[API Server]jersey 檔案多檔上傳
1. POM
2.上傳網頁
<dependency>
<groupId>org.glassfish.jersey.containers</groupId>
<artifactId>jersey-container-servlet</artifactId>
<version>2.17</version>
</dependency>
<dependency>
<groupId>org.glassfish.jersey.containers</groupId>
<artifactId>jersey-container-servlet-core</artifactId>
<version>2.17</version>
</dependency>
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-multipart</artifactId>
<version>2.17</version>
</dependency>
2.上傳網頁
<html>
<head>
<title<TODO supply a title</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
<body>
<form action="API/file/MultiUpload" method="post" enctype="multipart/form-data" >
<p>
Select a file : <input type="file" name="file" />
</p>
<p<
Select a file : <input type="file" name="file" />
</p>
<input type="submit" value="Upload It" />
</form>
</body>
</html>
3.API Server 設定
import javax.ws.rs.ApplicationPath;
import org.glassfish.jersey.server.ResourceConfig;
import org.glassfish.jersey.media.multipart.MultiPartFeature;
@ApplicationPath("API")
public class APIService extends ResourceConfig {
public APIService() {
packages("test.API");
//須註冊這個才可以上傳檔案
register(MultiPartFeature.class);
}
}
4.上傳API撰寫
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.io.UnsupportedEncodingException;
import javax.ws.rs.Consumes;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import org.glassfish.jersey.media.multipart.FormDataContentDisposition;
import org.glassfish.jersey.media.multipart.FormDataParam;
@Path("/file")
public class UploadFileService {
@POST
@Path("/MultiUpload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces(MediaType.TEXT_HTML + "; charset=UTF-8")
public Response uploadmutliFile(
FormDataMultiPart formData
) throws UnsupportedEncodingException {
// 取出多值的資料 file
Listparts = formData.getFields("file"); //檔案說明
FormDataContentDisposition disp = null;
//檔案串流
InputStream inputstream = null;
//檔案名稱
String fileName = "";
//檔案目錄
String folder = "D://";
//檔案路徑
String uploadedFileLocation = "";
for (FormDataBodyPart part : parts) {
//取得檔案說明
disp = part.getFormDataContentDisposition();
//取得檔案串流
inputstream = part.getValueAs(InputStream.class);
//檔名及編碼設定
fileName = new String(disp.getFileName().getBytes("ISO8859-1"), "UTF-8");
//設定檔案路徑
uploadedFileLocation = folder + fileName;
//寫入
writeToFile(inputstream, uploadedFileLocation);
}
return Response.status(200).entity("Success").build();
}
// 寫入資料夾內
private void writeToFile(
InputStream uploadedInputStream,
String uploadedFileLocation) {
OutputStream out;
try {
int read = 0;
byte[] bytes = new byte[1024];
out = new FileOutputStream(new File(uploadedFileLocation));
while ((read = uploadedInputStream.read(bytes)) != -1) {
out.write(bytes, 0, read);
}
out.flush();
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}

有處理兩個問題
[FATAL] No injection source found for a parameter of type public javax.ws.rs.core.Response的問題
－＞register(MultiPartFeature.class);
中文檔案亂碼
－＞String fileName = new String(fileDetail.getFileName().getBytes("ISO8859-1"), "UTF-8");
若有疑問可在提出：）
