Examples with ByteArrayInputStream org.fusesource.hawtbuf.ByteArrayInputStream used on opensource projects

Example 1 with ByteArrayInputStream

use of org.fusesource.hawtbuf.ByteArrayInputStream in project spring-boot by spring-projects.

the class HeapdumpMvcEndpointTests method invokeShouldReturnGzipContent.

@Test
public void invokeShouldReturnGzipContent() throws Exception {
    MvcResult result = this.mvc.perform(get("/heapdump")).andExpect(status().isOk()).andReturn();
    byte[] bytes = result.getResponse().getContentAsByteArray();
    GZIPInputStream stream = new GZIPInputStream(new ByteArrayInputStream(bytes));
    byte[] uncompressed = FileCopyUtils.copyToByteArray(stream);
    assertThat(uncompressed).isEqualTo("HEAPDUMP".getBytes());
}

Example 2 with ByteArrayInputStream

use of org.fusesource.hawtbuf.ByteArrayInputStream in project vcell by virtualcell.

the class VCMessageJms method loadBlobFile.

/**
 * see Property jmsBlobMessageMinSize "vcell.jms.blobMessageMinSize"
 * see Property jmsBlobMessageTempDir "vcell.jms.blobMessageTempDir"
 * see class MessageProducerSessionJms
 *
 * 1) Message Producer serializes into byte[] and compares size with PropertyLoader.jmsBlobMessageMinSize.
 * 2) For Large Object Messages (> threshold bytes), MessageProducerSessionJms writes bytes to a local file (e.g. MyBlobMessageTempDir/BlobMessage2295645974283237270.data).
 * 3) Pass file name as message properties so that receiver can delete file when done.
 * 4) consumer-side VCMessage infrastructure receives BlobMessage and invokes VCMessageJms.loadBlobMessage()
 * 5) loadBlobMessage() reads object from stream and attempts to delete both original and broker files.
 * 6) consumer's message listener calls getObjectContent() not knowing if it was sent as a Blob or not.
 * 7) message consumer calls VCMessageJms.removeBlobFile() to clean up disk.
