p>`/`<h3>`/`<ul>`/`<pre>`
+- 不写 `//` 行内注释，除非必要
 
-#### 4.1.2 查询(Retrieve)
-支持多种查询方式：
-- 列表查询：获取所有实体对象
-- 条件查询：根据指定条件查询实体对象
-- 详情查询：根据 ID 获取单个实体对象
+### 注解
 
-#### 4.1.3 更新(Update)
-支持通过 POST 请求更新实体对象。通过 save 接口实现，当传入包含 ID 的对象时执行更新操作。
+用:
 
-#### 4.1.4 删除(Delete)
-支持通过 GET 请求删除实体对象。通过 remove 接口实现，根据 ID 删除指定实体。
+- 实体: `@Getter` `@Setter` `@ToString` `@FieldNameConstants`，子类加 `@ToString(callSuper = true)`
+- 日志: `@Slf4j`
+- 注入: `@RequiredArgsConstructor(access = AccessLevel.PROTECTED)`（构造器注入）
+- 事务: 写 `@Transactional(rollbackFor = Throwable.class)`，读 `@Transactional(readOnly = true)`
+- 实体基类: `@MappedSuperclass` `@EntityListeners(AuditingEntityListener.class)`

+- 不用 Swagger/OpenAPI 注解
+- 不用 `@Autowired` 字段注入
+- 不写代码注释（`//`），除非必要
 
-#### 4.2.2 条件查询
-支持基于多种条件的复杂查询，通过 list 接口实现，支持以下查询条件：
-- nullEqual: 字段值为null的条件
-- notNullEqual: 字段值不为null的条件
-- empty: 字段值为空的条件
-- notEmpty: 字段值不为空的条件
-- equal: 字段值相等的条件
-- notEqual: 字段值不相等的条件
-- like: 字段值模糊匹配的条件

-#### 4.2.4 排序查询
-支持排序查询功能，通过 sort 配置实现排序参数设置。
+### 依赖管理
 
-### 4.3 数据实体设计
+版本集中在根 POM `<properties>` + `<dependencyManagement>`，子模块不声明版本。
+全局继承: `lombok` / `jspecify:1.0.0`
+核心: `spring-boot-starter-data-jpa` / `fenix-spring-boot-starter:4.0.0` / `querydsl-jpa:7.1` / `mapstruct:1.6.3`
+database 模块注解处理器: lombok → hibernate-jpamodelgen → querydsl-apt(jpa) → jakarta.persistence-api → mapstruct-processor

