1.问题分析
代码：
- IpsegmentVo

public class IpsegmentVo extends Ipsegment {
private String planName;// 关联的应用名称
private Long statusValue; // 状态值
private Long runStatusValue; // 业务状态
private Long readyStatusValue; // 预占状态
private int childrenCount; // 子节点个数
private Integer autoBasicMsg;//是否自动生成基本信息
private List<IpsegmentVo> children = new ArrayList<>();//子节点
private Boolean _checked = false;//选中当前项（true:是，false:否）
private Boolean _disabled = false;//禁止选择当前项（true:是，false:否）

}

}
带下划线的字段

- 调试模式：
查看后台的返回值
带下划线的变量被成功赋值
查看前端页面
前端状态显示不正确
查看请求结果
查看请求返回的结果
返回结果中，带下划线的变量，下划线丢失
发现返回结果中，带下划线的变量，下划线丢失
正是由于返回的结果中变量名丢失下划线，前端需要的参数对应不上，导致前端页面显示的状态不正确
2.解决办法，很明显是后台返回的数据在进行json序列化的时候，带下划线的变量名被去除了下划线，由此我们只需要在带下划线的变量名上指定json序列化的名称即可
解决方案：在带下划线的变量名上使用@JSONField(name = " ")注解，指定Json序列化时，该变量的名称
代码：
- IpsegmentVo
package com.sccl.modules.data.ipsegment.domain;
import com.alibaba.fastjson.annotation.JSONField;
import java.util.ArrayList;
import java.util.List;
/**
* Create by wangbin
* 2019-08-14-19:21
*/
public class IpsegmentVo extends Ipsegment {
private String planName;// 关联的应用名称
private Long statusValue; // 状态值
private Long runStatusValue; // 业务状态
private Long readyStatusValue; // 预占状态
private int childrenCount; // 子节点个数
private Integer autoBasicMsg;//是否自动生成基本信息
private List<IpsegmentVo> children = new ArrayList<>();//子节点
@JSONField(name = "_checked") //在属性的setter和getter方法上使用注解@JSONField(name="_id"),为其指定要序列化和反序列化后的属性名，getter是序列化为json，setter是反序列化为java对象。通过此注解解决转json时，变量名下划线丢失的情况
private Boolean _checked = false;//选中当前项（true:是，false:否）
@JSONField(name = "_disabled")
private Boolean _disabled = false;//禁止选择当前项（true:是，false:否）
public Boolean get_checked() {
return _checked;
}
public void set_checked(Boolean _checked) {
this._checked = _checked;
}
public Boolean get_disabled() {
return _disabled;
}
public void set_disabled(Boolean _disabled) {
this._disabled = _disabled;
}
public Integer getAutoBasicMsg() {
return autoBasicMsg;
}
public void setAutoBasicMsg(Integer autoBasicMsg) {
this.autoBasicMsg = autoBasicMsg;
}
public String getPlanName() {
return planName;
}
public void setPlanName(String planName) {
this.planName = planName;
}
public Long getStatusValue() {
return statusValue;
}
public void setStatusValue(Long statusValue) {
this.statusValue = statusValue;
}
public Long getRunStatusValue() {
return runStatusValue;
}
public void setRunStatusValue(Long runStatusValue) {
this.runStatusValue = runStatusValue;
}
public Long getReadyStatusValue() {
return readyStatusValue;
}
public void setReadyStatusValue(Long readyStatusValue) {
this.readyStatusValue = readyStatusValue;
}
public int getChildrenCount() {
return childrenCount;
}
public void setChildrenCount(int childrenCount) {
this.childrenCount = childrenCount;
}
public List<IpsegmentVo> getChildren() {
return children;
}
public void setChildren(List<IpsegmentVo> children) {
this.children = children;
}
}
通过 @JSONField注解指定了带下划线字段转json格式时的名称
查看请求结果：
带下划线的变量按照设置的名称转json成功
返回的数据中，下划线变量的按照指定的名称转换成功，没有丢失下划线
前端页面：
勾选状态表示正确
