Java Spring MVC RESTful接口

我是spring新手，我想创建RESTful接口。我无法让简单的示例代码正常工作，也无法找出问题所在

以下代码触发错误：

• 从

  http://localhost:8080/myTestApp/test

  ：清单可能无效或无法打开文件
• 来源：System.Deployment

守则：

@RequestMapping(method=RequestMethod.GET, value="/test")
@ResponseBody
public String test(@RequestBody String body){
    String testString = test.CreateXml();
    return testString;
    //return "home";
}

如果我第一次用下面的代码在服务器中启动项目

@RequestMapping(method=RequestMethod.GET, value="/test")
//@ResponseBody
public String test(@RequestBody String body){
    String testString = test.CreateXml();
    //return testString;
    return "home";
}

然后我取消注释“@ResponseBody”和“returnteststring”，并在服务器启动和运行时为“return“home”行添加注释。 因此，代码看起来与前面的代码完全相同，但没有起作用。对代码进行更改后，我按Save，新代码将被动态地传递到服务器。 在这些更改之后，“测试”界面工作。若我重新启动服务器，我再次收到错误

我使用的是“Spring工具套件3.4.0”，服务器尝试了“VMware Fabric tc Server Developer Edition v2.9”和“Tomcat v7”。两台服务器都存在相同的问题，因此原因应该在spring配置的某个地方。 有人能帮忙吗

下面我附上了错误日志

“测试”是REST接口的示例代码。目前，它生成“虚拟”xml。下面是生成的伪xml

<root>
<!--This is a comment-->
<test name="value">My node value</test>
</root>

我没有涉及上下文xml，它是自动生成的。下面是servlet-context.xml

<?xml version="1.0" encoding="UTF-8"?>

    </beans:bean>

    <context:component-scan base-package="com.mobile.myTestApp" />



</beans:beans>

stacktrace和/或日志。还有什么是

测试

，你能分享它的声明和

CreateXml

方法的代码吗？也包括你的应用程序上下文xml，这样我们就可以了解你是如何配置所有内容的。我用你提出的所有内容更新了这个问题。据我所知，所有内容都应该有效，所以我认为问题可能存在于自动生成的配置文件中。奇怪的是，如果我在服务器启动和运行时更改代码，那么一切都会正常运行。。。
