@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:
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;
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<Role> 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<Role> getRoles() {
return roles;
} public void setRoles(List<Role> 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。
