maven - 部署 gwtp hello world

Question

使用 https://github.com/ArcBees/ArcBees-tools/blob/master/archetypes/gwtp-basic/README.md 中的说明和 http://c.gwt-examples.com/home/maven/ide-import/eclipse我用 Maven 创建了一个 GWTP 项目。它在 Debug模式下运行良好，但我在部署它时遇到问题。

1. 运行命令 mvn gwt:compile
2. 将.war 文件复制到两个不同的Tomcat 服务器
3. 重启服务器
4. 浏览到文件的位置，我收到 404 错误

我在 catalina.out 中收到以下错误:

INFO: validateJarFile(/Library/Tomcat/webapps/test/WEB-INF/lib/gwt-user-2.5.1.jar) - jar not loaded. See Servlet Spec 2.3, section 9.7.2. Offending class: javax/servlet/Servlet.class

根据建议，我从 /WEB-INF/ 中删除了 gwt-user-2.5.1.jar，但出现以下错误:

SEVERE: Error configuring application listener of class com.test.server.guice.GuiceServletConfig java.lang.ClassNotFoundException: com.test.server.guice.GuiceServletConfig at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1714) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1559) at org.apache.catalina.core.DefaultInstanceManager.loadClass(DefaultInstanceManager.java:532) at org.apache.catalina.core.DefaultInstanceManager.loadClassMaybePrivileged(DefaultInstanceManager.java:514) at org.apache.catalina.core.DefaultInstanceManager.newInstance(DefaultInstanceManager.java:133) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:4727) at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5285) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150) at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:901) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:877) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:633) at org.apache.catalina.startup.HostConfig.deployDirectory(HostConfig.java:1105) at org.apache.catalina.startup.HostConfig$DeployDirectory.run(HostConfig.java:1664) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:439) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:303) at java.util.concurrent.FutureTask.run(FutureTask.java:138) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:895) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:918) at java.lang.Thread.run(Thread.java:680) Jun 17, 2013 4:23:28 PM org.apache.catalina.core.StandardContext listenerStart SEVERE: Skipped installing application listeners due to previous error(s)

当我尝试在我的本地 Tomcat 服务器和 arixe.com 服务器上部署它时，我遇到了同样的错误。

有什么建议吗？

干杯

不要在 war 中使用gwt-user，而是使用gwt-servlet。修改您的 pom 并删除:

<dependency>
    <groupId>com.google.gwt</groupId>
    <artifactId>gwt-user</artifactId>
    <version>${gwt.version}</version>
</dependency>

替换为:

<dependency>
    <groupId>com.google.gwt</groupId>
    <artifactId>gwt-servlet</artifactId>
    <version>${gwt.version}</version>
</dependency>
