登陆认证  
 **整合shiro**  
1 添加依赖

<dependency>
    	<groupId>org.apache.shiro</groupId>
    	<artifactId>shiro-spring</artifactId>
    </dependency>

2 web.xml中注册

<filter>
    	<filter-name>shiroFilter</filter-name>
    	<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> 
    	
    	<init-param>
    		<param-name>targetFilterLifecycle</param-name>
    		<param-value>true</param-value>
    	</init-param> 
    	
    	<init-param>
    		<param-name>targetBeanName</param-name>
    		<param-value>shiro</param-value>
    	</init-param>
    	</filter>
    	<filter-mapping>
    		<filter-name>shiroFilter</filter-name>
    		<url-pattern>/*</url-pattern>
    	</filter-mapping>

3 自定义Realm

//自定义的Realm
    public class MyRealm extends AuthorizingRealm{ 
    
    	 //认证的方法
    	@Override
    	protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException { 
    		// TODO Auto-generated method stub
    		return null;
    	}
    	
    	//授权的方法
    	@Override
    	protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) { 
    		// TODO Auto-generated method stub
    		return null;
    	}
    
    }

4 添加shiro的配置文件

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.2.xsd">

        		<bean class="org.apache.shiro.authc.credential.HashedCredentialsMatcher">

        			<property name="hashIterations" value="1024"/>
        		</bean>
        	</property>
        </bean>
        
        
        <bean class="org.apache.shiro.web.mgt.DefaultWebSecurityManager" id="securityManager">

            <property name="loginUrl" value="/login.do"/>
            
            <property name="successUrl" value="/home"/>
            
            <property name="unauthorizedUrl" value="/jsp/refuse.jsp"/>
            
            <property name="filterChainDefinitions">
                <value>
                    
                     / = anon
                    /login = anon
                    /images/** = anon
                    /css/** = anon
                    /js/** = anon
                    /lib/** = anon
                    /login.do = authc
                    /** = authc
                </value>
            </property>
        </bean>
    </beans>

@Controller
    public class PageController { 
    
    	//根据URL自动调对应的.jsp
    	@RequestMapping("/{path}")
    	public String goPage(@PathVariable String path){ 
    		return path;
    	}
    }

2 登陆认证  
UserServiceImpl中修改query方法

@Override
    	public List<User> query(User user) { 
    		UserExample example = new UserExample();
    		if(user != null){ 
    			Criteria criteria = example.createCriteria();
    			if(StringUtils.isNotEmpty(user.getUserName())){ 
    				//根据账号查询
    				criteria.andUserNameEqualTo(user.getUserName());
    			}
    		}
    		return userMapper.selectByExample(example);
    	}

自定义Realm中完成认证逻辑

package com.i.shiro;
    
    //自定义的Realm 实现认证和授权操作
    public class SecurityRealm extends AuthorizingRealm { 
    
    	@Resource
    	private IUserService userService;
    	
    	//授权的方法
    	@Override
    	protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) { 
    		return null;
    	}
    
    	//认证的方法
    	@Override
    	protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException { 
    		if(token instanceof UsernamePasswordToken){ 
    			//获取提交的账号
    			UsernamePasswordToken t = (UsernamePasswordToken) token;
    			//获取登陆的账号
    			String userName = t.getUsername();
    			User user = new User();
    			user.setUserName(userName);
    			//登陆操作
    			List<User> list = userService.query(user);
    			if(list == null || list.size() > 1){ 
    				//参数不存在或用户过多都返回null
    				return null;
    			}
    			//表示账号存在
    			user = list.get(0);
    			SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(user,
    													user.getPassword(),
    													new SimpleByteSource(user.getU1())//盐值
    													,"securityRealm");
    			return info;
    		}
    		return null;
    	}
    }

controller层逻辑

@Controller
    public class LoginController { 
    
    	//设置登陆失败跳转的页面,获取失败信息
    	@RequestMapping("/login.do")
    	public String login(HttpServletRequest request,Model m){ 
    		//获取错误的异常信息
    		Object obj = request.getAttribute(FormAuthenticationFilter.DEFAULT_ERROR_KEY_ATTRIBUTE_NAME);
    		if(obj != null){ 
    			System.out.println(obj.toString());
    		}
    		if(UnknownAccountException.class.getName().equals(obj)){ 
    			m.addAttribute("LOGIN_ERROR","账号有误");
    		}else if(IncorrectCredentialsException.class.getName().equals(obj)){ 
    			m.addAttribute("LOGIN_ERROR","密码有误");
    		}else{ 
    			m.addAttribute("LOGIN_ERROR","其他错误");
    		}
    		return "login";
    	}

认证登陆信息

<form action="/login.do" method="post">
    		    <ul>
    			    <li><input name="username" type="text" class="loginuser" value="admin" /></li>
    			    <li><input name="password" type="text" class="loginpwd" value="1" /></li>
    			    <li>
    			    	<input type="submit" class="loginbtn" value="登录"/>
    				    <label>
    				    	<input name="" type="checkbox" value="" checked="checked" />记住密码
    				    </label>
    				    <label>
    				    	<span style="color:red ">${LOGIN_ERROR}</span>
    				    </label>
    			    </li>
    		    </ul>
        	</form>

**退出功能**

LoginController中添加退出方法

//退出
    	@RequestMapping("/logout.do")
    	public String logout(){ 
    		SecurityUtils.getSubject().logout();
    		return "login";
    	}
    }
