SSM整合配置文件

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

    		<artifactId>javax.servlet-api</artifactId>
    		<version>3.1.0</version>
    		<scope>provided</scope>

          <!-- jsp api-->

    	</dependency>
          <!-- slf4j和log4j12转换，关联的jar包-->
    	<dependency>
    		<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>
          <!--数据库的jar包-->
    	<dependency>

    		<artifactId>mysql-connector-java</artifactId>
    		<version>5.1.46</version>
    	</dependency>
           <!--数据库连接池的jar包-->

    		<version>0.9.5.2</version>
    	</dependency>
           <!--mybatis的jar包-->
    	<dependency>
    		<groupId>org.mybatis</groupId>
    		<artifactId>mybatis</artifactId>

    	</dependency>
      <!--mybatis-spring整合的jar包-->

        </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
