+# 一、JsonView
+  JsonView 是 Jackson 提供的注解，用于控制对象序列化/反序列化时包含哪些字段。可以实现： 
+- 不同接口返回不同字段
+- 敏感字段过滤
+- 前后端数据分离
+
+## 1.1 添加依赖
+```xml
+<dependencies>
+    <!-- Spring Boot Web -->
+    <dependency>
+        <groupId>org.springframework.boot</groupId>
+        <artifactId>spring-boot-starter-web</artifactId>
+    </dependency>
+</dependencies>
+```
+
+## 1.2 使用
+1. 定义视图接口
+```java
+// JsonView 视图定义
+public class Views {
+    // 基础视图 - 所有接口都包含的字段
+    public interface Basic {}
+    
+    // 返回给前端时使用
+    public interface Response extends Basic {}
+    
+    // 接收前端数据时使用
+    public interface Request extends Basic {}
+    
+    // 管理视图 - 包含所有字段
+    public interface AdminView extends ReadView {}
+}
+```
+
+2. Dto对象使用JsonView
+```java
+@Data
+public class UserDTO {
+    @JsonView(Views.Response.class)
+    private Long id;
+    
+    @JsonView(Views.Request.class)
+    @NotBlank(message = "密码不能为空")
+    @Size(min = 6, message = "密码至少6位")
+    private String password;
+    
+    @JsonView(Views.Basic.class)
+    @NotBlank(message = "用户名不能为空")
+    private String username;
+    
+    @JsonView(Views.Basic.class)
+    @Email(message = "邮箱格式不正确")
+    private String email;
+    
+    @JsonView(Views.Basic.class)
+    private String nickname;
+
+    @JsonView(AdminView.class)
+    private Boolean isActive;
+}
+```
+
+3. Controller中使用
+```java
+@RestController
+@RequestMapping("/api/users")
+public class UserController {
+    
+    @Autowired
+    private UserService userService;
+    
+    @PostMapping
+    @JsonView(UserDTO.Response.class)
+    public UserDTO createUser(@RequestBody @JsonView(UserDTO.Request.class) UserDTO userDTO) {
+        return userService.createUser(userDTO);
+    }
+    
+    @PutMapping("/{id}")
+    @JsonView(UserDTO.Response.class)
+    public UserDTO updateUser(@PathVariable Long id,
+                              @RequestBody @JsonView(UserDTO.Request.class) UserDTO userDTO) {
+        return userService.updateUser(id, userDTO);
+    }
+    
+    @GetMapping("/{id}")
+    @JsonView(UserDTO.Response.class)
+    public UserDTO getUser(@PathVariable Long id) {
+        return userService.getUserById(id);
+    }
+    
+    @GetMapping("/{id}/admin")
+    @JsonView(UserDTO.AdminView.class)
+    public UserDTO getAdminUser(@PathVariable Long id) {
+        return userService.getAdminUserById(id);
+    }
+}
+```
+
+# 二、MapStruct
+&emsp;&emsp;MapStruct 是一个 Java 注解处理器，用于生成类型安全的 Bean 映射代码：
+- 编译时生成映射代码，无运行时性能损失
+- 类型安全
+- 支持复杂映射
+
+## 2.1 添加依赖
+```xml
+<properties>
+    <org.mapstruct.version>1.5.5.Final</org.mapstruct.version>
+</properties>
+
+<dependencies>
+    <dependency>
+        <groupId>org.mapstruct</groupId>
+        <artifactId>mapstruct</artifactId>
+        <version>${org.mapstruct.version}</version>
+    </dependency>
+</dependencies>
+
+<build>
+    <plugins>
+        <plugin>
+            <groupId>org.apache.maven.plugins</groupId>
+            <artifactId>maven-compiler-plugin</artifactId>
+            <version>3.11.0</version>
+            <configuration>
+                <annotationProcessorPaths>
+                    <path>
+                        <groupId>org.mapstruct</groupId>
+                        <artifactId>mapstruct-processor</artifactId>
+                        <version>${org.mapstruct.version}</version>
+                    </path>
+                </annotationProcessorPaths>
+            </configuration>
+        </plugin>
+    </plugins>
+</build>
+```
+
+## 2.2 使用
+```java
+import org.mapstruct.*;
+
+import java.util.List;
+import java.time.format.DateTimeFormatter;
+
+@Mapper
+public interface UserMapper {
+    
+    @Mapping(target = "name", source = "userName")        // 字段名不同
+    @Mapping(target = "phoneNumber", source = "phone")    // 字段名不同
+    @Mapping(target = "description", source = "remark")   // 字段名不同
+    @Mapping(target = "statusDesc", ignore = true)        // 需要特殊处理
+    @Mapping(target = "createTime", ignore = true)        // 需要格式化
+    UserDTO toDTO(User user);
+    
+    @Mapping(target = "userName", source = "name")
+    @Mapping(target = "phone", source = "phoneNumber")
+    @Mapping(target = "remark", source = "description")
+    @Mapping(target = "password", ignore = true)          // 密码不映射
+    User toEntity(UserDTO dto);
+    
+    // 列表映射
+    List<UserDTO> toDTOList(List<User> users);
+    
+    // 带默认值的映射
+    @Mapping(target = "name", source = "userName")
+    @Mapping(target = "phoneNumber", source = "phone")
+    @Mapping(target = "description", source = "remark", defaultValue = "暂无描述")
+    @Mapping(target = "statusDesc", expression = "java(convertStatus(user.getStatus()))")
+    @Mapping(target = "createTime", expression = "java(formatTime(user.getCreateTime()))")
+    UserDTO toDTOWithDefault(User user);
+    
+    // 自定义转换方法
+    default String convertStatus(Integer status) {
+        if (status == null) return "未知";
+        switch (status) {
+            case 0: return "禁用";
+            case 1: return "正常";
+            case 2: return "锁定";
+            default: return "未知";
+        }
+    }
+    
+    // 时间格式化方法
+    default String formatTime(LocalDateTime time) {
+        if (time == null) return "";
+        return time.format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"));
+    }
+}
+```
+
+&emsp;&emsp;需要执行`mvn compile`后检查`target/generated-sources`文件夹下是否存在生成的转换代码。
