配置之前现需要引入依赖的jar包：
*Spring
*SpringMvc
*Mybatis
*数据库连接池，驱动包
*其他(jstl,Servlet ,Junit..)
1.poxm.xml

2.本项目还使用了BootStrap前端框架，故到官网下载Bootstrap。在webapp目录下创建static文件保存我们的静态文件。同时将我们下载的Bootstrap解压到该目录下。
3.编写SSM整合的关键配置文件
web.xml
<?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" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> <display-name>Archetype Created Web Application</display-name> <!-- 启动Spring的容器 --> <!-- needed for ContextLoaderListener --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!-- Bootstraps the root web application context before servlet initialization --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- SpringMVC的前端控制器 --> <!-- The front controller of this Spring Web application, responsible for handling all application requests --> <servlet> <servlet-name>dispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <!-- Map all requests to the DispatcherServlet for handling --> <servlet-mapping> <servlet-name>dispatcherServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!-- 字符编码过滤器 --> <filter> <filter-name>CharacterEncodingFilte</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> <init-param> <param-name>forceRequestEncoding</param-name> <param-value>true</param-value> </init-param> <init-param> <param-name>forceResponseEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>CharacterEncodingFilte</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 使用Rest风格的URI 将页面post请求转化为指定的delete或者put --> <filter> <filter-name>HiddenHttpMethodFilter</filter-name> <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class> </filter> <filter-mapping> <filter-name>HiddenHttpMethodFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 加载log4j配置文件 --> <context-param> <param-name>log4jConfigLocation</param-name> <param-value>classpath:log4j.properties</param-value> <!-- <param-value>/WEB-INF/log4j.xml</param-value> --> </context-param> <listener> <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> </listener> </web-app>
4.在WEB-INF目录下创建dispatcherServlet-servlet.xml（spring mvc的配置文件）文件，，同时在java目录下创建我们需要的包，配置如下：
<?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:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> <!-- Spring mvc 的配置文件，包含网站跳转逻辑的控制、配置 --> <context:component-scan base-package="com.atguigu" use-default-filters="false"> <!-- 只扫瞄控制器 --> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <!-- 视图解析器，方便页面返回 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/views/"></property> <property name="suffix" value=".jsp"></property> </bean> <!-- 两个标准配置 --> <!-- 将Spring mvc不能处理的请求将给Tomcat --> <mvc:default-servlet-handler/> <!-- 能支持Spring MVC更高级的内容 如JSR303校验，快捷的ajax 。。。映射动态请求 --> <mvc:annotation-driven/> </beans>
5.创建applicationContext.xml(spring的配置文件)，同时创建数据库的配置文件dbconfig.properties。
applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!-- sping 的配置文件，这里主要配置和业务逻辑相关的 --> <!-- ====================================================数据源，事物控制，xxx --> <context:component-scan base-package="com.atguigu"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <context:property-placeholder location="classpath:dbconfig.properties"/> <bean id="pooledDataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property> <property name="driverClass" value="${jdbc.driverClass}"></property> <property name="user" value="${jdbc.user}"></property> <property name="password" value="${jdbc.password}"></property> </bean> <!--=============================================================== 配置和mybatis的整合 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- 制定Mybatis全局配置文件的位置 --> <property name="configLocation" value="classpath:mybatis-config.xml"></property> <property name="dataSource" ref="pooledDataSource"></property> <property name="mapperLocations" value="classpath:mapper/*.xml"></property> </bean> <!-- 配置扫描器，将mybatis接口的实现加入到ioc容器中 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <!-- 扫瞄所有dao接口的实现，加入到ioc容器中 --> <property name="basePackage" value="com.atguigu.crud.dao"></property> </bean> <!-- 配置一个可以批量操作的sqlSession --> <bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate"> <constructor-arg name="sqlSessionFactory" ref="sqlSessionFactory"></constructor-arg> <constructor-arg name="executorType" value="BATCH"></constructor-arg> </bean> <!-- ===================================================================== --> <!-- =======================================================================事物控制的配置 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <!-- 控制住数据源 --> <property name="dataSource" ref="pooledDataSource"></property> </bean> <!-- 开启注解的事物，使用xml配置形式的事物（必要主要的使用配置式） --> <aop:config> <!-- 切入点表达式 --> <aop:pointcut expression="execution(* com.atguigu.crud.service..*(..))" id="txPoint"/> <!-- 配置事物增强 --> <aop:advisor advice-ref="txAdvice" pointcut-ref="txPoint"/> </aop:config> <!-- 配置事物增强，事物如何切入 --> <tx:advice id="txAdvice"> <tx:attributes> <!-- 所有的方法都是事物方法 --> <tx:method name="*"/> <!-- 以get开始的所有方法都是查询 --> <tx:method name="get*" read-only="true"/> </tx:attributes> </tx:advice> <!-- Spring配置文件的核心点（数据源、与mybatis的整合、事物控制） --> </beans>
dbconfig.properties
jdbc.jdbcUrl=jdbc:mysql://localhost:3306/ssm_crud jdbc.driverClass=com.mysql.jdbc.Driver jdbc.user=root jdbc.password=admin
6.mybatis-config.xml文件，同时在resources目录下创建mapper文件夹。
<?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> <settings> <!-- <setting name="mapUnderscoreToCamelCase" value="true"/> --> <setting name="logImpl" value="LOG4J"/> </settings> <typeAliases> <package name="com.atguigu.crud.bean"/> </typeAliases> <plugins> <plugin interceptor="com.github.pagehelper.PageInterceptor"> <property name="reasonable" value="true"/> </plugin> </plugins> </configuration>
至此基本的配置已经完成。
