过滤器
----

1. 同时排除一个controller里的多个action

		loginFilter(controller: 'account',action: '*',actionExclude:'(login|logout)'){}


自定义JSON、XML输出
-----
#### 方法一
在BootStrap的init中

    def init = { servletContext ->

        JSON.registerObjectMarshaller( Activity ) { Activity activity ->
            return [
                    id : activity.id,
                    content : activity.content,
                    start : activity.start.format("yyyy-MM-dd HH:mm:ss"),
                    end : activity.end.format("yyyy-MM-dd HH:mm:ss"),
                    allDay:activity.allDay
            ]
        }

    }

#### 方法二
使用Marshaller机制


Controller
----
#### 一个action对应多种格式的请求

    //url : /controller/list?withFormat=html
    //GSP : /[domain]Controller/list.html.gsp

    def list() {
        //默认应该返回当月的 TODO
        def results = Activity.findAll()
        if (null == results) {
            render ''
            return
        }

        withFormat {
            html {
              return [activities: results]
            }
            'json' {
                render results as JSON
            }
        }

    }


显示存在数据库里的图片
----

    def viewCurrentPersonsPortrait(){
            response.setHeader("Content-disposition", "attachment; filename=1.jpg")
            response.contentType = 'image/jpeg' //'image/jpeg' will do too

            Account account = Account.findByName(session['accountName'])
            Person person = account.person

            byte[] bytes = account.person?.portrait

            response.outputStream << bytes //'myphoto.jpg' will do too
            response.outputStream.flush()

    }


    <img src="<g:createLink controller="person" action="viewCurrentPersonsPortrait"/>"/>
