【问题描述】:
尝试使用 spring 集成 ws 使用 web 服务,在 web 服务端我得到一个空指针,因为似乎传递的对象没有被编组或未映射到 xml,下面是调用调用的客户端的 sn-p服务 。
public class Main {
public static void main(String[] args) {
ClassPathXmlApplicationContext context
= new ClassPathXmlApplicationContext("springws.xml");
MessageChannel channel = context.getBean("request", MessageChannel.class);
String body = "<getPojo xmlns=\"http://johnson4u.com/\"><pojo>\n"
+ " <pojoId>23</pojoId>\n"
+ " <pojoName>dubic</pojoName>\n"
+ "</pojo></getPojo>";
MessagingTemplate messagingTemplate = new MessagingTemplate();
Message<?> message = messagingTemplate.sendAndReceive(
channel, MessageBuilder.withPayload(body).build());
System.out.println(message.getPayload());
}
WSDL 由 JAxWS 端点类生成
package com.johnson4u;
import javax.jws.WebService;
import javax.jws.WebMethod;
import javax.jws.WebParam;
@WebService(serviceName = "SpringService")
public class SpringService {
@WebMethod(operationName = "getPojo" )
public Pojo getPojo(@WebParam(Pojo pjRequest){
//Null Pointer occurs here as pjRequest might not be mapped to xml
System.out.println("Pojo name is "+pjRequest.getPojoName());
return new Pojo(234,"IM new Pojo");
}
还有 POJO
package com.johnson4u;
public class Pojo {
private int pojoId;
private String pojoName;
public Pojo(int pojoId, String pojoName) {
this.pojoId = pojoId;
this.pojoName = pojoName;
}
public int getPojoId() {
return pojoId;
}
public void setPojoId(int pojoId) {
this.pojoId = pojoId;
}
public String getPojoName() {
return pojoName;
}
public void setPojoName(String pojoName) {
this.pojoName = pojoName;
}
不幸的是,stackoverflow 无法正确格式化 wsdl,但命名空间 id 是基于包名com.johnson4u,下面是spring-ws-context.xml
<int:channel id="request" />
<int:channel id="response" />
<ws:outbound-gateway id="gateway"
request-channel="request"
uri="http://localhost:20151/SpringWs/SpringService?wsdl"/>
