SSM整合环境搭建

一、书写配置文件

1.1 applicationcontext.xml

<?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:aop="http://www.springframework.org/schema/aop"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:tx="http://www.springframework.org/schema/tx"
       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.xsd
       http://www.springframework.org/schema/tx
       http://www.springframework.org/schema/tx/spring-tx.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context.xsd
" default-autowire="byName">
    <!--属性文件扫描-->
    <context:property-placeholder location="classpath:db.properties"></context:property-placeholder>
    <!--配置注解扫描-->
    <context:component-scan base-package="com.service.impl"></context:component-scan>
    <!--配置数据源bean-->
    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="${mysql.driver}"></property>
        <property name="url" value="${mysql.url}"></property>

    </bean>
    <!--配置工厂bean-->
    <bean id="factory" class="org.mybatis.spring.SqlSessionFactoryBean"></bean>
    <!--配置Mapper扫描bean-->
    <bean id="mapper" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="sqlSessionFactoryBeanName" value="factory"></property>
        <property name="basePackage" value="com.mapper"></property>
    </bean>
    <!--配置事务管理bean-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"></bean>
    <!--配置事务管理方法-->
    <tx:advice id="advice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="sel*" read-only="true"/>
            <tx:method name="ins*"></tx:method>
            <tx:method name="up*"></tx:method>
            <tx:method name="del*"></tx:method>
        </tx:attributes>
    </tx:advice>
    <!--配置事务管理切面-->
    <aop:config>
        <aop:pointcut id="mp" expression="execution(* com.service.impl.*.*(..))"/>
        <aop:advisor advice-ref="advice" pointcut-ref="mp"></aop:advisor>
    </aop:config>
</beans>

1.2 db.properties

mysql.driver=com.mysql.jdbc.Driver
mysql.url=jdbc:mysql://localhost:3306/spring?characterEncoding=UTF-8
mysql.username=root
mysql.password=112233

1.3 log4j.properties

### set log levels ###
log4j.rootCategory = info

### log4j.logger.com.mapper.Mapper = debug
### 以下代码表示log4j.logger.com.advice.* = debug
log4j.logger.com.advice = debug,stdout,D

### 打印到控制台
log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern = - %m%n

### 打印到文件
log4j.appender.D = org.apache.log4j.FileAppender
### 日志存放路径
log4j.appender.D.File = D:/log.log
log4j.appender.D.Append = true
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss}  [ %t:%r ] - [ %p ]  %m%n

1.4 springmvc.xml

<?xml version="1.0" encoding="UTF-8"?>

</beans>

1.5 web.xml
