基于Spring框架的Shiro配置

2024-02-23 14:58:28

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. }
