因为我无法编辑我的问题。我正在详细写另一篇文章
我的要求是我需要有两个数据源连接到 Spring Batch 应用程序。
1) 一个用于存储 Spring Batch Jobs 和 Executions
2) 一种用于业务数据检索、处理和检索。
在 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 -->
<bean id="transactionManager" primary="true"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
<!-- jdbcTemplate uses dataSource -->
<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
<property name="dataSource" ref="dataSource" />
</bean>
<bean id="batchTransactionManager"
class="org.springframework.batch.support.transaction.ResourcelessTransactionManager"/>
<bean id="transactionTemplate"
class="org.springframework.transaction.support.TransactionTemplate">
<property name="transactionManager" ref="transactionManager" />
</bean>
在 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"/>
</bean>
<bean class="com.honda.pddabulk.utility.MyBatchConfigurer">
<property name="dataSource" ref="batchDataSource" />
</bean>
<!-- Use this to set additional properties on beans at run time -->
<bean id="placeholderProperties"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:/org/springframework/batch/admin/bootstrap/batch.properties
</value>
<value>classpath:/batch/batch-mysql.properties</value>
<value>classpath:log4j.properties</value>
</list>
</property>
<property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE"/>
<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="databaseType" value="mysql"/>
<property name="dataSource" ref="batchDataSource"/>
<property name="tablePrefix" value="${batch.table.prefix}"/>
<property name="maxVarCharLength" value="2000"/>
<property name="isolationLevelForCreate" value="ISOLATION_SERIALIZABLE"/>
<property name="transactionManager" ref="batchTransactionManager"/>
</bean>
<!-- Override job service -->
<bean id="jobService" class="org.springframework.batch.admin.service.SimpleJobServiceFactoryBean">
<property name="tablePrefix" value="${batch.table.prefix}"/>
<property name="jobRepository" ref="jobRepository"/>
<property name="jobLauncher" ref="jobLauncher"/>
<property name="jobLocator" ref="jobRegistry"/>
<property name="dataSource" ref="batchDataSource"/>
</bean>
<!-- Override job launcher -->
<bean id="jobLauncher" class="org.springframework.batch.core.launch.support.SimpleJobLauncher">
<property name="jobRepository" ref="jobRepository" />
<property name="taskExecutor" ref="jobLauncherTaskExecutor" />
</bean>
<task:executor id="jobLauncherTaskExecutor" pool-size="21" rejection-policy="ABORT" />
<!-- Override job explorer -->
<bean id="jobExplorer"
class="org.springframework.batch.core.explore.support.JobExplorerFactoryBean">
<property name="tablePrefix" value="${batch.table.prefix}"/>
<property name="dataSource" ref="batchDataSource"/>
</bean>
在 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>
我设置了自定义批处理配置器。现在的问题是,当我尝试使用 jdbctemplate 执行查询以进行更新并插入它时,它不在事务下,这意味着 @Transactional 不起作用。
每个方法调用都会发生提交。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,并且立即我也抛出了一个异常,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,但不幸的是提交正在发生。请有人帮忙
