WebService -- Java 实现之 CXF ( 使用：Spring+CXF+Tomcat发布webService）

1. 新建一个Maven项目，选择webapp模板，命名为WS_Spring_CXF_Tomcat

2. 在POM.xml中添加Spring和CXF的依赖

<!-- 添加 Spring dependency --> <dependency>     <groupId>org.springframework</groupId>     <artifactId>spring-core</artifactId>     <version>4.1.7.RELEASE</version> </dependency> <dependency>     <groupId>org.springframework</groupId>     <artifactId>spring-beans</artifactId>     <version>4.1.7.RELEASE</version> </dependency> <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-tx</artifactId>      <version>4.1.7.RELEASE</version>     </dependency> <dependency>     <groupId>org.springframework</groupId>     <artifactId>spring-context</artifactId>     <version>4.1.7.RELEASE</version> </dependency> <dependency>     <groupId>org.springframework</groupId>     <artifactId>spring-context-support</artifactId>     <version>4.1.7.RELEASE</version> </dependency> <dependency>     <groupId>org.springframework</groupId>     <artifactId>spring-web</artifactId>     <version>4.1.7.RELEASE</version> </dependency> <dependency>     <groupId>org.springframework</groupId>     <artifactId>spring-webmvc</artifactId>     <version>4.1.7.RELEASE</version> </dependency> <dependency>     <groupId>org.springframework</groupId>     <artifactId>spring-aop</artifactId>     <version>4.1.7.RELEASE</version> </dependency> <dependency>     <groupId>org.springframework</groupId>     <artifactId>spring-aspects</artifactId>     <version>4.1.7.RELEASE</version> </dependency> <dependency>     <groupId>org.springframework</groupId>     <artifactId>spring-jdbc</artifactId>     <version>4.1.7.RELEASE</version> </dependency>   <!-- 添加CXF dependency  --> <dependency>     <groupId>org.apache.cxf</groupId>     <artifactId>cxf-core</artifactId>     <version>3.1.5</version> </dependency> <dependency>     <groupId>org.apache.cxf</groupId>     <artifactId>cxf-rt-frontend-jaxws</artifactId>     <version>3.1.5</version> </dependency> <dependency>     <groupId>org.apache.cxf</groupId>     <artifactId>cxf-rt-transports-http</artifactId>     <version>3.1.5</version> </dependency>

3. 修改 project->src->main->web app->WEB-INFO->web.xml

指定spring配置和servlet配置：

<?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" id="WebApp_ID" version="2.5">   <display-name>WS_Spring_CXF_Tomcat</display-name>   <welcome-file-list>     <welcome-file>index.html</welcome-file>     <welcome-file>index.htm</welcome-file>     <welcome-file>index.jsp</welcome-file>     <welcome-file>default.html</welcome-file>     <welcome-file>default.htm</welcome-file>     <welcome-file>default.jsp</welcome-file>   </welcome-file-list>         <!-- Spring config-->     <context-param>         <param-name>contextConfigLocation</param-name>         <param-value>classpath:applicationContext.xml</param-value>     </context-param>            <!-- Spring listener -->     <listener>         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>     </listener>     <br>　　　　 <!-- Add on a servlet to handle web service request -->     <servlet>       <servlet-name>CXFServlet</servlet-name>       <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>      </servlet>             <servlet-mapping>         <servlet-name>CXFServlet</servlet-name>         <url-pattern>/webservice/*</url-pattern>      </servlet-mapping> </web-app>

4. 添加Spring配置文件到classpath路径下

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

<?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:p="http://www.springframework.org/schema/p"      xmlns:aop="http://www.springframework.org/schema/aop"       xmlns:context="http://www.springframework.org/schema/context"      xmlns:jee="http://www.springframework.org/schema/jee"      xmlns:tx="http://www.springframework.org/schema/tx"      xmlns:jaxws="http://cxf.apache.org/jaxws"     xsi:schemaLocation="            http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd          http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd          http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd          http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-4.0.xsd          http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd         http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">                  <!-- import CXF configuration files -->     <import resource="classpath:META-INF/cxf/cxf.xml"/>     <import resource="classpath:META-INF/cxf/cxf-servlet.xml"/>

注意添加：

1.Spring和CXF名空间；

2.CXF配置文件 

5.定义WebService接口及实现类

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

package com.example.tuo.webservice.impl;   import javax.jws.WebService;   import org.springframework.stereotype.Component;   import com.example.tuo.webservice.HelloWorld;   @Component("helloWorld") @WebService public class HelloWorldImpl implements HelloWorld{       public String sayHello(String sb) {         // TODO Auto-generated method stub         return "Hello world," +sb;     }   }

在实现类中添加 "@Component("helloWorld")" 注解，并且修改Spring配置文件（applicationContext.xml），利用Spring管理实现类

?

1 2	<!-- auto scan class as bean --> <context:component-scan base-package="com.example.tuo.webservice" />

6.修改Spring配置文件,暴露微博service的endpoint

?

1 2 3 4 5

<!-- define web service provider  -->     <jaxws:endpoint         implementor="#helloWorld"         address="/HelloWorld">     </jaxws:endpoint>

7. 启动Tomcat，在浏览器中输入webservice的address

http://localhost:8080/WS_Spring_CXF_Tomcat/webservice/HelloWorld?wsdl

 

OK, 这样我们就成功的讲webservice发布到了Tomcat上。 :)
