urlrewrite,java报错NoSuchmethoderror

结论性意见：@RequestMapping 如果【只】写在类上是无效的。

测试1 :即使只有一种方法，也不执行。 正常的开始！

@ slf4j @ rest controller @ request mapping (value='/demo '，method=RequestMethod.GET ) publicclasscontrolllertest { put

@ slf4j @ rest controller @ request mapping (value='/demo2'，method=RequestMethod.GET ) publicclasscontrollertest2{

@ slf4j @ rest controller @ request mapping (value='/demo3'，method=RequestMethod.GET ) publiccclasscontrolllertest3{ }
