  • 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

    import java.util.List;
    
    public class SystemUser implements Serializable {

    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
