Jackson JSON
Spring 为 Jackson JSON 库提供了支持。
JSON 视图
Spring WebFlux 为 Jackson 的序列化视图 提供了内置支持，它允许仅渲染 Object 中所有字段的一个子集。要在 @ResponseBody 或 ResponseEntity 控制器方法中使用它，您可以使用 Jackson 的 @JsonView 注解来激活一个序列化视图类，如以下示例所示：
-
Java
-
Kotlin
@RestController
public class UserController {
@GetMapping("/user")
@JsonView(User.WithoutPasswordView.class)
public User getUser() {
return new User("eric", "7!jd#h23");
}
}
public class User {
public interface WithoutPasswordView {};
public interface WithPasswordView extends WithoutPasswordView {};
private String username;
private String password;
public User() {
}
public User(String username, String password) {
this.username = username;
this.password = password;
}
@JsonView(WithoutPasswordView.class)
public String getUsername() {
return this.username;
}
@JsonView(WithPasswordView.class)
public String getPassword() {
return this.password;
}
}@RestController
class UserController {
@GetMapping("/user")
@JsonView(User.WithoutPasswordView::class)
fun getUser(): User {
return User("eric", "7!jd#h23")
}
}
class User(
@JsonView(WithoutPasswordView::class) val username: String,
@JsonView(WithPasswordView::class) val password: String
) {
interface WithoutPasswordView
interface WithPasswordView : WithoutPasswordView
