java - 在 WebSphere Application Server 8 上部署 Spring MVC 3 Rest

Question

我正在尝试在 WebSphere Application Server 8.0 上部署 Spring 3 MVC Rest 应用程序，但没有取得任何成功。

这是我的 Controller 类

`

@Controller
public class BookingService {

    public BookingService() {
        System.out.println("test");
    }

    @RequestMapping(value="/test", method=RequestMethod.GET, produces="application/xml")
    @ResponseBody
    public String test() {
        return "<test>test</test>";
    }
}

`

web.xml - servlet 规范 3

`

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="3.0"
    xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/api/*</url-pattern>
    </servlet-mapping>

</web-app>

我确认它确实适用于 tomcat。在 tomcat 日志中正在创建映射。

INFO: Mapped "{[/test],methods=[GET],params=[],headers=[],consumes=[],produces=[application/xml],custom=[]}" onto public java.lang.String com.westjet.ens.services.BookingService.test()


curl http://localhost:8080/ens-das-web/api/test返回 HTTP 200。

但是在 was 日志中，这并没有出现并且正在 curl http://localhost:9080/my-service-web/api/test返回 404 和以下响应。

` 错误 404:SRVE0295E:报告错误:404

`

WAS 日志在执行 curl 时也会显示以下内容。

我能够解决这个问题。出于某种原因，maven 没有清理 WEB-INF/classes 文件夹，我的@Controller 类不可用。
