Springmvc+Shiro+zTree 实战（三）：spring整合shiro

推荐shiro教程：https://www.w3cschool.cn/shiro/

 

Spring整合shiro步骤解读：

一：导入shiro相关依赖

二：web.xml中配置shiro过滤器

三：编写自定义的DbRealm，进行认证和授权

四：spring整合shiro配置文件：applicationContext-shiro.xml

五：shiro缓存文件：ehcache-shiro.xml

六：spring容器配置加载applicationContext-shiro.xml文件

 

一：导入shiro相关依赖

	org.apache.shiro
	shiro-core
	1.4.0


	org.apache.shiro
	shiro-ehcache
	1.4.0


	org.apache.shiro
	shiro-web
	1.4.0


	org.apache.shiro
	shiro-spring
	1.4.0

二：web.xml中配置shiroFilter

	shiroFilter
	org.springframework.web.filter.DelegatingFilterProxy


	shiroFilter
	/*

 

三：编写自定义的DbRealm，实现用户的认证和授权

import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.springframework.beans.factory.annotation.Autowired;

import com.mote.pojo.Role;
import com.mote.pojo.User;
import com.mote.service.RoleService;
import com.mote.service.UserService;

public class ShiroDbRealm extends AuthorizingRealm {

	@Autowired
	private UserService userService;
	@Autowired
	private RoleService roleService;

	/**
	 * 认证
	 */
	protected AuthenticationInfo doGetAuthenticationInfo(
			AuthenticationToken authcToken) throws AuthenticationException {

		UsernamePasswordToken token = (UsernamePasswordToken) authcToken;//转为UsernamePasswordToken
		
		String userName = token.getUsername();//获取用户名
		String password = new String(token.getPassword());//获取密码
		
		User user = userService.getUserByNamePwd(userName, password);//通過用户名和密码获取用户
		if (user == null)
			return null;

		// 身份认证验证成功，返回一个AuthenticationInfo实现
		return new SimpleAuthenticationInfo(user.getUserName(),
				password, getName());

	}

	/**
	 * 授权
	 */
	protected AuthorizationInfo doGetAuthorizationInfo(
			PrincipalCollection principals) {

		SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();

		String userName = (String) getAvailablePrincipal(principals); // 获取用户名

		Role role = roleService.getRolesByUserName(userName);// 获取用户角色

		if (role == null)
			return null;

		info.addRole(role.getRoleName()); // 添加角色

		List perms = roleService.getPerm(role.getId());// 获取角色对应的权限
		info.addStringPermissions(perms); // 添加权限

		return info;
	}

}

 

对应的sql语句：

	SELECT * FROM user WHERE user_name = #{userName} AND password = #{password}



	SELECT r.id,r.role_name FROM `user` u JOIN role r
	ON u.role_id = r.id AND u.user_name = #{userName}



	SELECT perm_token FROM permission WHERE id IN
	(SELECT p.perm_id FROM role_permission p 
    WHERE p.role_id = #{id})

四：创建spring整合shiro的配置文件：applicationContext-shiro.xml

	
	

	
	
		
	

	
	
		
		
	

	
	
		
		
	

	
	
		
		
		
		
		
		
		
		
			
		
		
			
			
				/css/** = anon
				/img/** = anon
				/js/** = anon
				/login = anon
				/loginOut = logout  
				/**/**=user
			
		
	


	
	

	
	
		
	
	
	
		
	

关于权限管理filterChainDefinitions过滤器配置可以参考：filterChainDefinitions配置

 

五：创建ehcache缓存文件：shiro-ehcache.xml

六：spring容器加载applicationContext-shiro.xml文件

    contextConfigLocation
    classpath:applicationContext*.xml
