我正在使用RestEasy开发Rest服务。我需要在Tomcat中进行部署。而且我认为我的web.xml中有问题
这是我的web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
<display-name>MyServices</display-name>
<!-- Auto scan REST service -->
<context-param>
<param-name>resteasy.scan</param-name>
<param-value>true</param-value>
</context-param>
<!-- this need same with resteasy servlet url-pattern -->
<context-param>
<param-name>resteasy.servlet.mapping.prefix</param-name>
<param-value>/services</param-value>
</context-param>
<servlet>
<servlet-name>resteasy-servlet</servlet-name>
<servlet-class>
org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher
</servlet-class>
<init-param>
<param-name>javax.ws.rs.Application</param-name>
<param-value>com.service.services.MessageApplication</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>resteasy-servlet</servlet-name>
<url-pattern>/services/*</url-pattern>
</servlet-mapping>
</web-app>
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,我呼叫
http://localhost:8080/MyServices/services/hello?name=Jesus
Tomcat显示此错误:

当包含

时,部署时间将出现下一个错误:dic 24, 2013 4:04:02 PM org.apache.catalina.startup.Catalina start

我不知道我的问题是什么。我需要将任何jar导入WEB-INF / lib吗?什么罐子?
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。
最佳答案
您需要将resteasy library包含在WEB-INF / lib文件夹中。
您可以从这里http://sourceforge.net/projects/resteasy/files/Resteasy%20JAX-RS/下载它们
如果使用Maven,则可以在http://mvnrepository.com/artifact/org.jboss.resteasy/resteasy-jaxrs/
