我正在尝试使用 tomcat 发布一个简单的 java web 服务。参考下面的屏幕截图,我有HelloWorld.java,它是服务接口及其HelloWorldImpl.java实现类。

我还创建了web.xmlsun-jaxws.xml

当我右键单击项目时,选择Run As然后Run on Server,我收到 404 错误消息,如屏幕截图底部所示。

内部浏览器尝试访问的 URL是项目名称的http://localhost:8081/MySqlConnect/位置。MySqlConnect请注意,我使用8081的是端口号。

我也试过http://localhost:8081/HelloWorld/hello,但没有奏效。

我还提供了以下所有文件的代码。

我无法理解我哪里出错了?任何帮助表示赞赏。

HelloWorldImpl.java

package com.mycompany.service;
import javax.jws.WebService;
@WebService(endpointInterface = "com.mycompany.service.HelloWorld", serviceName = "HelloWorld")
public class HelloWorldImpl implements HelloWorld {

    @Override
    public String sayGreeting(String name) {

        return "Greeting " + name + "!";
    }
}

web.xml

正如这里所建议的,我下载了所有库并将其放入 tomcat lib 文件夹中,但现在我在日志中收到此错误:

com.sun.xml.ws.transport.http.servlet.WSServletContextListener parseAdaptersAndCreateDelegate
SEVERE: WSSERVLET11: failed to parse runtime descriptor: java.lang.NoSuchMethodError: com.sun.xml.ws.assembler.TubelineAssemblyController: method <init>()V not found
java.lang.NoSuchMethodError: com.sun.xml.ws.assembler.TubelineAssemblyController: method <init>()V not found

如果我将所有库添加到项目然后尝试运行它,我会收到以下错误:

com.sun.xml.ws.transport.http.servlet.WSServletContextListener parseAdaptersAndCreateDelegate
SEVERE: WSSERVLET11: failed to parse runtime descriptor: com.sun.xml.ws.util.ServiceConfigurationError: com.sun.xml.ws.policy.jaxws.spi.PolicyFeatureConfigurator: Provider com.sun.xml.ws.transport.tcp.policy.TCPTransportFeatureConfigurator is specified in jar:file:/C:/Apache-Tomcat-7/lib/webservices-rt-2.1-b16.jar!/META-INF/services/com.sun.xml.ws.policy.jaxws.spi.PolicyFeatureConfiguratorbut could not be instantiated: java.lang.ClassCastException

请注意:com.sun.xml.ws.policy.jaxws.spi.PolicyFeatureConfigurator 但无法实例化:java.lang.ClassCastException

正确的 url 是http://localhost:8081/MySqlConnect/hello因为MySqlConnect是你的上下文的名称,你好是 web 服务的 url。

它也是一个网络服务,因此要正确访问它,您可以进行 SOAP 调用。

但根本原因是您的 Web 应用程序由于找不到类而无法启动javax.xml.ws.soap.AddressingFeature$Responses

您是否添加了正确的依赖项?如果此类存在,则在这些依赖项中搜索。Response是 的内部AddressingFeature
