如何从em.find方法中获取相同的实体？

Address address=em.find(Address.class,1);
System.out.println("Name of Address: "+address.getAddressName);   // Chinnur
address.setAddressName("Russia");
Address address1=em.find(Address.class,address.getAddressId());
System.out.println("Name of Address: "+address1.getAddressName); //?????????

我需要address1.getAddressName的是“chinnur”，

但我得到 address1.getAddressName的是“俄罗斯”

我需要简短的解释，请帮助我。

修改后的实体存储在事务中cache，当您想再次检索时显示缓存结果
