基于Spring框架的Shiro配置

一、在web.xml中添加shiro过滤器 

1. <!-- Shiro filter-->
2. <filter>
3. <filter-name>shiroFilter</filter-name>
4. <filter-class>
5. org.springframework.web.filter.DelegatingFilterProxy
6. </filter-class>
7. </filter>
8. <filter-mapping>
9. <filter-name>shiroFilter</filter-name>
10. <url-pattern>/*</url-pattern>
11. </filter-mapping>

二、在Spring的applicationContext.xml中添加shiro配置 
1、添加shiroFilter定义 

1. <!-- Shiro Filter -->
2. <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
3. <property name="securityManager" ref="securityManager" />
4. <property name="loginUrl" value="/login" />
5. <property name="successUrl" value="/user/list" />
6. <property name="unauthorizedUrl" value="/login" />
7. <property name="filterChainDefinitions">
8. <value>
9. /login = anon
10. /user/** = authc
11. /role/edit/* = perms[role:edit]
12. /role/save = perms[role:edit]
13. /role/list = perms[role:view]
14. /** = authc
15. </value>
16. </property>
17. </bean>

2、添加securityManager定义 

1. <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
2. <property name="realm" ref="myRealm" />
3. </bean>

3、添加realm定义 

1. <bean id=" myRealm" class="com...MyRealm" />

三、实现MyRealm：继承AuthorizingRealm，并重写认证授权方法 

1. public class MyRealm extends AuthorizingRealm{
2. private AccountManager accountManager;
3. public void setAccountManager(AccountManager accountManager) {
4. this.accountManager = accountManager;
5. }
6. /**
7. * 授权信息
8. */
9. protected AuthorizationInfo doGetAuthorizationInfo(
10. PrincipalCollection principals) {
11. String username=(String)principals.fromRealm(getName()).iterator().next();
12. if( username != null ){
13. User user = accountManager.get( username );
14. if( user != null && user.getRoles() != null ){
15. SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
16. for( SecurityRole each: user.getRoles() ){
17. info.addRole(each.getName());
18. info.addStringPermissions(each.getPermissionsAsString());
19. }
20. return info;
21. }
22. }
23. return null;
24. }
25. /**
26. * 认证信息
27. */
28. protected AuthenticationInfo doGetAuthenticationInfo(
29. AuthenticationToken authcToken ) throws AuthenticationException {
30. UsernamePasswordToken token = (UsernamePasswordToken) authcToken;
31. String userName = token.getUsername();
32. if( userName != null && !"".equals(userName) ){
33. User user = accountManager.login(token.getUsername(),
34. String.valueOf(token.getPassword()));
35. if( user != null )
36. return new SimpleAuthenticationInfo(
37. user.getLoginName(),user.getPassword(), getName());
38. }
39. return null;
40. }
41. }
