一：当在eclipse启动spring boot项目时出现问题：

springboot错误: 找不到或无法加载主类

![Center][]

解决办法：

1，通过cmd命令行，进入项目目录进行，mvn clean install 进行编译

![Center 1][]

项目install后，再到eclipse 上选中项目按F5刷新项目。再运行即可问题解决。

2，在eclipse 上选中项目

点击clean 清理项目再运行 问题解决。

![Center 2][]

3，如果运行还是出现无法加载主类，

（a）排查项目代码是否有问题，

（b）可以进入cmd，  cd 进入项目目录

执行命令：

mvn clean compile

mvn install

mvn spring-boot:run

上面三个命令进行编译，启动。

注意：用cmd命令启动要配置好maven环境，jdk环境。

eclipse启动 和cmd命令启动正常界面分别如下图：
