java – Ebean @ManyToOne,finder不检索相关对象的所有数据

create table company (
  id                int auto_increment not null primary key,name              varchar(100)
);

create table employee (
  id                int auto_increment not null primary key,name              varchar(100) not null,company_id        int not null,constraint foreign key (company_id) references company (id)
      on delete restrict on update restrict
);

这是Ebean公司的模型

import javax.persistence.Entity;
import javax.persistence.Id;
import com.avaje.ebean.Model;
@Entity
public class Company extends Model
{
    @Id
    public Integer id;
    public String name;
}

和员工模型

@Entity
public class Employee extends Model
{
    @Id
    public Integer id;
    public String name;
    @ManyToOne
    public Company company;

    public static Finder<Long,Employee> find = new Finder<Long,Employee>(Long.class,Employee.class);
}

当我运行以下

Company company = new Company();
company.name = "Microsoft";
company.save();

Employee employee = new Employee();
employee.name = "Mr John";
employee.company = company;
employee.save();

Employee mrJohn = Employee.find.where().eq("id",1).findUnique();
System.out.println(mrJohn.company.id);
System.out.println(mrJohn.company.name);

第一个System.out.println给出1(这是分配给员工的公司的正确ID),但第二个显示为null(我预期应该具有值“Microsoft”),输出为

1
null

因此,问题是为什么只检索公司模型的ID,而不检索其他相关数据？
