@lihengming 帮忙看一下

[lihengming]

在这里只是配置数据源，这时候数据源还没有被初始化呢，肯定报错了，你注入一个数据源再试试。另外，单数据源是默认进行自动配置的，不需要你自己再在这里配置，不知道你的用意是什么？

@lihengming 大神怎么禁用自动配置啊， 我用的springcloud， 但是有些服务节点不需要连数据库

[longxiaonan]

我一个个试的，exclude了很多个类， 但是还是会自动配置，我的配置如下： `@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class, DruidDataSourceAutoConfigure.class, DataSourceTransactionManagerAutoConfiguration.class, DataSourceHealthIndicatorAutoConfiguration.class, MongoAutoConfiguration.class, MongoDataAutoConfiguration.class})//禁用mongo自动配置 //@SpringBootApplication(exclude= {DataSourceAutoConfiguration.class}) @EnableDiscoveryClient public class TestApplication {

public static void main(String[] args) {
    SpringApplication.run(TestApplication.class, args);
}

}`
