Spring Boot笔记-设置拦截器为false时返回的Body

Posted 2021-06-16 IT1995

以preHandle拦截器为例：

@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler

这里的HttpServletResponse类中可以调用getWriter()获取PrintWriter直接将数据写到body中，如下

protected void setHttpJsonBody(ResponseData data, HttpServletResponse response) throws IOException {

    response.setContentType("application/json; charset=utf-8");
    PrintWriter writer = response.getWriter();
    writer.print(JSONObject.toJSONString(data));
    writer.close();
    response.flushBuffer();
}
