JSP学习笔记(九十二):整合spring与cxf,利用cxf编写webservice
一、下载cxf
下载地址:http://cxf.apache.org/download.html
我下载的是最新版的cxf 2.1.3
二、准备工作:在spring环境下使用cxf
1.下载完cxf的包后,至少需要添加如下包,才能正常使用cxf(我一个一个试的,很郁闷,居然要那么多,下载的包里都有):
commons-logging-1.1.1.jar
geronimo-activation_1.1_spec-1.0.2.jar
geronimo-annotation_1.0_spec-1.1.1.jar
geronimo-ws-metadata_2.0_spec-1.1.2.jar
geronimo-stax-api_1.0_spec-1.0.1.jar
geronimo-jaxws_2.1_spec-1.0.jar
jaxb-api-2.1.jar
jaxb-impl-2.1.7.jar
saaj-api-1.3.jar
wstx-asl-3.2.6.jar
wsdl4j-1.6.2.jar
XmlSchema-1.4.2.jar
xml-resolver-1.2.jar
2.添加如下内容到web.xml
<servlet>
<servlet-name>CXFServlet</servlet-name>
<display-name>CXF Servlet</display-name>
<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
<load-on-startup>3</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>CXFServlet</servlet-name>
<url-pattern>/services/*</url-pattern>
</servlet-mapping>
3.在spring配置文件中,修改文件内容为:
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">
<import resource="classpath:META-INF/cxf/cxf.xml" />
<import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" />
<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
添加的内容有三部分:
①xmlns:jaxws="http://cxf.apache.org/jaxws"
②http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd
③ <import resource="classpath:META-INF/cxf/cxf.xml" />
<import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" />
<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
可以在原有配置文件上修改
三、开始使用:编写服务端WebService
1.添加一个接口,Hello.java:
import javax.jws.WebService;
@WebService
public interface Hello {
public String say(String text);
}
2.实现这个接口,HelloImpl.java:
import javax.jws.WebService;
import com.ruiri.webservice.Hello;
@WebService(endpointInterface = "com.test.webservice.Hello")
public class HelloImpl implements Hello {
public String say(String text) {
System.out.println(text);
return "Hello," + text;
}
}
跟平时使用的接口和类一样,只是添加了对应的注解
3.在spring的配置文件添加如下内容:
address="/HelloWorld" />
这样,服务端的WebService就做好了,在浏览器可以通过 http://站点/services/ 看到可见的service
四、编写客户端WebService
1.编写一个接口,这里还使用先前写的Hello.java
2.在spring的配置文件添加如下内容:
address="http://站点/services/HelloWorld" />
3.在代码用调用这个bean:
WebApplicationContext ac = WebApplicationContextUtils.getRequiredWebApplicationContext(sc);
Hello hello = (Hello) ac.getBean("helloClient");
String str = hello.say("zhang");
这样,客户端调用的代码也有了,配置稍微有些麻烦,配置完后,使用倒是很简单。
