Spring boot-JPA generate entity error from existing tables

1
votes

I generated entity class from a existing table made by DBA. columns in the table did not made by alphabetical order. When I start my app, the following error message occured

--Error message--

Error executing DDL table name

There is already an object named table name in the database

--application.properties--

spring.jpa.hibernate.ddl-auto=none spring.jpa.generate-ddl=false

is it possible to create entity class from existing table which columns were not made by alphabetical order? and even if i set ddl-auto=none, my app tried to create new table?

Just have only spring.jpa.hibernate.ddl-auto=none should work and it will not create table as this can have values like create, update, none etc, none mean nothing to do auto update /create/drop

And that is fine if you don’t have alphabetically as long as it’s matches with your entity.

UPDATE

STEP1: Remove mysql connector if you are not using multiple data source

<dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <scope>runtime</scope>
    </dependency>

STEP 2: Add below properties to connect with MS SQL.(replace your db, user, pass, port)

spring.datasource.url=jdbc:sqlserver://localhost;databaseName=springbootdb
spring.datasource.username=sa
spring.datasource.password=Projects@123
spring.datasource.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.jpa.show-sql=true
spring.jpa.hibernate.dialect=org.hibernate.dialect.SQLServer2012Dialect
spring.jpa.hibernate.ddl-auto = none
