springboot 项目启动后无日志输出直接结束的解决

目录

前景概要报错如下图解决方案以下内容也是因为这个应用名被修改后会出先的问题初始化spring bean 以及 sqlssion解决

前景概要

在这个之前rvice_edu子模块下的功能是没有任何问题，创建了rvice_oss子模块之前失败了很多次，影响到了之前原本正常的rvice_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

解决方案

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

前提是：

这个模块功能再没有新建子模块rvice_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rvice_edu提示初始化spring bean， sqlssion失败，在这个之前rvice_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

把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www.887551.com。
