Springboot在idea运行正常，打包jar后报错

Question

SpringBoot在IDEA中可以正常运行，但是打包成jar后在Linux服务器上运行报错（已安装java开发环境）【附错误信息及pom.xml配置】：

[root@iZbp16dxhryrj2krm6p2hzZ after]# java -jar eatapp.jar

Answer 1

参考通义千问和郭老师的小迷弟雅思莫了-编写提供，主要是为了帮助您快速解决问题，如下回答，您可以参考下，如有问题，评论区留言。

根据提供的错误信息，Spring Boot在运行时无法初始化userMapper bean，因为它缺少必要的属性'sqlSessionFactory'或'sqlSessionTemplate'。MyBatis-Plus需要这两个属性来与数据库进行交互。

在您的Spring Boot应用中使用MyBatis-Plus时，您需要确保正确配置了SqlSessionFactory Bean。通常，您需要在配置类中添加如下的代码：

@Configuration
public class MybatisPlusConfig {

    @Autowired
    private DataSource dataSource;

    @Bean
    public SqlSessionFactory sqlSessionFactory() throws Exception {
        SqlSessionFactoryBean factoryBean = new SqlSessionFactoryBean();
        factoryBean.setDataSource(dataSource);
        // 其他可能的配置...
        return factoryBean.getObject();
    }
}

同时，请确保数据源（DataSource）已正确配置并注入到Spring容器中。如果使用的是Spring Boot的自动配置，那么只需要在application.properties或application.yml文件中配置好数据库连接信息即可，例如：

spring.datasource.url=jdbc:mysql://localhost:3306/your_database
spring.datasource.username=your_username
spring.datasource.password=your_password
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

检查一下这些配置是否存在于打包后的jar文件对应的配置文件中，并且配置正确无误。
