shiro中怎么利用springboot实现前后端分离

shiro中怎么利用springboot实现前后端分离，针对这个问题，这篇文章详细介绍了相对应的分析和解答，希望可以帮助更多想解决这个问题的小伙伴找到更简单易行的方法。

1、shiro整合springboot的配置

package com.hisi.config; import java.util.LinkedHashMap;import java.util.Map; import javax.servlet.Filter; import org.apache.shiro.session.mgt.eis.MemorySessionDAO;import org.apache.shiro.session.mgt.eis.SessionDAO;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 org.springframework.context.annotation.DependsOn; import com.hisi.shiro.LoginAuthorizationFilter;import com.hisi.shiro.RestFilter;import com.hisi.shiro.UserRealm; /** * shiro权限管理的配置 * @author xuguoqin * @date 2018年5月4日 * @version 1.0 */@Configurationpublic class ShiroConfig {  /** * 安全管理器 * @param realm * @return */ @Bean public DefaultWebSecurityManager securityManager(){ DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager(); securityManager.setRealm(userRealm()); securityManager.setSessionManager(sessionManager()); return securityManager; }  /** * Realm配置 * @return */ @Bean public UserRealm userRealm(){ return new UserRealm(); }  /** * SessionDAO配置 * @return */ @Bean public SessionDAO sessionDAO(){ return new MemorySessionDAO(); }  /** * sessionManager配置 * @param sessionDAO * @return */ @Bean public DefaultWebSessionManager sessionManager(){ DefaultWebSessionManager sessionManager = new DefaultWebSessionManager(); sessionManager.setSessionDAO(sessionDAO()); return sessionManager; }  /** * shiroFilter配置 * @param securityManager * @return */ @Bean public ShiroFilterFactoryBean shiroFilterFactoryBean(DefaultWebSecurityManager securityManager){  ShiroFilterFactoryBean shiroFilter = new ShiroFilterFactoryBean(); shiroFilter.setSecurityManager(securityManager()); Map<String, Filter> filters = new LinkedHashMap<String, Filter>(); filters.put("token", new LoginAuthorizationFilter()); filters.put("corsFilter", new RestFilter()); shiroFilter.setFilters(filters); Map<String, String> filterChainDefinitionMap = new LinkedHashMap<String, String>(); filterChainDefinitionMap.put("/user/login", "corsFilter,anon"); filterChainDefinitionMap.put("/user/logout", "corsFilter,anon"); filterChainDefinitionMap.put("/user/**", "corsFilter,token"); shiroFilter.setFilterChainDefinitionMap(filterChainDefinitionMap); return shiroFilter; }  /**   * 保证实现了Shiro内部lifecycle函数的bean执行   */  @Bean  public LifecycleBeanPostProcessor lifecycleBeanPostProcessor() {    return new LifecycleBeanPostProcessor();  }   /**   * 启用shrio授权注解拦截方式，AOP式方法级权限检查   */  @Bean  @DependsOn(value = "lifecycleBeanPostProcessor") //依赖其他bean的初始化  public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() {    return new DefaultAdvisorAutoProxyCreator();  }  /** * 加入注解的使用，不加入这个注解不生效 使用shiro框架提供的切面类，用于创建代理对象  * @param securityManager * @return */  @Bean  public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(DefaultWebSecurityManager securityManager) {    AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor();    authorizationAttributeSourceAdvisor.setSecurityManager(securityManager);    return authorizationAttributeSourceAdvisor;  }    }

2、这里配置的两个过滤器RestFilter和LoginAuthorizationFilter，RestFilter是用于解决前后端分离时的跨域问题，服务端在响应头设置可以接受的请求参数

