【问题描述】：

我有两个班级，A 和 B：

class A
    private int numberOne;
    private int numberTwo;
    public int getNumberOne() 
        return numberOne;
    
    public void setNumberOne(int numberOne) 
        this.numberOne = numberOne;
    
    public int getNumberTwo() 
        return numberTwo;
    
    public void setNumberTwo(int numberTwo) 
        this.numberTwo = numberTwo;
    
    

    class B extends A 

    private int numberThree;
    public int getNumberThree() 
        return numberThree;
    
    public void setNumberThree(int numberThree) 
        this.numberThree = numberThree;
    

我怎么能喜欢这样：

    ResponseEntity<A> someMethod()
        return new B(1,2,3);
    
json 
    
     "numberOne":"1",
     "numberTwo":"2"
    

    ResponseEntity<B> someMethod()
        return new B(1,2,3);
    
json 
    
     "numberOne":"1",
     "numberTwo":"2",
     "numberThree":"3"
     

如何在我想要的 Spring Boot 中使用 JSON 忽略？

【参考方案1】：

你创建了新的类

public class Views 
public static class Public 


public static class Internal extends Public 
 

A.类

public class A 

public A(int numberOne, int numberTwo) 
    this.numberOne = numberOne;
    this.numberTwo = numberTwo;


@JsonView(Views.Public.class)
private int numberOne;
@JsonView(Views.Public.class)
private int numberTwo;

public int getNumberOne() 
    return numberOne;


public void setNumberOne(int numberOne) 
    this.numberOne = numberOne;


public int getNumberTwo() 
    return numberTwo;


public void setNumberTwo(int numberTwo) 
    this.numberTwo = numberTwo;

B.类

public class B extends A

@JsonView(Views.Internal.class)
private int numberThree;

public B(int numberOne, int numberTwo) 
    super(numberOne, numberTwo);


public B(int numberOne, int numberTwo, int numberThree) 
    super(numberOne, numberTwo);
    this.numberThree = numberThree;


public int getNumberThree() 
    return numberThree;


public void setNumberThree(int numberThree) 
    this.numberThree = numberThree;

控制器

 @GetMapping("/a-method")
@JsonView(Views.Public.class)
public ResponseEntity<A> getA()
    return ResponseEntity.ok(new B(1,2,3));


@GetMapping("/b-method")
@JsonView(Views.Internal.class)
public ResponseEntity<B> getB()
    return ResponseEntity.ok(new B(1,2,3));

【讨论】：

谢谢兄弟，按照你的例子我用这个：@JsonView(A.class) 和@JsonView(B.class)