-        </plugin>
-    </plugins>
-</build>
-```
-
-### 7.4 创建业务模块
-
-创建业务模块的步骤如下：
-
-#### 7.4.1 创建实体类
-
-创建实体类并继承 [SimpleEntity](src/main/java/com/lanyuanxiaoyao/service/template/entity/SimpleEntity.java)：
-
-```java
-@Entity
-@Table(name = "employee")
-public class Employee extends SimpleEntity {
-    private String name;
-    private Integer age;
-    // 其他字段和方法
-}
-```
-
-#### 7.4.2 创建仓储接口
-
-创建仓储接口并继承 [SimpleRepository](src/main/java/com/lanyuanxiaoyao/service/template/repository/SimpleRepository.java)：
-
-```java
-@Repository
-public interface EmployeeRepository extends SimpleRepository<Employee> {
-    // 自定义查询方法
-}
-```
-
-#### 7.4.3 创建服务类
-
-创建服务类并继承 [SimpleServiceSupport](src/main/java/com/lanyuanxiaoyao/service/template/service/SimpleServiceSupport.java)：
-
-```java
-@Service
-public class EmployeeService extends SimpleServiceSupport<Employee> {
-    public EmployeeService(EmployeeRepository repository) {
-        super(repository);
-    }
-    // 自定义业务方法
-}
-```
-
-#### 7.4.4 创建控制器类
-
-创建控制器类并继承 [SimpleControllerSupport](src/main/java/com/lanyuanxiaoyao/service/template/controller/SimpleControllerSupport.java)：
-
-```java
-@RestController
-@RequestMapping("employee")
-public class EmployeeController extends SimpleControllerSupport<Employee, EmployeeSaveItem, EmployeeListItem, EmployeeDetailItem> {
-    public EmployeeController(EmployeeService service) {
-        super(service);
-    }
-    
-    @Override
-    protected Function<EmployeeSaveItem, Employee> saveItemMapper() {
-        // 实现保存项转换逻辑
-    }
-    
-    @Override
-    protected Function<Employee, EmployeeListItem> listItemMapper() {
-        // 实现列表项转换逻辑
-    }
-    
-    @Override
-    protected Function<Employee, EmployeeDetailItem> detailItemMapper() {
-        // 实现详情项转换逻辑
-    }
-}
-```
-
-#### 7.4.5 创建数据传输对象
-
-创建用于数据传输的对象：
-
-```java
-// 保存项
-public class EmployeeSaveItem {
-    private Long id;
-    private String name;
-    private Integer age;
-    // getter和setter方法
-}
-
-// 列表项
-public class EmployeeListItem {
-    private Long id;
-    private String name;
-    private Integer age;
-    // getter和setter方法
-}
-
-// 详情项
-public class EmployeeDetailItem {
-    private Long id;
-    private String name;
-    private Integer age;
-    private LocalDateTime createdTime;
-    private LocalDateTime modifiedTime;
-    // getter和setter方法
-}
-```
-
-### 7.5 配置启用 JPA 审计
-
-在您的主应用类上添加 [@EnableJpaAuditing](https://docs.spring.io/spring-data/jpa/docs/current/api/org/springframework/data/jpa/repository/config/EnableJpaAuditing.html) 注解以启用 JPA 审计功能：
-
-```java
-@SpringBootApplication
-@EnableJpaAuditing
-public class YourApplication {
-    public static void main(String[] args) {
-        SpringApplication.run(YourApplication.class, args);
-    }
-}
-```
-
-### 7.6 配置 Fenix
-
-在您的 application.yml 或 application.properties 文件中添加 Fenix 配置：
-
-```yaml
-fenix:
-  # 是否开启 Fenix
-  enabled: true
-  # SQL 执行后的输出格式，console: 控制台彩色输出; html: 彩色 HTML 输出; text: 纯文本输出
-  output-format: console
-```
-
-### 7.7 测试集成效果
-
-完成以上步骤后，您可以运行您的应用程序并测试以下功能：
-
-1. 创建实体：POST /employee/save
-2. 查询列表：GET /employee/list 或 POST /employee/list（带条件）
-3. 查询详情：GET /employee/detail/{id}
-4. 删除实体：GET /employee/remove/{id}
-
-通过以上步骤，您就可以成功在现有项目中集成 Spring Boot Service Template 的能力，快速实现 CRUD 功能。

