springboot禁用数据库自动装配

笔者最近在做测试用例(testCase)，但是实际这个测试用例根本需要数据库。启动报错：

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
2020-03-02 21:06:15.808 ERROR 11980 --- [           main] o.s.b.d.LoggingFailureAnalysisReporter   : 

***************************
APPLICATION FAILED TO START
***************************

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 (no profiles are currently active).


Process finished with exit code 1

在网上搜索了一下，找到方法，答案如下：在springboot启动类排除几个类DataSourceAutoConfiguration，DataSourceTransactionManagerAutoConfiguration，HibernateJpaAutoConfiguration

如下

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.boot.autoconfigure.jdbc.DataSourceTransactionManagerAutoConfiguration;
import org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration;
import org.springframework.cache.annotation.CacheConfig;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.scheduling.annotation.EnableAsync;

@EnableAsync
@EnableCaching
@CacheConfig
@SpringBootApplication(scanBasePackages = "com.springboot",exclude = {
        DataSourceAutoConfiguration.class,
        DataSourceTransactionManagerAutoConfiguration.class,
        HibernateJpaAutoConfiguration.class})
public class App 
{
    public static void main( String[] args )
    {
        SpringApplication.run(App.class, args);
    }
}
