我是springmvc加mysql加hibernate的环境，基础配置的东西就不写出来的，只把重点的写出来
1.数据表：一个三个表
(1) 用户表：
(2)对象表
(3)用户关于对象对应的权限表
2.model对象
UserAuth.java
public class UserAuth {
private String userName;
private Map<String, List<String>> userAuthMap;
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public Map<String, List<String>> getUserAuthMap() {
return userAuthMap;
}
public void setUserAuthMap(Map<String, List<String>> userAuthMap) {
this.userAuthMap = userAuthMap;
}
}@Entity
@Table(name = "auth_acc")
public class AuthAcc {
@Id
private String id;
@Column
private String userId;
@Column
private String objId;
@Column
private String authOperate;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getUserId() {
return userId;
}
public void setUserId(String userId) {
this.userId = userId;
}
public String getObjId() {
return objId;
}
public void setObjId(String objId) {
this.objId = objId;
}
public String getAuthOperate() {
return authOperate;
}
public void setAuthOperate(String authOperate) {
this.authOperate = authOperate;
}
}AuthObj.java
@Entity
@Table(name = "auth_obj")
public class AuthObj {
@Id
private String id;
@Column
private String name;
@Column
private String operate;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getOperate() {
return operate;
}
public void setOperate(String operate) {
this.operate = operate;
}
} @RequestMapping("authDemo")
public String authDemo(Map<String, Object> map) {
Map<String, Object> authObjMap = new HashMap<String, Object>();// 保存所有对象的所有操作权限
Map<String, String> objNmMap = new HashMap<String, String>();// 保存对象id对应的对象名,用于画面显示
List<AuthObj> authObjLst = testService.getAuthObjLst();// 得到有权限管理的所有对象
String operateKey = null;// 操作权限内容字母
String operate = null;// 操作权限内容
for (AuthObj mAuthObj : authObjLst) {
Map<String, String> operateMap = new HashMap<String, String>();// 操作权限内容Map
operate = mAuthObj.getOperate();// 操作权限内容
for (int i = 0; i < operate.length(); i++) {
operateKey = operate.substring(i, i + 1);
operateMap.put(operateKey, Constants.OPERATEMAP.get(operateKey));//把每个字母对应的名字保存在map中
}
authObjMap.put(mAuthObj.getId(), operateMap);//以对象的id为key,操作权限内容Map为value
objNmMap.put(mAuthObj.getId(), mAuthObj.getName());// 保存对象id对应的对象名,用于画面显示
}
map.put("mp", authObjMap);// 保存所有对象的所有操作权限
map.put("nmMp", objNmMap);// 保存对象id对应的对象名,用于画面显示
Map<String, List<String>> authAccMap = new HashMap<String, List<String>>();
String userId = "004";// 假设当前用户id为004
List<AuthAcc> authAccLst = testService.getAuthAccLstByUserid(userId);// 获取当前用户对应对象的权限
String authOperate = null;//当前用户的权限
for (AuthAcc mAuthAcc : authAccLst) {
List<String> authLst = new ArrayList<String>();//当前用户的权限,用一个list保存
authOperate = mAuthAcc.getAuthOperate();//当前用户的权限
for (int i = 0; i < authOperate.length(); i++) {
authLst.add(authOperate.substring(i, i + 1));//遍历权限,保存在一个list里
}
authAccMap.put(mAuthAcc.getObjId(), authLst);//以对象id为key,当前用户的权限为value,保存在一个map里
}
UserAuth mUserAuth = new UserAuth();
mUserAuth.setUserAuthMap(authAccMap);
map.put("vm", mUserAuth);
return "authDemoVw";
}
}public class Constants {
/**
* 定义每个字母对应的权限名称
*/
public final static Map<String, String> OPERATEMAP = new HashMap<String, String>();
static {
OPERATEMAP.put("c", "增加");
OPERATEMAP.put("r", "查询");
OPERATEMAP.put("u", "更改");
OPERATEMAP.put("d", "删除");
}

这篇文章只是先把用户所拥有的权限列表显示出来，权限的更新和权限的判断在后面的文章里会写