+## 核心设计
+
+### 实体继承
+
+```
+IdOnlyEntity (id: Long, @SnowflakeId)
+    ↑
+SimpleEntity (+ createdTime, modifiedTime)
+    ↑
+业务实体 (@Entity)
+```
+
+**实现要点**：
+- `@MappedSuperclass` 标记基类
+- `@SnowflakeId` 触发 `SnowflakeIdGenerator` 生成 ID
+- `@CreatedDate/@LastModifiedDate` + `AuditingEntityListener` 自动填充时间
+
+### Repository
+
+```java
+@NoRepositoryBean
+public interface SimpleRepository<E> extends
+    FenixJpaRepository<E, Long>,                    // CRUD + Fenix
+    FenixJpaSpecificationExecutor<E>,               // Specification
+    ListQueryByExampleExecutor<E>,                  // Example
+    ListQuerydslPredicateExecutor<E> {}             // QueryDSL
+```
+
+**核心能力**：
+- `saveOrUpdateByNotNullProperties()` - 部分字段更新
+- Specification - 动态条件查询
+- QueryDSL - 类型安全查询
+
+### Service 接口组合
+
+```java
+SaveService<ENTITY>      // save(entity), save(entities)
+QueryService<ENTITY>     // detail(id), list(), list(query), count()
+RemoveService<ENTITY>    // remove(id), remove(ids)
+
+SimpleService<ENTITY> extends SaveService, QueryService, RemoveService
+```
+
+**SimpleServiceSupport 实现**：
+- 保存：Fenix `saveOrUpdateByNotNullProperties()`
+- 查询：JPA Criteria + Specification
+- 删除：`deleteBatchByIds()`
+- 扩展点：重写 `commonPredicates()` 添加全局过滤条件
+
+### Controller 接口组合
+
+```java
+SaveController<SAVE_ITEM>              // POST /save
+QueryController<LIST_ITEM, DETAIL_ITEM>  // GET/POST /list, GET /detail/{id}
+RemoveController                       // GET /remove/{id}
+
+SimpleController<SAVE_ITEM, LIST_ITEM, DETAIL_ITEM>
+```
+
+**SimpleControllerSupport 实现**：
+- 调用 Service 方法
+- 通过 Mapper 转换 DTO ↔ Entity
+- 封装 GlobalResponse
+- 扩展点：实现 `saveItemMapper()`, `listItemMapper()`, `detailItemMapper()`
+
+### 查询条件
+
+**Query 结构**：`Query(query: Queryable, sort: List<Sortable>, page: Pageable)`
+
+**QueryParser**：抽象类定义解析接口，`JpaQueryParser` 转换为 JPA Predicate
+
+**支持操作**：
+
+| 类别 | 操作 |
+|---|---|
+| 空值 | nullEqual, notNullEqual, empty, notEmpty |
+| 相等 | equal, notEqual |
+| 模糊 | like, notLike, contain, notContain |
+| 前后缀 | startWith, endWith, notStartWith, notEndWith |
+| 比较 | great, less, greatEqual, lessEqual |
+| 区间 | between, notBetween |
+| 集合 | inside, notInside |
+
+**实现**：JPA CriteriaBuilder 构建，支持多级字段路径（如 `user.name`），自动类型转换（枚举、LocalDateTime）
+
+### 响应格式
+
+```java
+GlobalResponse<T>(status, message, data)
+// status: 0 成功, 500 失败
+// 列表: data = ListItem(items, total)
+// 详情: data = DetailItem(item)
+```
+
+## 技术细节
+
+### 雪花算法
+
+`SnowflakeHelper`：64 位 Long，1 位符号 + 41 位时间戳 + 10 位机器 ID + 12 位序列号
+
+`SnowflakeIdGenerator`：实现 `IdentifierGenerator`，持久化时调用 `SnowflakeHelper.next()`
+
+### 部分更新
+
+Fenix `saveOrUpdateByNotNullProperties()`：
+- 自动判断 INSERT/UPDATE
+- 仅更新非 null 字段
+
+### 命名策略
+
+`PhysicalNamingStrategySnakeCaseImpl`：camelCase → snake_case
+
+### 注解处理器
+
+执行顺序：lombok → hibernate-jpamodelgen → querydsl-apt → mapstruct-processor
+
+生成：getter/setter、JPA 元模型（_Entity）、QueryDSL Q 类（QEntity）、MapStruct Mapper
+
+## 工具类
+
+### DatabaseHelper
+
+```java
+// 生成 DDL
+generateDDL(entityPackages, ddlFilePath, dialect, jdbc, username, password, driver)
+
+// 生成脚手架
+generateBasicFiles(entityPackages, projectRootPackage, projectRootPath, override)
+```
+
+### SnowflakeHelper
+
+```java
+Long id = SnowflakeHelper.next();
+```
+
+## 扩展指南
+
+### 软删除
+
+1. 创建 `SoftDeleteEntity extends SimpleEntity`，添加 `deleted` 字段
+2. 重写 `commonPredicates()` 返回 `deleted = false` 条件
+3. 覆盖 `remove()` 改为更新 `deleted` 字段
+
+### 多租户
+
+1. 创建 `TenantEntity extends SimpleEntity`，添加 `tenantId` 字段
+2. 重写 `commonPredicates()` 添加租户过滤
+3. ThreadLocal 或 Spring Security 存储当前租户
+
+### 审计字段
+
+在 `SimpleEntity` 添加 `createdBy`, `modifiedBy`，配合 Spring Security 获取当前用户
+
+### 自定义查询操作符
+
+1. `Query.Queryable` 添加字段
+2. `QueryParser` 添加抽象方法
+3. `JpaQueryParser` 实现转换为 Predicate
+
+## 测试
+
+- H2 内存数据库
+- `@DataJpaTest` 测试 Repository
+- `@WebMvcTest` 测试 Controller
+- 测试用例：`src/test/java/.../integration/`
+
+## 依赖
+
+核心：spring-boot-starter-data-jpa, fenix-spring-boot-starter:4.0.0, querydsl-jpa:7.1, mapstruct:1.6.3
+
+传递：spring-boot-service-template-common
+
+## 注意事项
+
+- 事务：写操作 `@Transactional(rollbackFor = Throwable.class)`，读操作 `@Transactional(readOnly = true)`
+- 异常：不使用全局处理器，直接抛出
+- 性能：批量操作使用批量方法
+- 线程安全：GlobalResponse 用 record 保证不可变，SnowflakeHelper 用原子变量

