Question

在IDE中运行成功 run in IDE

但是打包了一个JAR并使用java -jar运行，运行失败

以下是错误消息

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in class path resource [org/mybatis/spring/boot/autoconfigure/MybatisAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.apache.ibatis.session.SqlSessionFactory]: Factory method 'sqlSessionFactory' threw exception; nested exception is java.lang.IllegalArgumentException: name

当我添加

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

到我的pom.xml，项目可以运行（我的项目不是网络项目）

这是errorDemo includ pom.xml文件 https://github.com/EGo14T/errorDemo

您的问题很有可能是围绕创建spring-boot的“胖” jar。您需要注意，因为它使用了特殊的MANIFEST.MF和专用的spring-boot主类（和类加载器）。您正在使用Maven，因此您可能会使用 Spring Boot Maven插件 （请参见此处：https://www.baeldung.com/executable-jar-with-maven）

MANIFEST.MF示例：

Manifest-Version: 1.0
Main-Class: org.springframework.boot.loader.JarLauncher
Start-Class: org.your.project.Application
Spring-Boot-Version: 1.5.9.RELEASE
Spring-Boot-Classes: BOOT-INF/classes/
Spring-Boot-Lib: BOOT-INF/lib/

SpringBoot（不是Web项目）可以在IDE中运行，但不能与JAR运行
