Manven+Eclipse搭建面向服务式架构

面向服务式架构应用场景大多是在企业级应用中会用到。面向服务的体系结构，是一个组件模型，它将应用程序的不同功能单元（称为服务）通过这些服务之间定义良好的接口和契约联系起来。接口是采用中立的方式进行定义的，它应该独立于实现服务的硬件平台、操作系统和编程语言。这使得构建在各种这样的系统中的服务可以以一种统一和通用的方式进行交互。

在某些大型企业中， 会存在多个不同功能的系统，但有些底层的功能是每个系统都会有的，在这种情况下，为了避免功能的重复，也避免系统的不关联，所以就有了面向服务架构的出现。面向服务可以将一个大型企业的每个系统都有的功能做成一个服务，该服务只提供接口，其他系统要实现该功能只需调用该服务的接口则能实现某个功能。例如：每个系统都会有权限和用户，可以把权限和用户模块做成一个服务，提供接口，其他系统调用该接口就可以进行登录等操作。

1、  新建提供方(service)MavenWeb项目

要引用必须的jar包和各种配置文件要配置正确。

先pom.xml配置：

<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

接着applicationContext.xml配置：

<?xml version="1.0" encoding="UTF-8"?><beansxmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:p="http://www.springframework.org/schema/p"xmlns:context="http://www.springframework.org/schema/context"xmlns:aop="http://www.springframework.org/schema/aop"xmlns:tx="http://www.springframework.org/schema/tx"  xsi:schemaLocation="http://www.springframework.org/schema/tx    http://www.springframework.org/schema/tx/spring-tx-3.1.xsdhttp://www.springframework.org/schema/aop       http://www.springframework.org/schema/aop/spring-aop-3.1.xsdhttp://www.springframework.org/schema/context      http://www.springframework.org/schema/context/spring-context-3.1.xsd  http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd"><!-- 开启注解 --><context:annotation-config /><!-- 自动扫描(service)，(dao) --><context:component-scan base-package="end.gx.dao,end.gx.service"><context:include-filter type="annotation" expression="org.springframework.stereotype.Service" /><context:include-filter type="annotation" expression="org.springframework.stereotype.Repository" /></context:component-scan></beans>

再接着spring-mybatis.xml和jdbc.properties配置：

jdbc.properties：

driverClassName=com.mysql.jdbc.Driverurl=jdbc:mysql://192.168.3.16:3306/hotelmanagementsystem?useUnicode=true&characterEncoding=utf-8username=rootpassword=123validationQuery=SELECT 1

还有就是spring-xfire.xml配置：

<?xml version="1.0" encoding="UTF-8"?>  <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">  <beans><!--引入XFire预配置信息 --><import resource="classpath:org/codehaus/xfire/spring/xfire.xml" /><!--使用注解 --><bean id="webAnnotations" class="org.codehaus.xfire.annotations.jsr181.Jsr181WebAnnotations" /><bean id="jsr181HandlerMapping" class="org.codehaus.xfire.spring.remoting.Jsr181HandlerMapping"><property name="xfire" ref="xfire" /><property name="webAnnotations" ref="webAnnotations" /></bean><!--定义访问的url --><bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"></bean><!--使用XFire导出器 --><bean id="baseWebService" class="org.codehaus.xfire.spring.remoting.XFireExporter"lazy-init="false" abstract="true"><!--引用xfire.xml中定义的工厂 --><property name="serviceFactory" ref="xfire.serviceFactory" /><!--引用 xfire.xml 中的 实例 --><property name="xfire" ref="xfire" /></bean></beans>

最后是web.xml配置：

<?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>Archetype Created Web Application</display-name>    <context-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml,classpath:spring-mybatis.xml,classpath:spring-xfire.xml</param-value></context-param><listener><description>spring监听器</description><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><servlet><servlet-name>xfireServlet</servlet-name><servlet-class>org.codehaus.xfire.spring.XFireSpringServlet</servlet-class></servlet><servlet-mapping><servlet-name>xfireServlet</servlet-name><!-- 访问接口时的配置 --><url-pattern>/services/*</url-pattern></servlet-mapping></web-app>

