[Java知识库]Mybatis+Spring配置

一、导入依赖 (包含junit/spring-test测试）

<properties>
        <mybatis.version>3.4.5</mybatis.version>
        <mybatis-spring.version>1.3.1</mybatis-spring.version>
        <mysql-connector-java.version>5.1.47</mysql-connector-java.version>
        <druid.version>1.1.16</druid.version>
        <spring-context.version>5.1.6.RELEASE</spring-context.version>
        <spring-aspects.version>5.1.6.RELEASE</spring-aspects.version>
        <spring-test.version>5.1.6.RELEASE</spring-test.version>
        <spring-jdbc.version>5.1.6.RELEASE</spring-jdbc.version>
        <junit.version>4.12</junit.version>
    </properties>
    <dependencies>
        <!--    mybatis、-->
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis</artifactId>
            <version>${mybatis.version}</version>
        </dependency>
        <!--    mysql、-->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>${mysql-connector-java.version}</version>
            <scope>runtime</scope>
        </dependency>
        <!--    druid、-->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>${druid.version}</version>
        </dependency>
        <!--    mybatis-spring、-->
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis-spring</artifactId>
            <version>${mybatis-spring.version}</version>
        </dependency>
        <!--    spring-context、-->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>${spring-context.version}</version>
        </dependency>
        <!--    spring-aspects、-->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-aspects</artifactId>
            <version>${spring-aspects.version}</version>
        </dependency>
        <!--    junit、-->
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>${junit.version}</version>
        </dependency>
        <!--    spring-test-->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-test</artifactId>
            <version>${spring-test.version}</version>
        </dependency>
        <!--        spring-jdbc-->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-jdbc</artifactId>
            <version>${spring-jdbc.version}</version>
        </dependency>
    </dependencies>

二、配置applicationContext.xml、这里没有配置mybatis-config,如果要用到具体功能，还是要配置

    <context:component-scan base-package="com.wsj.mapper,com.wsj.service"/>
    <aop:aspectj-autoproxy/>
    <context:property-placeholder location="classpath:db.properties"/>
<!--配置dataSource druid连接池-->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="driverClassName" value="${jdbc.driver}"/>
        <property name="url" value="${jdbc.url}"/>
        <property name="username" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
    </bean>

<!--    配置SqlSessionFactoryBean-->
    <bean class="org.mybatis.spring.SqlSessionFactoryBean">
<!--        数据源-->
        <property name="dataSource" ref="dataSource"/>
<!--        注入扫描映射文件的路径 resources下的mapper-->
        <property name="mapperLocations" value="classpath:com/wsj/mapper/*.xml"/>
<!--        配置类别名文件 可以减少书写-->
        <property name="typeAliasesPackage" value="com.wsj.entity"/>
    </bean>
<!--配置mapper接口 java下的mapper-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.wsj.mapper"/>
    </bean>
