WebService-06-CXF与Spring集成

前言

自3月份到一家快递公司之后，就极少有时间来写博客了，进去的第一个周末就加班，做公司的开放平台，协助一个小伙伴写WebService接口，用的就是CXF，正好这个东西以前使用过。现在快7月了，以前写的东西，还木有写完，今天继续，将以前未写完的东西，写完整。

准备工作

这次的样例，都是在以前的基础上写的，主要贴出主要的代码，服务端和客户端都与Spring集成，使用了拦截器、Map数据类型等

服务端

共计写了四个服务，第一个主要说明服务端有多种发布方式，第二和第三实现类是相同的，区别在于第三个有拦截器，第四个包括拦截器和Map的数据类型，这些配置文件的注释中也有。

配置文件内容如下：

第一个服务的类：

package com.wds.cxf.spring.server.impl;

import javax.jws.WebService;

@WebService
public class NoInterfaceServiceImpl {
	
	public String test(){
		return "Hello, this is test method";
	}
}

第二个和第三个服务的接口及实现类

package com.wds.cxf.spring.server;

import java.util.List;

import javax.jws.WebService;

@WebService
public interface IUserService {
	public List getUserName();
}

实现类
package com.wds.cxf.spring.server.impl;

import java.util.ArrayList;
import java.util.List;

import javax.jws.WebService;
import javax.xml.ws.BindingType;
import javax.xml.ws.soap.SOAPBinding;

import com.wds.cxf.spring.server.IUserService;

@WebService(endpointInterface="com.wds.cxf.spring.server.IUserService",serviceName="UserService")
@BindingType(value=SOAPBinding.SOAP12HTTP_BINDING)
public class UserServiceImpl implements IUserService {

	@Override
	public List getUserName() {
		List userNameList = new ArrayList();
		
		String userName = "firstName";
		userNameList.add(userName);
		userName = "secondName";
		userNameList.add(userName);
		userName = "thirdName";
		userNameList.add(userName);
		
		return userNameList;
	}

}

第四个服务

package com.wds.cxf.spring.server;

import java.util.List;
import java.util.Map;

import javax.jws.WebService;
import javax.xml.bind.annotation.adapters.XmlJavaTypeAdapter;

import com.wds.cxf.spring.server.adapter.MappingUser;

@WebService
public interface ISecurityService {
	@XmlJavaTypeAdapter(value=MappingUser.class)
	public Map> getAuthority();
}

实现类
package com.wds.cxf.spring.server.impl;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import com.wds.cxf.spring.server.ISecurityService;
import com.wds.cxf.spring.server.User;

public class SecurityServiceImpl implements ISecurityService {

	@Override
	public Map> getAuthority() {
		Map> result = new HashMap>();
		User u = null;
		List users = new ArrayList(10);
		String key = "seriail1";
		for (int i = 0; i < 10; i++) {
			u = new User("name" + i, "code--" + i);
			users.add(u);
		}
		result.put(key, users);
		
		users = new ArrayList(10);
		key = "seriail2";
		for (int i = 20; i < 30; i++) {
			u = new User("name" + i, "code--" + i);
			users.add(u);
		}
		result.put(key, users);
		
		return result;
	}

}

类型转换的适配类两个

package com.wds.cxf.spring.server.adapter;

import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.Map.Entry;

import javax.xml.bind.annotation.adapters.XmlAdapter;

import com.wds.cxf.spring.server.User;

public class MappingUser extends XmlAdapter>>{

	@Override
	public Map> unmarshal(MappingUserValue src)
			throws Exception {
		Map> target = new HashMap>();
		for (MappingUserValue.Entry entry : src.getEntries()) {
			target.put(entry.getKey(), entry.getValue());
		}
		return target;
	}

	@Override
	public MappingUserValue marshal(Map> src) throws Exception {
		MappingUserValue result = new MappingUserValue();
		MappingUserValue.Entry e = null;
		for (Entry> entry : src.entrySet()) {
			e = new MappingUserValue.Entry();
			e.setKey(entry.getKey());
			e.setValue(entry.getValue());
			result.getEntries().add(e);
		}
		return result;
	}

}

package com.wds.cxf.spring.server.adapter;

import java.util.ArrayList;
import java.util.List;

import com.wds.cxf.spring.server.User;

public class MappingUserValue {
	private List entries = new ArrayList();

	public List getEntries() {
		return entries;
	}

	public void setEntries(List entries) {
		this.entries = entries;
	}
	
	public static class Entry {
		private String key;
		private List value;

		public List getValue() {
			return value;
		}

		public void setValue(List value) {
			this.value = value;
		}

		public String getKey() {
			return key;
		}

		public void setKey(String key) {
			this.key = key;
		}

	}

}

拦截器

package com.wds.cxf.spring.server.interceptor;

import java.util.List;

import javax.xml.namespace.QName;

