public abstract class UnsupportedStatementAdapter implements Statement
public class TStatement extends UnsupportedStatementAdapter
为什么要有adapter这个中间类?
public void commit() throws SQLException {
checkClosed();
if(isAutoCommit){
return;
}
SQLException sqlException = null;
boolean first = true;
for(Connection conn : openedConnection.values()){
try{
conn.commit();
}catch(SQLException e){
if(sqlException == null){
sqlException = e;
}
if(first){
// 第一次Commit就抛异常了,直接break
break;
}
}
first = false;
}
if(sqlException != null){
throw sqlException;
}
}
在connection.commit 中, 如果中间某个connection commit失败,但是其他的connection提交成功,这种情况怎么去保证数据的一致性呢?
