unable to create a database schema with mysql and springboot

Question

I'm unable to get spring boot to automatically load my database schema when I start it up.

Here is my application.properties:

spring.datasource.url=jdbc:mysql://localhost:3306/user_details?useSSL=true
spring.datasource.username=
spring.datasource.password=

I set the username and password already.

spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5InnoDBDialect
spring.jpa.generate-ddl=true  
spring.jpa.hibernate.ddl-auto = update

Here is my Application.java:

package com.ecommerce.omazon;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class OmazonApplication {

public static void main(String[] args) {
    SpringApplication.run(OmazonApplication.class, args);
}

}

This is my entity

package net.javaguides.springboot.model;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name = "Users")
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private long id;

    @Column (name = "Username")
    private String Username;
    @Column (name = "Password")
    private String Password;
    @Column (name = "Email")
    private String Email;

public User() {

}
public User(String username, String password, String email) {
    Username = username;
    Password = password;
    Email = email;
}

public long getId() {
    return id;
}
public void setId(long id) {
    this.id = id;
}
public String getUsername() {
    return Username;
}
public void setUsername(String username) {
    Username = username;
}
public String getPassword() {
    return Password;
}
public void setPassword(String password) {
    Password = password;
}
public String getEmail() {
    return Email;
}
public void setEmail(String email) {
    Email = email;
}

}

Everything runs perfectly just when I try to refresh the schema in mysql workbench it is not creating a user file.
