java.nio.charset.MalformedInputException: Input length = 1

产生的错误

java.nio.charset.MalformedInputException: Input length = 1

发生的原因

post请求接收数据时,由于对接方发送过来的数据量过大,经过nginx时,被Gzip进行数据流压缩,导致使用InputStream 流读取body数据抛出上述异常

解决方案

配置拦截器

对指定的路径进行拦截器body进行Gzip解压处理

import java.io.IOException;import java.util.Arrays;import javax.servlet.Filter;import javax.servlet.FilterChain;import javax.servlet.ServletException;import javax.servlet.ServletRequest;import javax.servlet.ServletResponse;import javax.servlet.annotation.WebFilter;import javax.servlet.http.HttpServletRequest;import lombok.extern.slf4j.Slf4j;import org.springframework.stereotype.Component;@Component@WebFilter(        filterName = "GZIPFilter",        urlPatterns = {"/test/**"})@Slf4jpublic class GZIPFilter implements Filter {    private static final String[] gzipPath = new String[]{"/test/add"};    public GZIPFilter() {    }    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {        HttpServletRequest req = (HttpServletRequest) request;        String url = req.getRequestURI();        log.info(" url: {}", url);        if (Arrays.asList(gzipPath).contains(url)) {            // 对指定路径下的请求进行gzip解压            chain.doFilter(new GZIPRequestWrapper((HttpServletRequest) request), response);        } else {            chain.doFilter(request, response);        }    }    public void destroy() {    }}

解压

解压gzip
