spring cloud微服务启动错误(1)
2019-08-06

今天下午在启动spring cloud微服务的时候,报了这个错误:

Error starting ApplicationContext. To display the auto-configuration report re-run your application with "debug" enabled.2018-07-03 20:17:10.295 ERROR 19024 --- [ main] o.s.b.d.LoggingFailureAnalysisReporter :

***************************APPLICATION FAILED TO START***************************

Description:

Cannot determine embedded database driver class for database type NONE

Action:

If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (no profiles are currently active).

Disconnected from the target VM, address: "127.0.0.1:55393", transport: "socket"

Process finished with exit code 1

刚开始我以为是端口被占用。果断cmd并输入netstat -aon,找半天没发现占用的端口,然后又网上看了一下,

SpringBoot启动报错:Cannot determine embedded database driver class for database type NONE

springboot启动时会自动注入数据源和配置jpa

解决办法一:启动类中加入注解:@SpringBootApplication(exclude={DataSourceAutoConfiguration.class,HibernateJpaAutoConfiguration.class})解决方法二:在Application.properties文件内配置数据源即可。代码如下:

spring.datasource.url=jdbc:mysql://localhost:3306/testspring.datasource.username=rootspring.datasource.password=123456spring.datasource.driver-class-name=com.mysql.jdbc.Driverspring.datasource.max-idle=10spring.datasource.max-wait=10000spring.datasource.min-idle=5spring.datasource.initial-size=5

我仔细的检查了一下,也加了注解,试了一下,我靠,没用啊,人生呐,真是改不完的bedug,

只好用出终极大招,拷贝我自己的代码,删除项目,从新从svn更新项目,导入运行,哎呦我去。怎么还是这问题?难道是我项目配置问题?不对啊,我其他的项目都没有问题啊。束手无策,只好求助小碗(一个认真工作的大佬);

 

通过反复调试,终于找到了。问题所在,pom.xml里面有一个错误的配置,

<dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <scope>runtime</scope> </dependency>

删了就可以运行,微服务也可以注册。配置文件请大家仔细检查。配置文件不对,什么都是扯淡。
