spring mvc基础篇(十三):综合案例二(注解版)
此本章主要是把上一章的增删改查案例改为相应的注解版本。
13.1 开发环境
开发工具:myeclipse8.6.1
数据库:mysql5.5.23
服务器: tomcat6.0.37
框架版本: spring3.2.2
13.2 结合jdbc，tomcat数据源对学生数据进行增删改查的管理
步骤一:在myeclipse8.6中新建web工程springmvczh02，拷贝如下包到lib目下：
步骤二:编写web.xml 配置文件，代码如下：
=================================web.xml========================
<?xmlversion="1.0" encoding="UTF-8"?>
<web-appversion="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<!-- 配置spring的字符集过滤 -->
<filter>
<filter-name>encode</filter-name>
<filter-class>org.springframework.web.filter
.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encode</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>*.php</url-pattern>
</servlet-mapping>
</web-app>
================================================================
步骤三：在tomcat里面配置数据源:
====================================================================
1.在tomcat的conf目录下找到context.xml,添加如下配置,请自行修改用户名和密码
<Resourcename="ds_mysql5.x"
auth="Container"
type="javax.sql.DataSource"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/studentdb"
username="root"
password="admin"
initialSize="1"
maxActive="20"
maxIdle="10"
maxWait="10000"/>
2.将mysql驱动包mysql-connector-java-5.1.26-bin.jar拷贝到tomcat的lib目录==================================================================
步骤四：在核心配置文件springmvc-servlet.xml里面编写如下配置
======================== springmvc-servlet.xml=======================
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<context:component-scan base-package="com.stu.controls,com.stu.dao "></context:component-scan>
<bean id="irvResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
</beans> ====================================================================
步骤五：其它代码不一一列出，只给出截图参考，需要的朋友请联系作者[email protected] ：

步骤六: 启动tomcat，发布项目，在地址栏输入 http://localhost:8080/springmvczh02/ 进行测试，参考运行界面如下:
