1.配置 pom

<shiro.version>1.4.0</shiro.version>
    
           
    	    <dependency>
    	      <groupId>org.apache.shiro</groupId>
    	      <artifactId>shiro-core</artifactId>
    	      <version>${shiro.version}</version>
    	    </dependency>
    	    <dependency>
    	      <groupId>org.apache.shiro</groupId>
    	      <artifactId>shiro-web</artifactId>
    	      <version>${shiro.version}</version>
    	    </dependency>
    	    <dependency>
    	      <groupId>org.apache.shiro</groupId>
    	      <artifactId>shiro-ehcache</artifactId>
    	      <version>${shiro.version}</version>
    	    </dependency>
    	    <dependency>
    	      <groupId>org.apache.shiro</groupId>
    	      <artifactId>shiro-spring</artifactId>
    	      <version>${shiro.version}</version>
    	    </dependency>

2. MyShiroRealm.java

package org.fh.realm;
    
    import java.util.Collection;
    import java.util.HashSet;
    
    import org.apache.shiro.authc.*;

    import org.apache.shiro.subject.PrincipalCollection;
    import org.fh.service.system.UsersService;
    import org.fh.util.Const;
    import org.fh.util.Jurisdiction;
    import org.fh.entity.PageData;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.context.annotation.Lazy;
     
    /**
     * 说明：Shiro身份认证

     * From：www.fhadmin.org
     */
    public class MyShiroRealm extends AuthorizingRealm {
     
        @Autowired
        @Lazy
        private UsersService usersService;
        /**
         * 登录认证
         */
        @Override
        protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
            UsernamePasswordToken token = (UsernamePasswordToken)authenticationToken; 	//UsernamePasswordToken用于存放提交的登录信息
    	    PageData pd = new PageData();
    	    pd.put("USERNAME", token.getUsername());
    			try {
    				pd = usersService.findByUsername(pd);
    				if (pd != null){
    				    return new SimpleAuthenticationInfo(pd.getString("USERNAME"), pd.getString("PASSWORD"), getName());
    		        }
    			} catch (Exception e) {
    				return null;
    			}
    		return null;
        }
    	@Override
    	protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
    		String USERNAME = (String) super.getAvailablePrincipal(principals);
    		SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
    		Session session = Jurisdiction.getSession();
    		Collection<String> shiroSet= new HashSet<String>();
    		shiroSet = (Collection<String>)session.getAttribute(USERNAME + Const.SHIROSET);
    		if(null != shiroSet){
    			info.addStringPermissions(shiroSet);
    			return info;
    		}else {
    			return null;
    		}
    	}
    
    }
