Spring Boot创建DataSource时遇到的错误：No supported DataSource type found

错误信息：

Spring Boot进行DataSource配置错误：No supported DataSource type found

原因：

DataSourceBuilder.create().build() 构建时未在classPath下找到数据源：

private static  MappedDataSourceProperties lookupPooled(ClassLoader classLoader,
				Class type) {
			MappedDataSourceProperties result = null;
			result = lookup(classLoader, type, result, "com.zaxxer.hikari.HikariDataSource",
					HikariDataSourceProperties::new);
		...................
			return result;
		}

解决办法：

pom.xml添加Hikari依赖

	com.zaxxer
	HikariCP

扩展：使用druidDataSource

引入依赖

	com.alibaba
	druid-spring-boot-starter
	1.1.10

示例：

    @Bean(name = "oldOrderDataSource")
    @Qualifier("oldOrderDataSource")
    @ConfigurationProperties(prefix="spring.datasource.old.order")
    public DataSource druidDataSource() {
        return DruidDataSourceBuilder.create().build();
    }

配置：

spring.datasource.druid.url=
