1.创建一个maven工程，导入jar包，pom.xml的配置如下：
<dependencies>

</dependency>
<!-- servlet api-->

</dependency>
<!-- jsp api-->
<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>jsp-api</artifactId>

<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.7.25</version>
</dependency>
<!-- jdbc自带日志的jar包-->
<dependency>
<groupId>commons-logging</groupId>
<artifactId>commons-logging</artifactId>
<version>1.2</version>
</dependency>
<!--jstl标签相关依赖的jar包 -->
<dependency>
<groupId>org.apache.taglibs</groupId>
<artifactId>taglibs-standard-spec</artifactId>
<version>1.2.5</version>
</dependency>
<!--jstl标签相关依赖的jar包 -->
<dependency>
<groupId>org.apache.taglibs</groupId>
<artifactId>taglibs-standard-impl</artifactId>
<version>1.2.5</version>
</dependency>
<!--数据库的jar包-->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.46</version>
</dependency>
<!--数据库连接池的jar包-->
<dependency>
<groupId>com.mchange</groupId>
<artifactId>c3p0</artifactId>
<version>0.9.5.2</version>
</dependency>
<!--mybatis的jar包-->
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis</artifactId>
<version>3.4.6</version>
</dependency>
<!--mybatis-spring整合的jar包-->
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis-spring</artifactId>
<version>1.3.2</version>
</dependency>
<!--mybatis缓存框架jar包-->
<dependency>
<groupId>org.mybatis.caches</groupId>

</dependency>
<!--分页查询的jar包-->
<dependency>
<groupId>com.github.pagehelper</groupId>
<artifactId>pagehelper</artifactId>
<version>5.1.4</version>
</dependency>
<!--逆向工程-->
<dependency>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-core</artifactId>
<version>1.3.7</version>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<extensions>true</extensions>
</plugin>
<!--逆向工程-->
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<configuration>
<configurationFile>${basedir}/src/main/resources/generatorConfig.xml</configurationFile>
<verbose>true</verbose>
<overwrite>true</overwrite>
</configuration>
</plugin>
</plugins> </build> 2.在web.xml里做spring和springmvc的初始配置 <welcome-file-list> <welcome-file>login.jsp</welcome-file> </welcome-file-list> <!--spring的初始化：给spring框架指定配置文件的位置--> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring.xml</param-value> </context-param> <!--Listener：spring和JavaWeb之间的一个整合--> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!--springMVC的初始化配置：指明springMVC配置文件的位置，初始化servlet--> <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:springMVC.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcherServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>
3.SpringMVC只扫描Controller和ControllerAdvice:
<!-- 配置包扫描 -->
<context:component-scan base-package="cn.ybzy.ssmweb" use-default-filters="false">
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
<context:include-filter type="annotation" expression="org.springframework.web.bind.annotation.ControllerAdvice"/>
</context:component-scan>
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
<mvc:annotation-driven></mvc:annotation-driven>
<mvc:default-servlet-handler/>
4.Spring排除扫描Controller和ControllerAdvice:
<!-- 配置包扫描 -->
<context:component-scan base-package="com.hy.springmvc">
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
<context:exclude-filter type="annotation" expression="org.springframework.web.bind.annotation.ControllerAdvice"/>
</context:component-scan>
5.jdbc.properties:
jdbc.user=root
jdbc.password=root
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.jdbcUrl=jdbc:mysql://localhost:3306/mybatisdemo？?characterEncoding=UTF-8
jdbc.acquireIncrement=10
jdbc.initialPoolSize=30
jdbc.minPoolSize=5
jdbc.maxPoolSize=40
jdbc.maxStatements=1000
jdbc.maxStatementsPerConnection=100
6.Spring的配置:
<context:property-placeholder location="classpath:jdbc.properties"/>
<!-- 配置C3P0数据连接池 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="user" value="${jdbc.user}"></property>
<property name="password" value="${jdbc.password}"></property>
<property name="driverClass" value="${jdbc.driverClass}"></property>
<property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property>
<property name="acquireIncrement" value="${jdbc.acquireIncrement}"></property>
<property name="initialPoolSize" value="${jdbc.initialPoolSize}"></property>
<property name="minPoolSize" value="${jdbc.minPoolSize}"></property>
<property name="maxPoolSize" value="${jdbc.maxPoolSize}"></property>
<property name="maxStatements" value="${jdbc.maxStatements}"></property>
<property name="maxStatementsPerConnection" value="${jdbc.maxStatementsPerConnection}"></property>
</bean>
<!-- 事务配置 -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>
<!-- 配置事务属性 -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="get*" read-only="true"/>
<tx:method name="load*" read-only="true"/>
<tx:method name="find*" read-only="true"/>
<tx:method name="select*" read-only="true"/>
<tx:method name="*" read-only="false"/>
</tx:attributes>
</tx:advice>
<!-- 配置事务的切入点 -->
<aop:config>
<aop:pointcut expression="execution(* cn.ybzy.springdemo.service.*.*(..))"
id="txPointcut"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="txPointcut"/>
</aop:config>
<!-- 整合Mybatis -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="configLocation" value="classpath:mybatis-config.xml"></property>
<property name="mapperLocations" value="classpath:cn/ybzy/ssmweb/dao/*.xml"></property>
</bean>
<!--这个配置用不了-->
<!--<mybatis-spring:scan base-package="cn.ybzy.ssmweb.dao"/>-->
<bean id="mapperScannerConfig" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="only.mxb.keshe.dao" />
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
</bean>
7.log4j.properties:
log4j.rootLogger = debug,stdout, D
log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target = System.out
log4j.appender.stdout.Threshold = INFO
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p %m%n
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = ./log4j.log
log4j.appender.D.Append = true
log4j.appender.D.Threshold = DEBUG
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern=%d %p %m%n
9.逆向工程:generatorConfig.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration

<!-- 默认false，把JDBC DECIMAL 和 NUMERIC 类型解析为 Integer，为 true时把JDBC DECIMAL和NUMERIC类型解析为java.math.BigDecimal -->
<javaTypeResolver>

</javaTypeResolver>
<!--targetPackage目标包，生成实体类的位置-->

<!--指定数据库表，要和数据库中进行对应，否则将会出错-->
<table tableName="address"></table>
<!-- enableCountByExample="false" enableUpdateByExample="false"-->
<!-- enableDeleteByExample="false" enableSelectByExample="false"-->
<!-- selectByExampleQueryId="false"-->
<table tableName="admin"></table>
