CXF系列之和spring的结合

第一步配置MAVEN依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>4.2.3.RELEASE</version>
</dependency>
</dependencies>
</project>

第二步：编写WS接口及其实现

package demo.ws.ri;

import javax.jws.WebService;

/**
* Created by lizhaoz on 2016/4/23.
*/
@WebService
public interface HelloService {
String say(String name);
}

实现类

package demo.ws.ri;

import org.springframework.stereotype.Component;

import javax.jws.WebService;
import java.util.Set;

/**
* Created by lizhaoz on 2016/4/23.
*/
@WebService
@Component
public class HelloServiceImpl {
public String say(String name){
return "hello"+name;
}
}

需要在实现类上添加Spring的@Component注解，这样才能被IOC容器扫描到，认为它是一个SpringBean,可以根据BeanID来获取Bean实例。

第三步：配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.susn.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">
<!--Spring-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

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

所有带ws前缀的请求交给CXFServlet进行处理，也就是处理WS请求。目前主要使用了SpringIOC的特性，利用ContextLoaderListener加载Spring的配置文件。

第四步：配置Spring

配置spring.xml

<?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:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd"
>
<context:component-scan base-package="demo.ws.ri"/>
<import resource="spring-cxf.xml"/>
</beans>

第五步：配置CXF

在配置CXF中有两种配置方式

第一种配置spring-cxf.xml:

<?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://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
 http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">
<jaxws:server id="helloService" address="/soap/hello">
<jaxws:serviceBean>
<ref bean="helloServiceImpl"/>
</jaxws:serviceBean>
</jaxws:server>
</beans>

通过CSF提供的Spring命名空间发布WS，其中最重要的是addresshe jaxws:serviceBean配置的Bean。

可见，在spring中集成CXF比想象中更简单，还有一种更简单，直接使用CXF提供的endpoint方式,配置如下

<?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://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
 http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">
<!--    <jaxws:server id="helloService" address="/soap/hello">
<jaxws:serviceBean>
<ref bean="helloServiceImpl"/>
</jaxws:serviceBean>
</jaxws:server>-->
<jaxws:endpoint id="helloService" implementor="#helloServiceImpl" address="/soap/hello"/>
</beans>

这里的implementor是CXF特有的简写方式，并非是Spring的规范，通过Spring获取BeanID。这种方式也是我们推崇的方式。

第六步：部署到tomcat。

输入localhost:8080/cxf/ws即可。
