你的后台Action可能有问题，前台页面JSP是正确的。我后台用SpringMVC返回的，示例代码：

 @RequestMapping(value="/getList")
    @ResponseBody
    public List getList(String suoshubumen){
        List<Person> list = new ArrayList<Person>();
        if("销售部主管".equals(suoshubumen)){
            list.add(new Person("z1","1"));
            list.add(new Person("z2","1"));
            list.add(new Person("z3","1"));
            list.add(new Person("z4","1"));
        }else if("顾问1部".equals(suoshubumen)){
            list.add(new Person("w1","1"));
            list.add(new Person("w2","1"));
            list.add(new Person("w3","1"));
            list.add(new Person("w4","1"));
        }else{
            list.add(new Person("r1","1"));
            list.add(new Person("r2","1"));
            list.add(new Person("r3","1"));
            list.add(new Person("r4","1"));
        }

        return list;
    }
