SpringBootApplication 无法从新表中获取数据

Question

I have a spring boot application that is working with all the old code. I have added a new table that I am unable to get data from. The rest of the app works just fine. I'm able to login and do things which means the application connects to the database, it's just the new table I can't get data from. I'm adding the code into existing classes (though I want to pull it out if I can get this working).

I added the table manually. And added data to it. I can query the table from the CLI and get results back.

CREATE TABLE Eop_Information (
   id bigint(20) NOT NULL AUTO_INCREMENT,
   employer_als_id varchar(255) NOT NULL,
   sftp_directory varchar(24),
   eop_filename_pattern varchar(16),
   PRIMARY KEY(id),
   FOREIGN KEY (employer_als_id) REFERENCES Employer(employer_als_id)
);

Main class

@SpringBootApplication(exclude = {
    HibernateJpaAutoConfiguration.class
})
@EnableScheduling
public class AlsApp extends SpringBootServletInitializer {

   public static void main(String[] args) {
      SpringApplication.run(AlsApp.class, args);
   }

   @Override
   protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
      return builder.sources(AlsApp.class);
   }
}

My HibernateConfig.

EopInformation class

Service class

Dao class. I added the two methods to see if one would work but neither are getting any results.
