spring JpetStore学习笔记

首先看看工程的web.xml文件

指定web应用的根, 为WebAppRootListener,Log4jConfigListener使用
    <context-param>
        <param-name>webAppRootKey</param-name>
        <param-value>petstore.root</param-value>
    </context-param>

指定log4j配置文件位置
    <context-param>
        <param-name>log4jConfigLocation</param-name>
        <param-value>/WEB-INF/log4j.properties</param-value>
    </context-param>

配置文件,-local为后缀的是单数据库,-jta的为多数据库时
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            /WEB-INF/dataAccessContext-local.xml  /WEB-INF/applicationContext.xml
        </param-value>
        <!--
        <param-value>
            /WEB-INF/dataAccessContext-jta.xml  /WEB-INF/applicationContext.xml
        </param-value>
        -->
    </context-param>

启动时ContextLoaderServlet会装入上述配置文件
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

spring MVC servlet 使用这个,会生成一个工程名+-servlet.xml的文件作为映射配置文件.也就是说,在本例子里会生成web-inf目录下生成jpetstore-servlet.xml,用于分发配置.
    <servlet>
        <servlet-name>petstore</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>2</load-on-startup>
    </servlet>

struts的servlet,用于struts中request的请求映射,配置文件是struts-config.xml
    <servlet>
        <servlet-name>action</servlet-name>
        <servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
        <load-on-startup>3</load-on-startup>
    </servlet>

设置要处理的url,这里,注释了名为action的servlet,用了petstore.也就是说,没有使用struts而是使用的spring MVC
    <servlet-mapping>
        <servlet-name>petstore</servlet-name>
        <!--
        <servlet-name>action</servlet-name>
        -->
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>


官网上下载spring-framework-2.1-m3-with-dependencies.jar,解压取出\samples\jpetstore宠物商店项目,包括sql脚本,源码,工程文件,build.xml文件.这里我部属在tomcat6上,用的mysql数据库.

1>  配置tomcat的server.xml文件,HOST节点下添加上下文以及连接持,代码如下:
<Context path="/jpetstore" docBase="E:\study\jpetstore" 
                  debug="0" privileged="true" reloadable="true"   workDir="work\Catalina\localhost\jpetstore"> 
          <Logger className="org.apache.catalina.logger.FileLogger" prefix="localhost_admin_log." suffix=".txt" timestamp="true"/>
              <Resource name="jpetstore" auth="Container" type="javax.sql.DataSource"/>
                   <ResourceParams name="jpetstore">
                       <parameter>
                         <name>factory</name>
                         <value>org.apache.commons.dbcp.BasicDataSourceFactory</value>
                       </parameter>
                       <parameter>
                         <name>username</name>
                         <value>root</value>
                       </parameter>
                       <parameter>
                         <name>password</name>
                         <value></value>
                       </parameter>
                       <parameter>
                         <name>driverClassName</name>
                         <value>com.mysql.jdbc.Driver</value>
                       </parameter>
                       <parameter>
                         <name>url</name>
                         <value>jdbc:mysql://localhost:3306/jpetstore?autoReconnect=true</value>
                       </parameter>
                       <parameter>
                         <name>initialSize</name>
                         <value>20</value>
                       </parameter>
                       <parameter>
                         <name>maxActive</name>
                         <value>30</value>
                       </parameter>
                       <parameter>
                         <name>maxWait</name>
                         <value>10000</value>
                       </parameter>
                    </ResourceParams>
        </Context> 

2>   安装好mysql后,create database jpetstore; 然后导入db目录下的mysql脚本文件,jpetstore-mysql-schema.sql,jpetstore-mysql-dataload.sql

3>   修改工程下WEB-INF目录下的jdbc.properties文件,用#注释掉以前内容,用作mysql数据库,添加代码:
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/jpetstore?autoReconnect=true
jdbc.username=root
jdbc.password=
这里必须下在mysql的JDBC驱动放入lib包内.

至此,启动tomcat,输入http://localhost:8080/jpetstore,可以看到宠物商店的欢迎界面,部署成功.
