懷着對java的熱情，在學習基本的servlet和jsp jdbc以後 學習了hibernate springmvc spring下面講述一下心得
這裏以最簡單的角色控制權限，通過隊伍管理，爲例子 ，正常的是用戶和角色多對多，角色和權限多對多，5張表 但是處理的邏輯比較簡單就直接用戶和角色多對1，角色和權限多對多 ，然後用戶和隊伍多對多實現，hibernate採用xml開發，這裏不用註解
這裏主要是這幾個類 User類 Role角色類 Authority權限類 這裏寫了information爲User類的詳細信息 Group爲User所在的隊伍
這裏省略information和Group這2個類
首先是User類
package com.caicai.entity;
import java.io.Serializable;
public class User implements Serializable{
private Integer uid;
private String uname;
private String upassword;
private String uphoto;
private Role urole;
private Group ugroup;
private Information uinformation;
public Information getUinformation() {
return uinformation;
}
public void setUinformation(Information uinformation) {
this.uinformation = uinformation;
}
public Integer getUid() {
return uid;
}
public void setUid(Integer uid) {
this.uid = uid;
}
public String getUname() {
return uname;
}
public void setUname(String uname) {
this.uname = uname;
}
public String getUpassword() {
return upassword;
}
public void setUpassword(String upassword) {
this.upassword = upassword;
}
public String getUphoto() {
return uphoto;
}
public void setUphoto(String uphoto) {
this.uphoto = uphoto;
}
public Role getUrole() {
return urole;
}
public void setUrole(Role urole) {
this.urole = urole;
}
public Group getUgroup() {
return ugroup;
}
public void setUgroup(Group ugroup) {
this.ugroup = ugroup;
}
public User(Integer uid, String uname, String upassword, String uphoto,
Role urole, Group ugroup) {
super();
this.uid = uid;
this.uname = uname;
this.upassword = upassword;
this.uphoto = uphoto;
this.urole = urole;
this.ugroup = ugroup;
}
public User() {
super();
}
public User(String uname, String upassword) {
super();
this.uname = uname;
this.upassword = upassword;
}
public User(Integer uid, String uname, String upassword, String uphoto,
Role urole, Group ugroup, Information uinformation) {
super();
this.uid = uid;
this.uname = uname;
this.upassword = upassword;
this.uphoto = uphoto;
this.urole = urole;
this.ugroup = ugroup;
this.uinformation = uinformation;
}
}User類的xml
