Spring整合Mybatis

1. 新建Maven项目，添加依赖

新建时，选择maven-archetype-quickstart

1.1. 添加Spring依赖包

<!-- spring 依赖 -->
<!-- spring 核心依赖 -->
<dependency>
	<groupId>org.springframework</groupId>
	<artifactId>spring-context</artifactId>
	<version>${spring.version}</version>
</dependency>

<dependency>
	<groupId>org.springframework</groupId>
	<artifactId>spring-beans</artifactId>
	<version>${spring.version}</version>
</dependency>

<dependency>
	<groupId>org.springframework</groupId>
	<artifactId>spring-core</artifactId>
	<version>${spring.version}</version>
</dependency>

<!-- spring dao 依赖 -->
<dependency>
	<groupId>org.springframework</groupId>
	<artifactId>spring-jdbc</artifactId>
	<version>${spring.version}</version>
</dependency>

<dependency>
	<groupId>org.springframework</groupId>
	<artifactId>spring-tx</artifactId>
	<version>${spring.version}</version>
</dependency>

1.2. 添加Mybatis依赖包

<!-- DAO框架：mybatis依赖 -->
<dependency>
	<groupId>org.mybatis</groupId>
	<artifactId>mybatis</artifactId>
	<version>3.3.0</version>
</dependency>

<dependency>
	<groupId>org.mybatis</groupId>
	<artifactId>mybatis-spring</artifactId>
	<version>1.2.3</version>
</dependency>

1.3. 添加其他依赖包

<!-- 日志相关 -->
<dependency>
	<groupId>org.logback-extensions</groupId>
	<artifactId>logback-ext-spring</artifactId>
	<version>0.1.4</version>
</dependency>
<dependency>
	<groupId>org.slf4j</groupId>
	<artifactId>jcl-over-slf4j</artifactId>
	<version>1.7.12</version>
</dependency>
<dependency>
	<groupId>org.slf4j</groupId>
	<artifactId>slf4j-api</artifactId>
	<version>1.7.12</version>
</dependency>

<dependency>
	<groupId>ch.qos.logback</groupId>
	<artifactId>logback-core</artifactId>
	<version>1.1.1</version>
</dependency>
<dependency>
	<groupId>ch.qos.logback</groupId>
	<artifactId>logback-classic</artifactId>
	<version>1.1.1</version>
</dependency>

<!-- 数据库连接池 -->
<dependency>
	<groupId>com.alibaba</groupId>
	<artifactId>druid</artifactId>
	<version>1.0.15</version>
</dependency>

2. 配置Spring

<?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"
	xmlns:jpa="http://www.springframework.org/schema/data/jpa"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd

		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd"
>

	<context:property-placeholder ignore-resource-not-found="false" location="classpath:jdbc.properties" />

	<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
		<property name="driverClassName" value="${jdbc.driverClassName}" />
		<property name="url" value="${jdbc.url}" />
		<property name="username" value="${jdbc.username}" />
		<property name="password" value="${jdbc.password}" />
		<property name="initialSize" value="${jdbc.initialSize}" />
		<property name="maxActive" value="${jdbc.maxActive}" />
		<property name="filters" value="${jdbc.filters}" />

		<property name="removeAbandoned" value="${jdbc.removeAbandoned}" />
		<property name="removeAbandonedTimeout" value="${jdbc.removeAbandonedTimeout}" />
		<property name="logAbandoned" value="${jdbc.logAbandoned}" />
	</bean>

	<!-- 配置 sqlSessionFactory 自定义实现了typeAliasesPackage支持通配符的功能 -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<!-- 注入数据库连接池 -->
		<property name="dataSource" ref="dataSource" />
		<!-- 配置mybatis全局配置文件 -->
		<property name="configLocation" value="classpath:mybatis-config.xml" />
		<!-- 扫描entity包,使用别名 -->
		<property name="typeAliasesPackage" value="com.hwj.*.model" />
		<!-- 扫描sql配置文件：映射需要的xml文件 -->
		<property name="mapperLocations" value="classpath:sqlmap/**/*.xml" />
	</bean>

	<!-- 扫描所有Mybatis相关的接口 -->
	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
		<property name="basePackage" value="com.hwj.*.dao" />
	</bean>

	<!-- 配置事务管理器 -->
	<bean id="transactionManager" class=" org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<!-- 注入数据库连接池 -->
		<property name="dataSource" ref="dataSource" />
	</bean>
</beans>

3. 配置Mybatis

<?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>
		<setting name="cacheEnabled" value="true" />
		<setting name="lazyLoadingEnabled" value="true" />
		<setting name="multipleResultSetsEnabled" value="true" />
		<setting name="useColumnLabel" value="true" />
		<setting name="defaultExecutorType" value="REUSE" />
		<setting name="defaultStatementTimeout" value="25000" />
		<setting name="mapUnderscoreToCamelCase" value="true" />
		<setting name="jdbcTypeForNull" value="NULL" />
		<setting name="logImpl" value="SLF4J" />
	</settings>

</configuration>

4. 测试

@Test
public void test() {
	ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
	DonorInfoMapper mapper = ctx.getBean(DonorInfoMapper.class);
	System.out.println(mapper);
	DonorInfo info = mapper.selectByPrimaryKey("4AE8395D0931489AB4179935E459896B");
	System.out.println("------------------------------------------:" + ToStringBuilder.reflectionToString(info));

}
