properties中的参数用于版本锁定, 根据需要修改即可, 另外, 其他的工具类根据需要添加即可

设置SpringMvc配置文件

<?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:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <!-- 配置视图解析器 -->
    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

    <!-- 配置文件解析器 -->
    <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <property name="maxUploadSize" value="10485760"/>
    </bean>

    <!-- 静态资源放行 -->
    <mvc:default-servlet-handler/>
    <!-- 开启注解 -->
    <mvc:annotation-driven/>

</beans>

异常解析器和拦截器根据需求自己配

Spring配置文件applicationContext.xml配置(我在Spring的配置文件中设置了MybBatis的所有信息, 所以不再配置MyBatis的配置文件)

            </bean>
        </property>
    </bean>
    <!-- 配置mapper文件的路径, 配置了该bean就不用写Mapper的实现了 -->

配置文件中需要修改的地方, 我都用 TODO 标注了, 按需修改即可

在Tomcat的web.xml中配置spring和springMvc

配置spring随服务器启动而启动并加载配置文件

<!-- 配置服务器启动加载spring配置文件 -->
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
</context-param>

配置springMvc

<!-- 配置spring-mvc -->
<servlet>
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring-mvc.xml</param-value>
    </init-param>
</servlet>
<servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>
<!-- 字符编码过滤器 -->
<filter>
    <filter-name>characterEncodingFilter</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>
</filter>
<filter-mapping>
    <filter-name>characterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

本文代码: 此处的 ssm-demo
SSM整合依赖包括:

spring依赖(基础包, aop, 切面, 事务, jdbc)
springMvc依赖(webMvc)
mybatis依赖(mybatis包, mybatis-spring整合包)
数据库驱动包(mysql)
servlet, jsp, jstl支持
工具包(酌情删减)
1. 文件上传(fileupload)
2. 连接池(c3p0)
3. json转化(jackson)\
4. 跨服务器文件传输依赖(jersey-client: 已注释)
5. github分页(pagehelper)
测试和日志打印
