在spring调用jackson之前获取http post请求主体。

@PostMapping("/your-endpoint")
public void yourControllerMethod(HttpServletRequest request) {
    // 在这里获取HTTP POST请求主体
}

@PostMapping("/your-endpoint")
public void yourControllerMethod(HttpServletRequest request) throws IOException {
    InputStream inputStream = request.getInputStream();
    // 使用输入流进行进一步处理
}

@PostMapping("/your-endpoint")
public void yourControllerMethod(HttpServletRequest request) throws IOException {
    InputStream inputStream = request.getInputStream();
    ObjectMapper objectMapper = new ObjectMapper();
    YourRequestBody requestBody = objectMapper.readValue(inputStream, YourRequestBody.class);
    // 对请求主体进行进一步处理
}