+# Database 模块使用指南
+
+单表 CRUD → REST 接口快速实现框架。
+
+## 使用模式
+
+### Web 应用
+
+引入 database 模块，创建 Entity → Repository → Service → Controller，实现 REST 接口。
+
+### 非 Web 应用
+
+**无需引入 web 依赖**（database 模块的 `spring-boot-starter-web` scope 为 `provided`）。
+
+仅使用 Entity → Repository → Service，直接注入 Service 使用：
+
+```java
+@SpringBootApplication
+public class Application implements CommandLineRunner {
+  @Autowired
+  private EmployeeService service;
+  
+  @Override
+  public void run(String... args) {
+    Employee emp = new Employee();
+    emp.setName("张三");
+    Long id = service.save(emp);
+    Employee found = service.detail(id);
+    List<Employee> list = service.list();
+  }
+}
+```
+
+适用：批处理、定时任务、数据迁移、命令行应用、后台服务。
+
+## 快速开始
+
+### 1. 添加依赖
+
+```xml
+<dependency>
+  <groupId>com.lanyuanxiaoyao</groupId>
+  <artifactId>spring-boot-service-template-database</artifactId>
+</dependency>
+```
+
+### 2. 创建实体
+
+```java
+@Getter @Setter
+@ToString(callSuper = true)
+@FieldNameConstants
+@Entity
+@Table(name = "employee")
+public class Employee extends SimpleEntity {
+  @Column(comment = "员工姓名", nullable = false)
+  private String name;
+  
+  @Column(comment = "部门ID")
+  private Long departmentId;
+  
+  @Column(comment = "邮箱")
+  private String email;
+}
+```
+
+继承 `SimpleEntity` 自动获得 `id`（雪花算法）、`createdTime`、`modifiedTime`（自动填充）。
+
+### 3. 创建 Repository
+
+```java
+@Repository
+public interface EmployeeRepository extends SimpleRepository<Employee> {}
+```
+
+继承能力：CRUD、分页、Specification、QueryDSL、Example。
+
+### 4. 创建 Service
+
+```java
+@Slf4j
+@Service
+public class EmployeeService extends SimpleServiceSupport<Employee> {
+  public EmployeeService(EmployeeRepository repository) {
+    super(repository);
+  }
+}
+```
+
+自动获得完整 CRUD 能力。
+
+### 5. 创建 Controller（Web 应用）
+
+```java
+@Slf4j
+@RestController
+@RequestMapping("employee")
+public class EmployeeController 
+    extends SimpleControllerSupport<Employee, EmployeeController.SaveItem, EmployeeController.ListItem, EmployeeController.DetailItem> {
+  
+  private final EmployeeService service;
+  
+  public EmployeeController(EmployeeService service) {
+    super(service);
+    this.service = service;
+  }
+  
+  @Override
+  protected Function<SaveItem, Employee> saveItemMapper() {
+    return item -> {
+      Employee entity = new Employee();
+      entity.setId(item.id());
+      entity.setName(item.name());
+      entity.setDepartmentId(item.departmentId());
+      entity.setEmail(item.email());
+      return entity;
+    };
+  }
+  
+  @Override
+  protected Function<Employee, ListItem> listItemMapper() {
+    return entity -> new ListItem(
+      entity.getId(), entity.getName(), entity.getDepartmentId(), 
+      entity.getEmail(), entity.getCreatedTime()
+    );
+  }
+  
+  @Override
+  protected Function<Employee, DetailItem> detailItemMapper() {
+    return entity -> new DetailItem(
+      entity.getId(), entity.getName(), entity.getDepartmentId(), 
+      entity.getEmail(), entity.getCreatedTime(), entity.getModifiedTime()
