新老客户大回馈,云服务器低至5折

2019-01-03

第一步

准备环境：idea，maven，jdk，tomcat，mysql，oracle

以上软件的安装配置不再赘述。

第二步

创建项目，添加maven管理jar包

 

引入jar包到pom文件

 

由于oralce连接数据库的驱动jar包maven没有，需要手动引入

pom文件的jar：

第三步

 

搭建项目框架

 

（导入web支持，spring支持和mybatis支持会自动导入）

 第四步

配置相关配置文件

配置文件：

applicationContent.xml 主配置文件

<?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: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/tx

   http://www.springframework.org/schema/tx/spring-tx.xsd">

<!--开启注解扫描功能-->
<context:annotation-config></context:annotation-config>
<!--定义注解扫描的包-->
<context:component-scan base-package="com.qy.mapper"></context:component-scan>
<context:component-scan base-package="com.qy.service"></context:component-scan>
<context:component-scan base-package="com.qy.domain"></context:component-scan>
<!--开启aop自动代理模式-->
<aop:aspectj-autoproxy proxy-target-class="true"/>

<!--从上下文环境中读取db.properties配置文件-->

<!--通过mybatis和spring结合的类，创建sqlsessionFactory-->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <!--指定myabtis配置文件位置-->

<!-- Mapper接口所在包名，Spring会自动查找其下的Mapper -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="com.qy.mapper" />
</bean>
<!-- (事务管理)transaction manager, use JtaTransactionManager for global tx -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource" />
</bean>

<!-- 配置事务属性 -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
    <tx:attributes>
        <tx:method name="save*"    propagation="REQUIRED"/>
        <tx:method name="update*"  propagation="REQUIRED"/>
        <tx:method name="delete*"  propagation="REQUIRED"/>
        <tx:method name="*" propagation="NOT_SUPPORTED"></tx:method>
    </tx:attributes>
</tx:advice>

<!-- 配置事务切入点 -->
<aop:config>
    <aop:pointcut expression="execution(* com.qy.service.impl.*.*(..))" id="pointCut"/>
    <aop:advisor advice-ref="txAdvice" pointcut-ref="pointCut"/>
</aop:config>
</beans>

db.properties 数据库配置文件

mysql.driverClassName=com.mysql.jdbc.Driver
mysql.url=jdbc:mysql://localhost:3306/java1807
mysql.username=root
mysql.password=123456
mysql.maxActive=100
mysql.initialSize=5

oracle.driverClassName=oracle.jdbc.OracleDriver
oracle.url=jdbc:oracle:thin:@localhost:1521:orcl
oracle.username=scott
oracle.password=tiger
oracle.maxActive=100
oracle.initialSize=5

log4j2.xml 日志配置文件

（需要在mybatis-config中配置setting）

 

<!--使用log4j2 配置输出-->
<setting name="logImpl" value="LOG4J2"/>
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="trace">

    </Appenders>
    <Loggers>
        <Root level="trace">

            <AppenderRef ref="Console"/>
        </Logger>

    </Loggers>
</Configuration>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
</web-app>

第五步

java目录下的mapper层代替了原来的Dao层（写接口）

原来dao层实现类变成了resources目录下相应级目录的***Mapper.xml

Mapper.xml里面写mybatis特有的crue（sql）语句。

 

 

大功告成！
