## 发布服务 ##

以下发布服务的代码与上次写的一样，但是TestWsdl类有了一些变化。

package com.test.wsdl;
    import javax.xml.ws.Endpoint;
    
    public class Test {
        
        public static void main(String[] args) {
        
            Endpoint.publish("http://localhost:8099/test",new TestWsdl());
        }
    }

TestWsdl如下，注意要加@WebService，@WebMethod，@WebParam注解

package com.test.wsdl;
    import javax.jws.WebMethod;
    import javax.jws.WebParam;
    import javax.jws.WebService;
    
    @WebService(targetNamespace = "http://wsdl.test.com/")
    public class TestWsdl {
        
    
        @WebMethod(action = "http://wsdl.test.com/testString")
        public String testString(@WebParam(name = "str",targetNamespace = "http://wsdl.test.com/") String  str){
        
            return "这个是TestString方法的返回内容，这个是你输入的值"+str;
        }
    }

## 调用代码 ##

### pom依赖 ###

我在处理过程中，出现了依赖冲突，依赖版本与代码不对应的情况，所以直接将全部用到的依赖全部放到下边。

    	</dependencies>

调用的时候，也出现引错包导致一直执行不成功的情况，所以将全部的代码贴在下边。

1.首先先定义枚举类，将服务地址，命名空间，方法都可以定义在枚举类中，方便更改名称与统一管理。

package com.test.wsdl;
    
    import lombok.AllArgsConstructor;
    import lombok.Getter;
    @Getter
    @AllArgsConstructor
    public enum WSDLEnum {
        
    
        SERVICE_URL("http://localhost:8099/test?wsdl","服务URL"),
        NAMESPACE_URI("http://wsdl.test.com/","命名URI"),
        TEST_STRING_METHOD("testString","teseString方法");
        private String name;
        private String describe;
    }

2.客户端

package com.test.wsdl;
    
    import org.apache.axis.Constants;
    import org.apache.axis.client.Call;
    import org.apache.axis.client.Service;
     
    import javax.xml.namespace.QName;
    import javax.xml.rpc.ParameterMode;
    
    public class WebServiceTest {
        
     
        public static void main(String[] args) {
        
            //服务地址
            String url = WSDLEnum.SERVICE_URL.getName();
            //命名空间
            String namespaceUri = WSDLEnum.NAMESPACE_URI.getName();
            //方法名
            String method = WSDLEnum.TEST_STRING_METHOD.getName();
            try {
        
                Service service = new Service();
                Call call = (Call) service.createCall();
                call.setTargetEndpointAddress(url);
                //设置要调用的方法
                call.setOperationName(new QName(namespaceUri, method));
                //设置要返回的数据类型
                call.setReturnType(new QName(namespaceUri, method), String.class);
                call.setUseSOAPAction(true);
                call.setSOAPActionURI(namespaceUri + method);
                //设置入参
                call.addParameter(new QName(namespaceUri, "str"), Constants.XSD_STRING, ParameterMode.IN);
                //调用方法并传递参数
                String resultStr = (String) call.invoke(new Object[]{
         new String("123")});
                System.out.println("服务调用结果：" + resultStr);
            } catch (Exception e) {
        
                e.printStackTrace();
            }
        }
    }

出现以下展示则调用成功。
