java - 如何在java类中处理和显示DataDecodeException日志

Question

我将 csv 文件读取到 java，所以我得到了 DataDecodeException 那么我该如何处理该异常， 到目前为止，我处理 smooks 异常并打印日志，如下所示“org.milyn.SmooksException:无法过滤源。”但我需要像这样打印日志 org.milyn.javabean.DataDecodeException: 无法解码 bean 'customer' 上属性 'telcoId' 的绑定(bind)值 'A'。我怎样才能实现这个目标？

异常(exception):

15:24:18,471 INFO  [STDOUT] [Mobee]- INFO 2012-11-01 15:24:18,471 [] MigrationCustomerHome - CSV File ..C:\Users\PEDDU\AppData\Local\Temp\-3dd9162f-13abbd6ef67--7f5a5802617468662164441.upload

简单代码:

try {
    //smooks Exception
} catch (SmooksException e) {

log.info("Smooks Exception   "+e);

}

Answer 1

目前尚不清楚您的目标是什么，但我猜测您希望在日志中看到完整的堆栈跟踪，而不仅仅是一行。如果是这种情况，您需要使用 log.error("Some message", e) 而不是 log.info("Some message "+ e)。

--- 根据OP的评论进行编辑---

这里是一个示例代码，可以满足您的需求。它遍历堆栈跟踪并挖掘出某种类型的第一个原因。它可以扩展到处理所需类型的原因多次发生并且您对第二次、第三次等发生感兴趣的情况:

try {
    throw new Exception(
        new Exception(
            new Exception(
                new RuntimeException("This is the one I am interested in", new RuntimeException()))));

} catch (Exception e) {
    dig(e);
}

private void dig(Throwable e) {
    if (e instanceof RuntimeException) {
        log.info("Some message " + e);

    } else if (e != null) {
        dig(e.getCause());
    }
}
