- 架包搭配.(架包不匹配经常报出一些莫名其秒的问题)
新建一个项目 并导入以下架包(这里少一个mysql的驱动包)

3.配置WEB.xml
<?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">
<servlet>
<servlet-name>test</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!--
DispatcherServlet 默认加载的bean文件是/WEB-INF/(servlet-name)-servlet.xml
可以通过配置contextConfigLocation来改变加载的文件
-->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/*Context.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<!--为DispatcherServlet建立映射 -->
<servlet-mapping>
<servlet-name>test</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
4在web-Inf下面新建aplicationContext.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:tx="http://www.springframework.org/schema/tx"
xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
<!-- 开启注解模式 -->
<mvc:annotation-driven />
<!-- 对org.simple下所有包下的类的注解进行扫描,并自动创建bean实例和装配bean -->
<context:component-scan base-package="org.simple"></context:component-scan>
<!-- 配置视图 -->
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/" />
<property name="suffix" value=".jsp" />
<!--
可为空,方便实现自已的依据扩展名来选择视图解释类的逻辑
-->
<property name="viewClass">
<value>org.springframework.web.servlet.view.InternalResourceView
</value>
</property>
</bean>
</beans>
继续新建一个daoContext.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:tx="http://www.springframework.org/schema/tx"
xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
<!-- 载入MySql配置 文件-->
<context:property-placeholder location="classpath:MySql.properties" />
<!-- 配置DataSource数据源-->
<bean id="DataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${jdbc.driverClassName}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.user}" />
<property name="password" value="${jdbc.password}" />
</bean>
<!-- Spring-Mybatis整合 -->
<bean id="SqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="configLocation" value="classpath:MyBatis-config.xml" />
<property name="dataSource" ref="DataSource" />
</bean>
<!-- 自动扫描mappar-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="org.simple.dao"></property>
</bean>
</beans>
5.在src下面建立一个Mybatis-Config.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<typeAliases>
<typeAlias alias="User" type="org.simple.model.User"/>
</typeAliases>
<mappers>
<mapper resource="org/simple/dao/mapper/UserMapper.xml"/>
</mappers>
</configuration>
不写了 感觉自己在copy代码 没啥解释 因为小弟也刚刚接触 不久。 直接上源码好了。
