(七)CXF之与spring整合发布web服务

一、需求分析

  • 用spring发布服务

二、案例

  2.1  引入maven依赖

<dependencies>
<!-- 添加Spring支持 -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>4.3.12.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>4.3.12.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-tx</artifactId>
<version>4.3.12.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>4.3.12.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
<version>4.3.12.RELEASE</version>
</dependency> <dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>4.3.12.RELEASE</version>
</dependency> <dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>4.3.12.RELEASE</version>
</dependency> <dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aop</artifactId>
<version>4.3.12.RELEASE</version>
</dependency> <dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aspects</artifactId>
<version>4.3.12.RELEASE</version>
</dependency> <dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>4.3.12.RELEASE</version>
</dependency> <!-- 添加cxf支持 -->
<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> <dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>4.0.0</version>
<scope>provided</scope>
</dependency>
</dependencies>

  2.2  配置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"
id="WebApp_ID" version="2.5"> <!-- Spring配置文件 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param> <!-- Spring监听器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener> <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>

  2.3  编写服务接口

package com.shyroke.service;

import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService; @WebService
public interface IFirst {
@WebResult(name = "addResult")
public int add(@WebParam(name = "x") int x, @WebParam(name = "y") int y);
}

  2.4  编写服务接口实现类

package com.shyroke.service;

import java.util.Date;

import javax.jws.WebService;

import org.springframework.stereotype.Component;

import javafx.scene.chart.PieChart.Data;

@Component("firstService")
@WebService(endpointInterface="com.shyroke.service.IFirst")
public class First implements IFirst {
public int add(int x, int y) {
return x+y;
}
}
  • 配置    applicationContext.xml
<?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 resource="classpath:META-INF/cxf/cxf.xml" />
<import resource="classpath:META-INF/cxf/cxf-servlet.xml" /> <!-- 自动扫描 -->
<context:component-scan base-package="com.shyroke.service" /> <jaxws:endpoint implementor="#firstService" address="/first">
</jaxws:endpoint>
</beans>
  • 要引入 xmlns:jaxws="http://cxf.apache.org/jaxws"  才能使用 <jaxws:endpoint> 标签,浏览器通过url=“/webservice/first?wsdl”访问web服务对应的wsdl文件
  • implementor的值是服务接口类的实现类,且"#firstService"要加#,表示从spring容器中取得一个bean叫firstService的bean
  • 启动jetty
