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

2022-01-21 07:38:10

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>

　　　　 <!-- 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

<?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

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

<!-- 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

<!-- 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。 :)
