Struts2中l(wèi)ist轉(zhuǎn)換為json

jar包下載地址

所需jar包，如下圖：

實現(xiàn)代碼，這里以execute方法為例：

@Overridepublic String execute() throws Exception {//1.調(diào)用Service根據(jù)typecode獲得數(shù)據(jù)字典對象listList<BaseDict> list = baseDictService.getListByTypeCode(dict_type_code);//2.將list轉(zhuǎn)換為json格式String json = JSONArray.fromObject(list).toString();//3.設(shè)置json的編碼格式并且將json發(fā)送給瀏覽器ServletActionContext.getResponse().setContentType("application/json;charset=utf-8");ServletActionContext.getResponse().getWriter().write(json);return null;//告訴struts2不需要進行結(jié)果處理}

結(jié)果：

[{"dict_enable":"1","dict_id":"6","dict_item_code":"","dict_item_name":"電話營銷","dict_memo":"","dict_sort":1,"dict_type_code":"002","dict_type_name":"客戶信息來源"},{"dict_enable":"1","dict_id":"7","dict_item_code":"","dict_item_name":"網(wǎng)絡(luò)營銷","dict_memo":"","dict_sort":2,"dict_type_code":"002","dict_type_name":"客戶信息來源"}]

總結(jié)
