大家好，又见面了，我是你们的朋友全栈君。

@jsonignore的作用作用是json序列化时将java bean中的一些属性忽略掉,序列化和反序列化都受影响。

如下：

代码语言：javascript复制package com.hzboy.orm;

import java.util.List;

import javax.persistence.CascadeType;

import javax.persistence.Column;

import javax.persistence.Entity;

import javax.persistence.FetchType;

import javax.persistence.JoinColumn;

import javax.persistence.JoinTable;

import javax.persistence.ManyToMany;

import javax.persistence.ManyToOne;

import javax.persistence.Table;

import javax.persistence.Transient;

import org.codehaus.jackson.annotate.JsonIgnore;

import org.codehaus.jackson.annotate.JsonIgnoreProperties;

import org.codehaus.jackson.annotate.JsonManagedReference;

/**

* 系统用户实体类

* @author tinner

*

*/

@Entity(name = "com.hzboy.orm.User")

@Table(name = "sys_user")

@JsonIgnoreProperties({

"hibernateLazyInitializer", "handler"})

public class User extends BaseEntity {

/**

*

*/

private static final long serialVersionUID = -1343842065506227012L;

public User() {

}

public User(Integer id) {

this.id = id;

}

// 登录名

private String loginName;

// 密码123456-b594510740d2ac4261c1b2fe87850d08

private String pswd;

// 姓名

private String nickName;

// 性别

private Short sex;

// 年龄段

private String ageStage;

// 是否系统管理员

private boolean systemAdmin;

//联系电话

private String tel;

//Email

private String email;

//是否工程师

private Boolean isEnginner;

//是否前端客户 是则显示前台html,但同时保留后台相关模块

private Boolean isFrontUser;

//相关部门

private Department department;

//相关部门前台描述

private String departmentName;

private Integer departmentId;

//用户编号

private String userCode;

//附加用于导入

private String idCode;

//附加的部门信息 用于计算

private String departmentCode;

@Column(name = "login_name")

public String getLoginName() {

return loginName;

}

public void setLoginName(String loginName) {

this.loginName = loginName;

}

@Column(name = "pswd")

public String getPswd() {

return pswd;

}

public void setPswd(String pswd) {

this.pswd = pswd;

}

@Column(name = "nick_name")

public String getNickName() {

return nickName;

}

public void setNickName(String nickName) {

this.nickName = nickName;

}

@Column(name = "sex")

public Short getSex() {

return sex;

}

public void setSex(Short sex) {

this.sex = sex;

}

@Column(name = "age_stage")

public String getAgeStage() {

return ageStage;

}

public void setAgeStage(String ageStage) {

this.ageStage = ageStage;

}

@Column(name = "system_admin")

public boolean isSystemAdmin() {

return systemAdmin;

}

public void setSystemAdmin(boolean systemAdmin) {

this.systemAdmin = systemAdmin;

}

private List roles;

@ManyToMany(fetch = FetchType.LAZY, cascade = (CascadeType.REMOVE))

@JoinTable(name = "sys_user_role", joinColumns = { @JoinColumn(name = "user_id") }, inverseJoinColumns = { @JoinColumn(name = "role_id") })

public List getRoles() {

return roles;

}

public void setRoles(List roles) {

this.roles = roles;

}

private Integer[] roleIds;

@Transient

public Integer[] getRoleIds() {

return roleIds;

}

public void setRoleIds(Integer[] roleIds) {

this.roleIds = roleIds;

}

@Column(name="email")

public String getEmail() {

return email;

}

public void setEmail(String email) {

this.email = email;

}

@Column(name="is_enginner")

public Boolean getIsEnginner() {

return isEnginner;

}

public void setIsEnginner(Boolean isEnginner) {

this.isEnginner = isEnginner;

}

@Column(name="is_front_user")

public Boolean getIsFrontUser() {

return isFrontUser;

}

public void setIsFrontUser(Boolean isFrontUser) {

this.isFrontUser = isFrontUser;

}

public String getTel() {

return tel;

}

public void setTel(String tel) {

this.tel = tel;

}

@JsonIgnore

@ManyToOne(cascade = { CascadeType.PERSIST, CascadeType.MERGE }, fetch = FetchType.LAZY)

@JoinColumn(name="department_id")

public Department getDepartment() {

return department;

}

@JsonManagedReference

public void setDepartment(Department department) {

this.department = department;

}

@Transient

public String getDepartmentName() {

return departmentName;

}

public void setDepartmentName(String departmentName) {

this.departmentName = departmentName;

}

@Transient

public Integer getDepartmentId() {

return departmentId;

}

public void setDepartmentId(Integer departmentId) {

this.departmentId = departmentId;

}

@Column(name="user_code")

public String getUserCode() {

return userCode;

}

public void setUserCode(String userCode) {

this.userCode = userCode;

}

@Column(name="id_from_import")

public String getIdCode() {

return idCode;

}

public void setIdCode(String idCode) {

this.idCode = idCode;

}

public String getDepartmentCode() {

return departmentCode;

}

public void setDepartmentCode(String departmentCode) {

this.departmentCode = departmentCode;

}

}上个实体User中的 department属性就在getDepartment属性上加了 @JsonIgnore,这个时候从后台推数据到前台的时候,就会把department这个引用属性给忽略掉。
