在Tomcat 7.0.47中部署RestEasy服务
我正在使用RestEasy开发Rest服务。 我需要在Tomcat中部署。 我认为我的web.xml中存在问题
这是我的web.xml：
MyServices resteasy.scan true resteasy.servlet.mapping.prefix /services resteasy-servlet org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher javax.ws.rs.Application com.service.services.MessageApplication resteasy-servlet /services/* 我有服务：
@GET @Path("/hello") @Produces({MediaType.APPLICATION_JSON}) public String Hello(String name) { System.out.println("Hello "+name); return("Hello "+name); }
当我部署时，我调用http://localhost:8080/MyServices/services/hello?name=Jesus Tomcat显示此错误：
java.lang.ClassNotFoundException: org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1702) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1547) 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:142) at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:1144) at org.apache.catalina.core.StandardWrapper.allocate(StandardWrapper.java:865) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:136) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:123) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:502) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:171) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:100) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:953) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:118) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:408) at org.apache.coyote.http11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:1041) at org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:603) at org.apache.tomcat.util.net.JIoEndpoint$SocketProcessor.run(JIoEndpoint.java:310) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) at java.lang.Thread.run(Thread.java:722)
当我包括resteasy-cache-core-3.0.6.Final, resteasy-jackson-provider-3.0.6.Final, resteasy-jaxrs-3.0.6.Final, resteasy-oauth-3.0.6.Final, resteasy-servlet-initializer-3.0.6.Final and resteasy-validator-provider-11-3.0.6.Final我在部署时resteasy-cache-core-3.0.6.Final, resteasy-jackson-provider-3.0.6.Final, resteasy-jaxrs-3.0.6.Final, resteasy-oauth-3.0.6.Final, resteasy-servlet-initializer-3.0.6.Final and resteasy-validator-provider-11-3.0.6.Final下一个错误：

我不知道我的问题是什么。 我是否需要将任何jar导入WEB-INF / lib？ 什么jar？ 我做错了什么？ 我不知道我是否以正确的方式致电我的服务。 另外，我不知道为什么tomcat不运行。 预先感谢。
您需要将resteasy库包含在WEB-INF / lib文件夹中。
您可以从这里下载http://sourceforge.net/projects/resteasy/files/Resteasy%20JAX-RS/
如果你使用Maven，你可以在http://mvnrepository.com/artifact/org.jboss.resteasy/resteasy-jaxrs/找到依赖项。
