CXF开发及与Spring整合开发

前言

本篇承接上一篇

Java CXF介绍与实例

开发环境：

Java: 1.8.0_161

Eclipse Version: Oxygen.3 Release (4.7.3)

Maven: 3.5.3

Tomcat：7.0

工程开发环境与框架搭建

1. 使用maven创建web 项目

mvn archetype:generate -DgroupId=com.oscar999 -DartifactId=WebStudy -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false

2. 切换到产生的项目路径，将此项目切换为eclipse的web项目

mvn eclipse:eclipse -Dwtpversion=2.0

注：这里直接使用wtpversion=4.0会有问题，所以先用2.0, 后面再修改。

这个设定和Tomcat的版本是对应的：

dynamic web module 2.4 对应Tomcat 5.5
dynamic web module 2.5 对应Tomcat 6.0
dynamic web module 3.0 对应Tomcat 7.0

3. 打开eclipse, 将此项目导入。

4. 修改wtpversion

有两种方式：

一种是在eclipse界面操作。工程上右键单击，找到Project Facets, 可以设定Dynamic Web Module和Java的版本

另一种是通过修改eclipse 文件。项目路径.settings 的org.eclipse.wst.common.project.facet.core.xml
<installed facet="jst.java" version="1.8"/>

5. 添加服务器到eclipse

windows->Preferences--> Server-->Runtime Environment, 加入Tomcat 7

6. 在pom.xml加入cxf依赖项

<dependency><groupId>org.apache.cxf</groupId><artifactId>cxf</artifactId><version>3.2.4</version><type>pom</type></dependency><dependency><groupId>org.apache.cxf</groupId><artifactId>cxf-rt-frontend-jaxws</artifactId><version>3.2.4</version></dependency><dependency><groupId>org.apache.cxf</groupId><artifactId>cxf-rt-transports-http</artifactId><version>3.2.4</version></dependency><dependency><groupId>org.codehaus.woodstox</groupId><artifactId>stax2-api</artifactId><version>4.1</version></dependency><dependency><groupId>org.codehaus.woodstox</groupId><artifactId>woodstox-core-asl</artifactId><version>4.4.1</version></dependency><dependency><groupId>org.apache.cxf</groupId><artifactId>cxf-rt-frontend-simple</artifactId><version>3.2.4</version></dependency>

7. 需要Servlet API

     <dependency><groupId>javax.servlet</groupId><artifactId>javax.servlet-api</artifactId><version>4.0.1</version><scope>provided</scope></dependency>

不整合Spring 的方式

1. 接口与实现类

MyWebServiceI 和MyWebServiceImpl沿用上一篇的就可以了。

2. 定义Servlet

/*** @Title: CxfPublishServlet.java* @Package com.oscar999* @Description: TODO* @author oscar999* @date May 23, 2018 4:22:51 PM* @version V1.0*/package com.oscar999;import javax.servlet.ServletConfig;import org.apache.cxf.Bus;
import org.apache.cxf.BusFactory;
import org.apache.cxf.transport.servlet.CXFNonSpringServlet;
import  org.apache.cxf.frontend.*;/*** @ClassName: CxfPublishServlet* @Description: TODO* @author oscar999*/public class CxfPublishServlet extends CXFNonSpringServlet {@Overridepublic void loadBus(ServletConfig sc) {super.loadBus(sc);Bus bus = getBus();BusFactory.setDefaultBus(bus);// Endpoint.publish("/sayHi",new MyWebServiceImpl());MyWebServiceImpl hi = new MyWebServiceImpl();ServerFactoryBean sfb = new ServerFactoryBean(); // serversfb.setServiceClass(MyWebServiceI.class);//sfb.setAddress("/myweb"); //sfb.setServiceBean(hi);sfb.create();}
}

3. 在web.xml 新增Servlet的配置

 <servlet><description>publsh web serivces</description><display-name>CxfPublishServlet</display-name><servlet-name>CxfPublishServlet</servlet-name><servlet-class>com.oscar999.CxfPublishServlet</servlet-class><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>CxfPublishServlet</servlet-name><url-pattern>/webservice/*</url-pattern></servlet-mapping>

4. Run as -> Run on Server , 访问如下地址：

http://localhost:8080/WebStudy/webservice/myweb?wsdl

整合Spring的方式

这里新进一个新的web Project: webPrj

1. 新建Project

mvn archetype:generate -DgroupId=com.oscar999 -DartifactId=webPrj -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false

2. eclipse设置和依赖项导入和上面类似。

3.导入Spring 依赖项

<!--Spring --><dependency><groupId>org.springframework</groupId><artifactId>spring-core</artifactId><version>4.3.17.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-beans</artifactId><version>4.3.17.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-tx</artifactId><version>4.3.17.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>4.3.17.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context-support</artifactId><version>4.3.17.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-web</artifactId><version>4.3.17.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>4.3.17.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-aop</artifactId><version>4.3.17.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-aspects</artifactId><version>4.3.17.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>4.3.17.RELEASE</version></dependency>

接下来，开始代码和配置部分

1. 接口

/*** @Title: MyWebServiceI.java* @Package com.oscar999* @Description: TODO* @author oscar999* @date May 23, 2018 11:34:39 AM* @version V1.0*/package com.oscar999;import javax.jws.WebParam;
import javax.jws.WebService;/*** @ClassName: MyWebServiceI* @Description: TODO* @author oscar999*/@WebService
public interface MyWebServiceI {String sayHi(@WebParam(name = "text") String text);
}

2.实现类

/*** @Title: MyWebServiceImpl.java* @Package com.oscar999* @Description: TODO* @author oscar999* @date May 23, 2018 11:37:02 AM* @version V1.0*/package com.oscar999;import javax.jws.WebParam;
import javax.jws.WebService;/*** @ClassName: MyWebServiceImpl* @Description: TODO* @author oscar999*/public class MyWebServiceImpl implements MyWebServiceI {public String sayHi(@WebParam(name = "text") String text) {return "Hello," + text;}
}

3. Spring配置文件

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:jaxws="http://cxf.apache.org/jaxws"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd"><bean id="myWebService" class="com.oscar999.MyWebServiceImpl"></bean><jaxws:server address="/myService"serviceClass="com.oscar999.MyWebServiceI"><jaxws:serviceBean><ref bean="myWebService" /></jaxws:serviceBean></jaxws:server>
</beans>

4. 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"xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"version="3.0"><display-name>Archetype Created Web Application</display-name><servlet><servlet-name>cxfServlet</servlet-name><servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class><load-on-startup>0</load-on-startup></servlet><servlet-mapping><servlet-name>cxfServlet</servlet-name><url-pattern>/ws/*</url-pattern></servlet-mapping><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml</param-value></context-param>
</web-app>

5. 访问WSDl

http://localhost:8080/webPrj/ws/myService?wsdl

问题及解决

1. jar 包没有copy 到eclipse
进入到tomcat的部署路径.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\下检查了一下，发现工程部署后在WEB-INF文件夹下没有生成lib目录，正常情况下，会生成lib目录并把工程的所有依赖jar包都部署到该目录下。
解决方法：
右键点击项目--选择Properties
选择Deployment Assembly,在右边点击Add按钮，在弹出的窗口中选择Java Build Path Entries
