从request中获取参数（参数加body体）

1.get类型参数：
String icode = request.getParameter(“icode”);
2.获取body体

public class RequestBodyUtils {
private static final int BUFFER_SIZE = 1024 * 8;

public static String read(Reader reader) throws IOException
{
    StringWriter writer = new StringWriter();
    try
    {
        write(reader, writer);
        return writer.getBuffer().toString();
    }
    finally{ writer.close(); }
}


public static long write(Reader reader, Writer writer) throws IOException
{
    return write(reader, writer, BUFFER_SIZE);
}


public static long write(Reader reader, Writer writer, int bufferSize) throws IOException
{
    int read;
    long total = 0;
    char[] buf = new char[BUFFER_SIZE];
    while( ( read = reader.read(buf) ) != -1 )
    {
        writer.write(buf, 0, read);
        total += read;
    }
    return total;
}

}

    log.info("开始校验jwt---");
    BufferedReader bufferedReader = request.getReader();
    String bodyStr = RequestBodyUtils.read(bufferedReader);
    log.info("bodyStr:{}",bodyStr);
    String jwt = null;
    try {
        jwt = (String)JSONObjectUtils.parse(bodyStr).get("jwt");
        log.info("jwt:{}",jwt);
    } catch (Exception e) {
        e.printStackTrace();
    }
    String authenticationOfjwt=request.getHeader("jwt");
    if(ObjectUtils.isEmpty(authenticationOfjwt)&&!ObjectUtils.isEmpty(jwt)){
        response.setHeader("jwt",jwt);
        log.info("使用参数里的jwt");
    }
