Using @Table Hibernate

How do I use the annotation @Table of Hibernate using a variable that brings the table name for example @Table(name = "dep4"+Dados.getCodEmp)? 'Cause I’m using it that way but I was presented with the following mistake:

The value for annotation attribute Table.name must be a constant expression

I need this because in the database of the system in question the tables are generated with the following prefix nomenclature + the code assigned to the company, for example dep4+(CodEmp). This code I take from a text file that is inside the application directory.

java mysql hibernate table

  • I can do one thing, but I don’t understand this "dep4"+Dados.getCodEmp. Is that the table name or would it be a "prefix"? Type: ("dep4"+Dados.getCodEmp) + "_nome_da_tabela"

  • The "dep4"+Data.getCodEmp would be the name of my table, where the dep4 is the default prefix of the table name Data.getCodEmp is where I get the company code to compose the table name. For example I am logged in to the bank with the code company 01 then the name of my table would be dep401

  • Oh yes, the solution I had as a suggestion was for another purpose. You can generate the names dynamically, but not by annotating @Table: https://stackoverflow.com/a/1507980/4056678

I’m afraid I can’t do this.

@Table is a Java annotation, and Java annotations cannot receive values in time from Runtime. Java annotations can only receive constants, as the error message informed you.

You must create a Generating Database Schemas or Interceptors for the schemed your database. 

public class Main {

   public static void main(String[] args) {
     Persistence.generateSchema("samplePU", null);
   }
}
