我正在尝试将基于xml的Spring MVC应用程序移动到基于Java配置的应用程序。与maven中可用的各种java.servlet类似乎不匹配。例如,有些提供addServlet()方法,有些则没有。
这是我的配置类:
public class MyWebAppInitializer implements WebApplicationInitializer { @Override public void onStartup(ServletContext container) throws ServletException { AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext(); rootContext.register(JpaSandboxConf.class); ServletRegistration.Dynamic registration = container.addServlet("dispatcher", new DispatcherServlet()); registration.setLoadOnStartup(1); registration.addMapping("/myapp/*"); } }
这似乎没有争议。为了得到
container.addServlet()
方法,我将此包含在pom中:
<dependency> <groupId>org.apache.tomcat</groupId> <artifactId>tomcat-servlet-api</artifactId> <version>7.0.30</version> </dependency>
我尝试了这个,但是DID下的条目中的ServletContext类不起作用(因为它不提供addServlet()方法):
<dependency> <groupId>javax.servlet</groupId> <artifactId>com.springsource.javax.servlet</artifactId> <version>2.5.0</version> <scope>provided</scope> </dependency>
当我尝试使用
mvn clean tomcat7:run
我不幸地获得
SEVERE: A child container failed during start java.util.concurrent.ExecutionException: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Tomcat].StandardHost[localhost].StandardContext[/]] at java.util.concurrent.FutureTask$Sync.innerGet(FutureTask.java:252) at java.util.concurrent.FutureTask.get(FutureTask.java:111) at org.apache.catalina.core.ContainerBase.startInternal(ContainerBase.java:1130) at org.apache.catalina.core.StandardHost.startInternal(StandardHost.java:782) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1568) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1558) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:334) at java.util.concurrent.FutureTask.run(FutureTask.java:166) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:722) Caused by: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Tomcat].StandardHost[localhost].StandardContext[/]] at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:154) ... 7 more Caused by: java.lang.ClassCastException: org.springframework.web.SpringServletContainerInitializer cannot be cast to javax.servlet.ServletContainerInitializer at org.apache.catalina.startup.ContextConfig.getServletContainerInitializer(ContextConfig.java:1543) at org.apache.catalina.startup.ContextConfig.processServletContainerInitializers(ContextConfig.java:1464) at org.apache.catalina.startup.ContextConfig.webConfig(ContextConfig.java:1190) at org.apache.catalina.startup.ContextConfig.configureStart(ContextConfig.java:825) at org.apache.catalina.startup.ContextConfig.lifecycleEvent(ContextConfig.java:300) at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:119) at org.apache.catalina.util.LifecycleBase.fireLifecycleEvent(LifecycleBase.java:90) at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5161) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150) ... 7 more
我看到一个类来自Spring框架,另一个来自javax.servlet,但是再次,该方法在Spring提供的类中不存在(令人沮丧,因为该示例存在于Spring 3.2文档本身。
我正在使用Spring 3.2。我没有使用Eclipse(所有示例都基于Eclipse,我在IntelliJ中)。这是一个Maven项目
感谢
这里提供了一个更好的pom servlet 3.0 api依赖项条目-https: //github.com/SpringSource/greenhouse/tree/servlet3,你还应该将范围标记为provided,否则jar将包含在你的最终战争中,这会干扰容器提供的jar,这似乎是你的情况。
