多个异常捕获块Java 8 Eclipse

问题描述

我收到IOException的未处理消息异常.正如您在粘贴的代码中看到的那样，我已经处理了IOException. Eclipse和Eclipse的JDK该项目是Java 8更新121，因此支持知道捕获多个异常.我在做什么错了?

I'm getting an unhandled message exception for IOException. As you can see in the pasted code I've handled the IOException. The JDK for both eclipse & the project is Java 8 update 121 so I know catching multiple exceptions is supported. What am I doing wrong?

    try (InputStream inputStream = BatchMessageProperties.class.getClassLoader().
            getResourceAsStream(propertiesFileName)) {

        load(inputStream);
        //need to make sure all properties are present & not null.
        validate(this);

    } catch (IOException | InvalidBatchMessagePropertiesFileException ex) {

        logger.error(ex.getLocalizedMessage());
        ex.printStackTrace();
        throw ex;
    }

推荐答案

您确实将ex扔到了catch块中，它可能是IOException，对吧?

You do rethrow ex inside your catch block, which may be an IOException, right?
