CXF+Spring 发布与调用webservice

这几天接手一个项目，应用的是CXF和Spring编写webservice,对于第一次编写接口的菜鸟来说，只调用过别人的接口，这是让我有些头疼的，代码很容易就搞定了，毕竟是复制修改，但是关于这个怎么暴露给别人调用，百度了很多，试过直接在main方法中暴露，然后客户端调用，但是调用报空指针，后来找到原因之后，不知道该接口的暴露的url，交接文档中也没有注明，当时我心里一万个草泥马飞奔而过。。。这些请在下文详细看：

一、正确的示范，发布调用成功

1、准备需要的关于cxf的jar包： 2.7.2的版本可以在这里下载https://download.csdn.net/download/luuvyjune/10523675

2、web.xml 配置

  <servlet>
    <servlet-name>CXFServlet</servlet-name>
    <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
    <load-on-startup>2</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>CXFServlet</servlet-name>
    <url-pattern>/ws/*</url-pattern>
  </servlet-mapping>

3、spring-cxf.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
	xmlns:jaxws="http://cxf.apache.org/jaxws" xmlns:context="http://www.springframework.org/schema/context"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://cxf.apache.org/jaxws
        http://cxf.apache.org/schemas/jaxws.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">

	<import resource="classpath:/META-INF/cxf/cxf.xml" />
	<import resource="classpath:/META-INF/cxf/cxf-servlet.xml" />
	
	<jaxws:endpoint id="patientEventWebservice" implementor="cn.myjob.empi.webservice.PEventLogXmlImpl " address="/PatientEventWebservice" />
</beans>

4、代码（只是关于这个接口的代码）：

PatientEventWebservice.java

import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebService;

@WebService
public interface PatientEventWebservice {	
	@WebMethod(action="getPatientEventLogByMpi")
	String getPatientEventLogByMpi(@WebParam(name="text") String inputString);

}

PEventLogXmlImpl.java

@WebService(endpointInterface="cn.myjob.empi.webservice.PatientEventWebservice",serviceName="PEventLogXmlImpl")
public class PEventLogXmlImpl implements PatientEventWebservice {
	
	private Logger log = Logger.getLogger(PEventLogXmlImpl.class);
	@Autowired
	private QueryPatientEventLogByMpiService queryPatientEventLogByMpiService;
	

	@Override
	public String getPatientEventLogByMpi(String inputString) {
		log.info("\n[查询事件信息]"+inputString);
		XStream xstream = new XStream();
		xstream.aliasType("XmlResponse", XmlResponse.class);
		xstream.aliasType("PEvent", PEvent.class);
		System.out.println(queryPatientEventLogByMpiService);
		if(queryPatientEventLogByMpiService == null){
			queryPatientEventLogByMpiService = ContextLoaderListener.getCurrentWebApplicationContext().getBean(QueryPatientEventLogByMpiService.class);
		}
		XmlResponse<PEvent> xml  = queryPatientEventLogByMpiService.process(inputString);
		return xstream.toXML(xml);
	}
	
}

PEventLogWebService.java

public abstract class PEventLogWebService {
	protected Logger log = Logger.getLogger(this.getClass());
	
	public abstract  XmlResponse<PEvent> process(String inputString);
	
}

QueryPatientEventLogByMpiService.java

@Service
public class QueryPatientEventLogByMpiService extends PEventLogWebService{
	@Override
	public XmlResponse<PEvent> process(String inputString) {
		XmlResponse<PEvent> response = null;
		Results<XmlRequest> parseResult = null;
		try {
			parseResult = processString(inputString);
			if(parseResult.getSuccess()){
				processValidate(parseResult.getData());
				response = processBusi(parseResult.getData());
			}
		} catch (Exception e) {
			e.printStackTrace();
			log.error(e);
			if(response ==null){
				response = new XmlResponse<PEvent>();
				if(parseResult!=null&&parseResult.getData()!=null){
					response.setMSH(parseResult.getData().getMSH());
				}
				response.setEVN(IdService.getEvn());
			}
			response.setCODE(SystemCode._EXCEPTION.getKey());
			response.setDETAIL(e.getMessage());
			response.setSTACK_TRANCE(e.getStackTrace());
		}
		return response;
	}

}

这个类展示为service层，里面的方法会调用持久层并返回结果，此处代码省略。

6、tomcat启动web服务，浏览器输入地址：

http://localhost:8082/emp3/ws/PatientEventWebservice?wsdl

webservice暴露的地址命名：http://ip:端口/项目名/web.xml中cxf配置的匹配值/webservice接口名称?wsdl

结果如下：
