利用webservice跟jms实现系统间的数据同步之一
利用webservice和jms实现系统间的数据同步之一
要实现的功能就是:jmsserver系统从webserviceserver系统中通过webservice获取数据,jmsserver系统并把获取到的数据保存到数据库,最后,jmsserver系统再通过jms把这些数据发送到jmsclient系统,jmsclient系统接收jms消息并在控制台打印,完毕。
所用到的技术:srping、cxf、jms、atomikos、hibernate,其中cxf实现webservice、restfulservice,atomikos用于实现数据库和jms的分布式事务,spring用于集成cxf、jms、atomikos、hibernate,完毕。小弟初步学习此技术,此文章肯定存在许多不足之处,还请各位能够指教!
首先说明webserviceserver系统,结构图如下:
其中UserService用于实现webservice,内容如下:
package com.test; import java.util.List; import javax.jws.WebResult; import javax.jws.WebService; @WebService public interface UserService { @WebResult List<User> getUserList(); User getUserStr(); }
UserServiceImpl实现webservice,内容如下:
package com.test; import java.util.ArrayList; import java.util.List; public class UserServiceImpl implements UserService { public List<User> getUserList() { List<User> users = new ArrayList<User>(); users.add(new User((long)1, "zhangsan1", 100)); users.add(new User((long)2, "zhangsan2", 200)); return users; } public User getUserStr() { return new User((long)3, "lisi1", 300); } }
其中RestfulService用于实现restfulwebservice,内容如下:
package com.test.restful; import javax.ws.rs.Consumes; import javax.ws.rs.GET; import javax.ws.rs.Path; import javax.ws.rs.PathParam; public interface RestfulService { @GET @Path("/{name}") @Consumes({"application/json"}) public String getUserByName(@PathParam("name") String name); }
RestfulServiceImpl实现RestfulService,内容如下:
package com.test.restful; import com.test.User; public class RestfulServiceImpl implements RestfulService { public String getUserByName(String name) { return new User((long)4, name, 20).toString(); } }
web.xml配置如下:
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:application-*.xml</param-value> </context-param> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> <!-- 用于实现webservice --> <servlet> <servlet-name>CXFService</servlet-name> <servlet-class> org.apache.cxf.transport.servlet.CXFServlet </servlet-class> <load-on-startup>1</load-on-startup> </servlet> <!-- url-pattern说明我们通过cxf发布的webservice和restful都位于service的路径下 --> <servlet-mapping> <servlet-name>CXFService</servlet-name> <url-pattern>/service/*</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
spring配置文件如下:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:jaxws="http://cxf.apache.org/jaxws" xmlns:jaxrs="http://cxf.apache.org/jaxrs" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd http://cxf.apache.org/jaxrs http://cxf.apache.org/schemas/jaxrs.xsd"> <!-- 用于cxf实现ws和rs的标签配置 --> <import resource="classpath:META-INF/cxf/cxf.xml" /> <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" /> <import resource="classpath:META-INF/cxf/cxf-servlet.xml" /> <!-- 用于spring注解 --> <context:component-scan base-package="com.test"/> <!-- 发布ws,其中address是此ws的名称 --> <jaxws:endpoint id="user" implementor="com.test.UserServiceImpl" address="/user"/> <bean id="restful" class="com.test.restful.RestfulServiceImpl"/> <!-- 发布rs,其中address是此rs的名称 --> <jaxrs:server id="restfulService" address="/restful"> <jaxrs:serviceBeans> <ref bean="restful"/> </jaxrs:serviceBeans> <jaxrs:extensionMappings> <entry key="json" value="application/json" /> <entry key="xml" value="application/xml" /> </jaxrs:extensionMappings> </jaxrs:server> </beans>
