Table is not getting Created in mysql schema from Spring boot JPA

Question

I am creating one spring boot application and trying to make a connection with mysql database.

I have created a schema. and trying to add columns in table through spring boot jpa.

Even though my build is geeting passed I am not able to get sucess. I have tried all the possible way fromthe stackover flow but no luck.

Here is my application.properties

spring.datasource.url=jdbc:mysql://localhost:3306/employee_management_system?useSSL=false
spring.datasource.username=root
spring.datasource.password=root

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

And this my model class

package com.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 = "employees")

public class Employee {
    
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private long id;
    
    @Column(name = "first_name")
    private String  fristName;
    
    @Column(name = "last_name")
    private String lastName;
    
    @Column(name = "email_id")
    private String emailId;
    
    public Employee() {
        
    }
    
    public Employee(String fristName, String lastName, String emailId) {
        super();
        this.fristName = fristName;
        this.lastName = lastName;
        this.emailId = emailId;
    }
    
    
    public long getId() {
        return id;
    }
    
    public void setId(long id) {
        this.id = id;
    }
    
    public String getFristName() {
        return fristName;
    }
    
    
    public void setFristName(String fristName) {
        this.fristName = fristName;
    }
    public String getLastName() {
        return lastName;
    }
    public void setLastName(String lastName) {
        this.lastName = lastName;
    }
    public String getEmailId() {
        return emailId;
    }
    public void setEmailId(String emailId) {
        this.emailId = emailId;
    }
}

Answer 1

Need to add createDatabaseIfNotExist=true parameter in datasource URL as shown in below example:

spring.datasource.url=jdbc:mysql://localhost:3306/employee_management_system?createDatabaseIfNotExist=true&useSSL=false

Answer 2

Are you sure your Entity is under the base package or under the sub-package of base-package? If not, then you need to add it to Scan in the main application file:

@EntityScan(basePackages = {"com.springboot.Model"}) 

Try below properties:

spring.jpa.generate-ddl=true <br>
spring.jpa.hibernate.ddl-auto=create

Answer 3

Try adding spring.jpa.defer-datasource-initialization= true in properties file.
