Spring：使用JdbcTemplate的简单实例-基于注释

1. 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">

    <welcome-file-list>

       <welcome-file>index.jsp</welcome-file>

    </welcome-file-list>

    <servlet>

       <servlet-name>Dispatcher</servlet-name>

       <servlet-class>

           org.springframework.web.servlet.DispatcherServlet

       </servlet-class>

       <init-param>

           <param-name>contextConfigLocation</param-name>

           <param-value>/WEB-INF/applicationContext.xml</param-value>

       </init-param>

    </servlet>

    <servlet-mapping>

       <servlet-name>Dispatcher</servlet-name>

       <url-pattern>*.html</url-pattern>

    </servlet-mapping>

    <filter>

       <filter-name>SetCharacterEncoding</filter-name>

       <filter-class>

           com.lz.filter.SetCharacterEncodingFilter

       </filter-class>

       <init-param>

           <param-name>encoding</param-name>

           <param-value>utf-8</param-value>

       </init-param>

    </filter>

    <filter-mapping>

       <filter-name>SetCharacterEncoding</filter-name>

       <url-pattern>/*</url-pattern>

    </filter-mapping>
