The canonical reference for building a production grade API with Spring. Finally, we'll talk about how we can resume a download if our connection fails before the whole file is read. The performance increase comes from buffering. When reading one byte at a time using the read method, each method call implies a system call to the underlying file system.
This context switch is expensive from a performance perspective. The example above is very verbose, but luckily, as of Java 7, we have the Files class which contains helper methods for handling IO operations.
We can use the Files. Our code works well but can be improved. Its main drawback is the fact that the bytes are buffered into memory. The Java NIO package offers the possibility to transfer bytes between 2 Channels without buffering them into the application memory.
Depending on the underlying operating system, the data can be transferred directly from the filesystem cache to our file without copying any bytes into the application memory. On Linux and UNIX systems, these methods use the zero-copy technique that reduces the number of context switches between the kernel mode and user mode.
We've seen in the examples above how we can download content from a URL just by using the Java core functionality. We could wrap all the logic into a Callableor we could use an existing library for this. Notice that we've overridden the onBodyPartReceived method, download json file from url. This could lead to high memory consumption, or an OutOfMemory exception when trying to download a large file. ByteBuffers have the advantage that the memory is allocated outside of the JVM heap, so it doesn't affect out applications memory.
We can see from the Javadoc that there's a utility class named FileUtils that is used for general file manipulation tasks.
The underlying code uses the same concepts of reading in a loop some bytes from an InputStream and writing them download json file from url an OutputStream. One difference is the fact that here the URLConnection class is used to control the connection timeouts so that the download doesn't block for a large amount of time:.
Considering internet connections fail from time to time, it's useful for us to be able to resume a download, instead of downloading the file again from byte zero.
If so, we'll resume the download from the last byte recorded on disk:, download json file from url. What happens here is that we've configured the URLConnection to request the file bytes in a specific range. The range will start from the last downloaded byte and will end at the byte corresponding to the size of the remote file. Another common way to use the Range header is for downloading a file in chunks by setting different byte ranges.
For example, to download 2 KB file, we can use the range 0 — and — Another subtle difference from the code at section 2. After we've made this change the rest of the code is identical to the one we've seen in section 2. This implementation is safe to use even for large files because we don't load the whole file into memory. This is useful because it minimized the number of context switches done when reading and writing bytes and by using direct buffers, the bytes are not loaded into the application memory.
