淘宝HSF服务的原理以及简单的实现

淘宝HSF服务具体来说分三个应用：api接口，service服务，本地应用。

最基本的Api服务应该是十分干净的，不含方法，只有接口。它是要被打包(jar包的形式)到中央仓库去的。

service服务是api接口的实现，它是要被打包成（最常见的是war包）安装到远程tomcat，或jboss中，作为服务要随时等待各种应用的调用的。

本地应用自然是各种应用了。

接口部分的pom文件：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org /POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion>
<groupId>com.taobao.hsftest</groupId>
<artifactId>itest</artifactId>
<version>1.0.0.SNAPSHOT</version>
</project>

接口：

package com.taobao.itest;

public interface HelloService {

public void sayHello();
}

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"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd"> <bean id="helloWorldServiceImpl" class="com.taobao.itest.impl.HelloService"></bean>
<bean class="com.taobao.hsf.app.spring.util.HSFSpringProviderBean" init-method="init">
<property name="serviceInterface">

<property name="serviceVersion">

启动文件:

package com.taobao.itest.impl;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.taobao.hsf.hsfunit.HSFEasyStarter;

public class Main {

public static void main(String[] args) {
try {
HSFEasyStarter.startFromPath("D:\\taobao-hsf");
Thread.sleep(1000);

new ClassPathXmlApplicationContext("applicationContext.xml");
System.out.println("Start end by zhanqiong!");
} catch (Exception e) {
System.out.println(e.getMessage());
}
}
}

也可以将server交给容器启动，此时首先需要该工程为war工程

在web.xml文件中添加spring管理

<?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_2_5.xsd" id="WebApp_ID" version="2.5">
<display-name>service</display-name>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationcontext.xml</param-value>
</context-param>
<listener>

</listener>
</web-app>

打包部署到tomcat或jboss容器下

三个工程的具体实现我已经跑通并且放到了我本地的资源文件了。
