在 jetty-maven-plugin 中未调用 Spring 映射的 servlet

Question

我不得不从maven-jetty-plugin 迁移到jetty-maven-plugin 。 当我使用jetty:run启动 jetty 时，我可以看到上下文已部署，应用程序正在初始化但未找到 servlet。 它与maven-jetty-plugin一起正常工作。

爪哇

@RequestMapping(value = "/handshake", method = RequestMethod.POST, produces = "application/json;charset=UTF-8")
public void performHandShake(@org.springframework.web.bind.annotation.RequestBody String requestData, HttpServletResponse response) throws IOException {

网页.xml

<servlet>
    <servlet-name>dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

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

从有关jetty-maven-plugin配置的文档来看，似乎在contextPath他们建议您可能（我必须承认非常模糊）需要添加前导正斜杠"/" ，以便您的 maven 插件定义应为：

    <plugin>
        <groupId>org.eclipse.jetty</groupId>
        <artifactId>jetty-maven-plugin</artifactId>
        <version>${maven-jetty-plugin.version}</version>

        <configuration>
            <webApp>
                <contextPath>/pos-json</contextPath>
            </webApp>
            <scanIntervalSeconds>0</scanIntervalSeconds>
        </configuration>
    </plugin>

希望这可以帮助！
