shiro(四)项目开发中的配置、

配置拦截、过滤、验证请求

ShiroRealm类代码

 

package com.cms.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.authc.UsernamePasswordToken;
import org.apache.shiro.realm.Realm;

public class ShiroRealm implements Realm{

    @Override
    public AuthenticationInfo getAuthenticationInfo(AuthenticationToken arg0) throws AuthenticationException {
           /*获取用户名*/
        String username = arg0.getPrincipal().toString();
        /*获取密码，由于密码是进行了加密的，所以必须转为char数组再转String
        * 否则无法识别*/
        String password =String.valueOf((char [])arg0.getCredentials());
         if(null != username && null != password){
             return new SimpleAuthenticationInfo(username, password, getName());
         }else{
             return null;
         }
    }

    @Override
    public String getName() {
        // TODO Auto-generated method stub
        return "ShiroRealm";
    }
    /**
     * 判断当前认证方式是不是用户名和密码
     */
    @Override
    public boolean supports(AuthenticationToken arg0) {
        // TODO Auto-generated method stub
        return arg0 instanceof UsernamePasswordToken;
    }

}

 

登录的代码

        Subject subject = SecurityUtils.getSubject(); 
        Session session = subject.getSession();
        String attribute = (String)session.getAttribute("abc");
        System.out.println(attribute);
        try {
            data.put("username", "username");
            data.put("password", "password");
            PageData pd = userService.getUserByUsernameAndPassword(data);
            System.out.println(pd);
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        
        
        UsernamePasswordToken token = new UsernamePasswordToken("abc", "abc");         
        subject.login(token);