import org.apache.cxf.binding.soap.SoapMessage;
import org.apache.cxf.headers.Header;
import org.apache.cxf.interceptor.Fault;
import org.apache.cxf.message.Message;
import org.apache.cxf.phase.AbstractPhaseInterceptor;
import org.apache.cxf.phase.Phase;
import org.w3c.dom.Element;
import org.w3c.dom.NodeList;

public class HeaderHandlerInterceptor extends AbstractPhaseInterceptor {

	public HeaderHandlerInterceptor(String phase) {
		super(Phase.PRE_INVOKE);
	}
	
	public HeaderHandlerInterceptor() {
		this(null);
	}

	@Override
	public void handleMessage(Message message) throws Fault {
		SoapMessage msg = (SoapMessage)message;
		List
 headers = msg.getHeaders();
		
		if(headers == null || headers.size() < 1){
			throw new Fault(new IllegalArgumentException("There have no header node!"));
		}
		
		Header firstHeader = headers.get(0);
		
		for (Header header : headers) {
			QName qName = header.getName();
			System.out.println(qName);
		}
		
		Element element = (Element)firstHeader.getObject();
		
		NodeList usernameNode = element.getElementsByTagName("username");
		NodeList passwordNode = element.getElementsByTagName("password");
		
		if(usernameNode == null || usernameNode.getLength() != 1){
			throw new Fault(new IllegalArgumentException("not valid username"));
		}
		
		if(passwordNode == null || passwordNode.getLength() != 1){
			throw new Fault(new IllegalArgumentException("not valid password"));
		}
		
		String userName = usernameNode.item(0).getTextContent();
		String userPass = passwordNode.item(0).getTextContent();
		
		if(!("admin".equals(userPass) && "admin".equals(userName))){
			throw new Fault(new IllegalArgumentException("username or password is not valid"));
		}
	}

}

至此，服务端的代码，全部齐了

客户端

客户端的代码是需要CXF的命令生成

使用CXF的命令，生成客户端代码，加上面的配置，此外还需要一个拦截器，代码如下：

package com.wds.java.cxf.interceptor;

import java.util.List;

import javax.xml.namespace.QName;

import org.apache.cxf.binding.soap.SoapMessage;
import org.apache.cxf.headers.Header;
import org.apache.cxf.helpers.DOMUtils;
import org.apache.cxf.interceptor.Fault;
import org.apache.cxf.phase.AbstractPhaseInterceptor;
import org.apache.cxf.phase.Phase;
import org.w3c.dom.Document;
import org.w3c.dom.Element;

public class ClientHeaderInterceptor extends AbstractPhaseInterceptor{

	private String username;
	private String password;
	
	public ClientHeaderInterceptor(String phase) {
		super(Phase.PREPARE_SEND);//在准备发送SOAP消息时，调用此拦截器
	}
	
	public ClientHeaderInterceptor(String username, String password) {
		this("");
		this.username = username;
		this.password = password;
	}

	@Override
	public void handleMessage(SoapMessage msg) throws Fault {
		List
 headers = msg.getHeaders();
		Document doc = DOMUtils.createDocument();
		Element authEle = doc.createElement("header");
		Element usernameEle = doc.createElement("username");
		Element passwordEle = doc.createElement("password");
		
		usernameEle.setTextContent(username);
		passwordEle.setTextContent(password);
		
		authEle.appendChild(usernameEle);
		
		authEle.appendChild(passwordEle);
		
		Header header = new Header(new QName("authHeaer"), authEle);
		
		headers.add(header);
		
		authEle = doc.createElement("headerTwo");
		usernameEle = doc.createElement("username");
		passwordEle = doc.createElement("password");
		
		usernameEle.setTextContent(username);
		passwordEle.setTextContent(password);
		
		authEle.appendChild(usernameEle);
		
		authEle.appendChild(passwordEle);
		
		header = new Header(new QName("2authHeaer"), authEle);
		
		headers.add(header);
	}

}

测试类

package com.wds.java.cxf.client.user;

import java.util.List;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.wds.java.cxf.client.role.code.Entry;
import com.wds.java.cxf.client.role.code.ISecurityService;
import com.wds.java.cxf.client.role.code.MappingUserValue;
import com.wds.java.cxf.client.user.code.IUserService;

public class Main {

	@SuppressWarnings("resource")
	public static void main(String[] args) {
		ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("classpath:/conf/cxf/spring-cxf-client.xml");
		
		IUserService service = (IUserService) context.getBean("userServiceTwo");
		List userNames = service.getUserName();
		
		service = (IUserService) context.getBean("userServiceOne");
		List userNamesOne = service.getUserName();
		
		for (String string : userNames) {
			System.out.println(string);
		}
		
		for (String string : userNamesOne) {
			System.out.println(string);
		}
		
		ISecurityService  securityService = (ISecurityService) context.getBean("securityService");
		MappingUserValue userValue = securityService.getAuthority();
		List entries = userValue.getEntries();
		for (Entry entry : entries) {
			System.out.println("key=" + entry.getKey() + "    value=" + entry.getValue());
		}
	}

}

运行即可
