Idea under Spring Boot+fremarker start error would dispatch back to the current handler URL [/hello] again. Check your Viewresolver setup!

Detailed error code (PS: the title of the main code to write the error)

Javax.servlet.ServletException:Circular view path [Hello]: would dispatch back to the current handler URL [/hello] again. Check your Viewresolver setup!    (Hint:this May is the result of a unspecified view, due to default view name generation.)

1. The origin of the problem

    IDEA中测试使用spring boot+freemarker时启动报错

2. Causes

    @RequestMapping("hello")中的路径与映射方法返回的视图名冲突了,不能写一样的

    (原来哪个代码图片找不到了,所以就直接写了一个,这只是例子,所以图中的错误可以忽略)

3. Workaround

    改一下视图名或者@RequestMapping 中的值就可以了....

4. Summary is not really a very advanced error, but it is easy for beginners to make mistakes, to avoid ... Reference
