java - Spring MVC 3 : Ambiguous mapping found for a non existing method

Question

我有这个映射/列出 POST 请愿的“创建”方法。我创建了一个重载方法“createEmpty()”来尝试一些事情，但后来被删除，因为它抛出了一个用于模糊映射的 org.springframework.beans.factory.BeanCreationException。

问题是在我删除上述方法后，我仍然得到异常。

@Controller
public class ListsController {

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

似乎 createEmpty() 缓存在某处......

请尝试做:
1. 如果你使用的是eclipse - Project -> Clean.
2. 如果您使用的是 Maven，请尝试在部署之前清理和/或安装项目。

我看到您正在使用 Jetty，也许这些链接将有助于解决您的问题:
