想了解spring实现jdbctemplate添加事务支持示例的相关内容吗，在本文为您仔细讲解jdbctemplate事务的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：jdbctemplate,事务，下面大家一起来学习吧。

public interface JdbcTemplate extends JdbcOperations {
public abstract void beginTranstaion();

public abstract void commit();

public abstract void rollback();
}

public class JdbcTemplateImpl extends org.springframework.jdbc.core.JdbcTemplate implements JdbcTemplate {

private PlatformTransactionManager platformTransactionManager;
private DefaultTransactionDefinition transactionDefinition;
private ThreadLocal<TransactionStatus> transcationStatus = new ThreadLocal<TransactionStatus>();

public void beginTranstaion() {
TransactionStatus tmp = platformTransactionManager.getTransaction(transactionDefinition);
transcationStatus.set(tmp);
}

public void commit() {
  TransactionStatus tmp = transcationStatus.get();
  if (tmp == null) {
   throw new RMSRuntimeException("no transcation");
  }
  platformTransactionManager.commit(tmp);
  transcationStatus.remove();
}

public void rollback() {
  TransactionStatus tmp = transcationStatus.get();
  if (tmp == null) {
   throw new RMSRuntimeException("no transcation");
  }
  platformTransactionManager.rollback(tmp);
  transcationStatus.remove();

}

@Override
public void afterPropertiesSet() {
  super.afterPropertiesSet();
  transactionDefinition = new DefaultTransactionDefinition();
  transactionDefinition.setIsolationLevel(TransactionDefinition.ISOLATION_READ_COMMITTED);
  transactionDefinition.setPropagationBehavior(TransactionDefinition.PROPAGATION_REQUIRED);
  platformTransactionManager = new DataSourceTransactionManager(getDataSource());

}

public PlatformTransactionManager getPlatformTransactionManager() {
return platformTransactionManager;
}

public DefaultTransactionDefinition getTransactionDefinition() {
return transactionDefinition;
}

public ThreadLocal<TransactionStatus> getTranscationStatus() {
return transcationStatus;
}

}
