PROBLEM : read the (HttpServletResponse response) in the mvc InterCeptor in old version of spring

point 1 : response is having these functions in my version:
———————————————————————————

    String getCharacterEncoding();

    String getContentType();

    ServletOutputStream getOutputStream() throws IOException;

    PrintWriter getWriter() throws IOException;

    void setCharacterEncoding(String var1);

    void setContentLength(int var1);

    void setContentType(String var1);

    void setBufferSize(int var1);

    int getBufferSize();

    void flushBuffer() throws IOException;

    void resetBuffer();

    boolean isCommitted();

    void reset();

    void setLocale(Locale var1);

    Locale getLocale();

    }



    @Override

    }



    @Override

    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {    
            // TODO : try to stroke response in a ring so that I can use it  

    }



 }

POM

<spring.version>3.2.13.RELEASE</spring.version>

1. Code is complex so filter is not working
2. I tried to make my customCachingResponseWrapper but doesn’t work

CustomCachingResponseWrapper

import java.io.ByteArrayOutputStream;

import java.io.IOException;

import java.io.PrintWriter;

import javax.servlet.ServletOutputStream;

import javax.servlet.http.HttpServletResponse;

import javax.servlet.http.HttpServletResponseWrapper;



public class ContentCachingResponseWrapper extends HttpServletResponseWrapper {



    private final ByteArrayOutputStream content = new ByteArrayOutputStream();

    private final ServletOutputStream outputStream = new CachedServletOutputStream(content);

    private PrintWriter writer;



    public ContentCachingResponseWrapper(HttpServletResponse response) {

        super(response);

    }



    @Override

    public ServletOutputStream getOutputStream() throws IOException {

        return outputStream;

    }



    @Override

    public PrintWriter getWriter() throws IOException {

        if (writer == null) {

            writer = new PrintWriter(outputStream);

        }

        return writer;

    }



    @Override

    public void flushBuffer() throws IOException {

        if (writer != null) {

            writer.flush();

        }

        outputStream.flush();

    }



    public byte[] getContentAsByteArray() throws IOException {

        flushBuffer();

        return content.toByteArray();

    }



    private static class CachedServletOutputStream extends ServletOutputStream {

        private final ByteArrayOutputStream content;



        public CachedServletOutputStream(ByteArrayOutputStream content) {

            this.content = content;

        }



        @Override

        public void write(int b) throws IOException {

            content.write(b);

        }



        @Override

        public void write(byte[] b, int off, int len) throws IOException {

            content.write(b, off, len);

        }



    }

}

Solution 1:
——————————————

1. Somehow if we able to create filter then maybe we can achieve it

Solution 2:

1. any other possible solution?
