CXF_Spring_Rest

一、接口类

<PRE class=java name="code">@Path("/rest_HelloWorld")
public interface Rest_HelloWorld {
@GET
@Produces (MediaType.TEXT_PLAIN)
@Path("/say/{name}")
public String say(@PathParam("name")String name); @GET
@Produces (MediaType.TEXT_PLAIN)
@Path("/sayHello/{name}")
public String sayHello(@PathParam("user")User user); @GET
@Produces ({MediaType.APPLICATION_JSON,MediaType.APPLICATION_XML})
@Path("/getList/{id}")
public List<User> getList(@PathParam("id")Long id); }</PRE>
 

(1)、@Path,标注资源类或方法的相对路径

(2)、@GET,@PUT,@POST,@DELETE,标注方法是用的HTTP请求的类型

  GET 列出资源集合的所有成员。
  PUT 使用一个集合更新(替换)另一个集合。
  POST 在集合中创建数字资源, 
  DELETE 删除整个资源集合。

(3)、@Produces,标注返回的MIME媒体类型,( 注解标注,这个注解可以包含一组字符串,默认值是*/*,它指定REST 服务的响应结果的MIME 类型,例如:application/xml、application/json、image/jpeg 等),你也可以同时返回多种类型,但具体生成结果时使用哪种格式取决于ContentType。

CXF 默认返回的是JSON 字符串。

(4)、@PathParam,@QueryParam,@HeaderParam,@CookieParam,@MatrixParam,@FormParam,分别标注方法的参数来自于HTTP请求的不同位置,例如@PathParam来自于URL的路径,@QueryParam来自于URL的查询参数,@HeaderParam来自于HTTP请求的头信息,@CookieParam来自于HTTP请求的Cookie。

2、接口实现类

@Service("rest_HelloWorldImpl")
public class Rest_HelloWorldImpl implements Rest_HelloWorld { public String say(String name) {
return name+",您好!";
} public String sayHello(User user) {
return user.getName()+",您好!";
} public List<User> getList(Long id){
List<User> list = new ArrayList<User>(); Long sid=1L;
User user = new User(sid,"张三"+sid,21);
list.add(user); sid=2L;
user = new User(sid,"张三"+sid,21);
list.add(user); sid=3L;
user = new User(sid,"张三"+sid,21);
list.add(user);
return list;
}
}

3、CXF在Spring中的配置

<?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"
xmlns:jaxrs="http://cxf.apache.org/jaxrs"
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
http://cxf.apache.org/jaxrs http://cxf.apache.org/schemas/jaxrs.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" /> <bean id="inMessageInterceptor" class="org.apache.cxf.interceptor.LoggingInInterceptor" />
<bean id="outMessageInterceptor" class="org.apache.cxf.interceptor.LoggingOutInterceptor"/> <!--id:名称(随意配),implementor:指定接口具体实现类,address:随意配-->
<jaxws:endpoint id="helloWorld" implementor="#HelloWorldImpl" address="/HelloWorld" >
<!-- 输入日志拦截器 -->
<jaxws:inInterceptors>
<ref bean="inMessageInterceptor"/>
</jaxws:inInterceptors>
<!-- 输出日志拦截器 -->
<jaxws:outInterceptors>
<ref bean="outMessageInterceptor"/>
</jaxws:outInterceptors>
<jaxws:properties>
<entry key="mtom_enabled" value="true"></entry>
</jaxws:properties>
</jaxws:endpoint> <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> <!-- WebService 客户端 spring 配置文件cxf与Spring集成,cxf里提供了一个工厂类org.apache.cxf.jaxws.JaxWsProxyFactoryBean,
可以方便实现的调用WebService。serviceClass属性是接口类,address是webService的路径在其他bean里如果要调用webservice,
只要将client这个bean注入到需要使用的bean里。-->
<bean id="client" class="com.exp.service.outer.HelloWorld" factory-bean="clientFactory" factory-method="create" />
<bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">
<property name="serviceClass" value="com.exp.service.outer.HelloWorld" />
<property name="address" value="http://localhost:8080/demo/webservice/HelloWorld" />
</bean>
</beans>

  

4、访问

http://localhost:8080/demo/webservice/rest_HelloWorld/getList/1

返回JSON格式: http://localhost:8080/demo/webservice/rest_HelloWorld/getList/1?_type=json

返回XML格式: http://localhost:8080/demo/webservice/rest_HelloWorld/getList/1?_type=xml
