java - gwt应用程序和spring MVC返回错误404

问题描述

我有一个带有 spring core 4 框架的 gwt 应用程序。在服务器部分，我添加了一个 RestController 来为其他应用程序生成 Web 服务。我为此使用了 Java 配置，但是现在当我在嵌入式服务器 Jetty 中运行应用程序时，gwt 应用程序运行完美，但 web 服务（错误 404）运行良好，当我在 jboss 7.1.1 中运行战争时，Rest WebService 运行良好但不是gwt 应用程序（错误 404）。

这是我的新配置：

    @RestController
    @RequestMapping(value = "/historiquedlo", produces = "application/hal+json", consumes = { "text/plain","text/html","application/*" })
    @Transactional
    public class WsHistoriqueDlo {

        /**
         * En dur dans PCD
         */
        private static final String DEFAULT_CODE_PRODUIT_DL = "L20";

        @Autowired
        private EntityManager entityManager;

        /**
         * Méthode avec 4 paramètres : Code produit par défaut L20
         * 
         * @param siren
         * @param debut
         *            : ISO Date Format yyyy-MM-dd, e.g. "2000-10-31".
         * @param sirenGroupe
         * @param sirenTeteGroupe
         * @return ResponseEntity<Resources<HistoriqueDlo>>
         */
        @RequestMapping(value = "/{siren}/{debut}", method = RequestMethod.GET)
        public ResponseEntity<Resource<InfoHistoriqueDlo>> findHistoriqueDlo(@PathVariable("siren") final String siren,
                @PathVariable("debut") @DateTimeFormat(iso = DateTimeFormat.ISO.DATE) final String debut,
                @RequestParam(name="sirenGroupe", required=false) final String sirenGroupe,
                @RequestParam(name="sirenTeteGroupe", required=false) final String sirenTeteGroupe) { 
.
.
.}  
public class SoftWebInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
 @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class[] { SoftWebConfig.class };
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return null;
    }

    @Override
    protected String[] getServletMappings() {
         return new String[]{"/*","/ws/*"};     }

}

对于 SoftWebConfig，我使用了这个配置：

@Configuration
@Import(SoftDBConfig.class)
@EnableScheduling
@EnableWebMvc
@EnableHypermediaSupport(type = { HypermediaType.HAL })
@ComponentScan(basePackages = { "com.rcibanque.socle.server.*", "com.rcibanque.sof.server.*",
        "com.rcibanque.socle.server.ws.*" })
public class SoftWebConfig implements SchedulingConfigurer {

    @Override
    public void configureTasks(ScheduledTaskRegistrar taskRegistrar) {
        taskRegistrar.setScheduler(taskExecutor());
    }

    @Bean(name = "TOPCAR-EXECUTOR", destroyMethod = "shutdown")
    public Executor taskExecutor() {
        return Executors.newScheduledThreadPool(1);
    }

}

我的 web.xml 是这样的：

我将http://localhost:8080/rci_sof/Index.html用于 gwt 应用程序，对于 Web 服务，我使用此 Url：http://localhost:8080/rci_sof/ws/historiquedlo/30365637500209/L20/2​​018-06 -20?sirenGroupe=950425694&sirenTeteGroupe=447938036。

谢谢你 。

解决方案

您可以使用web.xml文件
或
使用AbstractAnnotationConfigDispatcherServletInitializer.class（来自 servlet 版本 3.0+）初始化您的应用程序。
目前，您同时提供两者，并且只有一个可以工作。

最简单的方法可能是初始化您的调度程序 servletweb.xml并删除SoftWebInitializer.class.

将此添加到您的 web.xml（为您的 SoftWebConfig 使用正确的路径）：所有 spring 控制器现在都将具有基本 urllocalhost:8080/ws

  <servlet>
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
    <init-param>
      <param-name>contextClass</param-name>
      <param-value>org.springframework.web.context.support.AnnotationConfigWebApplicationContext</param-value>
    </init-param>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>XXXXX.XXXXX.SoftWebConfig</param-value>
    </init-param>
  </servlet>

<servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/ws/*</url-pattern>
</servlet-mapping>

使用 spring WebApplicationInitializer而不是web.xml文件仅适用于 servlet 版本 3.0+，但您的 web.xml 当前指定版本 2.5。
因此，要实际使用，AbstractAnnotationConfigDispatcherServletInitializer您必须删除web.xml文件并将所有内容迁移到新的 Initializer 文件。
还需要支持 servlet 3.0 及更高版本的网络服务器。Jetty 至少需要版本 8。
