java - SpringBoot2无法自动配置数据源:未指定“spring.datasource.url”，并且无法自动配置任何嵌入式数据源

我的项目使用springBoot2，并且不需要连接数据库，但是springboot在启动项目时自动配置数据源并引发异常。
我有添加执行，但不起作用

@SpringBootApplication(exclude = { DataSourceAutoConfiguration.class,
        HibernateJpaAutoConfiguration.class
})
@ImportResource("classpath:spring-config-platform.xml")
public class JunoIotPlatformBoot1Application {

    public static void main(String[] args) {
        SpringApplication app = new SpringApplication(JunoIotPlatformBoot1Application.class);
        Map<String,Object> map = new HashMap<>();
        map.put("server.port",8091);
        app.setDefaultProperties(map);
        app.run(args);
    }

因为我将旧的spring项目（xml）合并到springboot项目，所以ImportResource是必需的。

    Description:

    Failed to auto-configure a DataSource: 'spring.datasource.url' is not specified and no embedded datasource could be auto-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).

最佳答案

您应该检查您的构建脚本，看起来那里有一些不需要的启动器（以spring-boot-starter-data-...开头的东西）
