Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mysqlOrderService' defined in URL [jar:file:/C:/mySoftware/apache-tomcat-6.0.35/webapps/MA_Server1/WEB-INF/lib/MA_Core.jar!/com/sw/plugins/order/service/mysql/MysqlOrderService.class]: Instantiation of bean failed; nested exception is java.lang.ExceptionInInitializerError

引起 Java.lang.ExceptionInInitializerError 错误的原因是：在类的初始化时，出错。也就是说，在加载类时，执行static的属性、方法块时，出错了。

比如

public class AA {

   private static AA aa = new AA(); 

   private AA(){//构造方法

     init();

   }  

 public void init(){

    ....  }

}

初始化类时，会调用init方法，如果Init方法出错，这类初始化失败，就会报java.lang.ExceptionInInitializerError错误

同理，在执行

static{

　　...

}

方法块时，也可能报这个错。

OrderService中一个static变量初始化有问题，去掉这行，重启通过
