java获取request body_Java 后台多次获取requestBody

如今越来越多的项目基于Springboot进行开发，在项目中拦截器的使用是不可缺少的，因为需要对body中的值进行校验，例如加密验签、防重复提交、内容校验等等，对于可以多次读取body的解决方案如下：

1 新建HttpRequestWrapperUtil

public class HttpRequestWrapperUtil {

public static String getBodyString(HttpServletRequest request) throws IOException {

StringBuilder sb = new StringBuilder();

InputStream inputStream = null;

BufferedReader reader = null;

try {

inputStream = request.getInputStream();

reader = new BufferedReader(new InputStreamReader(inputStream, Charset.forName("UTF-8")));

String line = "";

while ((line = reader.readLine()) != null) {

sb.append(line);

}

} catch (IOException e) {

e.printStackTrace();

} finally {

if (inputStream != null) {

try
