真正读取这个配置文件的地方是org.springframework.boot.SpringApplication#getBootstrapRegistryInitializersFromSpringFactories这个时候Spring都还没开始生命周期呢,读取完成后按照key-value的格式存放在缓存中了,只不过在启动时读取要使用 的并不是自动化配置需要的这部分配置Bean而已,在处理Import注解时从缓存读取的String数组...
我认为POGO可以扩展POJO并使用命名参数调用POJO的构造函数,如本例中所示: Java类: public class Pojo { private String name; ... } Groovy类: class Pogo extends Pojo { Pogo() { super(name: 'test name') } } 尝试通过以下方法从JUnit测试实例化Pogo @Test public void shouldInitPojoWithT 浏览3提问...
