我有一个Spring Boot项目,可以在IntelliJ中成功运行,但是当我打包成可执行的jar文件后,无法再运行。以下是异常的堆栈跟踪:

我的配置大致如下:
@Configuration
@EnableAutoConfiguration
public class AppConfig {
... some beans
}
按照43.2 查找自动配置的位置描述,在项目资源文件夹下添加META-INF/spring.factories
文件。但是这并没有解决问题:
org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
el.dorado.AppConfig
这里是项目的pom.xml

@EnableAutoConfiguration
,以便让Boot首先扫描这个AppConfig
。 - chrylis -cautiouslyoptimistic-@EnableAutoConfiguration
。请查看您引用的文档。其次,看起来您正在尝试在没有spring-boot-autoconfigure
的情况下运行应用程序。没有找到spring.factories
,因此您的构建未正确打包它。请分享一个可以重现问题的项目。 - Stephane Nicoll@EnableAutoConfiguration
来配置其他bean(例如JPA)。我已经使用项目的pom.xml
更新了问题。此外,当我使用jar tf jar-file
检查生成的jar时,我实际上看到META-INF/spring.factories
存在,所以我想构建已经正确打包! - bachrMETA-INF/spring.factories
呢? - Stephane Nicoll
