@OneToMany(mappedBy = "classes", cascade = CascadeType.ALL, fetch = FetchType.EAGER)
private List<Student> students = new ArrayList<Student>();@OneToMany(mappedBy = "classes", cascade = CascadeType.ALL, fetch = FetchType.LAZY)
private List<Course> courses=new ArrayList<Course>();实体类里面存在多个一对多的关系，针对lazy加载数据时，在取其对象的内容时，报错，不能获取，
如果把lazy修改成eager时，报的错误：
nested exception is org.hibernate.HibernateException: cannot simultaneously fetch multiple bags请问怎样解决可以使他们都不是延迟加载的？
