SSM整合配置文件

Spring

applicationContext.xml

db.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/test2?useSSL=true&useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=123456

Mybatis

mybatis-config.xml

<?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>
        <!--驼峰标识-->
        <setting value="true" name="mapUnderscoreToCamelCase"/>
        <!--开启二级缓存-->
        <setting value="true" name="cacheEnabled"/>
    </settings>
</configuration>

因为mybatis的配置都集合在了soring中了，所以里面的内容很少。

也可以在spring中配置驼峰标识和二级缓存，那样的话mybatis.xml就可以删除了

<bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="mapperLocations" value="classpath:mapper/*.xml"></property>
        <property name="configuration">
            <bean class="org.apache.ibatis.session.Configuration">
                <property name="mapUnderscoreToCamelCase" value="true"/>
            </bean>
        </property>
</bean>

 

SpringMVC
