Question

JDBC是必需的，但无需使用jdbc

我一直在为我的春季项目编码。这是我的配置：-main类

@SpringBootApplication(
        scanBasePackages ={"src.tl_client"}
)
public class Application   extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(Application.class);
    }

    private static SpringApplicationBuilder configureApplication(SpringApplicationBuilder builder) {
        return builder.sources(Application.class).bannerMode(Banner.Mode.OFF);
    }

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

您将需要从应用程序中排除DataSourceAutoConfiguration。

@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
public class App{
    public static void main(final String[] args){
        SpringApplication.run(App.class, args);
    }
}
