Java @RequestMapping在Spring 1.5.2.0版本中不起作用

我正在尝试运行一个spring boot项目。当我选择1.5.2版时，RequestMappingURL不起作用。它总是给我404错误

有人可以确认我是否有任何标签丢失或版本中的任何设置更改。或者其他我错过的东西

在尝试了所有场景之后，我终于将Spring引导版本更改为1.3.2.0版本

这样做后，它的工作很好。 我仍在试图找到为什么它不能在1.5.2版本上运行的答案

但为了解决这个错误，我对POM.xml文件做了如下更改

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.3.2.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

org.springframework.boot
spring启动程序父级
1.3.2.1发布

更改后，我也可以在日志中看到请求映射URL：

请注意，同时我更改了映射url的名称，因此可能与问题不同。

您尝试访问的url是什么？

package com.prizy.controller

：您的主类在哪里？您可以将主类与包名一起发布吗？此类中的其他方法是否有效？有没有可能不应该使用

get…

方法名？您是否尝试过将方法的名称或目标

/hi

更改为其他方法？他使用的是Spring Boot，它没有

web.xml

。
