基于Spring框架的Shiro配置方法
投稿：mdxy-dxy
这篇文章主要介绍了基于Spring框架的Shiro配置方法,需要的朋友可以参考下
一、在web.xml中添加shiro过滤器
<!-- Shiro filter--> <filter> <filter-name>shiroFilter</filter-name> <filter-class> org.springframework.web.filter.DelegatingFilterProxy </filter-class> </filter> <filter-mapping> <filter-name>shiroFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
二、在Spring的applicationContext.xml中添加shiro配置
1、添加shiroFilter定义
<!-- Shiro Filter --> <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean"> <property name="securityManager" ref="securityManager" /> <property name="loginUrl" value="/login" /> <property name="successUrl" value="/user/list" /> <property name="unauthorizedUrl" value="/login" /> <property name="filterChainDefinitions"> <value> /login = anon /user/** = authc /role/edit/* = perms[role:edit] /role/save = perms[role:edit] /role/list = perms[role:view] /** = authc </value> </property> </bean>
2、添加securityManager定义
复制代码 代码如下:
<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
<property name="realm" ref="myRealm" />
</bean>
3、添加realm定义
复制代码 代码如下:
<bean id=" myRealm" class="com...MyRealm" />
三、实现MyRealm：继承AuthorizingRealm，并重写认证授权方法
public class MyRealm extends AuthorizingRealm{
private AccountManager accountManager;
public void setAccountManager(AccountManager accountManager) {
this.accountManager = accountManager;
}
/**
* 授权信息
*/
protected AuthorizationInfo doGetAuthorizationInfo(
PrincipalCollection principals) {
String username=(String)principals.fromRealm(getName()).iterator().next();
if( username != null ){
User user = accountManager.get( username );
if( user != null && user.getRoles() != null ){
SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
for( SecurityRole each: user.getRoles() ){
info.addRole(each.getName());
info.addStringPermissions(each.getPermissionsAsString());
}
return info;
}
}
return null;
}
/**
* 认证信息
*/
protected AuthenticationInfo doGetAuthenticationInfo(
AuthenticationToken authcToken ) throws AuthenticationException {
UsernamePasswordToken token = (UsernamePasswordToken) authcToken;
String userName = token.getUsername();
if( userName != null && !"".equals(userName) ){
User user = accountManager.login(token.getUsername(),
String.valueOf(token.getPassword()));
if( user != null )
return new SimpleAuthenticationInfo(
user.getLoginName(),user.getPassword(), getName());
}
return null;
}
}
