1.HSF服务的开发
1) 基于Maven创建一个web工程HSFService,如下图,其他的可以自定义。
2)创建好好在src/main目录下创建一个java目录,并将其设置为sources folder,如下图所示:
3) 配置项目的pom.xml,如下
1 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 2 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> 3 <modelVersion>4.0.0</modelVersion> 4 <groupId>com.hsf</groupId> 5 <artifactId>HSFService</artifactId> 6 <packaging>war</packaging> 7 <version>1.0-SNAPSHOT</version> 8 <name>HSFService Maven Webapp</name> 9 <url>http://maven.apache.org</url> 10 <properties> 11 <java-version>1.7.0_67</java-version> 12 </properties> 13 <dependencies> 14 <!-- Junit依赖包--> 15 <dependency> 16 <groupId>junit</groupId> 17 <artifactId>junit</artifactId> 18 <version>3.8.1</version> 19 <scope>test</scope> 20 </dependency> 21 <!--spring和servlet的依赖包--> 22 <dependency> 23 <groupId>javax.servlet</groupId> 24 <artifactId>servlet-api</artifactId> 25 <version>2.5</version> 26 </dependency> 27 <dependency> 28 <groupId>org.springframework</groupId> 29 <artifactId>spring</artifactId> 30 <version>2.5.6</version> 31 <type>jar</type> 32 <scope>compile</scope> 33 </dependency> 34 <!-- mysql依赖包--> 35 <dependency> 36 <groupId>mysql</groupId> 37 <artifactId>mysql-connector-java</artifactId> 38 <version>5.1.6</version> 39 </dependency> 40 <dependency> 41 <groupId>commons-dbcp</groupId> 42 <artifactId>commons-dbcp</artifactId> 43 <version>1.2.2</version> 44 </dependency> 45 <!-- Ibatits依赖包--> 46 <dependency> 47 <groupId>org.apache.servicemix.bundles</groupId> 48 <artifactId>org.apache.servicemix.bundles.ibatis-sqlmap</artifactId> 49 <version>2.3.4.726_4</version> 50 </dependency> 51 <!-- 淘宝HSF服务的依赖包--> 52 <dependency> 53 <groupId>com.taobao.hsf</groupId> 54 <artifactId>hsf.app.spring</artifactId> 55 <version>1.4.9.2</version> 56 </dependency> 57 </dependencies> 58 <build> 59 <finalName>HSFService</finalName> 60 <plugins> 61 <plugin> 62 <artifactId>maven-compiler-plugin</artifactId> 63 <configuration> 64 <source>${java-version}</source> 65 <target>${java-version}</target> 66 </configuration> 67 </plugin> 68 </plugins> 69 </build> 70 </project>
4) 编写服务接口和服务的实现
代码如下:
1 package com.hsf.services; 2 import java.lang.String; 3 public interface SayHelloService{ 4 public String sayHello(String user); 5 } 6 package com.hsf.services.impl; 7 import com.hsf.services.SayHelloService; 8 public class SayHelloServiceImpl implements SayHelloService { 9 public String sayHello(String user) { 10 return "Hello "+user+" ,Time is "+System.currentTimeMillis()+"(ms)"; 11 } 12 }
5) 在Spring的配置文件中配置HSFSpringProviderBean
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.springframework.org/schema/beans" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd "> 3 <!-- HSF服务配置--> 4 <!--配置SayHelloService服务的实现 --> 5 <bean id="SayHelloServiceImpl" class="com.hsf.services.impl.SayHelloServiceImpl"/> 6 <!--配置SayHelloService服务提供者--> 7 <bean id="SayHelloService" class="com.taobao.hsf.app.spring.util.HSFSpringProviderBean" init-method="init"> 8 <!--配置服务提供者对外提供的接口SayHelloService--> 9 <property name="serviceInterface"> 10 <value>com.hsf.services.SayHelloService</value> 11 </property> 12 <!--服务的实现者--> 13 <property name="target"> 14 <ref bean="SayHelloServiceImpl"/> 15 </property> 16 <property name="serviceVersion"> 17 <value>1.0.0.0.dev</value> 18 </property> 19 <!