接口UserService的写法：

UserServiceImpl的写法：

提供者(service)搭建完成，在eclipse运行该项目，运行起来后，在浏览器访问该项目发布出来的接口。如果能访问到，就证明该项目基本没问题。

点击后出现下面的界面，基本能确定该服务发布成功。

出现上面的界面后，可以对该项目进行打包成war文件。接着放到其他服务器的tomcat上运行。其他项目想要用该项目中的某些功能，直接调用它的接口就行。调用方法会在消费方(web)中提到。

2、  新建消费方(web) MavenWeb项目

该项目要引用jar包，所用到的包基本和提供方所用到的包一样。还有就是各种配置文件，该项目不会用到数据库的配置文件。

先pom.xml配置：

<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

接着applicationContext.xml配置：

<?xml version="1.0" encoding="UTF-8"?><beansxmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:p="http://www.springframework.org/schema/p"xmlns:context="http://www.springframework.org/schema/context"xmlns:aop="http://www.springframework.org/schema/aop"xmlns:tx="http://www.springframework.org/schema/tx"  xsi:schemaLocation="http://www.springframework.org/schema/tx    http://www.springframework.org/schema/tx/spring-tx-3.1.xsdhttp://www.springframework.org/schema/aop       http://www.springframework.org/schema/aop/spring-aop-3.1.xsdhttp://www.springframework.org/schema/context      http://www.springframework.org/schema/context/spring-context-3.1.xsd  http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd"><!-- 开启注解 --><context:annotation-config /><!-- 自动扫描(service) --><context:component-scan base-package="end.gx.service"><context:include-filter type="annotation" expression="org.springframework.stereotype.Service" /><context:include-filter type="annotation" expression="org.springframework.stereotype.Repository" /></context:component-scan></beans>

再有spring-mvc.xml配置：

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd"><!-- 自动扫描controller包下的所有类，使其认为spring mvc的控制器 --><context:component-scan base-package="edu.gx.web"><context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/></context:component-scan><!-- 日期转换  必须放在<mvc:annotation-driven />前面 --><bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"></bean><mvc:annotation-driven /><!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 -->      <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/><!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 -->      <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" >          <property name="prefix" value="/WEB-INF/jsp"></property>          <property name="suffix" value=".jsp"></property>      </bean>  </beans>

最后web.xml配置：

<?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">          <display-name>Archetype Created Web Application</display-name>    <context-param>    <param-name>contextConfigLocation</param-name>    <param-value>classpath:applicationContext.xml</param-value>  </context-param>  <listener>    <description>spring监听器</description>    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  </listener>    <servlet>    <servlet-name>springMvc</servlet-name>    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>    <init-param>      <param-name>contextConfigLocation</param-name>      <param-value>classpath:spring-mvc.xml</param-value>    </init-param>    <init-param>            <param-name>activeReverseAjaxEnabled</param-name>            <param-value>true</param-value>    </init-param>    <load-on-startup>1</load-on-startup>  </servlet>    <servlet-mapping>    <servlet-name>springMvc</servlet-name>    <url-pattern>*.do</url-pattern>  </servlet-mapping>    <!-- 解决中文乱码问题 -->  <filter>    <filter-name>characterEncodingFilter</filter-name>    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>    <init-param>      <param-name>encoding</param-name>      <param-value>utf8</param-value>    </init-param>    <init-param>      <param-name>forceEncoding</param-name>      <param-value>true</param-value>    </init-param>  </filter>  <filter-mapping>    <filter-name>characterEncodingFilter</filter-name>    <url-pattern>/*</url-pattern>  </filter-mapping></web-app>

接着是接口UserService的写法：

还有就是UserServiceImpl写法：

消费者搭建完成，在eclipse运行该项目，运行过程不报错，该项目基本没问题。在提供者(service)运行的情况下，消费者在浏览器进行访问，如果能正常返回数据，则面向服务架构搭建完成。
