Cannot forward after response has been committed问题

try {
						PrintWriter out = response.getWriter();
						//输出
						out.print("用户名或密码错误！");
						//out.flush();
						out.close();
						
					} catch (IOException e) {
						e.printStackTrace();
					}

改了之后就是这样了

try {
						PrintWriter out = response.getWriter();
						//输出
						out.print("用户名或密码错误！");
						//out.flush();
						out.close();
						return;//就是这行
					} catch (IOException e) {
						e.printStackTrace();
					}
