同一个request被读取两次就会发生上面的问题，解决办法是加一个过滤器：
@Configuration
public class ServletRequestConfig implements WebMvcConfigurer {
@Bean
public FilterRegistrationBean filterRegist() {
FilterRegistrationBean frBean = new FilterRegistrationBean();
frBean.setFilter(new XssFilter());
frBean.addUrlPatterns("/*");
return frBean;
}
}
public class XssFilter implements Filter {
public void init(FilterConfig filterConfig) throws ServletException {
}
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
ServletRequest requestWrapper = null;
if(request instanceof HttpServletRequest) {
requestWrapper = new XssRequestWrapper((HttpServletRequest) request);
}
//获取请求中的流如何，将取出来的字符串，再次转换成流，然后把它放入到新request对象中。
// 在chain.doFiler方法中传递新的request对象
if(requestWrapper == null) {
chain.doFilter(request, response);
} else {
chain.doFilter(requestWrapper, response);
}
}
public void destroy() {
}
}
public class XssRequestWrapper extends HttpServletRequestWrapper {
public String _body;
public XssRequestWrapper(HttpServletRequest request) throws IOException {
super(request);
StringBuffer sBuffer = new StringBuffer();
BufferedReader bufferedReader = request.getReader();
String line;
while ((line = bufferedReader.readLine()) != null) {
sBuffer.append(line);
}
_body = sBuffer.toString();
}
@Override
public ServletInputStream getInputStream() {
final ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(_body.getBytes());
return new ServletInputStream() {
@Override
public int read() {
return byteArrayInputStream.read();
}
@Override
public boolean isFinished() {
return false;
}
@Override
public boolean isReady() {
return false;
}
@Override
public void setReadListener(ReadListener listener) {
}
};
}
@Override
public BufferedReader getReader() {
return new BufferedReader(new InputStreamReader(this.getInputStream()));
}
}
