启动springboot报错 Application run failed

在启动springboot项目通过实体类自动生成表时，报如下错误：

关键点看报错最终原因：

Error creating bean with name 'startUpHandlerImpl': Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: org/apache/commons/lang/ArrayUtils

到项目里找一下是否缺少了有关org.apache.commmons的JAR包，如果找不到如下图： 

就引入改Jar包：

            net.sf.json-lib
            json-lib
            2.4
            jdk15
            
                
                    commons-logging
                    commons-logging
                
            
        
 

 

这就不会报错了，从新启动即可。

注意：我这里不需要引入日志包，故排除了logging
