springboot 项目启动后无日志输出直接结束的解决

前景概要

  • 在这个之前service_edu子模块下的功能是没有任何问题,
  • 创建了service_oss子模块之前失败了很多次,影响到了之前原本正常的service_edu模块的pom.xml
  • 链接: IDEA创建Maven项目一直显示正在加载的问题

不用弄清楚来龙去脉,看你的错误是否符合 如下效果图

报错如下图

在这里插入图片描述

解决方案

在这里插入图片描述

  • target目录删除掉,再用mvn clean 方式清理一次该maven子工程
  • target目录删除掉,再用mvn clean 方式清理一次该maven子工程

以下内容也是因为这个应用名被修改后会出先的问题

没有遇到可以忽略

初始化spring bean 以及 sqlsession

前提是:

这个模块功能再没有新建子模块service_oss没有任何功能错误,但是启动时候出现如下报错

解决

这个service_edu提示初始化spring bean, sqlsession失败,在这个之前service_edu子模块下的功能是没有任何问题,检查这个子模块的依赖

检查 该工程模块的依赖关系,剪切pom.xml配置重新粘贴导入

target目录删除掉,再用mvn clean 方式清理一次该maven子工程

以上为个人经验,希望能给大家一个参考,也希望大家多多支持云海天教程。
