解决Exception in monitor thread while connecting to server localhost:27017异常，禁用MongoDB

Springboot默认启用MongoDB，如果没有集成MongoDB在启动项目时会抛出异常：Exception in monitor thread while connecting to server localhost:27017；

只需要在启动类中修改注解：

将注解：

@SpringBootApplication

改为

@SpringBootApplication(exclude = {MongoAutoConfiguration.class, MongoDataAutoConfiguration.class})

即可禁用springboot自带的mongodb配置，项目启动正常。

修改前：

@Slf4j
@SpringBootApplication //默认启动mongodb
public class JeecgSystemApplication extends SpringBootServletInitializer {
}

修改后：

@Slf4j
@SpringBootApplication(exclude = {MongoAutoConfiguration.class, MongoDataAutoConfiguration.class})
public class JeecgSystemApplication extends SpringBootServletInitializer {
}
