这段代码是在使用Apache CXF框架创建一个JAX-WS代理工厂对象,然后通过该工厂对象设置要调用的服务接口类型和服务的地址。其中,setServiceClass方法设置服务接口类型,setAddress方法设置服务地址。通过这些设置后,可以使用代理工厂对象创建一个代理对象来实现对远程服务的调用。
相关问题
JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean(); factory.setServiceClass(UserService.class); factory.setAddress("http://localhost:8080/service/user");中无法识别setServiceClass
这种情况很可能是因为没有正确导入相关的类库。在这段代码中,setServiceClass方法是JaxWsProxyFactoryBean类的方法,而UserService类是你自己定义的服务接口类。因此,需要确保你的代码中正确导入了JaxWsProxyFactoryBean类所在的类库,一般来说是Apache CXF框架的类库,否则编译器就无法识别setServiceClass方法。
使用Java提供的handler机制在客户端对SOAP请求包注入header。在实验一springboot框架下的CXF建立的web服务的基础上,对客户端产生的SOAP请求包加入header,header有一个子元素student,命名空间为你自己项目使用的命名空间;student有三个子元素sno和sname、time,即学号,姓名和当前系统时间。参考如下形式: <SOAP-ENV:Header> <student xmlns="http://hello.soapHandlerEx/"> <sno>001</sno> <sname>你的名字</sname> <time>2023/5/10</time> </student> </SOAP-ENV:Header> 输出方式可以采用命令行或文本记录。 2、在服务端对SOAP请求包进行解析,获得头部,并展示出头部的信息,展示方式可以自行设计。
1. 在客户端对SOAP请求包注入header
可以使用Java提供的SOAPHandler机制,在客户端请求WebService时,在SOAP消息头中添加指定的Header。
首先定义一个SOAPHandler实现类:
```java
package com.example.demo.handler;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
import java.util.Set;
import javax.xml.namespace.QName;
import javax.xml.soap.SOAPElement;
import javax.xml.soap.SOAPEnvelope;
import javax.xml.soap.SOAPHeader;
import javax.xml.soap.SOAPMessage;
import javax.xml.ws.handler.MessageContext;
import javax.xml.ws.handler.soap.SOAPHandler;
import javax.xml.ws.handler.soap.SOAPMessageContext;
public class MySOAPHandler implements SOAPHandler<SOAPMessageContext> {
private static final String NAMESPACE_URI = "http://hello.soapHandlerEx/";
@Override
public boolean handleMessage(SOAPMessageContext context) {
Boolean isOutbound = (Boolean) context.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
if (isOutbound) {
try {
SOAPMessage soapMessage = context.getMessage();
SOAPEnvelope envelope = soapMessage.getSOAPPart().getEnvelope();
SOAPHeader header = envelope.getHeader();
if (header == null) {
header = envelope.addHeader();
}
SOAPElement studentElement = header.addChildElement(new QName(NAMESPACE_URI, "student"));
SOAPElement snoElement = studentElement.addChildElement("sno");
snoElement.setTextContent("001");
SOAPElement snameElement = studentElement.addChildElement("sname");
snameElement.setTextContent("你的名字");
SOAPElement timeElement = studentElement.addChildElement("time");
LocalDateTime now = LocalDateTime.now();
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy/MM/dd");
timeElement.setTextContent(now.format(formatter));
} catch (Exception e) {
e.printStackTrace();
}
}
return true;
}
@Override
public boolean handleFault(SOAPMessageContext context) {
return true;
}
@Override
public void close(MessageContext context) {
}
@Override
public Set<QName> getHeaders() {
return null;
}
}
```
然后在客户端代码中添加Handler:
```java
JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
factory.setServiceClass(HelloWorld.class);
factory.setAddress("http://localhost:8080/helloWorld");
factory.getHandlers().add(new MySOAPHandler());
HelloWorld helloWorld = (HelloWorld) factory.create();
String result = helloWorld.sayHello("World");
System.out.println(result);
```
这样,在请求WebService时,就会在SOAP消息头中添加指定的Header。
2. 在服务端对SOAP请求包进行解析
可以使用Java提供的SOAPHandler机制,在服务端接收到WebService请求时,从SOAP消息头中解析指定的Header。
首先定义一个SOAPHandler实现类:
```java
package com.example.demo.handler;
import java.util.Set;
import javax.xml.namespace.QName;
import javax.xml.soap.SOAPElement;
import javax.xml.soap.SOAPEnvelope;
import javax.xml.soap.SOAPHeader;
import javax.xml.soap.SOAPMessage;
import javax.xml.ws.handler.MessageContext;
import javax.xml.ws.handler.soap.SOAPHandler;
import javax.xml.ws.handler.soap.SOAPMessageContext;
public class MySOAPHandler implements SOAPHandler<SOAPMessageContext> {
private static final String NAMESPACE_URI = "http://hello.soapHandlerEx/";
@Override
public boolean handleMessage(SOAPMessageContext context) {
Boolean isOutbound = (Boolean) context.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
if (!isOutbound) {
try {
SOAPMessage soapMessage = context.getMessage();
SOAPEnvelope envelope = soapMessage.getSOAPPart().getEnvelope();
SOAPHeader header = envelope.getHeader();
if (header != null) {
SOAPElement studentElement = (SOAPElement) header.getElementsByTagNameNS(NAMESPACE_URI, "student").item(0);
if (studentElement != null) {
SOAPElement snoElement = (SOAPElement) studentElement.getElementsByTagName("sno").item(0);
String sno = snoElement.getTextContent();
SOAPElement snameElement = (SOAPElement) studentElement.getElementsByTagName("sname").item(0);
String sname = snameElement.getTextContent();
SOAPElement timeElement = (SOAPElement) studentElement.getElementsByTagName("time").item(0);
String time = timeElement.getTextContent();
System.out.println("SOAP Header: sno=" + sno + ", sname=" + sname + ", time=" + time);
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
return true;
}
@Override
public boolean handleFault(SOAPMessageContext context) {
return true;
}
@Override
public void close(MessageContext context) {
}
@Override
public Set<QName> getHeaders() {
return null;
}
}
```
然后在服务端代码中添加Handler:
```java
@Bean
public Endpoint endpoint() {
EndpointImpl endpoint = new EndpointImpl(bus, new HelloWorldImpl());
endpoint.publish("/helloWorld");
endpoint.getBinding().getHandlerChain().add(new MySOAPHandler());
return endpoint;
}
```
这样,在接收到WebService请求时,就可以从SOAP消息头中解析指定的Header,并展示出来。
