No 'Access-Control-Allow-Origin' header is present on the requested resource. 在项目开发中遇到该问题，从网上看到资料说是ajax异步访问造成的。这是因为搜索的方向错误了重点关注'http://localhost:8088' is therefore not allowed access. 这一部分。发现请求的方式不一致，请求路径是localhost，而实际路径中应该是ip地址。修改请求路径后发现问题解决。因为是用idea开发的在configurations 中修改访问路径后解决。 

　　　另外需要补充一点的是，关注下报错的访问路径跟实际访问路径，如果不一致但是项目在自己电脑上能正常使用，考虑下路径是截取了数据库中的部分字段，因为写死了造成换机器后不能使用了
