ServerServiceDemo接口代码:
package com.rh.ws_test;
import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebService;
@WebService(name = "ServerServiceDemo", targetNamespace = "http://server.webservice.example.com")
public interface ServerServiceDemo {
@WebMethod
String emrService(@WebParam String data);
}
WebService涉及到的有这些 "四解三类 ", 即四个注解,三个类 @WebMethod, @WebService,@WebResult,@WebParam,SpringBus,Endpoint,EndpointImpl
一般我们都会写一个接口,然后再写一个实现接口的实现类,但是这不是强制性的
@WebService 注解表明是一个webservice服务。name:对外发布的服务名, 对应于
@WebMethod表示暴露的服务方法, 这里有接口ServerServiceDemo存在,在接口方法已加上@WebMethod, 所以在实现类中不用再加上,否则就要加上 operationName: 接口的方法名, action: 没发现又什么用处, exclude: 默认是false, 用于阻止将某一继承方法公开为web服务
@WebResult表示方法的返回值, name:返回值的名称, partName: , targetNamespace:,
header: 默认是false, 是否将参数放到头信息中,用于保护参数,默认在body中
@WebParam name:接口的参数, partName:, targetNamespace:
header: 默认是false, 是否将参数放到头信息中,用于保护参数,默认在body中, model:WebParam.Mode.IN/OUT/INOUT
ServerServiceDemoImpl接口实现类代码:
package com.rh.ws_test;
import org.springframework.stereotype.Component;
import javax.jws.WebParam;
import javax.jws.WebService;
@Component
@WebService(name = "ServerServiceDemo", targetNamespace = "http://server.webservice.example.com",
endpointInterface = "com.rh.ws_test.ServerServiceDemo")
public class ServerServiceDemoImpl implements ServerServiceDemo{
@Override
public String emrService(@WebParam String data) {
if(null == data || "".equals(data.trim())){
return "传入的参数为空";
}
return "调用成功";
}
}
WebServiceDemoTwo 代码:
package com.test.springboot.service;
import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebService;
@WebService(name = "WebServiceDemoTwo", targetNamespace = "http://server.webservice.example.com")
public interface WebServiceDemoTwo {
@WebMethod
String emrServiceThree(@WebParam String data);
@WebMethod
String emrServiceFour(@WebParam String data);
}
WebServiceDemoTwoImpl 代码
package com.test.springboot.service.impl;
import com.test.springboot.service.WebServiceDemoTwo;
import org.springframework.stereotype.Component;
import javax.jws.WebService;
@Component
@WebService(name = "WebServiceDemoTwo", targetNamespace = "http://server.webservice.example.com",
endpointInterface = "com.test.springboot.service.WebServiceDemoTwo")
public class WebServiceDemoTwoImpl implements WebServiceDemoTwo {
@Override
public String emrServiceThree(String data) {
return null;
}
@Override
public String emrServiceFour(String data) {
return null;
}
}
Apache CXF 核心架构是以BUS为核心,整合其他组件。Bus是CXF的主干, 为共享资源提供一个可配置的场所,作用类似于Spring的ApplicationContext,这些共享资源包括WSDl管理器、绑定工厂等。通过对BUS进行扩展,可以方便地容纳自己的资源,或者替换现有的资源。默认Bus实现基于Spring架构,通过依赖注入,在运行时将组件串联起来。BusFactory负责Bus的创建。默认的BusFactory是SpringBusFactory,对应于默认的Bus实现。在构造过程中,SpringBusFactory会搜索META-INF/cxf(包含在 CXF 的jar中)下的所有bean配置文件。根据这些配置文件构建一个ApplicationContext。开发者也可以提供自己的配置文件来定制Bus。
WebServiceConfig配置代码:
package com.test.springboot.config;
import com.test.springboot.service.WebServiceDemo;
import com.test.springboot.service.WebServiceDemoTwo;
import org.apache.cxf.Bus;
import org.apache.cxf.bus.spring.SpringBus;
import org.apache.cxf.jaxws.EndpointImpl;
import org.apache.cxf.transport.servlet.CXFServlet;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import javax.xml.ws.Endpoint;
@Configuration
public class WebServiceConfig {
@Autowired
private WebServiceDemo serverServiceDemo;
@Autowired
private WebServiceDemoTwo serverServiceDemoTwo;
@Bean(name = Bus.DEFAULT_BUS_ID)
public SpringBus springBus() {
return new SpringBus();
}
/**
* 此方法作用是改变项目中服务名的前缀名,此处127.0.0.1或者localhost不能访问时,请使用ipconfig查看本机ip来访问
* 此方法被注释后, 即不改变前缀名(默认是services), wsdl访问地址为 http://127.0.0.1:8080/services/ws/api?wsdl
* 去掉注释后wsdl访问地址为:http://127.0.0.1:8080/soap/ws/api?wsdl
* http://127.0.0.1:8080/soap/列出服务列表 或 http://127.0.0.1:8080/soap/ws/api?wsdl 查看实际的服务
* 新建Servlet记得需要在启动类添加注解:@ServletComponentScan
*
* 如果启动时出现错误:not loaded because DispatcherServlet Registration found non dispatcher servlet dispatcherServlet
* 可能是springboot与cfx版本不兼容。
* 同时在spring boot2.0.6之后的版本与xcf集成,不需要在定义以下方法,直接在application.properties配置文件中添加:
* cxf.path=/service(默认是services)