package com.hisi.shiro; import java.io.IOException;import java.util.Optional; import javax.servlet.Filter;import javax.servlet.FilterChain;import javax.servlet.FilterConfig;import javax.servlet.ServletException;import javax.servlet.ServletRequest;import javax.servlet.ServletResponse;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse; /** * 前后端分离RESTful接口过滤器 *  * @author xuguoqin * */public class RestFilter implements Filter {  @Override public void init(FilterConfig filterConfig) throws ServletException {  }  @Override public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)  throws IOException, ServletException { HttpServletRequest req = null; if (request instanceof HttpServletRequest) {  req = (HttpServletRequest) request; } HttpServletResponse res = null; if (response instanceof HttpServletResponse) {  res = (HttpServletResponse) response; } if (req != null && res != null) {  //设置允许传递的参数  res.setHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept, Authorization");  //设置允许带上cookie  res.setHeader("Access-Control-Allow-Credentials", "true");  String origin = Optional.ofNullable(req.getHeader("Origin")).orElse(req.getHeader("Referer"));  //设置允许的请求来源  res.setHeader("Access-Control-Allow-Origin", origin);  //设置允许的请求方法  res.setHeader("Access-Control-Allow-Methods", "GET, POST, PATCH, PUT, DELETE, OPTIONS"); } chain.doFilter(request, response); }  @Override public void destroy() {  } }

前者ajax请求的时候应该带上参数

$.ajax({type: "GET",url: url,xhrFields: {  withCredentials: true // 携带跨域cookie},processData: false,success: function(data) {  console.log(data); }});

3、LoginAuthorizationFilter主要是对未登录的用户进行过滤然后返回json数据给前端，之前遇到的问题就是shiro配置的loginUrl会导致出现302的问题，在前后端分离的项目中，页面的跳转应该由前端来进行控制，这里前端使用的是vue框架，我需要对shiro中未登录的过滤器FormAuthenticationFilter进行重构

package com.hisi.shiro; import java.io.IOException;import java.io.PrintWriter;import java.util.Set; import javax.servlet.ServletRequest;import javax.servlet.ServletResponse;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse; import org.apache.shiro.SecurityUtils;import org.apache.shiro.authc.AuthenticationToken;import org.apache.shiro.subject.Subject;import org.apache.shiro.util.CollectionUtils;import org.apache.shiro.web.filter.authc.FormAuthenticationFilter;import org.apache.shiro.web.filter.authz.AuthorizationFilter;import org.apache.shiro.web.filter.authz.PermissionsAuthorizationFilter;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.beans.factory.annotation.Autowired; import com.alibaba.fastjson.JSONObject;import com.commons.model.YfpjResult;import com.hisi.mapper.HisiUserMapper;import com.hisi.model.HisiUser;import com.hisi.util.Constant;import com.hisi.util.UserAuthStatusEnum; /** * shiro未登录反回状态码 * @author xuguoqin * @date 2018年5月10日 * @version 1.0 */public class LoginAuthorizationFilter extends FormAuthenticationFilter {  /** * 这个方法是未登录需要执行的方法 */ @Override protected boolean onAccessDenied(ServletRequest request,       ServletResponse response) throws IOException {  HttpServletRequest httpRequest = (HttpServletRequest) request;     HttpServletResponse httpResponse = (HttpServletResponse) response;      Subject subject = getSubject(request, response);     if (subject.getPrincipal() == null) {      //设置响应头 httpResponse.setCharacterEncoding("UTF-8"); httpResponse.setContentType("application/json"); //设置返回的数据 YfpjResult result = YfpjResult.build(UserAuthStatusEnum.UNLOGIN.getCode(), UserAuthStatusEnum.UNLOGIN.getMsg()); //写回给客户端 PrintWriter out = httpResponse.getWriter(); out.write(JSONObject.toJSONString(result)); //刷新和关闭输出流 out.flush(); out.close();    } else {      //设置响应头   httpResponse.setCharacterEncoding("UTF-8");   httpResponse.setContentType("application/json");   //设置返回的数据   YfpjResult result = YfpjResult.build(UserAuthStatusEnum.UNAUTH.getCode(), UserAuthStatusEnum.UNAUTH.getMsg());   //写回给客户端   PrintWriter out = httpResponse.getWriter();   out.write(JSONObject.toJSONString(result));   //刷新和关闭输出流   out.flush();   out.close();    }     return false;  }}

4.以后在进行前后端分离的项目开发的时候，可以前端封装一个允许带cookie的ajax请求，同时封装一个统一的未登录或者未授权状态码的判断
