spring实现jdbctemplate添加事务支持示例

复制代码 代码如下:

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

public abstract void commit();

public abstract void rollback();
}

复制代码 代码如下:

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;
 }

}
