项目结构

spring+shiro+springmvc+maven权限卡控示例

UserController , 主要负责用户登入和注销。

LinewellController, 主要负责请求受权限卡控的数据。

MyRealm，自定义realm。

Authorization，主要是权限过滤器。

UserController

package com.linewell.controller;

import com.alibaba.fastjson.JSON;

import org.apache.shiro.SecurityUtils;

import org.apache.shiro.authc.UsernamePasswordToken;

import org.apache.shiro.subject.Subject;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.ResponseBody;

import java.util.HashMap;

import java.util.Map;

@Controller

@RequestMapping("/user")

public class UserController {

    /**

     * 用户登录

     */

    @RequestMapping("/login")

    @ResponseBody

    public String login(String username, String password) {

        Map<String, Object> result = new HashMap<>();

        UsernamePasswordToken usernamePasswordToken = new UsernamePasswordToken(username, password);

        Subject subject = SecurityUtils.getSubject();

        subject.login(usernamePasswordToken);

        result.put("success", true);

        return JSON.toJSONString(result);

    }

    /**

     * 注销登录

     */

    @RequestMapping("/logout")

    public String logout() {

        Map<String, Object> result = new HashMap<>();

        SecurityUtils.getSubject().logout();

        result.put("success", true);

        return JSON.toJSONString(result);

    }

}

LinewellController：

package com.linewell.controller;

import com.alibaba.fastjson.JSONObject;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.ResponseBody;

import java.util.HashMap;

import java.util.Map;

@Controller

@RequestMapping("/linewell")

public class LinewellController {

    @RequestMapping("/getData")

    @ResponseBody

    public String getData() {

        Map<String, Object> result = new HashMap<>();

        result.put("data", "you have put data to result");

        return JSONObject.toJSONString(result);

    }

}

MyRealm:

package com.linewell.system;

import org.apache.shiro.authc.*;

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 java.util.HashSet;

import java.util.Set;

public class MyRealm extends AuthorizingRealm {

    public String getName(){

        return "myRealm";

    }

    @Override

    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {

        SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo();

        Set<String> set = new HashSet<>();

        set.add("admin");

        set.add("user");

        simpleAuthorizationInfo.setRoles(set);

        Set<String> permissions = new HashSet<>();

        permissions.add("/linewell/getData");

        System.out.println(permissions);

        simpleAuthorizationInfo.setStringPermissions(permissions);

        return simpleAuthorizationInfo;

    }

    @Override

    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {

        UsernamePasswordToken usernamePasswordToken = (UsernamePasswordToken) token;

        String principal = String.valueOf(usernamePasswordToken.getPrincipal());

        String credential = String.valueOf(usernamePasswordToken.getPassword());

        if (principal.equals("admin") && credential.equals("123123")) {

        } else {

            throw new AuthenticationException("账号或者密码错误");

        }

        SimpleAuthenticationInfo simpleAuthenticationInfo = new SimpleAuthenticationInfo(token.getPrincipal(), token.getCredentials(), getName());

        return simpleAuthenticationInfo;

    }

    @Override

    public void clearCachedAuthorizationInfo(PrincipalCollection principals) {

        super.clearCachedAuthorizationInfo(principals);

    }

    @Override

    public void clearCachedAuthenticationInfo(PrincipalCollection principals) {

        super.clearCachedAuthenticationInfo(principals);

    }

    @Override

    public void clearCache(PrincipalCollection principals) {

        super.clearCache(principals);

    }

    public void clearAllCachedAuthorizationInfo() {

        getAuthorizationCache().clear();

    }

    public void clearAllCachedAuthenticationInfo() {

        getAuthenticationCache().clear();

    }

}

Authorization:

package com.linewell.system;

import org.apache.shiro.SecurityUtils;

import org.apache.shiro.subject.Subject;

import org.apache.shiro.web.filter.authz.AuthorizationFilter;

import javax.servlet.ServletRequest;

import javax.servlet.ServletResponse;

import javax.servlet.http.HttpServletRequest;

public class Authorization extends AuthorizationFilter {

    @Override

    protected boolean isAccessAllowed(ServletRequest servletRequest, ServletResponse servletResponse, Object o) throws Exception {

        HttpServletRequest req = (HttpServletRequest) servletRequest;

        Subject subject = SecurityUtils.getSubject();

        if (!subject.isAuthenticated()) {

            return false;

        }

        String effectivePath = req.getRequestURI().substring(req.getContextPath().length());

        System.out.println(effectivePath);

        if (subject.isPermitted(effectivePath)) {

            return true;

        } else {

            return false;

        }

    }

}
