在JAX-RS资源方法中获取原始请求体 [英] Obtaining raw request body in JAX-RS resource method

问题描述

如何从JAX-RS资源方法访问原始请求正文，如 java.io.InputStream 或 byte [] ？我希望容器绕过特定资源类或方法的任何 MessageBodyReader ，但我在项目中有其他资源应该使用一些 MessageBodyReader 。

How can I access the raw request body from a JAX-RS resource method, as java.io.InputStream or byte[]? I want the container to bypass any MessageBodyReader for a specific resource class or method, but I have other resources in the projects which should be using some MessageBodyReader.

我试过这个，但它会调用已注册的 MessageBodyReader s并且无法将结果分配给 InputStream （与 byte [] 相同的问题）。

I have tried this, but it will invoke registered MessageBodyReaders and fail to assign the result to InputStream (same issue with byte[]).

@POST
public Response post(@Context HttpHeaders headers, InputStream requestBody) {
    MediaType contentType = headers.getMediaType();
    // ... 
}

我也试过这个，但是然后容器无法初始化此错误：

I have also tried this, but then the container fails to initialize with this error:

SEVERE: The following errors and warnings have been detected with resource and/or provider classes:
SEVERE: Missing dependency for method public javax.ws.rs.core.Response SomeResource.post(javax.servlet.http.HttpServletRequest) at parameter at index 0
SEVERE: Method, public javax.ws.rs.core.Response SomeResource.post(javax.servlet.http.HttpServletRequest), annotated with POST of resource, class SomeResource, is not recognized as valid resource method.

@POST
public Response post(@Context HttpServletRequest request) {
    String contentType = request.getContentType();
    InputStream requestBody = request.getInputStream();
    // ... 
}

该方法位于子资源中class，它是从另一个资源类中带有 @Path 注释的方法创建的。

The method is in a sub resource class, which is created from a method with a @Path annotation in another resource class.

我正在使用Jersey 1.11。

推荐答案

只是这可以帮助任何人

public Response doAThing(@Context HttpServletRequest request, InputStream requestBody){


        BufferedReader reader = new BufferedReader(new InputStreamReader(requestBody));
        StringBuilder out = new StringBuilder();
        String line;
        while ((line = reader.readLine()) != null) {
            out.append(line);
        }
        System.out.println(out.toString());   //Prints the string content read from input stream
        reader.close();

        return Response.ok().entity("{\"Submit\": \"Success\"}").build();

    }
