Spring MVC 3：为不存在的方法找到了模糊映射

Question

I have this "create" method which maps /lists POST petitions. I made an overloaded method "createEmpty()" in order to try something, but later deleted as it throwed a org.springframework.beans.factory.BeanCreationException for ambiguous mapping.

The problem is that after I deleted said method, I still get the exception.

@Controller
public class ListsController {

@RequestMapping(value = "/lists", method = RequestMethod.POST)
public @ResponseBody List create(@RequestBody List list) {
    return list;
}

It seems that createEmpty() is cached somewhere...

Answer 1

Please try to do:
1. If you are using eclipse - Project -> Clean.
2. If you are using maven try to clean and/or install project before deploying.

I see you are using Jetty, maybe these links will help to solve your problems:

Jetty runs old war altought mvn clean is run

Answer 2

我在两个不同的控制器中具有相同的@RequestMapping值，我从其中一个控制器中删除了它，并且开始正常工作。
