Answer 2

get set 了没值,你看看其他值取道了没,如果取道了就是你opratorInfo这个的问题,如果都没取道,自己找配置文件吧.

Answer 3

只有opratorInfo没有取到，其他都取到了...

Answer 4

重新发布一下  
ognl赋值时
opratorInfo没有实例化

Answer 5

要看完整HTML代码才有结论。主要是opratorInfo.companyName那个控件的代码

Answer 6

opratorInfo实例化问题，没有传值到opratorInfo中，opratorInfo的set方法

Answer 7

    public OpratorInfo getOpratorInfo() {
        if(opratorInfo==null){
             opratorInfo=new OpratorInfo ();
        }
        return opratorInfo;
    }
