（原创）Maven+Spring+CXF+Tomcat7 简单例子实现webservice

这个例子需要建三个Maven项目，其中一个为父项目，另外两个为子项目

首先，建立父项目testParent，选择quickstart：

输入项目名称和模块名称，然后创建：

然后建立子项目testInterface：

再建立子项目projectImpl，过程跟上面以上，只是类型要选webapp（到时候启动工程或者打包都是以这个项目为主的）：

建好之后，在testParent的pom.xml里面写入下面内容，主要是加入了cxf，junit，logback，springframework的依赖，在父项目加入依赖，子项目就不需要再加入依赖了：

        </dependency>
  </dependencies>
  <modules>
      <module>testInterface</module>
      <module>projectImpl</module>
  </modules>
</project>

然后在testInterface的src/main/java下面新建类

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;

@Path("/a")
public interface TestIn1 {

    @GET
    @Path("/doGet/{first}/{last}")
    @Produces(MediaType.APPLICATION_XML)
    public String doGet(@PathParam(value="first") String firstName,@PathParam(value="last") String lastName);

    @POST
    @Path("/itemComfirm")
    @Produces(MediaType.APPLICATION_XML)
    public String itemComfirm(String xmlParam,@Context HttpServletRequest req,@Context HttpServletResponse res);
}

然后在projectImpl的pom.xml修改，这里加入对testInterface子项目的依赖：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>testParent</groupId>
    <artifactId>testParent</artifactId>
    <version>0.0.1-SNAPSHOT</version>
  </parent>
  <artifactId>projectImpl</artifactId>
  <packaging>war</packaging>

  <dependencies>
      <dependency>
          <groupId>testParent</groupId>
          <artifactId>testInterface</artifactId>
          <version>122</version>
          <type>jar</type>
          <scope>compile</scope>
      </dependency>
  </dependencies>
</project>

然后在projectImpl的src/main/java下面新建类，并且实现testInterface子项目中的TestIn1接口：

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class TestIn1Impl implements TestIn1 {

    public String doGet(String firstName, String lastName) {

        return "hihihihi"+","+firstName+","+lastName;
    }

    public String itemComfirm(String xmlParam, HttpServletRequest req, HttpServletResponse res) {

        return "hahahaha"+","+xmlParam;
    }

}

再然后在下图路径修改application.xml和web.xml，没有文件的话就自己新建：

application.xml：

jaxrs:extensionMappings和jaxrs:languageMappings表示可根据URL后缀不同来进行不同的配置，例如/testURL.xml，那么该请求的请求头就会设置为application/xml，为/testURL.en，则会用en-gb来解析请求内容。详情可参考：http://cxf.apache.org/docs/jax-rs.html

    <jaxrs:server id="TestIn1ImplServiceContainer">
        <jaxrs:serviceBeans>
            <ref bean="TestIn1Impl" />
        </jaxrs:serviceBeans>  

        <jaxrs:extensionMappings>
            <entry key="xml" value="application/xml" />
        </jaxrs:extensionMappings>

            <entry key="en" value="en-gb"/>
        </jaxrs:languageMappings>
    </jaxrs:server>  

</beans> 

web.xml：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

        <param-name>contextConfigLocation</param-name>
        <param-value>classpath*:application.xml</param-value>
    </context-param>  

    <!-- spring context listener -->
    <listener>
        <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
    </listener>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>  

    <!-- 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>/testParent/*</url-pattern>
    </servlet-mapping>  

</web-app>

然后再写一个测试类：

import javax.ws.rs.core.MediaType;

import org.apache.cxf.jaxrs.client.WebClient;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;

public class TestClient1 {

    private WebClient client;
    private String url="http://localhost:8080/testParent/testParent/a";

    @Before
    public void setUp() throws Exception{
        System.out.println("setupbegan");
        client=WebClient.create(url).header("charset", "UTF-8").encoding("UTF-8").acceptEncoding("UTF-8");
    }

    @After
    public void tearDown() throws Exception{
        System.out.println("tearDownbegan");
        client=null;
    }

    @Test
    public void testItemConfirm(){
        System.out.println("began");
        String xmlaaParam="<a>ddd</a>";
        String responseMsg=client.path("itemComfirm").accept(MediaType.APPLICATION_XML).post(xmlaaParam,String.class);
        System.out.println("response :"+responseMsg);
        System.out.println("end");
    }

    @Test
     public void testDoGet() {
          System.out.println("began");
        String responseString = client.path("doGet/"+"dsdsd"+"/"+"uyuy"+"")
                                    .accept(MediaType.APPLICATION_XML)
                                    .get(String.class);
        System.out.println("response :"+responseString);
        System.out.println("end");
    }

}

最后，在Eclipse的sever插件中加入ProjetImpl项目，然后启动项目：

启动成功之后，执行测试类，控制台输出：

setupbegan
began
response :hihihihi,dsdsd,uyuy
end
tearDownbegan
setupbegan
began
response :hahahaha,<a>ddd</a>
end
tearDownbegan

如有错误，欢迎指出。