+    );
+  }
+  
+  public record SaveItem(Long id, String name, Long departmentId, String email) {}
+  public record ListItem(Long id, String name, Long departmentId, String email, LocalDateTime createdTime) {}
+  public record DetailItem(Long id, String name, Long departmentId, String email, LocalDateTime createdTime, LocalDateTime modifiedTime) {}
+}
+```
+
+实现三个 Mapper：`saveItemMapper()`, `listItemMapper()`, `detailItemMapper()`
+
+## 代码生成
+
+```java
+DatabaseHelper.generateBasicFiles(
+  "com.example.entity",              // 实体包
+  "com.example",                     // 项目根包
+  "./src/main/java/com/example",     // 源码路径
+  false                              // 是否覆盖
+);
+```
+
+生成 Repository、Service、Controller。
+
+## API 接口（Web 应用）
+
+### POST /{entity}/save
+
+保存/更新实体。
+
+请求（新增）：
+```json
+{"name": "张三", "departmentId": 1, "email": "zhangsan@example.com"}
+```
+
+请求（更新）：
+```json
+{"id": 123456789, "name": "李四"}
+```
+
+响应：
+```json
+{"status": 0, "message": "OK", "data": 123456789}
+```
+
+特性：不传 id 为新增，传 id 为更新（仅更新非 null 字段）。
+
+### GET/POST /{entity}/list
+
+GET：获取全部列表
+
+POST：条件查询
+```json
+{
+  "query": {
+    "equal": {"departmentId": 1},
+    "like": {"name": "%张%"},
+    "greatEqual": {"createdTime": "2026-01-01 00:00:00"}
+  },
+  "sort": [{"column": "createdTime", "direction": "DESC"}],
+  "page": {"index": 1, "size": 20}
+}
+```
+
+响应：
+```json
+{"status": 0, "message": "OK", "data": {"items": [...], "total": 100}}
+```
+
+### GET /{entity}/detail/{id}
+
+响应：
+```json
+{"status": 0, "message": "OK", "data": {"id": 123, "name": "张三", ...}}
+```
+
+ID 不存在返回 500。
+
+### GET /{entity}/remove/{id}
+
+响应：
+```json
+{"status": 0, "message": "OK", "data": null}
+```
+
+## 查询条件
+
+### Query 结构
+
+```java
+Query(
+  query: Queryable,      // 查询条件
+  sort: List<Sortable>,  // 排序
+  page: Pageable         // 分页
+)
+```
+
+### 查询操作
+
+| 操作 | 类型 | 示例 |
+|---|---|---|
+| equal | Map | `{"name": "张三"}` |
+| notEqual | Map | `{"status": "DELETED"}` |
+| like | Map | `{"name": "%张%"}` |
+| contain | Map | `{"name": "张"}` → `%张%` |
+| startWith | Map | `{"name": "张"}` → `张%` |
+| endWith | Map | `{"name": "三"}` → `%三` |
+| great/greatEqual | Map | `{"age": 18}` |
+| less/lessEqual | Map | `{"age": 60}` |
+| between | Map | `{"age": {"start": 18, "end": 60}}` |
+| inside | Map | `{"id": [1, 2, 3]}` |
+| notInside | Map | `{"status": ["DELETED"]}` |
+| nullEqual | List | `["deletedAt"]` |
+| notNullEqual | List | `["email"]` |
+
+### 排序
+
+```json
+{"sort": [{"column": "createdTime", "direction": "DESC"}]}
+```
+
+direction: `ASC` 升序，`DESC` 降序
+
+### 分页
+
+```json
+{"page": {"index": 1, "size": 20}}
+```
+
+index 从 1 开始，默认 `(1, 10)`，无排序默认 `createdTime DESC`
+
+## 高级用法
+
+### 扩展 Service
+
+```java
+@Service
+public class EmployeeService extends SimpleServiceSupport<Employee> {
+  private final EmployeeRepository repository;
+  
+  public EmployeeService(EmployeeRepository repository) {
+    super(repository);
+    this.repository = repository;
+  }
+  
