springboot+shiro+jwt

shiro和jwt不明白的查看其他文档，本人不在这里赘述！！

 

1.引用 shiro和jwt

在pom.xml文件中添加引用

<!--整合Shiro安全框架-->
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-spring</artifactId>
            <version>1.3.2</version>
        </dependency>
        <!--集成jwt实现toke-->
        <dependency>
            <groupId>com.auth0</groupId>
            <artifactId>java-jwt</artifactId>
            <version>3.18.1</version>
        </dependency>

2.添加shiro配置类

package com.ckfuture.pro.config;

import com.ckfuture.pro.shiro.CustomRealm;
import com.ckfuture.pro.shiro.JWTFilter;
import org.apache.shiro.mgt.DefaultSessionStorageEvaluator;
import org.apache.shiro.mgt.DefaultSubjectDAO;
import org.apache.shiro.spring.LifecycleBeanPostProcessor;
import org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.apache.shiro.mgt.SecurityManager;
import org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import javax.servlet.Filter;
import java.util.HashMap;
import java.util.LinkedHashMap;
import java.util.Map;

@Configuration
public class ShiroConfig {
    /**

    @Bean

        // 添加自己的过滤器并且取名为jwt
        Map<String, Filter> filterMap = new LinkedHashMap<>();
        //设置我们自定义的JWT过滤器
        filterMap.put("jwt", new JWTFilter());
        factoryBean.setFilters(filterMap);
        factoryBean.setSecurityManager(securityManager);
        // 设置无权限时跳转的 url;
        factoryBean.setUnauthorizedUrl("/unauthorized/无权限");
        Map<String, String> filterRuleMap = new HashMap<>();
        // 所有请求通过我们自己的JWT Filter
        filterRuleMap.put("/**", "jwt");
        // 放行不需要权限认证的接口
        //放行Swagger接口
        filterRuleMap.put("/v2/api-docs","anon");

        filterRuleMap.put("/swagger-ui.html","anon");
        filterRuleMap.put("/webjars/**","anon");
        //放行登录接口和其他不需要权限的接口
        filterRuleMap.put("/sys/userinfo/login", "anon");
        filterRuleMap.put("/unauthorized/**", "anon");

        factoryBean.setFilterChainDefinitionMap(filterRuleMap);
        return factoryBean;

    }

    /**
     * 注入 securityManager
     */
    @Bean
    public SecurityManager securityManager(CustomRealm customRealm) {
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        // 设置自定义 realm.
        securityManager.setRealm(customRealm);

        /*
         * 关闭shiro自带的session
         */
        DefaultSubjectDAO subjectDAO = new DefaultSubjectDAO();
        DefaultSessionStorageEvaluator defaultSessionStorageEvaluator = new DefaultSessionStorageEvaluator();
        defaultSessionStorageEvaluator.setSessionStorageEnabled(false);
        subjectDAO.setSessionStorageEvaluator(defaultSessionStorageEvaluator);
        securityManager.setSubjectDAO(subjectDAO);
        return securityManager;
    }

    /**
     * 添加注解支持
     */
    @Bean
    public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() {
        DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator = new DefaultAdvisorAutoProxyCreator();
        // 强制使用cglib，防止重复代理和可能引起代理出错的问题
        defaultAdvisorAutoProxyCreator.setProxyTargetClass(true);
        return defaultAdvisorAutoProxyCreator;
    }

    @Bean
    public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(SecurityManager securityManager) {
        AuthorizationAttributeSourceAdvisor advisor = new AuthorizationAttributeSourceAdvisor();
        advisor.setSecurityManager(securityManager);
        return advisor;
    }

    @Bean
    public LifecycleBeanPostProcessor lifecycleBeanPostProcessor() {
        return new LifecycleBeanPostProcessor();
    }

}

3.自定义过滤器，对token进行处理

package com.ckfuture.pro.shiro;

import com.ckfuture.pro.shiro.JWTToken;

    @Override

            }
        }

        return true;
    }

            return false;
        }
        return super.preHandle(request, response);
    }

    /**
     * 将非法请求跳转到 /unauthorized/**
     */
    private void responseError(ServletResponse response, String message) {
        try {

