java - spring-boot-2.0.0.RELEASE 中缺少 SpringApplication.run 的特定重载

Question

我需要将应用程序从 spring-boot-1.2.5.RELEASE 升级到 spring-boot-2.0.0.RELEASE。

我有以下代码:

@Configuration
@ComponentScan
@EnableAutoConfiguration(exclude = {HibernateJpaAutoConfiguration.class, RedisAutoConfiguration.class})
public class NiceBootApplicationWithoutDB extends AbstractBootApplication {

    public static final String APPLICATION_CONTEXT_XML = "classpath:/META-INF/application-context-nodb.xml";

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

}

SpringApplication.run(APPLICATION_CONTEXT_XML, getFullArgList(args)) 的重载是:

/**
 * Static helper that can be used to run a {@link SpringApplication} from the
 * specified source using default settings.
 * @param source the source to load
 * @param args the application arguments (usually passed from a Java main method)
 * @return the running {@link ApplicationContext}
 */
public static ConfigurableApplicationContext run(Object source, String... args) {
    return run(new Object[] { source }, args);
}

/**
 * Static helper that can be used to run a {@link SpringApplication} from the
 * specified sources using default settings and user supplied arguments.
 * @param sources the sources to load
 * @param args the application arguments (usually passed from a Java main method)
 * @return the running {@link ApplicationContext}
 */
public static ConfigurableApplicationContext run(Object[] sources, String[] args) {
    return new SpringApplication(sources).run(args);
}

这两个重载在 spring-boot-2.0.0.RELEASE 中都不存在。

我的问题是-如何升级上面的代码？

Answer 1

你是对的:Spring Boot 版本 2 中 SpringApplication 类的 API 没有提供等价的 API。
所以没有直接的方法来提供 XML Spring 配置文件。

根据这个answer ，您可以使用 @ImportResource 注释您的 Spring Boot 类.

@ImportResource("classpath:/META-INF/application-context-nodb.xml")

它的工作方式与 @Import 相同，但它导入 XML spring 配置文件而不是类文件。

Javadoc 信息:

Indicates one or more resources containing bean definitions to import.

Like @Import, this annotation provides functionality similar to the element in Spring XML. It is typically used when designing @Configuration classes to be bootstrapped by an AnnotationConfigApplicationContext, but where some XML functionality such as namespaces is still necessary.
