spring boot + spring security 启动错误 Looking for @ControllerAdvice
在运行spring security 源码spring-security-4.2.3.RELEASE\spring-security-4.2.3.RELEASE\samples\boot\helloworld 中的例子时，能正常显示login页面，但是把包的名字修改了之后，就不能跳到自定义的login页面了，而是跳到了spring security 默认的登录页面，原因是、
SpringBoot在写启动类的时候如果不使用@ComponentScan指明对象扫描范围，默认指扫描当前启动类所在的包里的对象，如果当前启动类没有包，则在启动时会报错：Your ApplicationContext is unlikely to start due to a @ComponentScan of the default package错误。因为启动类不能直接放在main/java文件夹下，必须要建一个包把它放进去或者使用@ComponentScan指明要扫描的包。代码示例如下：
@SpringBootApplication
@ComponentScan
(basePackageClasses＝MytestApplication.class)
public
class
MytestApplication
{
public
static
void
main(String[] args){ SpringApplication.run(MytestApplication.class, args); }}
