Spring Boot + Vue + Shiro 实现前后端分离,写得太好了!

一、前后端分离思想
二、后端 Springboot
@RequestMapping(value = "/add", method = RequestMethod.POST)
@ResponseBody
public JSONResult addClient(@RequestBody String param) {
JSONObject jsonObject = JSON.parseObject(param);
String task = jsonObject.getString("task");
List
三、前端 Vue + ElementUI + Vue router + Vuex + axios + webpack
https://cn.vuejs.org/v2/guide/ https://github.com/PanJiaChen/vue-admin-template/blob/master/README-zh.md https://github.com/PanJiaChen/vue-element-admin
XMLHttpRequest 会遵守同源策略 (same-origin policy). 也即脚本只能访问相同协议 / 相同主机名 / 相同端口的资源, 如果要突破这个限制, 那就是所谓的跨域, 此时需要遵守 CORS(Cross-Origin Resource Sharing) 机制。
@Component
public class CommonIntercepter implements HandlerInterceptor {
private final Logger logger = LoggerFactory.getLogger(this.getClass());
@Override
public boolean preHandle(HttpServletRequest request,
HttpServletResponse response, Object handler) throws Exception {
//允许跨域,不能放在postHandle内
response.setHeader("Access-Control-Allow-Origin", "*");
if (request.getMethod().equals("OPTIONS")) {
response.addHeader("Access-Control-Allow-Methods", "GET,HEAD,POST,PUT,DELETE,TRACE,OPTIONS,PATCH");
response.addHeader("Access-Control-Allow-Headers", "Content-Type, Accept, Authorization");
}
return true;
}
}
response.setHeader("Access-Control-Allow-Origin", "*");
if (request.getMethod().equals("OPTIONS")) {
response.addHeader("Access-Control-Allow-Methods", "GET,HEAD,POST,PUT,DELETE,TRACE,OPTIONS,PATCH");
response.addHeader("Access-Control-Allow-Headers", "Content-Type, Accept, Authorization");
}

并且注意,在 F12 看到的 js 提示错误的域名,是 js 写的那个域名,并不是代理后的域名。(l 楼主就遇到这个问题,后端地址缺少了查询参数,代理设置为后端地址,然而 F12 看到的错误依然还是本地的域名,并不是代理后的域名)
四、前后端分离项目中集成 shiro

if (request instanceof HttpServletRequest) {
if (((HttpServletRequest) request).getMethod().toUpperCase().equals("OPTIONS")) {
return true;
}
}
return super.isAccessAllowed(request, response, mappedValue);
}
@Override
protected boolean onAccessDenied(ServletRequest request, ServletResponse response) throws Exception {
HttpServletResponse res = (HttpServletResponse)response;
res.setHeader("Access-Control-Allow-Origin", "*");
res.setStatus(HttpServletResponse.SC_OK);
res.setCharacterEncoding("UTF-8");
PrintWriter writer = res.getWriter();
Mapmap= new HashMap<>();
map.put("code", 702);
map.put("msg", "未登录");
writer.write(JSON.toJSONString(map));
writer.close();
return false;
}
