webServer-----Spring 集成cxf笔录
目前webserver主要有俩中方式：1,传统的webserver标准集成方式-生成WSDL的xml文档. 2, 基于restful风格的webserver
java RESTful WebServer
一、概述
JAX-RS是Java提供用于开发RESTful Web服务基于注解(annotation)的API。JAX-RS旨在定义一个统一的规范，使得Java程序员可以使用一套固定的接口来开发REST应用，避免了依赖第三方框架。同时JAX-RS使用POJO编程模型和基于注解的配置并集成JAXB，可以有效缩短REST应用的开发周期。JAX-RS只定义RESTful API，具体实现由第三方提供，如Jersey、Apache CXF等。
JAX-RS包含近五十多个接口、注解和抽象类：
javax.ws.rs包含用于创建RESTful服务资源的高层次（High-level）接口和注解。
javax.ws.rs.core包含用于创建RESTful服务资源的低层次（Low-level）接口和注解。
javax.ws.rs.ext包含用于扩展JAX-RS API支持类型的APIs。
JAX-RS常用注解：
@Path：标注资源类或方法的相对路径。
@GET、@PUT、@POST、@DELETE：标注方法的HTTP请求类型。
@Produces：标注返回的MIME媒体类型。
@Consumes：标注可接受请求的MIME媒体类型。
@PathParam、@QueryParam、@HeaderParam、@CookieParam、@MatrixParam、@FormParam：标注方法的参数来自于HTTP请求的位置。@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。
spring集成cxf详解：
本次集成适用版本是cxf3.X以上版本spring3.2
<!-- CXF需要导入的jar包 -->

<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-rs-client</artifactId>
<version>${cxf.version}</version>
</dependency>
在以前2.x的CXF上，bug和配置上很复杂。3.0以后很方便，
web.xml
<!-- CXF -->
<servlet>
<servlet-name>cxf</servlet-name>
<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>cxf</servlet-name>
<url-pattern>/services/*</url-pattern>
</servlet-mapping>
spring.xml配置
<import resource="classpath:META-INF/cxf/cxf.xml" />
<import resource="classpath:META-INF/cxf/cxf-servlet.xml"/>
发布webserver 普通接口
<!-- 接口实例方式webservice接口发布 -->
<jaxws:endpoint id="WebserviceImpl" implementor="com.slwy.ticket.testcase.impl.WebserviceImpl" address="/getUser"/>
<!-- 传统方式webservice接口 -->
<bean id="departServerImpl" class="com.slwy.ticket.server.systemsetServer.impl.DepartServerImpl"></bean>
<jaxws:server id="departservice" serviceClass="com.slwy.ticket.server.systemsetServer.DepartServer" address="/departments">
<jaxws:serviceBean>
<ref bean="departServerImpl"/>
</jaxws:serviceBean>
<jaxws:inInterceptors>
<bean class="org.apache.cxf.interceptor.LoggingInInterceptor"></bean>
</jaxws:inInterceptors>
<jaxws:outInterceptors>
<bean class="org.apache.cxf.interceptor.LoggingOutInterceptor"></bean>
</jaxws:outInterceptors>
</jaxws:server>
发布webserver RestFul接口
<!-- address-请求路径 --> <jaxrs:server id="imaoPayService" address="/ipservice"> <!-- 输入拦截器设置 --> <jaxrs:inInterceptors> </jaxrs:inInterceptors> <!-- 输出拦截器设置 --> <jaxrs:outInterceptors> </jaxrs:outInterceptors> <!-- serviceBeans-暴露的WebService服务类 --> <jaxrs:serviceBeans> <ref bean="regUser" /> </jaxrs:serviceBeans> <!-- 支持的协议 --> <jaxrs:extensionMappings> <entry key="json" value="application/json" /> <entry key="xml" value="application/xml" /> </jaxrs:extensionMappings> <!-- json支持格式 -->
<jaxrs:providers>
<bean class="com.fasterxml.jackson.jaxrs.json.JacksonJsonProvider"/>
</jaxrs:providers>
<!-- 编码格式 --> <jaxrs:languageMappings> <entry key="en" value="en-gb"/> </jaxrs:languageMappings> </jaxrs:server> 总结如下：
@POST 表示HTTP的访问模式
@Path 表示访问路径
@Produces({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON}) 响应内容 MIME 类型
jaxws:endpoint（cxf风格）是定义的一个soap WebService，另一种jaxws:server标签（xfire风格，因为Apache CXF = Celtix + XFire ，是XFire的演进版）可以用。
我通过设置jsonProvider使其能够在response的时候返回一个json格式的数据：
|
|
<bean id="jsonProvider" class="org.codehaus.jackson.jaxrs.JacksonJsonProvider"></bean> <jaxrs:providers> <ref bean="jsonProvider"/> </jaxrs:providers> |
