Answer 1

尝试替换

RequestDispatcher dispatcher = request.getRequestDispatcher("WEB-INF/home.jsp");

通过

RequestDispatcher dispatcher = request.getRequestDispatcher("home.jsp");

因为login.jsp和home.jsp在同一目录中

请改为<li><a href="LoginController" class="first">Home</a></li>

Answer 2

尝试

RequestDispatcher dispatcher = request.getRequestDispatcher("/WEB-INF/home.jsp");

“/”被解释为相对于当前上下文根。
