这篇博客记录了在Spring Boot应用启动时遇到的错误，问题源于DataSource的配置不正确。报错信息表明无法确定合适的数据库驱动类，并提示缺少`url`属性配置。解决方案包括检查Nacos配置，添加缺失的配置信息，如数据库URL、用户名和密码，以及调整数据源Bean的名称。修复这些问题后，应用应能成功启动。

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 (the profiles dev are currently active).

2 解决方法

1、检查nacos配置，添加对应的配置信息

      clusterclickhouse:
        driver-class-name: ru.yandex.clickhouse.ClickHouseDriver
        url: jdbc:clickhouse://ip:port/dx_data
        username: dev
        password: dev
        validationQuery: SELECT 1

2、检查数据源Bean名称，不能过长
修改前：

    @Bean(name = "clusterClickHouseTemplate")
    public JdbcTemplate clusterClickHouseTemplate(@Qualifier("clusterClickHouseDataSource") DataSource dataSource) {
        return new JdbcTemplate(dataSource);
    }

    @Bean(name = "clusterClickHouseDataSource")
    @Qualifier("clusterClickHouseDataSource")
    @ConfigurationProperties(prefix = "spring.datasource.druid.clusterclickhouse")
    public DataSource clusterClickHouseDataSource() {
        return DruidDataSourceBuilder.create().build();
    }

修改后：

    @Bean(name = "clusterClickHouseTemplate")
    public JdbcTemplate clusterClickHouseTemplate(@Qualifier("clusterChDataSource") DataSource dataSource) {
        return new JdbcTemplate(dataSource);
    }

    @Bean(name = "clusterChDataSource")
    @Qualifier("clusterChDataSource")
    @ConfigurationProperties(prefix = "spring.datasource.druid.clusterclickhouse")
    public DataSource clusterClickHouseDataSource() {
        return DruidDataSourceBuilder.create().build();
    }
