spring Batch实现数据库大数据量读写

1. data-source-context.xml

?

<?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/beans/spring-beans-3.0.xsd
	http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
	http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">

	<!-- 1) USE ANNOTATIONS TO IDENTIFY AND WIRE SPRING BEANS. -->
	<context:component-scan base-package="net.etongbao.vasp.ac" />
	
	<!-- 2) DATASOURCE, TRANSACTION MANAGER AND JDBC TEMPLATE -->
 
	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
		destroy-method="close" abstract="false" scope="singleton">
		<!-- oracle.jdbc.driver.oracleDriver -->
		<property name="driverClass" value="oracle.jdbc.OracleDriver" />
		<property name="jdbcUrl" value="jdbc:oracle:thin:@192.168.1.23:1521:orcl01" />
		<property name="user" value="USR_DEV01" />
		<property name="password" value="2AF0829C" />
		<property name="checkoutTimeout" value="30000" />
		<property name="maxIdleTime" value="120" />
		<property name="maxPoolSize" value="100" />
		<property name="minPoolSize" value="2" />
		<property name="initialPoolSize" value="2" />
		<property name="maxStatements" value="0" />
		<property name="maxStatementsPerConnection" value="0" />
		<property name="idleConnectionTestPeriod" value="30" />	
	</bean>
	<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
		<property name="dataSource" ref="dataSource" />
	</bean>

	<bean id="transactionManager"
		class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="dataSource" />
	</bean>
	
	<tx:annotation-driven transaction-manager="transactionManager" />
</beans>

?2.?quartz-context.xml ? ? ??commit-interval="10000"每次批量数据的条数,数值越大效率越高,可在此处添加事物处理,

每次回滚数就是commit-interval数
