我的项目使用springBoot2，并且不需要连接数据库，但是springboot自动配置数据源并在启动项目时抛出异常。 我已经添加了执行，但它不起作用
@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 项目中，所以 ImportResource 是必要的。 日志是:

APPLICATION FAILED TO START

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，看起来您有一些不需要的启动器(以 spring-boot-starter-data-... 开头的东西)
