}

add below line after @entity.

@table(name="rulequestion") 

the @table annotation allows specify details of table used persist entity in database.

the @table annotation provides 4 attributes, allowing override name of table, catalogue, , schema, , enforce unique constraints on columns in table. using table name employee.

also add

  @id     @generatedvalue     @column(name = "id")     private integer  id; 

i have class generate table

@entity @table(name = "transaction") public class transaction {      @id     @generatedvalue     @column(name = "id")     private integer  id;      @column(name="ocpp_start_tag_id",nullable=false)     private string ocppstarttagid;  }
