cxf+spring实现webservice

1、构建maven项目，工程结构如下：

这里需要特别指出就是cxf-core-3.1.12.jar类路径META-INF/cxf下有一个cxf.xml的配置文件，这个在applicationContext.xml配置文件中会使用到。

2、编写pom.xml文件,这里需要引入cxf-rt-frontend-jaxws,cxf-rt-transports-http两个jar，因为要和spring整合，这里还需要引入spring的依赖。下面的pom文件已经是最精简的。

<properties>
<cxf.version>3.1.12</cxf.version>
<spring.version>4.2.0.RELEASE</spring.version>
</properties>
<dependencies>
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-frontend-jaxws</artifactId>
<version>${cxf.version}</version>
</dependency>
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-transports-http</artifactId>
<version>${cxf.version}</version>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>${spring.version}</version>
</dependency>
</dependencies>

3、接口和实现类:自定义一个webservice接口BaseService并开启注解,自定义BusinessService类实现BaseService接口。

BaseService.java

package com.xxx.service;

import javax.jws.WebService;

@WebService
public interface BaseService {
public int add(int a,int b);
public String sayHello(String name);
}

BusinessService.java

package com.xxx.service.impl;

import javax.jws.WebService;

import com.xxx.service.BaseService;
@WebService(endpointInterface="com.xxx.service.BaseService")
public class BusinessService implements BaseService {

@Override
public int add(int a, int b) {
return a+b;
}

@Override
public String sayHello(String name) {
return "hello,"+name;
}

}

4、web.xml配置文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
<display-name>webservice</display-name>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath: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>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>CXFServlet</servlet-name>
<url-pattern>/webservice/*</url-pattern>
</servlet-mapping>
</web-app>

5、applicationContext.xml,这里需要指出的是在创建applicationContext.xml之后，在命名空间中引入jaxws,文件中需要引入一个cxf.xml文件，这个文件无需手动创建，他在cxf-core-3.1.12.jar类路径下的META-INF/cfx下。在第一步的项目结构中可以看到。

<?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:jaxws="http://cxf.apache.org/jaxws"
xsi:schemaLocation="http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> 
<!-- 该文件是在cxf-core-3.1.12.jar的类路径下的META-INF/cxf/cxf.xml -->
<import resource="classpath:META-INF/
b23b
cxf/cxf.xml"/>
<bean id="business" class="com.xxx.service.impl.BusinessService"></bean>
<jaxws:endpoint id="businessService" address="/business" implementor="#business"></jaxws:endpoint>
</beans>

6、接口发布