4.TOKEN扩展类

package com.ckfuture.pro.shiro;

import org.apache.shiro.authc.AuthenticationToken;

    private String token;

    public JWTToken(String token) {
        this.token = token;
    }

    @Override
    public Object getPrincipal() {
        return token;
    }

    @Override
    public Object getCredentials() {
        return token;
    }

}

5.JWT工具类

6.自定义Realm,实现Shiro安全认证

package com.ckfuture.pro.shiro;

import com.ckfuture.pro.shiro.JWTToken;
import com.ckfuture.pro.shiro.JWTUtil;
import com.ckfuture.pro.sys.userinfo.service.userinfoService;
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.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 org.springframework.stereotype.Component;
/**

 * @version： v1.0
 * @LastEditTime：
 * @LastEditors：
 * @copyright： hrbckfuture.com
 */
@Component
public class CustomRealm extends AuthorizingRealm {

    @Autowired
    private userinfoService userService;//用户信息接口

    /**
     * 必须重写此方法，不然会报错
     */
    @Override
    public boolean supports(AuthenticationToken token) {
        return token instanceof JWTToken;
    }

    /**
     * 默认使用此方法进行用户信息正确与否验证，错误抛出异常即可。
     * 自定义后续方法
     */
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        String token = (String) authenticationToken.getCredentials();
        // 解密获得userId，用于和数据库进行对比
        String userId = JWTUtil.getUserId(token);

        if (userId == null || !JWTUtil.verify(token, userId)) {
            throw new AuthenticationException("token认证失败！");
        }

        /* 以下数据库查询可根据实际情况，可以不必再次查询，这里我两次查询会很耗资源
         * 具体业务判断
         */


//        String password = userService.getPassword(username);
//        if (password == null) {
//            throw new AuthenticationException("该用户不存在！");
//        }
//        int ban = userService.checkUserBanStatus(username);
//        if (ban == 1) {
//            throw new AuthenticationException("该用户已被封号！");
//        }
        return new SimpleAuthenticationInfo(token, token, "MyRealm");
    }

    /**
     * 只有当需要检测用户权限的时候才会调用此方法，例如checkRole,checkPermission之类的
     */
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        System.out.println("————权限认证————");
        String userId = JWTUtil.getUserId(principals.toString());
        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
        //获得该用户角色
        //String role = userService.getRole(username);
        //每个角色拥有默认的权限
       // String rolePermission = userService.getRolePermission(username);
        //每个用户可以设置新的权限
      //  String permission = userService.getPermission(username);
       // Set<String> roleSet = new HashSet<>();
       // Set<String> permissionSet = new HashSet<>();
        //需要将 role, permission 封装到 Set 作为 info.setRoles(), info.setStringPermissions() 的参数
      //  roleSet.add(role);
      //  permissionSet.add(rolePermission);
      //  permissionSet.add(permission);
        //设置该用户拥有的角色和权限
      //  info.setRoles(roleSet);
       // info.setStringPermissions(permissionSet);
        return info;
    }

}

7.获取token签名

在用户登录接口中返回token

  @ApiOperation(value = "用户登录",httpMethod = "GET", notes = "获取用户登录信息")
    @ResponseBody
    @RequestMapping(value = {"/login"}, method = RequestMethod.GET)
    public Result login(
            @ApiParam(value = "登录账号", required = true) String jobNO
            ,@ApiParam(value = "登录密码", required = true) String upassword) {
        try {
            //返回用户实体
            entity = service.getOneByJobNOandPassWord(jobNO, upassword);

            //生成签名
            String userId=entity.getId().toString();
            String user_token=  JWTUtil.createToken(userId);

            //返回token
            entity.setToken(user_token);

            return Result.success(entity);
        } catch (Exception e) {
            System.out.println(e.getMessage());
            return Result.failure(ResponseCode.ERROR_999, ResponseMsg.QUERY_ERROR);
        }
    }

其他接口正常写就可以，在过滤器中就有token和权限的验证。

 

 其他请求头中携带 token
