JSP Cannot forward after response has been committed错误

版权声明：龙人版 https://blog.csdn.net/qq_39021393/article/details/81504976

页面出现

request.getRequestDispatcher("audience.jsp").forward(request, response);语句运行后，没有判断的语句依然在本页执行，若下面依然有请求转发或重定向就会报错

解决方法

---

在每个 request.getRequestDispatcher("audience.jsp").forward(request, response);语句后加一个return;结束本次运行请求转发即可
