#### ERROR：o.s.b.d.LoggingFailureAnalysisReporter解决办法 ####

*  APPLICATION FAILED TO START

## APPLICATION FAILED TO START ##

Description:
    
    Failed to configure a DataSource: ‘url’ attribute is not specified and no embedded datasource could be configured.
    
    Reason: Failed to determine a suitable driver class
    
    Action:
    
    Consider the following:
    If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
    If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).
    
    Process finished with exit code 1

@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")
    public class UserController {
        
        @GetMapping
        public String getUsers() {
               
            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})
