- 完美解决
applica.properties里配置连接数据库使用hikari
#链接数据库
spring.datasource.primary.jdbc-url=jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=utf8 &serverTimezone=Asia/Shanghai
spring.datasource.primary.username=root
spring.datasource.primary.password=root
spring.datasource.primary.driver-class-name=com.mysql.cj.jdbc.Driver
出现的问题异常
Failed to configure a DataSource: ‘url’ attribute is not specified and no embedded datasource could be configured.
未能配置数据源:未指定“url”属性,也无法配置嵌入式数据源。

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
原因:springboot连接数据库是默认的是 :spring.datasource为前缀
解决 配置重定义识别数据库连接方式为spring.datasource.primary
/**
* 使用spring.datasource.hikari为前缀连接数据库
* DataSource 默认为spring.datasource连接
*/
@Configuration
public class Dateresourse {
@Bean(name = "PrimaryDataSource") //作为一个bean对象并命名
@ConfigurationProperties(prefix = "spring.datasource.primary") //配置文件中,该数据源的前缀
public DataSource PrimaryDataSource() {
return DataSourceBuilder.create().build();
}
}
