Jersey Rest webservice重定向到同一页面 [英] Jersey Rest webservice redirecting to the same page
问题描述
我有一个简单的休息网络服务,用于加载页面。一旦页面加载,将显示相同的页面,并显示确认消息或错误信息。
I have a simple rest webservice that will be used to load a page. Once the page is loaded the same page will be displayed with a confirmation msg or error msg being displayed.
我正在使用以下代码加载它....
Im using the using the below code to load it ....
jsp页面: -
jsp page:-
<form action="rest/file/upload" method="post"
enctype="multipart/form-data">
<br> <label>Username:    </label><input type="text"
placeholder="Username" name="username"> <br> <br>
<label>Password:     </label><input type="text"
placeholder="Password" name="password"> <br> <br>
<hr>
<p>
Select a file : <input type="file" name="file" size="45" />
</p>
<br> <input id="submit" type="submit" value="Upload" />
<c:out value="${obj}" />
<!-- ${obj} -->
</form>
控制器
@Path("/file")
public class FileUploadService {
@POST
@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Viewable uploadFile(
@Context HttpServletRequest request,@Context HttpServletResponse response,
@FormDataParam("file") InputStream uploadedInputStream,
@FormDataParam("file") FormDataContentDisposition fileDetail,
@FormDataParam("username") String username,
@FormDataParam("password") String password) throws NoSuchAlgorithmException, IOException, URISyntaxException {
response.setHeader("Location", "/");
return new Viewable("/index.jsp",null);
web.xml
<servlet-mapping>
<servlet-name>jersey-serlvet</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
一旦我点击表格,文件就会被加载并返回到index.jsp页面,但是页面的位置设置为。 RESTFileUpload是程序名称。
Once I click the form the file is loaded and it takes back to the index.jsp page, but the location of the page is set to. RESTFileUpload is the program name.
http://localhost:8080/RESTFileUpload/rest/
但我希望它是
http://localhost:8080/RESTFileUpload/
推荐答案
我不太了解关于MVC功能泽西的(或者说真的任何东西),但另一种选择是使用重定向。你可以简单地使用 Response.seeOther(URI)
。这将使用<$发送303 See Other c $ c>位置标题。浏览器应该发送此页面的另一个请求。该方法可能类似于
I don't know much (or really anything) about the MVC features Jersey, but another option is to just use a redirect. You can simply use Response.seeOther(URI)
. This will send out a "303 See Other" with the Location
header. The browser should send another request for this page. The method might look something like
public Response getRedirect(@Context ServletContext context) {
UriBuilder builder = UriBuilder.fromPath(context.getContextPath());
builder.path("index.jsp");
return Response.seeOther(builder.build()).build();
}
这将重定向到 /contextPath/index.jsp
(或换句话说,位于webapp根目录中的 index.jsp
路径)
This will redirect to /contextPath/index.jsp
(or in other words the index.jsp
path located in the webapp root)
顺便说一句,如果您熟悉Javascript / jQuery,还有其他文件上传选项,不涉及重定向。
As an aside, if you are familiar with Javascript/jQuery at all, there are other file upload options that don't involve the redirect.
只是为了表明这个工作正常
Just to show that this works fine
@Path("/redirect")
public class RedirectResource {
@GET
public Response getRedirect(@Context ServletContext context) {
UriBuilder builder = UriBuilder.fromPath(context.getContextPath());
builder.path("index.html");
return Response.seeOther(builder.build()).build();
}
}
