spring+mybatis整合（二）

一、applicationContext.xml配置

<!-- 设置扫描类 -->
<context:component-scan base-package="com.xxx.xxx"></context:component-scan>

<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
   <property name="driverClassName" value="com.mysql.jdbc.Driver" />
   <property name="connectionProperties"><value>useUnicode=true;characterEncoding=utf-8;autoReconnect=true</value></property>
   <!-- 基本属性 url、user、password -->
   <property name="url" value=" jdbc:mysql://xxx.xxx.xxx.xxx:3306/xxx?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true" />
   <property name="username" value="xxxxxx" />
   <property name="password" value="xxxxxx" />

   <!-- 配置初始化大小、最小、最大 -->
   <property name="initialSize" value="1" />
   <property name="minIdle" value="1" />
   <property name="maxActive" value="20" />

   <!-- 配置获取连接等待超时的时间 -->
   <property name="maxWait" value="60000" />

   <!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 -->
   <property name="timeBetweenEvictionRunsMillis" value="60000" />

   <!-- 配置一个连接在池中最小生存的时间，单位是毫秒 -->
   <property name="minEvictableIdleTimeMillis" value="300000" />

   <property name="validationQuery" value="SELECT 'x'" />
   <property name="testWhileIdle" value="true" />
   <property name="testOnBorrow" value="false" />
   <property name="testOnReturn" value="false" />

   <!-- 打开PSCache，并且指定每个连接上PSCache的大小 -->
   <property name="poolPreparedStatements" value="true" />
   <property name="maxPoolPreparedStatementPerConnectionSize" value="20" />

   <!-- 配置监控统计拦截的filters -->
   <property name="filters" value="stat" />
</bean>

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
       <property name="dataSource" ref="dataSource" />
       <!-- 自动扫描entity目录, 省掉Configuration.xml里的手工配置 -->
       <property name="typeAliasesPackage" value="com.xxx.xxx.spoc.vo" />
       <!-- 显式指定Mapper文件位置 -->
       <property name="mapperLocations" value="classpath:/mybatis/*Mapper.xml" />
       <!-- mybatis全局配置 -->
       <property name="configLocation" value="classpath:/META-INF/spring/mybatis-config.xml" />
       <!-- MyBatis分页插件配置 -->
       <property name="plugins">
           <array>
               <bean class="com.github.pagehelper.PageHelper">
                   <property name="properties">
                       <value>
                           dialect=mysql
                           reasonable=true
                           pageSizeZero=true
                       </value>
                   </property>
               </bean>
           </array>
       </property>
   </bean>

<!-- 扫描basePackage下所有以@MyBatisRepository标识的 接口-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="com.xxx.dao" />
    <property name="annotationClass" value="com.xxx.dao.MyBatisRepository"/>
</bean>

<!-- 事务控制 -->
<bean name="transactionManager"
    class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource"></property>
</bean>

<!-- 配置事务传播特性 -->
<tx:advice id="transactionAdvice" transaction-manager="transactionManager">
    <tx:attributes>
        <tx:method name="insert*" propagation="REQUIRED" />
        <tx:method name="add*" propagation="REQUIRED" />
        <tx:method name="create*" propagation="REQUIRED" />
        <tx:method name="delete*" propagation="REQUIRED" />
        <tx:method name="remove*" propagation="REQUIRED" />
        <tx:method name="update*" propagation="REQUIRED" />
        <tx:method name="edit*" propagation="REQUIRED" />
        <tx:method name="modify*" propagation="REQUIRED" />
        <tx:method name="save*" propagation="REQUIRED" />
        <tx:method name="get*" propagation="SUPPORTS" read-only="true" />
        <tx:method name="query*" propagation="SUPPORTS" read-only="true" />
        <tx:method name="find*" propagation="SUPPORTS" read-only="true" />
        <tx:method name="select*" propagation="SUPPORTS" read-only="true" />
        <tx:method name="*" propagation="SUPPORTS" read-only="true" />
    </tx:attributes>
</tx:advice>
<!-- 配置参与事务的方法 -->
<aop:config proxy-target-class="true">
    <aop:pointcut id="allServiceMethod"
        expression="execution(* com.xxx.service.*.impl.*Impl.*(..))" />
    <aop:advisor pointcut-ref="allServiceMethod" advice-ref="transactionAdvice"/>
</aop:config>

二、META-INF/spring/mybatis-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
    PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
    "mybatis-3-config.dtd">
<configuration>
   <!-- 配置全局属性 -->
   <settings>
      <!-- 获取自增主键 -->
      <setting name="useGeneratedKeys" value="true" />
      <!-- 使用列别名替换列名 -->
      <setting name="useColumnLabel" value="true" />
      <!-- 开启驼峰命名转换 -->
      <setting name="mapUnderscoreToCamelCase" value="true" />
   </settings>
</configuration>

三、注解MyBatisRepository

 1 import java.lang.annotation.Documented;
 2 import java.lang.annotation.ElementType;
 3 import java.lang.annotation.Retention;
 4 import java.lang.annotation.RetentionPolicy;
 5 import java.lang.annotation.Target;
 6 
 7 import org.springframework.stereotype.Component;
 8 
 9 /**
10  * 标识MyBatis的DAO,方便{@link org.mybatis.spring.mapper.MapperScannerConfigurer}的扫描。
11  * 
12  */
13 @Retention(RetentionPolicy.RUNTIME)
14 @Target(ElementType.TYPE)
15 @Documented
16 @Component
17 public @interface MyBatisRepository {
18    String value() default "";
19 }

四、Dao类配置

@MyBatisRepository
public interface IFamousTeacherDao {
      //  接口……

}
