Spring boot Entity Creation | Table Creation

In this tutorial will talk about the Entity Creation. lets discuss what is the entity creation. Entity creation nothing but a table creation.in your core java application your create the database then create the table the same thing in spring called as entity.

Phone No creation  there a rule imagen if you have more than 1 phone no you have to use json format.create a arraylist and use them.i attached the example below.

@Type(type = "json") @Column(name = "contact_numbers",columnDefinition = "json")
 private ArrayList contactNumbers;

in order to use them you have download the corresponding dependencies

go to the google and search  maven vladmihalcea and get the corresponding dependencies.

then paste into your pom.xml

i attached the video below.that will explained every thing.

        this.contactNumbers = contactNumbers;
        this.nic = nic;
        this.activeState = activeState;
    }

    public Employee() {
    }

    public int getCustomerId() {
        return customerId;
    }

    public void setCustomerId(int customerId) {
        this.customerId = customerId;
    }

    public String getCustomerName() {
        return customerName;
    }

    public void setCustomerName(String customerName) {
        this.customerName = customerName;
    }

    public String getCustomerAddress() {
        return customerAddress;
    }

    public void setCustomerAddress(String customerAddress) {
        this.customerAddress = customerAddress;
    }

    public double getCustomerSalary() {
        return customerSalary;
    }

    public void setCustomerSalary(double customerSalary) {
        this.customerSalary = customerSalary;
    }

    public ArrayList getContactNumbers() {
        return contactNumbers;
    }

    public void setContactNumbers(ArrayList contactNumbers) {
        this.contactNumbers = contactNumbers;
    }

    public String getNic() {
        return nic;
    }

    public void setNic(String nic) {
        this.nic = nic;

    }

    public void setActiveState(boolean activeState) {
        this.activeState = activeState;
    }

    @Override
    public String toString() {
        return "Employee{" +
                "customerId=" + customerId +