+  // 自定义方法
+  public List<Employee> findByDepartmentId(Long departmentId) {
+    return repository.findAll(
+      (root, query, builder) -> builder.equal(root.get("departmentId"), departmentId)
+    );
+  }
+  
+  // 全局过滤条件
+  @Override
+  protected Predicate commonPredicates(Root<Employee> root, CriteriaQuery<?> query, CriteriaBuilder builder) {
+    return builder.equal(root.get("deleted"), false);  // 软删除过滤
+  }
+}
+```
+
+### QueryDSL 查询
+
+```java
+public List<Employee> findActiveEmployees() {
+  QEmployee q = QEmployee.employee;
+  return repository.findAll(q.status.eq("ACTIVE").and(q.deleted.isFalse()));
+}
+```
+
+### MapStruct Mapper
+
+```java
+@Mapper
+public interface EmployeeMapper {
+  Employee toEntity(SaveItem item);
+  ListItem toListItem(Employee entity);
+  DetailItem toDetailItem(Employee entity);
+}
+
+// Controller 中使用
+@Override
+protected Function<SaveItem, Employee> saveItemMapper() {
+  return mapper::toEntity;
+}
+```
+
+## 实体设计
+
+### 字段类型
+
+- ID: `Long`（雪花算法）
+- 时间: `LocalDateTime`
+- 金额: `BigDecimal`
+- 枚举: Java enum（存储为字符串）
+- 布尔: `Boolean`
+
+### 关联关系
+
+```java
+@Entity
+public class Order extends SimpleEntity {
+  @ManyToOne
+  @JoinColumn(name = "customer_id")
+  private Customer customer;
+  
+  @OneToMany(mappedBy = "order", fetch = FetchType.LAZY)
+  private List<OrderItem> items;
+}
+```
+
+注意：谨慎使用 `@OneToMany`，可能导致 N+1 问题。
+
+### 索引
+
+```java
+@Entity
+@Table(name = "employee", indexes = {
+  @Index(name = "idx_department", columnList = "department_id")
+})
+public class Employee extends SimpleEntity { ... }
+```
+
+## 工具类
+
+### DatabaseHelper
+
+```java
+// 生成 DDL
+DatabaseHelper.generateDDL(
+  "com.example.entity", "./sql", MySQL8Dialect.class,
+  "jdbc:mysql://localhost:3306/test", "root", "password",
+  com.mysql.cj.jdbc.Driver.class
+);
+```
+
+### SnowflakeHelper
+
+```java
+Long id = SnowflakeHelper.next();
+```
+
+## 常见问题
+
+**Q: 非 Web 应用如何使用？**
+
+A: 不引入 web 依赖，创建 Entity → Repository → Service，直接注入 Service 使用。
+
+**Q: 如何实现软删除？**
+
+A: 添加 `deleted` 字段，重写 `commonPredicates()` 过滤，覆盖 `remove()` 改为更新。
+
+**Q: 如何处理复杂查询？**
+
+A: 使用 QueryDSL 或 Repository `@Query` 方法：
+```java
+@Query("SELECT e FROM Employee e WHERE e.departmentId = :deptId")
+List<Employee> findByDepartment(@Param("deptId") Long deptId);
+```
+
+**Q: 如何批量插入？**
+
+A: `service.save(entities)` 或 `repository.saveAll(entities)`
+
+**Q: 查询条件支持关联对象吗？**
+
+A: 支持，使用多级路径如 `"department.name"`
+
+## 最佳实践
+
+1. DTO 设计：SaveItem 可修改字段，ListItem 列表字段，DetailItem 完整字段
+2. 事务：Service 方法已加事务，无需重复
+3. 性能：列表查询避免关联对象，使用投影或 DTO
+4. 代码生成：初期脚手架生成，后期手动调整

- * 该类实现了SimpleService接口，提供实体的增删改查等基本操作。
- * 通过继承此类，可以快速实现常见的业务逻辑功能，包括：
- * <ul>
- *   <li>实体的保存和更新（支持部分字段更新）</li>
- *   <li>实体的条件查询和分页查询</li>
- *   <li>实体的详情查询（多种方式）</li>
- *   <li>实体的删除操作（支持批量删除）</li>
- *   <li>动态查询条件构建</li>
- * </ul>
- * </p>
- *
- * <h3>设计特点</h3>
- * <ul>
- *   <li>泛型设计，支持任意实体类型</li>
- *   <li>事务管理，确保数据一致性</li>
- *   <li>动态查询条件，支持复杂的业务查询</li>
- *   <li>部分更新，只更新非空字段</li>
- *   <li>可扩展的查询条件构建</li>
- * </ul>
