@RequestBody 空格去除

您可以使用SpringMVC中的过滤器或拦截器来去除@RequestBody中的空格。具体实现可以参考以下代码：

@Component
public class RequestBodyTrimFilter implements Filter {

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        ContentCachingRequestWrapper requestWrapper = new ContentCachingRequestWrapper((HttpServletRequest) request);
        String requestBody = new String(requestWrapper.getContentAsByteArray(), requestWrapper.getCharacterEncoding());        requestBody = requestBody.replaceAll("\\s+", "");
        final byte[] requestBodyBytes = requestBody.getBytes();
        requestWrapper.setContentLength(requestBodyBytes.length);
        requestWrapper.setCharacterEncoding("UTF-8");
        requestWrapper.resetInputStream();
        chain.doFilter(requestWrapper, response);
    }
}
