spring+shiro 整合實例代碼詳解
一、添加相關依賴
<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、編寫代碼
1、自定義realm
public class CommonRealm extends AuthorizingRealm {
@Autowired
private UserLoginService userLoginService;
@Override
public String getName() {
return "CommonRealm";
}
//授權
@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;
}
//身份認證
@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 {
// 如果登陸失敗從request中獲取異常信息,shiroLoginFailure就是shiro異常類的全限定名
String exceptionClassName = (String) request.getAttribute("shiroLoginFailure");
if (exceptionClassName != null) {
if (UnknownAccountException.class.getName().equals(exceptionClassName)) {
// 最終會拋給異常處理器
throw new XXXException("用戶名不存在");
} else if (IncorrectCredentialsException.class.getName().equals(exceptionClassName)) {
throw new XXXException("用戶名/密碼錯誤");
} else {
throw new Exception();// 最終在異常處理器生成未知錯誤
}
}
// 如果登錄成功的話不走此方法,shiro認證成功會自動跳轉到上一個請求路徑,配的的successUrl沒效果,后邊會說
// 登陸失敗走此方法,捕獲異常,然后 return ~ ,還到login頁面
return "login.jsp";
}
}
3、檢測權限 controller
//此方法為了驗證權限是否生效
@RequestMapping("/findAll.do")
@RequiresPermissions("admin:ee")
public ModelAndView list(HttpServletRequest request){
.......
}
三、常見問題
因為有一些特別常見的問題,需要修改xml配置,所以現(xiàn)在先手問題,把xml配置放在后邊,直接就配置完善好的xml
問題一:登陸成功后shiro默認跳到上一次請求,沒有上一次請求默認跳到/ ,那我們就想控制調到自己定義的路徑咋辦呢?
解決方案:
步驟一:繼承FormAuthenticationFilter類,重寫onLoginSuccess方法,這里可以自定義路徑,因為這里自定義了成功跳轉的路徑,所以配置里的successUrl不用配置,賠了也沒效果。。
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;
}
}
步驟二:
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在后邊
<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"?>

<!-- 攔截到,跳轉到的地址,通過此地址去認證 -->

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" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:jdbc="http://www.springframework.org/schema/jdbc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc.xsd"> <context:component-scan base-package="com.dhl.controller"></context:component-scan> <mvc:annotation-driven></mvc:annotation-driven> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"></bean> <!-- 開啟shiro注解的配置移動到這兒 --> <bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator" depends-on="lifecycleBeanPostProcessor"> <property name="proxyTargetClass" value="true" /> </bean> <bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor"> <property name="securityManager" ref="securityManager"/> </bean> </beans>