-- 组别一致的服务才能互相调用--> 20 <property name="serviceGroup"> 21 <value>HSF</value> 22 </property> 23 <property name="serviceName"> 24 <value>SayHello</value> 25 </property> 26 </bean> 27 <!--配置SayHelloService服务的消费者--> 28 <bean id="SayHelloServiceConsumer" class="com.taobao.hsf.app.spring.util.HSFSpringConsumerBean" init-method="init"> 29 <!--服务的接口名和版本号须与服务提供者定义的一致--> 30 <property name="interfaceName"> 31 <value>com.hsf.services.SayHelloService</value> 32 </property> 33 <property name="version"> 34 <value>1.0.0.0.dev</value> 35 </property> 36 </bean> 37 </beans>
6) 在Web.xml中配置spring的上下文环境
1 <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" > 2 <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_3_0.xsd" id="WebApp_ID" version="3.0"> 3 <display-name>HSFService</display-name> 4 <!-- 默认显示界面 --> 5 <welcome-file-list> 6 <welcome-file>index.jsp</welcome-file> 7 <welcome-file>index.html</welcome-file> 8 </welcome-file-list> 9 <!-- 配置spring上下文环境applicationContext --> 10 <context-param> 11 <param-name>contextConfigLocation</param-name> 12 <!-- 应用上下文配置文件 --> 13 <param-value>classpath*:applicationContext.xml</param-value> 14 </context-param> 15 <!--配置spring启动listener入口 --> 16 <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 17 </listener> 18 </web-app>
7) 将HSFService部署,启动tomcat,即可在HSF服务治理中心http://ops.jm.taobao.net/hsfops中根据自己主机的IP查找自己发布的服务
8) 将服务接口SayHelloService打成Jar包(二方包)以供客户端使用
2.HSF服务的使用
1) 在客户端的pom.xml文件中添加对HSF的依赖
1 <dependency> 2 <groupId>com.taobao.hsf</groupId> 3 <artifactId>hsf.app.spring</artifactId> 4 <version>1.4.9.2</version> 5 </dependency>
2) 在客户端的Spring配置文件中配置HSFSpringConsumerBean
1 <!--配置SayHelloService服务的消费者--> 2 <bean id="SayHelloServiceConsumer" class="com.taobao.hsf.app.spring.util.HSFSpringConsumerBean" init-method="init"> 3 <!--服务的接口名和版本号须与服务提供者定义的一致--> 4 <property name="interfaceName"> 5 <value>com.hsf.services.SayHelloService</value> 6 </property> 7 <property name="version"> 8 <value>1.0.0.0.dev</value> 9 </property> 10 </bean>
3)引入服务端打好的二方Jar包com.hsf.services.jar,创建SayHelloServlet使用服务
SayHelloServlet的代码如下:
1 package com.hsf.consumer; 2 import com.hsf.services.SayHelloService; 3 import org.springframework.web.context.WebApplicationContext; 4 import org.springframework.web.context.support.WebApplicationContextUtils; 5 import javax.servlet.ServletException; 6 import javax.servlet.http.HttpServlet; 7 import javax.servlet.http.HttpServletRequest; 8 import javax.servlet.http.HttpServletResponse; 9 import java.io.IOException; 10 import java.io.PrintWriter; 11 12 public class SayHelloServlet extends HttpServlet { 13 protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { 14 //通过ServletContext获取Spring的上下文 15 WebApplicationContext context= WebApplicationContextUtils.getWebApplicationContext(getServletContext()); 16 //通过BeanFactory获取服务的消费者SayHelloServiceConsumer 17 SayHelloService sayHelloService= (SayHelloService) context.getBean("SayHelloServiceConsumer"); 18 19 PrintWriter out=response.getWriter(); 20 //调用服务 21 out.println(sayHelloService.sayHello("xiwu.xxw")); 22 out.close(); 23 return; 24 } 25 protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { 26 doPost(request,response); 27 } 28 }
5)部署该web工程到tomcat,启动tomcat后访问http://localhost:8079/ SayHello?name=zhangsna 即可看到打印出“Hello zhangsan,Time is xxxxx (ms)”
