I started learning SpringBoot (using spring sts IDE) and trying to send values from a form & then save them to the database, for now, I have just created a simple form(using JSP) & bean class and checking if localhost shows a fallback error page i.e. page not found because I don't have created any controller to map the JSP page. But I am getting this Error creating bean with name 'entityManagerFactor'
My code:
user.jsp
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<form action="addUsers">
<input type="text" name="id"/><br/>
<input type="text" name="name"/><br/>
<input type="submit"/><br/>
</form>
</body>
</html>
