java - OutOfMemoryError - 通过 weblogic 服务器

Question

如何解决 weblogic 服务器中的 OutOfMemoryError

增加堆大小 - -Xmx10G、-Xms10G实现了 SFTP 而不是 FTP

byte[] fileArr = null; ByteArrayOutputStream 输出；

    StringBuilder strBuild = new StringBuilder();

    strBuild.append(path);

    strBuild.append(fileName);
InputStream inputStr = null;

    BufferedInputStream bis = null;

    ByteBuffer buffer = null;

    ReadableByteChannel inputChannel = null;
            WritableByteChannel outputChannel = null;


    try {

        inputStr = this.sftpClient.getInputStream(strBuild.toString());

                if(READ_BUFFER_SIZE <= 0){          

                    buffer = ByteBuffer.allocateDirect(DEFAULT_BUFFER_SIZE);
                }

                else{
                    buffer = ByteBuffer.allocateDirect(READ_BUFFER_SIZE);

                }

                bis = new BufferedInputStream(inputStr);

                out = new ByteArrayOutputStream();

                inputChannel = Channels.newChannel(bis);

                outputChannel = Channels.newChannel(out);

                while (inputChannel.read(buffer) > 0) {
                    buffer.flip();

                    outputChannel.write(buffer);

                    buffer.compact();
                }

需要输入文件的 ByteArray 中的响应

在您的代码中，我没有看到您在哪里关闭了流。可能服务器会保留您打开的缓冲区。

插入 try-with-resource ( https://docs.oracle.com/javase/tutorial/essential/exceptions/tryResourceClose.html ) 或关闭代码中的流
