@SpringBootApplication定义是个Spring Boot应用；@EnableDiscoveryClient开启Spring Cloud的服务注册与发现，由于这里引入了spring-cloud-starter-alibaba-nacos-discovery模块，所以Spring Cloud Common中定义的那些与服务治理相关的接口将使用Nacos的实现。

这里需要注意：如果直接使用@SpringBootApplication注解，后面不加参数，启动的时候会报错，如下:

经过排查：是因为springboot启动时会自动注入数据源和配置jpa

所以解决方法：

在@SpringBootApplication中排除其注入
@SpringBootApplication(exclude={DataSourceAutoConfiguration.class,HibernateJpaAutoConfiguration.class})

简单的在Controller文件中写一个@RequestMapping(“/login”)打头的

@RestController@RequestMapping("/login")publicclassUserController{@GetMappingpublicStringgetUsers(){return"Hello Spring Security";}}

启动Application之后，无法成功运行，报错o.s.b.d.LoggingFailureAnalysisReporter ERROR；

解决办法：
在Application中将仅仅的@SpringBootApplication修改成：
@SpringBootApplication(exclude={DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class})

@SpringBootApplication(exclude={DataSourceAutoConfiguration.class,HibernateJpaAutoConfiguration.class})
