Java异常处理

异常处理示例

以下代码用于展示异常处理：

try {
    // OSS操作，例如上传文件
    ossClient.putObject(...);
} catch (OSSException oe) {
    System.out.println("Caught an OSSException, which means your request made it to OSS, "
            + "but was rejected with an error response for some reason.");
    System.out.println("Error Message: " + oe.getErrorMessage());
    System.out.println("Error Code:       " + oe.getErrorCode());
    System.out.println("Request ID:      " + oe.getRequestId());
    System.out.println("Host ID:           " + oe.getHostId());
} catch (ClientException ce) {
    System.out.println("Caught an ClientException, which means the client encountered "
            + "a serious internal problem while trying to communicate with OSS, "
            + "such as not being able to access the network.");
    System.out.println("Error Message: " + ce.getMessage());
} finally {
    if (ossClient != null) {
        ossClient.shutdown();
    }
}
            

ClientException

ClientException指客户端尝试向OSS发送请求以及数据传输时遇到的异常。例如，当发送请求时网络连接不可用，则会抛出ClientException。当上传文件时发生IO异常，也会抛出ClientException。

OSSException

OSSException指服务器端异常，即对服务器错误信息的解析。OSSException包含OSS返回的错误码和错误信息，便于定位问题，并做出适当的处理。

OSSException通常包含以下错误信息：
