2.创建 RealmCustom继承 AuthorizingRealm
package com.made.md.shiro;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
public class RealmCustom extends AuthorizingRealm{
/**
* 返回 权限信息
*/
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principal) {
// TODO Auto-generated method stub
// 1. 获取 用户名
String userName = principal.getPrimaryPrincipal().toString();
// 2. 根据 用户名 调用数据库 查看该用户下的角色 以及 权限
// 3. 添加 角色 以及 权限
SimpleAuthorizationInfo simpleInfo = new SimpleAuthorizationInfo();
simpleInfo.addRole("admin");
simpleInfo.addStringPermission("ma1");
return simpleInfo;
}
/**
* 验证登录信息
* 返回 登录信息
*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
// TODO Auto-generated method stub
// 1.获取 用户名 密码
String userName = token.getPrincipal().toString();
String password = new String((char[])token.getCredentials());
// 2. 通过 调用数据库 来验证 登录信息是否正确
// 3. 如果 一切 正确 返回
SimpleAuthenticationInfo simpleInfo = new SimpleAuthenticationInfo(userName, password, getName());
return simpleInfo;
}
}
3.创建 applicationContext-shiro.xml
