重大发现 springmvc Controller 高级接收参数用法

1.  数组接收

    @RequestMapping(value="deleteRole.json")
    @ResponseBody
    public Object deleteRole(String[] ids){
        return systemService.deleteRole(ids);
    }

页面：

?ids=1&ids=2&ids=3

2. list 接收

ps：

和struts2 的 ognl表达式不同之处在于：

框架	name的值
Struts2	user.roleList[0].id
SpringMVC	roleList[0].id
