SSM的各个配置文件

SqlMapConfig.xml文件：（这是带了mybatis的分页插件的配置）

<?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>
<plugins>
<plugin interceptor="com.github.pagehelper.PageHelper">
<property name="dialect" value="mysql"/>
</plugin>
</plugins>

</configuration>

这里的数据库连接是采用阿里的druid的连接池，经过多方人士验证是目前最好的连接池。

db.properties：

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/数据库的名字?characterEncoding=utf-8
jdbc.username=连接的数据库的用户名
jdbc.password=连接的数据库的密码

关于spring的配置有下面几个：

applicationContext-dao.xml：（主要是用来进行数据库的连接）

springMVC.xml的配置：

http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<!--配置扫描包扫描controller -->
<context:component-scan base-package="com.taotao.controller" />
<!-- 利用这个来进行配置注解映射器和注解适配器 -->
<mvc:annotation-driven></mvc:annotation-driven>
<!-- <mvc:default-servlet-handler/>
-->
<!-- 配置jsp试图解析器,配置试图解析器的前缀和后缀，程序中不用指定前缀和后缀 -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
<!-- 定义文件上传解析器 -->
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<!-- 设定默认编码 -->
<property name="defaultEncoding" value="UTF-8"></property>
<!-- 设定文件上传的最大值5MB，5*1024*1024 -->
<property name="maxUploadSize" value="5242880"></property>
</bean>

<mvc:resources location="/WEB-INF/js/" mapping="/js/**"/>
<mvc:resources location="/WEB-INF/css/" mapping="/css/**"/>

 

</beans>

然后项目中的具体实现也是dao层（mapper）service的接口和实现controller的用来管理jsp页面传入的值和向页面返回，用来主要处理页面的跳转问题。
