解决 template might not exist or might not be accessible by any of the configured Template Resolvers

报错内容：

  Error resolving template [settlement/logisticsAll], template might not exist or might not be accessible by any of the configured Template Resolvers

报错原因：

在使用element.ui前端框架和axios技术时

1.访问Controller控制器时地址前面少加了“/”

2.Controller控制器返回数据时类上加的@Controller应该改为@RestController

或者这样写（它等价于@RestController）
