SpringBoot - MySQL - mysql

Question

I have created a Spring Boot REST API with inbuilt Apache Derby database. It worked fine. Now I have to integrate it with MySQL. I have updated POM.XML and configured the driver.
Expense.java
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 = "vendor")
public class Expense {
#Id
#Column
#GeneratedValue(strategy = GenerationType.IDENTITY)
private String vendorId;
#Column
private String vendorName;
#Column
private int vendorPhone;
#Column
private int vendorBalance;
#Column
private int vendorChequeAmount;
public String getVendorId() {
return vendorId;
}
public void setVendorId(String vendorId) {
this.vendorId = vendorId;
}
public String getVendorName() {
return vendorName;
}
public void setVendorName(String vendorName) {
this.vendorName = vendorName;
}
public int getVendorPhone() {
return vendorPhone;
}
public void setVendorPhone(int vendorPhone) {
this.vendorPhone = vendorPhone;
}
public int getVendorBalance() {
return vendorBalance;
}
public void setVendorBalance(int vendorBalance) {
this.vendorBalance = vendorBalance;
}
public int getVendorChequeAmount() {
return vendorChequeAmount;
}
public void setVendorChequeAmount(int vendorChequeAmount) {
this.vendorChequeAmount = vendorChequeAmount;
}
public Expense(String vendorId, String vendorName, int vendorPhone, int vendorBalance, int vendorChequeAmount) {
super();
this.vendorId = vendorId;
this.vendorName = vendorName;
this.vendorPhone = vendorPhone;
this.vendorBalance = vendorBalance;
this.vendorChequeAmount = vendorChequeAmount;
}
application.properties
server.port = 8087
server.contextPath=/expense-tracker
spring.datasource.url=jdbc:mysql://localhost:3306/web_customer_tracker
spring.datasource.username=springstudent
spring.datasource.password=springstudent
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update
spring.jpa.hibernate.naming.implicit-strategy=org.hibernate.boot.model.naming.ImplicitNamingStrategyLegacyHbmImpl
spring.jpa.hibernate.naming.physical-strategy=org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy
Please click for the MySQL details
When I run using Postman, I am getting 404 error. Something is wrong with MySQL configuration. Please help to identify it. Thanks
