如何在Spring Boot的main方法中创建一个存储库实例?

Question

我需要在Spring Boot应用程序的主方法中设置SSL属性以启用HTTPS。我的代码是这样的:

import com.our.Task.configuration.FileStorageProperties;
import com.our.Task.entities.ApplicationHttpsSettingsEntity;
import com.our.Task.repository.ApplicationHttpsSettingsEntityRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.ConfigurationPropertiesScan;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.ConfigurableApplicationContext;
import java.util.Properties;
@SpringBootApplication
@EnableConfigurationProperties({FileStorageProperties.class})
public class OurTaskApplication
{
@Autowired
static ApplicationHttpsSettingsEntityRepository applicationHttpsSettingsEntityRepository;
public static void main(String[] args)
{

ApplicationHttpsSettingsEntity applicationsHttpsSettingsEntity = applicationHttpsSettingsEntityRepository.getById(44);
SpringApplication application = new SpringApplication(OurTaskApplication.class);
Properties properties = new Properties();
if (applicationsHttpsSettingsEntity.getUseHttps() > 0)
{
properties.put("server.ssl.key-store", applicationsHttpsSettingsEntity.getKeyStore());
properties.put("server.ssl.key-store-password", applicationsHttpsSettingsEntity.getKeyStorePassword());
properties.put("server.ssl.key-store-type", applicationsHttpsSettingsEntity.getKeyStoreType());
properties.put("server.ssl.key-alias", applicationsHttpsSettingsEntity.getKeyAlias());
}
//        SpringApplication.run(OurTaskApplication.class, args);
application.setDefaultProperties(properties);
ConfigurableApplicationContext ctx = application.run(args);
}
}

它警告我静态方法不允许使用@Autowired。执行时给出空异常。我读过这个不能在Spring Boot应用程序的Main方法中使用@Autowired JPA Repository

但是它没有给我如何做到这一点的任何信息。我不想使用属性文件。

我不会在main方法中做这样的事情。让Spring运行，然后添加你的配置。

我将创建一个runner类，一旦设置了Spring上下文，它将做任何我需要的事情。

的例子:

@Component
@AllArgsConstructor
public class StartRunner implements ApplicationRunner {
/* Add whatever Bean you need here and autowire them through the constructor or with @Autowired */

@Override
public void run(ApplicationArguments args) throws Exception {
// Do whatever you need here inside
}
}
