日志错误提示：

Failed to execute goal on project manager: Could not resolve dependencies for project test-ssm:manager:pom:0.0.1-SNAPSHOT: Could not find artifact test-ssm:common:jar:0.0.1-SNAPSHOT -> [Help 1]

意思是：

未能在项目管理器上执行目标：无法解析项目测试SSM的依赖项：管理器：pom:0.0.1-快照：找不到项目测试SSM:common:jar:0.0.1-快照->[帮助1]

解决方法：

       在eclipse中选中common项目模块——>右键——>Run As——>Maven install。将common打成jar包。

完成后日志显示如下：

再启动就OK了。
