Spring MVC Rest Service JSON-將布爾值的默認值設置為true

Question

將boolean值的默認值設置為true

這就是其中具有布爾值的dto clas。

DTO班

public class SensitivityDto extends AuditableEntity implements Serializable {
    private static final long serialVersionUID = 1L;


    private long sensitivityId;
    @JsonIgnore
    private boolean isSelected;

    public SensitivityDto() {
    }
    /** other getter/setters */
    public boolean isIsSelected() {
        return isSelected;
    }

    public void setIsSelected(boolean isSelected) {
        this.isSelected = isSelected;
    }

}

輸入json

{
  "sensitivity": {
    "sensitivityId": 100,
    "isSelected": "true", // if not passing this field always its treated as null.

  }
}

調節器

public @ResponseBody ResultDecorator saveLabResultCultureDetails(@RequestBody SensitivityDto sensitivityDto) throws  Exception {

}

如何將布爾值默認設置為true， 所以如果json中不存在此值，則它不應為false，而應為true。

Answer 1

關於什么？

@JsonIgnore
private boolean isSelected = true;

從評論：

那么即使我在json中發送false，其takng也為true

您必須刪除@JsonIgnore並使用@JsonAutoDetect ，如下所示：

import java.io.Serializable;
import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.JsonAutoDetect.Visibility;

@JsonAutoDetect(fieldVisibility = Visibility.ANY, getterVisibility = Visibility.NONE, setterVisibility = Visibility.NONE)
public class SensitivityDto extends AuditableEntity implements Serializable {
    private static final long serialVersionUID = 1L;

    private long sensitivityId;


    private boolean isSelected = true;

    public SensitivityDto() {
    }

    /** other getter/setters */
    public boolean isIsSelected() {
        return isSelected;
    }

    public void setIsSelected(boolean isSelected) {
        this.isSelected = isSelected;
    }

}
