webservice+restful+cxf（服务端客户端调用）

摘要: 经过漫长的时间周期，终于完成了，restful风格的webservice开发工作，在这里记录一下学习过程以及新的体会

1.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>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>CXFServlet</servlet-name>
<url-pattern>/ws/*</url-pattern>
</servlet-mapping>

2.rest.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:jaxrs="http://cxf.apache.org/jaxrs"
xmlns:cxf="http://cxf.apache.org/core"
xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://cxf.apache.org/jaxrs http://cxf.apache.org/schemas/jaxrs.xsd http://cxf.apache.org/core http://cxf.apache.org/schemas/core.xsd">
<import resource="classpath:META-INF/cxf/cxf.xml" />
<import resource="classpath:META-INF/cxf/cxf-extension-jaxrs-binding.xml" />
<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
<jaxrs:server id="restServiceContainer" address="/rest">
<jaxrs:serviceBeans>
<ref bean="restSample" />
<ref bean="restVuln" />
</jaxrs:serviceBeans>
<jaxrs:extensionMappings>
<entry key="json" value="application/json" />
<entry key="xml" value="application/xml" />
</jaxrs:extensionMappings>
<jaxrs:languageMappings>
<entry key="en" value="en-gb" />
</jaxrs:languageMappings>
</jaxrs:server>
</beans>

3.java

@Path(value = "/sample")
public interface RESTSample {
@GET
@Produces(MediaType.TEXT_PLAIN)
@Path("/test/{param}")
public String doRequestTest(@PathParam("param") String param,
@Context HttpServletRequest servletRequest, @Context HttpServletResponse servletResponse);

4.直接访问路径 其中ws是web.xml中的配置，rest是rest.xml文件中的配置，demo是项目path路径

（1）直接显示发布接口

http://192.168.28.101:8080/project/ws



（2）直接访问资源，直接得到 demo资源下list的数据并且用xml格式返回

http://192.168.28.101:8080/project7.0/ws/rest/demo/list?_type=xml //同样可以使用_type=json返回数据



5.上边都是服务端发布，接下来是客户端调用

private static WebClient client;

@Before
public void init() {
// 手动创建webClient对象，注意这里的地址是发布的那个/rest地址
String url = "http://192.168.28.101:8080/project/ws/rest/";
client = WebClient.create(url);
// 从Spring Ioc容器中拿webClient对象
//        ApplicationContext ctx = new ClassPathXmlApplicationContext("WEB-INF/applicationContext-client.xml");
//        client = (WebClient) ctx.getBean("webClient", WebClient.class);
}
@After
public void destory(){
}

//自己�??发的
@Test
public void testGet() {
try {
System.out.println(client.path("sample").accept(MediaType.TEXT_PLAIN).get(String.class));
} catch (Exception e) {
e.printStackTrace();
}
}

@Test
public void testRequest() {
System.out.println(client.path("sample/request/234234").accept(MediaType.TEXT_PLAIN).get(String.class));
}

@Test
public void testBean() {
User user = client.path("sample/bean/{id}", 25).accept(MediaType.APPLICATION_XML).get(User.class);
System.out.println(user);
}

@Test
public void testList() {
System.out.println("--------------"+client.path("sample/list").accept(MediaType.APPLICATION_XML).get(Users.class).getUsers());
}

6.针对返回json数据显示格式调整

<bean id="jsonProvider" class="org.apache.cxf.jaxrs.provider.json.JSONProvider">
<property name="serializeAsArray" value="true" />
<property name="arrayKeys" ref="jsonKeys" />
<property name="produceMediaTypes" ref="jsonTypes" />
<property name="consumeMediaTypes" ref="jsonTypes" />
<property name="ignoreNamespaces" value="true" />
<property name="dropRootElement" value="true" />
<property name="ignoreMixedContent" value="true" />
<property name="supportUnwrapped" value="true" />
<property name="attributesToElements" value="true" />
</bean>

7.针对restful拦截器使用

<jaxrs:server id="rest_HelloWorld" address="/">
<jaxrs:inInterceptors>
<ref bean="inMessageInterceptor"/>
</jaxrs:inInterceptors>
<jaxrs:outInterceptors>
<ref bean="outMessageInterceptor"/>
</jaxrs:outInterceptors>
<jaxrs:serviceBeans>
<ref bean="rest_HelloWorldImpl" />
</jaxrs:serviceBeans>
<jaxrs:extensionMappings>
<entry key="json" value="application/json" />
<entry key="xml" value="application/xml" />
</jaxrs:extensionMappings>
<jaxrs:languageMappings>
<entry key="en" value="en-gb" />
</jaxrs:languageMappings>
</jaxrs:server>
