@JsonProperty @JsonIgnoreProperties

Question

json에없는이 생성자에이 새 파일을 추가 할 수 없어서 오류 아래 누군가가 나를 도와주세요. 나는 두 개의 주석 @JsonIgnoreProperties을 시도하고 @JsonIgnore 및 @JsonIgnoreProperties (ignoreUnknown = TRUE) 및 클래스 수준 및 생성자 수준은

다음은 내 코드 및 오류 세부 사항은

을 만들 // 같은

public static class Location { 
     private String a; 
     @Wither private int b; 
     @Wither private int c; 
     @Wither private int d; 
     @Wither private int newFiled; //which not there in json 

를 따릅니다 한

@JsonCreator 
    public Location(@JsonProperty("A") String a, 
          @JsonProperty("B") int b, 
          @JsonProperty("C") int b, 
          @JsonProperty("D") int d, 
          int newFiled) { 
      this.a = a; 
      this.b = b; 
      this.c = c; 
      this.d = d; 
      this.newFiled = newFiled; 
     } 

     public int newFiled() { 
      return a+b+c; 
        }

Answer 1

필드 레벨에 @JsonIgnore 주석을 추가 할 수 있습니다. 또는 생성자에서 제거하고 setter 메서드를 사용하여 값을 할당 할 수 있습니다.

@JsonCreator 
    public Location(@JsonProperty("A") String a, 
          @JsonProperty("B") int b, 
          @JsonProperty("C") int b, 
          @JsonProperty("D") int d) { 
      this.a = a; 
      this.b = b; 
      this.c = c; 
      this.d = d; 
     } 

     public int setNewFiled(int newFiled) { 
        this.newFiled = newFiled; 
     }
