所以我有一个try / finally块.我需要在finally块中执行许多方法.但是,这些方法中的每一个都可以抛出异常.有没有办法确保在没有嵌套的finally块的情况下调用(或尝试)所有这些方法？
这就是我现在所做的,这非常难看：
protected void verifyTable() throws IOException {
Configuration configuration = HBaseConfiguration.create();
HTable hTable = null;
try {
hTable = new HTable(configuration,segmentMatchTableName);
//...
//varIoUs business logic here
//...
} finally {
try {
try {
if(hTable!=null) {
hTable.close(); //This can throw an IOException
}
} finally {
try {
generalTableHelper.deleteTable(configuration,segmentMatchTableName); //This can throw an IOException
} finally {
try {
generalTableHelper.deleteTable(configuration,wordMatchTableName); //This can throw an IOException
} finally {
generalTableHelper.deleteTable(configuration,haplotypeTableName); //This can throw an IOException
}
}
}
} finally {
HConnectionManager.deleteConnection(configuration,true); //This can throw an IOException
}
}
}
有更优雅的方式吗？