// @Bean
// public ServletRegistrationBean dispatcherServlet() {

@Bean

启动项目后访问: http://localhost:8083/services/
WebServiceTest 代码:
package com.test.springboot.webservice;
import org.apache.cxf.endpoint.Client;
import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;
public class WebServiceTest {
public static void main(String[] args) {
String url1 = "http://localhost:8080/test/bbb?wsdl";
String url2 = "http://localhost:8080/test/ccc?wsdl";
// client2(url2);
client1(url1);
}
// 创建动态客户端
public static void client1(String url) {
JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
Client client = dcf.createClient(url);
Object[] objects = new Object[0];
try {
// invoke("方法名",参数1,参数2,参数3....);
objects = client.invoke("emrService", "zhangsan123456");
System.out.println("emrService返回数据:" + objects[0]);
client.destroy();
} catch (Exception e) {
e.printStackTrace();
}
}
// 创建动态客户端
public static void client2(String url) {
JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
Client client = dcf.createClient(url);
Object[] objects = new Object[0];
try {
// invoke("方法名",参数1,参数2,参数3....);
objects = client.invoke("emrServiceThree", "zhangsan789");
System.out.println("emrServiceThree返回数据:" + objects[0]);
client.destroy();
} catch (Exception e) {
e.printStackTrace();
}
}
}
package com.rh.ws_test.client;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import org.apache.axis.encoding.XMLType;
import javax.xml.namespace.QName;
import javax.xml.rpc.ParameterMode;
import java.net.URL;
public class TestSoap {
public static void main(String[] args) throws Exception {
//一般如果没有注解targetNamespace的话,默认生成的就是接口这个文件的路径名
// String nameSpaceURI = "http://service.cm.com";
String nameSpaceURI = "http://server.webservice.example.com";
// String publishUrl = "http://localhost:8087/services/ServiceMonitor?wsdl";
String publishUrl = "http://localhost:8083/services/ws/api?wsdl";
Service service = new Service();
Call call = (Call) service.createCall();
call.setTargetEndpointAddress(new URL(publishUrl));
//指定接口路径,要调用的方法名
// call.setOperationName(new QName(nameSpaceURI, "monitor"));
call.setOperationName(new QName(nameSpaceURI, "emrService"));
//如果没用@WebParam(name="name")来表明参数名,则方法的入参是啥,这边就必须传一样的参数名才行。不然报错。
call.addParameter("arg0", XMLType.XSD_STRING, ParameterMode.IN);
// call.addParameter("age", XMLType.XSD_INT, ParameterMode.IN);
call.setReturnType(XMLType.XSD_STRING);
String name = "zhanglifeng";
int age = 18;
Object[] obj = new Object[] { name};
String result = (String) call.invoke(obj);
System.out.println(result);
}
}
注意:springboot开发webservice和axis组件开发webservice用法上有点区别
这里的访问路径的关系梳理:http://localhost:8080/test/ccc?wsdl
客户端调用时,确定访问路径后,我们调用时,要指定具体的方法名,可以直接在页面上看到。这样,就可以向具体的方法发起请求了。
