SpringMVC+MyBatis+Freemarker 简单框架搭建(一)
一、开发环境:
Eclipse、Tomcat、SVN等请参见如下的帖子,很详细了。
http://www.iteye.com/topic/982182
svn和maven插件的安装:
1、先安装gef插件
地址:http://download.eclipse.org/tools/gef/updates/interim/
2、安装svn插件
地址:http://subclipse.tigris.org/update_1.6.x
3、maven插件
m2eclipse-core Update 地址: http://m2eclipse.sonatype.org/sites/m2e
m2eclipse-extras Update 地市: http://m2eclipse.sonatype.org/sites/m2e-extras
4、安装可能出现的问题
直接在线安装maven2 会出现依赖插件找不到的问题,无法安装。必须先安装gef 插件后才能安 装m2eclipse-core 插件,然而安装m2eclipse-extras 插件又依赖subclipse 插件。所以,三个插 件的正确的安装顺序是:gef插件 》subclipse插件 》m2eclipse插件
二、web.xml 和 applicationContext.xml 配置
1、web.xml文件配置:
<?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"
version="2.5">
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!-- Spring MVC 配置 -->
<servlet>
<servlet-name>springServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:contextConfigLocation-springService.xml</param-value>
</init-param>
<load-on-startup>0</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!-- 事件监听器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- shiro 权限控制的过滤器 -->
<!-- Spring 刷新Introspector防止内存泄露 -->
<listener>
<listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
</listener>
<!-- session超时定义,单位为分钟 -->
<session-config>
<session-timeout>20</session-timeout>
</session-config>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<!-- 设置servlet编码开始 -->
<filter>
<filter-name>Set Character Encoding</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>GB2312</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>Set Character Encoding</filter-name>
<url-pattern>/</url-pattern>
</filter-mapping>
<!-- 设置servlet编码结束 -->
<display-name>Archetype Created Web Application</display-name>
</web-app>
<context-param>节点和<listener>节点是web项目启动时最先读取的两个节点,所以这两个节点里面所配置的内容是web项目启动时最先加载的部分。
<context-param>节点中配置的applicationContext.xml里面主要是数据库的配置信息,以及事务等等
<listener>节点配置的是web请求的监听器
2、applicationContext.xml 内容如下:
<?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:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context"
xmlns:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd
">
<!-- 自动注解除Controller以外的Component -->
<context:component-scan base-package="com.weiluo.example">
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
<!-- 此配置可以让我们以${xxx}的形式来读取property.properties里面的信息 -->
<!-- <context:property-placeholder/> -->
<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:jdbc.properties</value>
</list>
</property>
</bean>
<!-- 配置数据源 -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="${jdbc.driver}"></property>
<property name="url"
value="${jdbc.url}"></property>
<property name="username" value="${jdbc.username}"></property>
<property name="password" value="${jdbc.password}"></property>
<!-- Connection Pooling Info -->
<property name="maxActive" value="${dbcp.maxActive}" />
<property name="maxIdle" value="${dbcp.maxIdle}" />
<property name="defaultAutoCommit" value="false" />
<!-- 连接Idle一个小时后超时 -->
<property name="timeBetweenEvictionRunsMillis" value="360000" />
<property name="minEvictableIdleTimeMillis" value="360000" />
</bean>
<!-- 配置SessionFactory -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"
p:dataSource-ref = "dataSource"
p:configLocation = "classpath:sqlMapConfig.xml" />
<!-- 采用spring与mybatis整合的第二种方法 -->
<bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate">
<constructor-arg index="0" ref="sqlSessionFactory" />
</bean>
<!-- 配置事务管理器 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"
p:dataSource-ref = "dataSource" />
<!-- MapperScanner配置,自动搜索mapper里面的对象,并注入 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"
p:basePackage = "com.weiluo.example.entity" />
<!-- 启动Spring注解事务 -->
<tx:annotation-driven/>
</beans>
3、web.xml中的<servlet>节点配置的是与请求处理相关的一些内容,主要是 url路由处理器,视图解析器,等等,如下:
<beans xmlns="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:util="http://www.springframework.org/schema/util" xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="

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">
<!-- url映射拦截器 -->
<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
<property name="order" value="1" />
</bean>
<!-- 配置数据格式转换器 -->
<bean
class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="messageConverters">
<list>
<ref bean="jsonHttpMessageConverter" />
</list>
</property>
</bean>
<bean id="jsonHttpMessageConverter"
class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
</bean>
<!-- 开启controller注解支持 -->
<!-- 注:如果base-package=cn.javass 则注解事务不起作用 TODO 读源码 -->
<context:component-scan base-package="com.weiluo.example.controller">
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
<!-- 因为web-inf目录下面的静态资源文件是不能直接通过目录过去的,所以需要特殊声明-->
<mvc:resources location="/static/" mapping="/static/**" />
<!-- 视图解析器 -->
<bean id="viewResolver"
class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
<property name="cache" value="true" />
<property name="prefix" value="" />
<property name="suffix" value=".html" />
<property name="exposeSpringMacroHelpers" value="true" />
<property name="exposeRequestAttributes" value="true" />
<property name="exposeSessionAttributes" value="true" />
<property name="requestContextAttribute" value="rc" />
<property name="contentType" value="text/html;charset=GB2312" />
<property name="order" value="0"/>
</bean>

追问
你说的这个和我想要的答案不太一样啊,我想要的不一样啊,我不用maven和svn,我就自己开发的。而且我不用Mybatis,用jdbc。
