Reg Spring批量交易

我的要求是我需要将两个数据源连接到Spring Batch Application .
1)一个用于Spring Batch Jobs and Executions存储
2)一个用于业务数据Stroing,Processing和Retreiving .
我知道有很多解决方案可以实现这一目标 . 但我通过将第二个数据源设置为主数据来实现 . 问题是第二个数据源不在事务范围内,而是提交每个sql语句,特别是通过jdbctemplate执行 .

env-context.xml 我有以下配置

<!-- Enable annotations-->
<context:annotation-config/>

<bean primary="true" id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName" value="java:/DB2XADS"/>
</bean>

<!-- Creating TransactionManager Bean, since JDBC we are creating of type 
    DataSourceTransactionManager -->

    class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

</bean>

<!-- jdbcTemplate uses dataSource -->
<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
    <property name="dataSource" ref="dataSource" />

<bean id="batchTransactionManager"

<bean id="transactionTemplate"
    class="org.springframework.transaction.support.TransactionTemplate">
    <property name="transactionManager" ref="transactionManager" />
</bean>

override-context.xml 我有以下代码

<tx:annotation-driven transaction-manager="transactionManager" />

<!-- jdbcTemplate uses dataSource -->
<bean id="batchDataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName" value="java:/MySqlDS"/>

    <property name="ignoreResourceNotFound" value="true"/>
    <property name="ignoreUnresolvablePlaceholders" value="true"/>
    <property name="order" value="1"/>
</bean>

<!-- Overrider job repository -->
<bean id="jobRepository"
      class="org.springframework.batch.core.repository.support.JobRepositoryFactoryBean">

    <property name="isolationLevelForCreate" value="ISOLATION_SERIALIZABLE"/>
    <property name="transactionManager" ref="batchTransactionManager"/>
</bean>

<!-- Override job service -->
<bean id="jobService" class="org.springframework.batch.admin.service.SimpleJobServiceFactoryBean">
    <property name="tablePrefix" value="${batch.table.prefix}"/>
    <property name="jobRepository" ref="jobRepository"/>

</bean>

job-config.xml 我有以下代码

<context:component-scan base-package="com.honda.*">
     <context:exclude-filter type="regex" 
               expression="com.honda.pddabulk.utility.MyBatch*" /> 
</context:component-scan>

我有自定义批量配置器集 . 现在问题是当我尝试使用jdbctemplate执行查询以进行更新并插入时,它不在事务中,这意味着@Transactional不起作用 .

而是为每个方法调用进行提交 . 这个例子是

@Transactional
public void checkInsertion() throws Exception{
    try{
        jdbcTemplate.update("INSERT INTO TABLE_NAME(COLUMN1, COLUMN2) VALUES( 'A','AF' );
        throw new PddaException("custom error");
    }catch(Exception ex){
        int count=jdbcTemplate.update("ROLLBACK");
        log.info("DATA HAS BEEN ROLLBACKED SUCCESSFULLY... "+count);        
        throw ex; 
    }

}

在上面的代码中,我试图插入数据,并立即我也抛出一个异常,这意味着插入应该发生,但提交不会 . 所以我们将无法看到任何数据,但遗憾的是提交正在进行 . 请一些帮助
