@JsonIgnore的使用：
实体类中加@JsonIgnore注解
package com.baidu.entity; import com.fasterxml.jackson.annotation.JsonIgnore; import org.springframework.data.annotation.Transient; import java.io.Serializable; public class User implements Serializable{ private static final long serialVersionUID = 8121761080892505330L; private String username; @Transient @JsonIgnore private transient String password; public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } }
controller层：
@RequestMapping("/select")
@ResponseBody
public BaseResponse select(@RequestBody UserParam userParam){
//用户重置
userParam.setUsername("李雪雷2");
userParam.setPassword("666662");
try{
List<User> users = userService.select();
return BaseResponse.successCustom().setData(users).build();
}catch (Exception e){
e.printStackTrace();
return BaseResponse.failedCustom("系统异常").build();
}
}
页面代码：

前台：
前台接受到的json对象中已经忽略掉了password字段，只显示username。
