严重: StandardWrapper.Throwable

当我们再启动的时候发现:



严重: StandardWrapper.Throwable;这样的异常;

这是由于依赖的jar包出现少包或者冲突导致的,

commons的1.0已经用不了;基本上高版本不注意就很容易冲突;

严重: StandardWrapper.Throwable

你会发现类加载错误;因为这个类找不到因为没有这个jar包所以你需要导入jar依赖;

我导入的commons依赖如下:

 
            commons-codec
            commons-codec
            1.9
       
       
   commons-fileupload
   commons-fileupload
   1.3.1
   
    
     commons-io
     commons-io
    
   
  
   

这个io可排除也可不排除,更具情况而定;
