srpingboot整合shiro簡單應用

引言:推薦一篇博客https://blog.csdn.net/qq_41737716/article/details/82948729，我下邊寫得只是簡單的應用

一、添加pom依賴

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

二、創建shiro的配置類

package com.sunlands.recruit.admin.config;

import com.sunlands.recruit.admin.oauth2.OAuth2Filter;
import com.sunlands.recruit.admin.oauth2.OAuth2Realm;
import org.apache.shiro.mgt.SecurityManager;
import org.apache.shiro.session.mgt.SessionManager;
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.web.session.mgt.DefaultWebSessionManager;
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("sessionManager")
    public SessionManager sessionManager() {
        DefaultWebSessionManager sessionManager = new DefaultWebSessionManager();
        sessionManager.setSessionValidationSchedulerEnabled(true);
        sessionManager.setSessionIdCookieEnabled(true);
        return sessionManager;
    }

    @Bean("securityManager")
    public SecurityManager securityManager(OAuth2Realm oAuth2Realm, SessionManager sessionManager) {
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        securityManager.setRealm(oAuth2Realm);
        securityManager.setSessionManager(sessionManager);

        return securityManager;
    }

    @Bean("shiroFilter")
    public ShiroFilterFactoryBean shirFilter(SecurityManager securityManager) {
        ShiroFilterFactoryBean shiroFilter = new ShiroFilterFactoryBean();
        shiroFilter.setSecurityManager(securityManager);
        //oauth過濾
        Map<String, Filter> filters = new HashMap<>();
        filters.put("oauth2", new OAuth2Filter());
        shiroFilter.setFilters(filters);

        Map<String, String> filterMap = new LinkedHashMap<>();
        filterMap.put("/webjars/**", "anon");
        filterMap.put("/druid/**", "anon");
        filterMap.put("/app/**", "anon");
        filterMap.put("/sys/login", "anon");
        filterMap.put("/token", "anon");
        filterMap.put("/swagger/**", "anon");
        filterMap.put("/v2/api-docs", "anon");
        filterMap.put("/swagger-ui.html", "anon");
        filterMap.put("/swagger-resources/**", "anon");
        filterMap.put("/captcha.jpg", "anon");
        filterMap.put("/orderApply/approveNotifyCallback", "anon");
        filterMap.put("/**", "oauth2");
        shiroFilter.setFilterChainDefinitionMap(filterMap);

        return shiroFilter;
    }

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

    @Bean
    public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() {
        DefaultAdvisorAutoProxyCreator proxyCreator = new DefaultAdvisorAutoProxyCreator();
        proxyCreator.setProxyTargetClass(true);
        return proxyCreator;
    }

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

}

三、創建Realm，用來授權和認證

package com.sunlands.recruit.admin.oauth2;

import com.sunlands.recruit.admin.entity.SysUserEntity;
import com.sunlands.recruit.admin.entity.SysUserTokenEntity;
import com.sunlands.recruit.admin.service.ShiroService;
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 org.springframework.stereotype.Component;

import java.util.Set;

@Component
public class OAuth2Realm extends AuthorizingRealm {

    @Autowired
    private ShiroService shiroService;

    @Override
    public boolean supports(AuthenticationToken token) {
        return token instanceof OAuth2Token;
    }

    /**
     * 授權(驗證權限時調用)
     */
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        SysUserEntity user = (SysUserEntity) principals.getPrimaryPrincipal();
        Long userId = user.getUserId();

        //用戶權限列表
        Set<String> permsSet = shiroService.getUserPermissions(userId);

        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
        info.setStringPermissions(permsSet);
        return info;
    }

    /**
     * 認證(登錄時調用)
     */
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        String accessToken = (String) token.getPrincipal();

        //根據accessToken，查詢用戶信息
        SysUserTokenEntity tokenEntity = shiroService.queryByToken(accessToken);
        //token失效
        if (tokenEntity == null || Long.valueOf(tokenEntity.getExpireTime().getTime()) < System.currentTimeMillis()) {
            throw new IncorrectCredentialsException("token失效");
        }
        //查詢用戶信息
        SysUserEntity user = shiroService.queryUser(tokenEntity.getUserId());
        //賬號鎖定
        if (user.getStatus() == 0) {
            throw new LockedAccountException("賬號已被鎖定,請聯繫管理員");
        }

        SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(user, accessToken, getName());
        return info;
    }
}

四、出現異常需要攔截，配置攔截器處理驗證登錄等問題

package com.sunlands.recruit.admin.exception;

import com.sunlands.recruit.common.utils.R;
import org.apache.shiro.authz.UnauthorizedException;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.RestControllerAdvice;


@RestControllerAdvice
public class ShiroExceptionHandler {

    private Logger logger = LoggerFactory.getLogger(getClass());

    @ExceptionHandler(UnauthorizedException.class)
    public R handleNotHavePermission(UnauthorizedException e) {
        logger.error(e.getMessage(), e);
        return R.error(5555, "您無權訪問");
    }
}
