简单WEB Service接口实现(CXF与spring整合)

最近写接口，之后就对接口的简单实现做个小结：

可以在传统的JAVA EE的基础上增加一层Web Service层，这样我们的JAVA EE就可以对外暴露Web Service，这样任何平台、任何语言就可以通过程序来调用此接口了！

具体实现步骤：

1、添加CXF的相关jar包和spring的相关jar包(具体jar包根据自己的实际需求情况而定)；

commons-logging.jar

cxf.jar

neethi.jar

wsdl4j.jar

xmlschema-core.jar

spring.jar

spring-asm.jar

spring-expression.jar

2、在WEB.xml中配置CXF的核心控制器，如：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
xmlns="http://java.sun.com/xml/ns/javaee" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

  <servlet>
  <servlet-name>CXFServlet</servlet-name>
  <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
  </servlet>
  <servlet-mapping>
  <servlet-name>CXFServlet</servlet-name>
  <url-pattern>/cxf/*</url-pattern>
  </servlet-mapping>
</web-app>

3、在spring的配置文件中导入CXF提供的Schema、XML配置文件；在spring的配置文件中使用axws:endpoint元素来暴露WEB Service。具体如下

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.springframework.org/schema/beans" 
xmlns:jaxws="http://cxf.apache.org/jaxws"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://www.springframework.org/schema/beans
      http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
      http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
        http://cxf.apache.org/jaxws 
        http://cxf.apache.org/schemas/jaxws.xsd">
       
<import resource="classpath:META-INF/cxf/cxf.xml"/>
<import resource="classpath:META-INF/cxf/cxf-servlet.xml"/>
<import resource="classpath:META-INF/cxf/cxf-extension-soap.xml"/>

<jaxws:endpoint id="cxfSpringService" address="/cxfSpringService" implementorClass="com.cxf.spring.service.CXFSpringService">
<jaxws:implementor>
<bean id="cXFSpringServiceImpl" class="com.cxf.spring.service.impl.CXFSpringServiceImpl"/>
</jaxws:implementor>
</jaxws:endpoint>
</beans>

4、书写简单的WEB Service层：

接口：CXFSpringService

package com.cxf.spring.service;
import javax.jws.WebService;

@WebService
public interface CXFSpringService {

public String cxfTest1();
public void cxfTest2();
}

接口实现：CXFSpringServiceImpl

package com.cxf.spring.service.impl;
import javax.jws.WebService;
import com.cxf.spring.service.CXFSpringService;

//endpointInterface定义实现的接口，serviceName定义发布的服务名
@WebService(endpointInterface="com.cxf.spring.service.CXFSpringService",serviceName="CXFSpring")
public class CXFSpringServiceImpl implements CXFSpringService {

public String cxfTest1() {
return "CXFSpringServiceImpl";
}

public void cxfTest2() {
System.out.println("CXFSpringServiceImpl");
}
}

5、部署该WEB应用，启动tomcat，在浏览器中访问地址：http://localhost:8080/WS_cxf_Spring/cxf/cxfSpringService?wsdl。如正常出现相关的xml文件，就证明该接口正常启动：

<?xml version="1.0"?>
<wsdl:definitions xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:tns="http://service.spring.cxf.com/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:ns1="http://schemas.xmlsoap.org/soap/http" targetNamespace="http://service.spring.cxf.com/" name="CXFSpringServiceService">

到此，一个简单的WEB接口就成功编写和启动成功，就可以编写客户端来访问该接口啦！
