spring+shiro 整合实例代码详解

一、添加相关依赖

<dependency>
   <groupId>org.apache.shiro</groupId>
   <artifactId>shiro-core</artifactId>
   <version>1.2.1</version>
  </dependency>
  <dependency>
   <groupId>org.apache.shiro</groupId>
   <artifactId>shiro-web</artifactId>
   <version>1.2.1</version>
  </dependency>
  <dependency>
   <groupId>org.apache.shiro</groupId>
   <artifactId>shiro-ehcache</artifactId>
   <version>1.2.1</version>
  </dependency>
  <dependency>
   <groupId>org.apache.shiro</groupId>
   <artifactId>shiro-spring</artifactId>
   <version>1.2.1</version>
  </dependency>
  <dependency>
   <groupId>commons-logging</groupId>
   <artifactId>commons-logging</artifactId>
   <version>1.2</version>
  </dependency>

二、编写代码

1、自定义realm

public class CommonRealm extends AuthorizingRealm {
 @Autowired
 private UserLoginService userLoginService;
 @Override
 public String getName() {
  return "CommonRealm";
 }
 //授权
 @Override
 protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
  String usernmae = (String) principals.getPrimaryPrincipal();
  List<String> permissions = new ArrayList<String>();
  if ("admin".equals(usernmae)) {
   permissions.add("admin:ee");
  }
  SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
  info.addStringPermissions(permissions);
  return info;
 }
 //身份认证
 @Override
 protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
  String username = (String) token.getPrincipal();
  User user = userLoginService.getUser(username);
  if (user == null) {
   return null;
  }
  SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(username, user.getPassword(), getName());
  return info;
 }
}

2、login controller

@Controller
public class UserAction {
 @Autowired
 private UserLoginService userLoginService;
 @RequestMapping("/login.do")
 public String userLogin(HttpServletRequest request, String username, String password) throws Exception {
  // 如果登陆失败从request中获取异常信息，shiroLoginFailure就是shiro异常类的全限定名
  String exceptionClassName = (String) request.getAttribute("shiroLoginFailure");
  if (exceptionClassName != null) {
   if (UnknownAccountException.class.getName().equals(exceptionClassName)) {
    // 最终会抛给异常处理器
    throw new XXXException("用户名不存在");
   } else if (IncorrectCredentialsException.class.getName().equals(exceptionClassName)) {
    throw new XXXException("用户名/密码错误");
   } else {
    throw new Exception();// 最终在异常处理器生成未知错误
   }
  }
  // 如果登录成功的话不走此方法，shiro认证成功会自动跳转到上一个请求路径，配的的successUrl没效果，后边会说
  // 登陆失败走此方法，捕获异常，然后 return ~ ,还到login页面
  return "login.jsp";
 }
}

3、检测权限 controller

 //此方法为了验证权限是否生效
 @RequestMapping("/findAll.do")
 @RequiresPermissions("admin:ee")
 public ModelAndView list(HttpServletRequest request){
  .......
 }

三、常见问题

因为有一些特别常见的问题，需要修改xml配置，所以现在先手问题，把xml配置放在后边，直接就配置完善好的xml

问题一：登陆成功后shiro默认跳到上一次请求，没有上一次请求默认跳到/  ，那我们就想控制调到自己定义的路径咋办呢？

解决方案：

步骤一：继承FormAuthenticationFilter类，重写onLoginSuccess方法，这里可以自定义路径，因为这里自定义了成功跳转的路径，所以配置里的successUrl不用配置，赔了也没效果。。

public class LoginSuccessToFilter extends FormAuthenticationFilter {
 @Override
 protected boolean onLoginSuccess(AuthenticationToken token, Subject subject, ServletRequest request, ServletResponse response) throws Exception {
  WebUtils.getAndClearSavedRequest(request);
  WebUtils.redirectToSavedRequest(request,response,"/findAll.do");
  return false;
 }
}

步骤二：

在shiro的xml配置文件中配置

 <bean id="myfilter" class="com.xxx.realm.LoginSuccessToFilter"></bean>

在 shiroFilter配置中引入,完整xml在后边

<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
  <property name="filters">
   <map>
    <entry key="authc" value-ref="myfilter"></entry>
   </map>
  </property>
</bean>
<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
  <property name="filters">
   <map>
    <entry key="authc" value-ref="myfilter"></entry>
   </map>
  </property>
</bean>

四、Xml配置

applicationContext-shiro.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

springmvc的配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:aop="http://www.springframework.org/schema/aop"

 <mvc:annotation-driven></mvc:annotation-driven>
 <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"></bean>
 <!-- 开启shiro注解的配置移动到这儿 -->
 <bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator" depends-on="lifecycleBeanPostProcessor">
