这个注册
@WebServlet(urlPatterns = "/addUser")
public class RegisterServlet extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
System.out.printf("1111111111111");
}
@Override
protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
req.setCharacterEncoding("utf-8");
String jsonRegistration = RequestUtil.getRequestBody(req);
Gson gson = new Gson();
JsonObject jsonObject = new JsonParser().parse(jsonRegistration).getAsJsonObject();
String username = jsonObject.get("username").getAsString();
String password = jsonObject.get("password").getAsString();
resp.setContentType("application/json");
BaseResponse[I] baseResponse = new BaseResponse[I]();
boolean registrationSuccess = AdminDao.insertAdministrator(username, password);
if (registrationSuccess) {
baseResponse.setCode(200);
baseResponse.setMsg("注册成功");
resp.sendRedirect(req.getContextPath() + "/login.jsp");
} else {
baseResponse.setCode(500);
baseResponse.setMsg("注册失败，请重试");
}
PrintWriter out = resp.getWriter();
out.print(gson.toJson(baseResponse));
out.flush();
out.close();
}
}
前端就 layui'
就是进不了这个放 addUser 打断也调试了看不出问题
