对于最新稳定版本，请使用Spring Framework 7.0.1！spring-doc.cadn.net.cn

JacksonJSON

Spring 支持Jackson JSON 库。spring-doc.cadn.net.cn

JSON 视图

参见Servlet栈中的等价物spring-doc.cadn.net.cn

Spring WebFlux 为 Jackson 的序列化视图提供了内置支持 这只允许渲染所有字段的子集对象.用于@ResponseBody或响应实体控制器的方法，你可以用Jackson的@JsonView用于激活序列化视图类的注释，如下示例所示：spring-doc.cadn.net.cn

@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
}
@JsonView允许多个视图类数组，但每个只能指定一个 控制器方法。如果需要激活多个视图，使用复合界面。
