尝试将文件上传到JAX-RS（球衣）服务器

如果要将Strings添加到

FormDataMultiPart

.field("name","value")

下面是一个工作示例：

首先，服务器部分以字符串形式返回读取文件的内容：

@Path("file")public class FileResource {    @POST    @Consumes(MediaType.MULTIPART_FORM_DATA)    public Response handleUpload(@FormDataParam("file") InputStream stream) throws Exception {        return Response.ok(IOUtils.toString(stream)).build();    }}

其次，客户端方法发布文件：

public void upload(String url, String fileName) {    InputStream stream = getClass().getClassLoader().getResourceAsStream(fileName);    FormDataMultiPart part = new FormDataMultiPart().field("file", stream, MediaType.TEXT_PLAIN_TYPE);    WebResource resource = Client.create().resource(url);    String response = resource.type(MediaType.MULTIPART_FORM_DATA_TYPE).post(String.class, part);    assertEquals("Hello, World", response);}

三，测试环境：

Server server;@Beforepublic void before() throws Exception {    server = new Server(8080);    server.addHandler(new WebAppContext(WEB_INF_DIRECTORY, "/"));    server.start(); }@Afterpublic void after() throws Exception {    server.stop();}@Testpublic void upload() {    upload("http://localhost:8080/file", "file.txt");}

最后，Maven依赖项：

<dependencies>    <dependency>        <groupId>junit</groupId>        <artifactId>junit</artifactId>        <version>4.8.2</version>        <scope>test</scope>    </dependency>    <dependency>        <groupId>com.sun.jersey</groupId>        <artifactId>jersey-server</artifactId>        <version>1.6</version>    </dependency>    <dependency>        <groupId>com.sun.jersey</groupId>        <artifactId>jersey-client</artifactId>        <version>1.6</version>    </dependency>    <dependency>        <groupId>com.sun.jersey.contribs</groupId>        <artifactId>jersey-multipart</artifactId>        <version>1.6</version>    </dependency>    <dependency>        <groupId>org.mortbay.jetty</groupId>        <artifactId>jetty-embedded</artifactId>        <version>6.1.26</version>    </dependency>    <dependency>        <groupId>commons-io</groupId>        <artifactId>commons-io</artifactId>        <version>2.0.1</version>    </dependency></dependencies>

该

file.txt

Hello, World
