Java中返回体去掉指定字段

在定义的返回体结构中需要忽略指定字段可以使用如下方法：例如
@Getter(onMethod = @__( @JsonIgnore))
private String salt;

import com.fasterxml.jackson.databind.ObjectMapper;

public class testC {
 public static void main(String[] args) throws IOException {
        SysUserEntity sy = new SysUserEntity();
        sy.setUuid("1");
        sy.setUserId(1L);
        sy.setUsername("张三");
        sy.setSalt("1111111");
        sy.setPassword("1234");
        System.out.println(new ObjectMapper().writevalueAsString(sy));
   } 
}

import com.fasterxml.jackson.annotation.JsonIgnore;
import com.fasterxml.jackson.annotation.JsonProperty;
import lombok.Data;
import lombok.Getter;
import net.sf.json.JSONObject;
import org.springframework.util.ObjectUtils;

import javax.validation.constraints.Email;
import javax.validation.constraints.NotBlank;
import java.io.Serializable;
import java.util.Date;
import java.util.List;
import java.util.Objects;

@Data

public class SysUserEntity implements Serializable {
    private static final long serialVersionUID = 1L;

    
    private Long userId;

    
    private String username;

    
    @Getter(onMethod = @__( @JsonIgnore))
    private String password;

    
    @Getter(onMethod = @__( @JsonIgnore))
    private String salt;

    private String uuid;
