Cxf 2.5.2 + spring 开发配置
http://cxf.apache.org/docs/writing-a-service-with-spring.html
- Set up your build for CXF
- Writing a simple JAX-WS service
- Set up the HTTP transport
第一步：设置你的cxf的classpath
1、依赖库
commons-logging-1.1.1.jar geronimo-activation_1.1_spec-1.0-M1.jar (or Sun's Activation jar) geronimo-annotation_1.0_spec-1.1.jar (JSR 250) geronimo-javamail_1.4_spec-1.7.1.jar (or Sun's JavaMail jar) geronimo-servlet_3.0_spec-1.0.jar (or Sun's Servlet jar) geronimo-ws-metadata_2.0_spec-1.1.1.jar (JSR 181) jaxb-api-2.1.jar jaxb-impl-2.1.13.jar jaxws-api-2.1.jar neethi-3.0.0.jar saaj-api-1.3.jar saaj-impl-1.3.jar stax-api-1.0.1.jar stax2-api-3.1.1.jar wsdl4j-1.6.2.jar woodstox-core-asl-4.0.8.jar xmlschema-core-2.0.jar xml-resolver-1.2.jar
2、The Spring jars:
aopalliance-1.0.jar spring-core-3.0.5.RELEASE.jar spring-beans-3.0.5.RELEASE.jar spring-context-3.0.5.RELEASE.jar spring-web-3.0.5.RELEASE.jar
3、And the CXF jar:
cxf-2.4.0.jar
第二步 编写你的service
1、代码编写
接口：
package demo.spring.service;
import javax.jws.WebService;
@WebService
public interface HelloWorld {
String sayHi(String text);
}
接口实现：
package demo.spring.service;
import javax.jws.WebService;
@WebService(endpointInterface = "demo.spring.service.HelloWorld")
public class HelloWorldImpl implements HelloWorld {
public String sayHi(String text) {
System.out.println("sayHi called");
return "Hello " + text;
}
}
2、spring文件配置
Lets create a "cxf-servlet.xml" file in our WEB-INF directory which declares an endpoint bean。cxf-servlet.xml默认在WEB-INF directory但是可以在web.xml里面指定地址。
<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">
<import resource="classpath:META-INF/cxf/cxf.xml" />
<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
<jaxws:endpoint
id="helloWorld"
implementor="demo.spring.service.HelloWorldImpl"
address="/HelloWorld" />
</beans>
另外的配置方式
If you want to reference a spring managed-bean, you can write like this:
<bean id="hello" class="demo.spring.HelloWorldImpl" />
<jaxws:endpoint id="helloWorld" implementor="#hello" address="/HelloWorld" />
The bean uses the following properties:
- id specifies the id of the bean in the Spring context.
- implementor specifies the implementation class.
- address specifies the location the service will be hosted. This should just be a related path. This is because CXF can't know the war name and the servlet container's listening port, CXF will update the endpoint address with the request url at the runtime.
To provide a bean name instead of a classname as an implementor, simply supply the bean-name prepended with "#", e.g. implementor="#myBean".
You can also do more sophisticated things with the <jaxws:endpoint> element like add nested tags to attach JAX-WS Handlers or CXF Interceptors to the service. For more on this see JAX-WS Configuration.
第三步设置cxf的servlet
Since we're relying on the default "cxf-servlet.xml" file the default web.xml referenced by many samples can be used.
Alternatively, for arbitrarily named configuration files such as beans.xml, application-context.xml, etc. we can add the following elements:
- the Spring ContextLoaderLister. This starts Spring and explicitly loads the configuration file. We can specify where our file is via a context-param element.
An example:
<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>/*</url-pattern> </servlet-mapping>
It is important to note that the address that you chose for your endpoint bean must be one your servlet listens on. For instance, if my Servlet was register for "/some-services/*" but my address was "/more-services/HelloWorld", there is no way CXF could receive a request.
Create a Client (Easy Way)
Just like the <jaxws:endpoint> used on the server side, there is a <jaxws:client> that can be used on the client side. You'll give it a bean name, the service interface, and the service URL, and it will create a bean with the specified name, implementing the service interface, and invoking the remote SOAP service under the covers:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:jaxws="http://cxf.apache.org/jaxws"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
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:client id="helloClient"
serviceClass="demo.spring.HelloWorld"
address="http://localhost:9002/HelloWorld" />
</beans>
You can now inject that "helloClient" bean into any other Spring bean, or look it up from the Spring application context manually with code like this:
ApplicationContext context = ...; // your Spring ApplicationContext
HellWorld client = (HelloWorld) context.getBean("helloClient");
You can also do more sophisticated things with the <jaxws:client> element like add nested tags to attach JAX-WS Handlers or CXF Interceptors to the client. For more on this see JAX-WS Configuration.
Create a Client (More Manual Way)
CXF includes a JaxWsProxyFactory bean which create a client for you from your service interface. You simply need to tell it what your service class is (the HelloWorld interface in this case) and the URL of your service. You can then create a client bean via the JaxWsProxyFactory bean by calling it's create() method.
Here's an example:
<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/schema/jaxws.xsd">
<bean id="client" class="demo.spring.service.HelloWorld"
factory-bean="clientFactory" factory-method="create"/>
<bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">
<property name="serviceClass" value="demo.spring.service.HelloWorld"/>
<property name="address" value="http://localhost:9002/services/HelloWorld"/>
</bean>
</beans>
If you were going to access your client you could now simply pull it out of the Spring context (or better yet, inject it into your application using Spring!):
ApplicationContext context = ...; // your Spring ApplicationContext
HelloWorld client = (HelloWorld) context.getBean("client");
