springboot项目启动失败

第一次手动搭建springboot项目,启动失败,遇见问题。启动失败,报错:

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
2018-07-03 13:52:44.978 ERROR 6161 --- [  restartedMain] o.s.b.d.LoggingFailureAnalysisReporter   : 
 
***************************
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).

解决方案是:

这个错误的原因是因为:

 Spring Boot 虽然做了很多默认的配置,但是它没办法知道你用什么数据库,数据库名称、用户名、密码是什么啊。

打开文件“src/main/resources/application.properties”,配置数据库相关信息:

spring.datasource.url=jdbc:mysql://localhost:3306/databaseName?useUnicode=true&zeroDateTimeBehavior=convertToNull&autoReconnect=true
spring.datasource.username=userName
spring.datasource.password=password
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

在 1.5版本的时候可以使用:

spring.datasource.type=org.apache.tomcat.jdbc.pool.DataSource

在2.0版本却不行了。

感觉改动非常大。
