关于SpringMVC中验证码抛：javax.servlet.S

问题：SpringMVC中，获取验证码，直接使用Response输出流，将验证码图片流直接输出到浏览器。前端能够正常显示验证码图片，但是每次tomcat会抛出：javax.servlet.ServletException: File [validate/getCode.jsp] not found异常。

解决：在验证码Controller方法上，加上@ResponseBody注解，让框架不走视图解析。

• 示例

@RequestMapping(value = "getCode", method = RequestMethod.GET)
    @ResponseBody
    public void getCode() {
        HttpServletResponse response = ToolUtil.getResponse();
        HttpSession session = ToolUtil.getSession();
        Object tmpCaptcha = session.getAttribute(CODE_KEY);
        CircleCaptcha captcha = null;
        if (null != tmpCaptcha) {
            captcha = (CircleCaptcha) tmpCaptcha;
            captcha.createCode();
        } else {
            captcha = CaptchaUtil.createCircleCaptcha(200, 100, 4, 15);
            session.setAttribute(CODE_KEY, captcha);
        }
        log.info("验证码：" + captcha.getCode());
        response.setHeader("Pragma", "no-cache");
        response.setHeader("Cache-Control", "no-cache");
        response.setDateHeader("Expires", 0);
        response.setContentType("image/jpeg");

        try (ServletOutputStream stream = response.getOutputStream()) {
            captcha.write(stream);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

转：关于javax.servlet.ServletException: File [/loginController/getVerifCode.jsp] not found异常 解决方案
