springmvc+mybatis+velocity配置

首先说明，在java的web框架中，最难的一个步骤，就是设置配置文件，配置文件复杂繁多，而且特别容易配置错误，经过不懈努力，一步步配置好了。

1、文件目录



本工程是eclipse+maven的webapp工程

2、webx.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 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_3_0.xsd"> <display-name></display-name>
<welcome-file-list>
<welcome-file>index/list</welcome-file>
</welcome-file-list>

<!-- Spring的log4j监听器 -->
<listener>
<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>

<!-- 核心控制器 -->
<servlet>
<servlet-name>book</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>

<!-- spring配置文件 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet-mapping>
<servlet-name>book</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>

</web-app>

3、spring-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd 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 http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd"> 
<!-- 自动扫描包 -->
<mvc:annotation-driven />
<context:component-scan base-package="click.youhua.*" />

<!-- velocity模板引擎 -->
<bean id="velocityConfigurer" class="org.springframework.web.servlet.view.velocity.VelocityConfigurer">
<property name="resourceLoaderPath" value="WEB-INF/view"/>
<property name="velocityProperties">
<props>
<prop key="input.encoding">utf-8</prop>
<prop key="output.encoding">utf-8</prop>
</props>
</property>
</bean>
<bean id="velocityViewResolver" class="org.springframework.web.servlet.view.velocity.VelocityViewResolver">
<property name="suffix" value=".vm"/>
<property name="contentType" value="text/html;charset=utf-8"/>
</bean>

<!-- 拦截器 -->
<mvc:interceptors>
<!-- 使用bean定义一个Interceptor，直接定义在mvc:interceptors根下面的Interceptor将拦截所有的请求 -->
<mvc:interceptor>
<mvc:mapping path="/index.do/**"/>
<!-- 定义在mvc:interceptor下面的表示是对特定的请求才进行拦截的 -->
<bean class="click.youhua.interceptor.LoginInterceptor"/>
</mvc:interceptor>
</mvc:interceptors>

</beans>

4、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" xmlns:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jdbc="http://www.springframework.org/schema/jdbc"
xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop"
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 http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd"> 
<!-- 配置数据源 -->
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://121.40.55.231:3306/youhua" />
<property name="username" value="root" />
<property name="password" value="123456" />
</bean>

<!-- 配置事务管理器 -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<!-- configLocation：用于指定Mybatis的配置文件位置 -->
</bean>

<context:annotation-config />

<tx:annotation-driven />

<!--
自动扫描和注册Mapper接口
basePackage是用来指定Mapper接口文件所在的基包，
在这个基包或其所有子包下面的Mapper接口都将被搜索到。
多个基包之间可以使用逗号或者分号进行分隔
-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="
click.youhua.mapper
" />
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
</bean>

</beans>

配置完成后，再加上对于各种model controller的设置，就可以正常访问到velocity的页面。

4、task/list.vm

#foreach($data in $list)
<tr>
<td>$data.id</td>
<td>$data.article_name</td>
<td>ipsum</td>
<td>dolor</td>
<td>sit</td>
</tr>
#end

5、结果



其中任务名称就是循环出来的结果。
