例外:com.sun.jersey.spi.inject.Errors $ ErrorMessagesException

Question

我正在使用Jersey API进行Web服务.我正在从客户端向服务器发送多部分数据.Web服务开始执行时,我遇到异常.

@POST
@Path("uploadphoto")
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces("text/plain")
public String uploadNotices(@FormDataParam("file") InputStream uploadedInputStream, @FormDataParam("file") FormDataContentDisposition fileDetail) {
    String uploadedFileLocation = "d:/" + fileDetail.getFileName();
    // save it
    try {
        writeToFile(uploadedInputStream, uploadedFileLocation);
    } catch(Exception e) {
        return "no";
    }
    return "yes";
}

// save uploaded file to new location
private void writeToFile(InputStream uploadedInputStream, String uploadedFileLocation) throws Exception {
    OutputStream out = new FileOutputStream(new File(uploadedFileLocation));
    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();
}

Answer 1

您的项目中似乎缺少几个罐子.尝试将这些添加到您的项目中:

球衣,multipart.jar

mimepull.jar

如果您使用的是maven,则可以添加此依赖项:

<dependency>
        <groupId>com.sun.jersey.contribs</groupId>
        <artifactId>jersey-multipart</artifactId>
        <version>1.8</version>
    </dependency>

如果需要,可以更改jar的版本

还要确保你的jersey-multipart jar的版本应该与jersey bundle jar的版本相同

Answer 2

忘记添加@POST或@Get在方法名称之上也会导致此错误

Answer 3

它面临同样的错误,因为具有相同路径名(字符串)的相同@Path注释.

@Path('samepath')   /// samepath cause Jersey Error at run time.
/* Method 1*/

@Path('samepath')
/* Method 2 */
