FastDFTJava client uses

1.1.java client

Mr. Yuqing provides a Java client, but as a C programmer, to write java code can be imagined. And it has been for a long time is not maintained.

It is recommended that an open source FastDFS client, support for the latest SpringBoot2.0.

Configuration is very simple to use, supports connection pooling, support for automatic generation of thumbnails, mad pull cool hanging fried God, there are wood.

Address: tobato / FastDFS_client

 

 

 

Next, we will use FastDFS transformation ~ ~ ~ -upload project.

 

1.1.1 The introduction of dependence

In the parent project, we have managed dependence, version:

<fastDFS.client.version>1.26.2</fastDFS.client.version>

 

So here we are directly introduced to coordinate the project in taotao-upload the pom.xml:

<dependency>
    <groupId>com.github.tobato</groupId>
    <artifactId>fastdfs-client</artifactId>
</dependency>

 

 

1.1.2. Introductory configuration class

 

 

 

Pure java configuration: 

@Configuration 
@Import (. FdfsClientConfig class )
 // solve jmx repeated registration of the bean 
@EnableMBeanExport (Registration = RegistrationPolicy.IGNORE_EXISTING)
 public  class FastClientImporter { 
    
}

 

 

1.1.3. Writing FastDFS property

Append the following in application.yml configuration file:

FDFS: 
  SO -timeout: 1501 # timeout 
  Connect -timeout: 601 # connection timeout 
  Thumb - Image: # thumbnail 
    width: 60 
    height: 60 
  Tracker -list: # Tracker Address: Your virtual machine server address + port (default is 22122)
     - 192.168.0.211:22122

 

1.1.4. Configuring hosts

The future through the domain name:. Image ~~~ .com domain name to access resources on the pictures fastDFS server. Therefore, it requires a proxy address to a virtual machine:

Configure the hosts file, so that image. ~~~ .com server can access fastDFS

 

 

 

1.1.5. Test

Create a test class:

 

 

 

The following copy into it:

 1 @SpringBootTest
 2 @RunWith(SpringRunner.class)
 3 public class FastDFSTest {
 4 ​
 5     @Autowired
 6     private FastFileStorageClient storageClient;
 7 ​
 8     @Autowired
 9     private ThumbImageConfig thumbImageConfig;
10 ​
11     @Test
12     public void testUpload() throws FileNotFoundException {
13         // 要上传的文件
14         File file = newFile ( "C: \\ joedy the Users \\ \\ \\ xbx1.jpg Pictures" );
 15          // uploading and storing the image, the parameter: Suffix 1- size uploaded file stream file 2- 3- 4- file Whether he can 
16          StorePath = storepath the this .storageClient.uploadFile (
 . 17                  new new the FileInputStream (File), file.length (), "JPG", null );
 18 is          // path with the packet 
. 19          System.out.println (storePath.getFullPath ());
 20          // path without packet 
21 is          System.out.println (storePath.getPath ());
 22 is      }
 23 is  24     @Test
 25 public void testUploadAndCreateThumb ()       throws a FileNotFoundException {
 26 is          File File = new new File ( "C: \\ joedy the Users \\ \\ \\ xbx1.jpg Pictures" );
 27          // upload and generate a thumbnail 
28          StorePath = storepath the this .storageClient.uploadImageAndCrtThumbImage (
 29                  new new the FileInputStream (File), file.length (), "PNG", null );
 30          // path with the packet 
31 is          System.out.println (storePath.getFullPath ());
 32          // path without packet 
33 is          the System. Out.println (storePath.getPath ());
 34 is          // Get the thumbnail path 
35         String path = thumbImageConfig.getThumbImagePath(storePath.getPath());
36         System.out.println(path);
37     }
38 }

 

result:

1 group1/M00/00/00/wKg4ZVsWl5eAdLNZAABAhya2V0c424.jpg
2 M00/00/00/wKg4ZVsWl5eAdLNZAABAhya2V0c424.jpg

5 M00/00/00/wKg4ZVsWmD-ARnWiAABAhya2V0c772_60x60.png

 

Access to the second set of the first path:

 

 

Access the last path (path thumbnail), pay attention to add the group name (group1) :
