Groovy中的json和xml操作

JSON操作

json ->object

final?String?myJSON?=''' {"code":200,"body":{"search_result":[{"id":"1393","name":"東京食尸鬼漫畫","cover_url":"http://img.1whour.com/xpic/東京食尸鬼.jpg","other_1":"","other_2":""},{"id":"2402","name":"東京都立咒術學校漫畫","cover_url":"http://img.1whour.com/xpic/東京都立咒術學校.jpg","other_1":"","other_2":""},{"id":"1107","name":"大東京玩具箱漫畫","cover_url":"http://img.1whour.com/xpic/大東京玩具箱.jpg","other_1":"","other_2":""},{"id":"2026","name":"東京小紅帽漫畫","cover_url":"http://img.1whour.com/xpic/東京小紅帽.jpg","other_1":"","other_2":""},{"id":"879","name":"東京ESP漫畫","cover_url":"http://img.1whour.com/xpic/djESP.jpg","other_1":"","other_2":""},{"id":"2064","name":"東京暗鴉SwordOfSong漫畫","cover_url":"http://img.1whour.com/xpic/東京暗鴉Sword.jpg","other_1":"","other_2":""},{"id":"943","name":"東京烏鴉漫畫","cover_url":"http://img.1whour.com/xpic/東京烏鴉.jpg","other_1":"","other_2":""},{"id":"1954","name":"東京奇跡少年漫畫","cover_url":"http://img.1whour.com/xpic/東京奇跡少年.jpg","other_1":"","other_2":""},{"id":"1106","name":"東京玩具箱漫畫","cover_url":"http://img.1whour.com/xpic/東京玩具箱.jpg","other_1":"","other_2":""},{"id":"430","name":"東京MewMew漫畫","cover_url":"http://img.1whour.com/xpic/0djmm.jpg","other_1":"","other_2":""},{"id":"358","name":"東京80年代漫畫","cover_url":"http://img.1whour.com/xpic/363.jpg","other_1":"","other_2":""}]}} ''' def?jsonSluper?=?new?JsonSlurper() def?object?=?jsonSluper.parseText(myJson) println?object.body.search_result[0]

輸出

[id:1393,?name:東京食尸鬼漫畫,?cover_url: http://img.1whour.com/xpic/ 東京食尸鬼.jpg,?other_1:,?other_2:] 東京食尸鬼漫畫

object -> json

def?cars?=?[new?Car(name:?'qihu',money:?2000), ???????????new?Car(name:?'qq',money:?1000), ???????????new?Car(name:?'haha',money:?3000)] def?json?=?JsonOutput.toJson(cars) println?JsonOutput.prettyPrint(json)

輸出

[{"money":2000,"name":"qihu"},{"money":1000,"name":"qq"},{"money":3000,"name":"haha"}] [????{????????"money":?2000,????????"name":?"qihu"????},????{????????"money":?1000,????????"name":?"qq"????},????{????????"money":?3000,????????"name":?"haha"????}]

xml操作

final?String?xml?=?''' ???? ???????? ???????????? ???????????????? ???????????????????? ????????????????????李剛 ???????????????? ???????????????? ??????????????????? ???????????????????郭林 ??????????????? ??????????????? ??????????????????? ???????????????????任玉剛 ??????????????? ???????????????? ??????????????????? ???????????????????何紅輝 ??????????????? ??????????? ??????????? ??????????????? ??????????????????? ???????????????????李剛 ??????????????? ??????????? ??????? ???? ''' def?xmlSluper?=?new?XmlSlurper() def?resp?=?xmlSluper.parseText(xml) println?resp.value.books[1].book[0].title.text()

輸出

//xmlresp同上? def?list?=?[] resp.value.books.each?{books-> ????books.book.each?{?book?-> ????????def?author?=??book.author.text() ????????if?(author?==?'李剛'){ ????????????list.add(book) ????????} ????} } println?list.toListString()

輸出

[瘋狂Android講義李剛,?Vue從入門到精通李剛]

//深度遍歷 def?titles1?=?resp.depthFirst().findAll?{book?-> ????return?book.author.text()?==?'李剛' } def?titles2?=?resp.depthFirst().findAll?{node?-> ????node.name()?==?'book'?&&?node.@id?==?'2' } println?titles1 println?titles2

輸出

[瘋狂Android講義李剛,?Vue從入門到精通李剛] [第一行代碼郭林]

//廣度遍歷 def?name?=?resp.value.books.children().findAll?{?node-> ????node.name()?==?'book'?&&?node.@id=='2' } println?name

輸出

第一行代碼郭林

Groovy中生成xml用的是MarkupBuilder。例如要生成如下的xml文檔

?Java ?Groovy ?JavaScript ?

def?sw?=?new?StringWriter() def?xmlBuilder?=?new?MarkupBuilder(sw) xmlBuilder.langs(type:?'current',?count:?'3',?mainstream:?'true')?{ ????language(flavor:?'static',?version:?'1.5',?"Java") ????language(flavor:?'dynamic',?version:?'1.6',?"Groovy") ????language(flavor:?'dynamic',?version:?'1.9',?"JavaScript") } println?sw

一般我們生成xml都是用實體對象動態(tài)生成的定義class如下

//對應xml中的Langs結(jié)點 class?Langs?{ ????String?type?=?"current" ????int?count?=?3 ????boolean?mainstream?=?true ????def?language?=?[new?Language(flavor:?"static",?version:?1.5,?value:?"java"), ????????????????????new?Language(flavor:?"dynamic",?version:?1.6,?value:?"Groovy"), ????????????????????new?Language(flavor:?"dynamic",?version:?1.9,?value:?"JavaScript")] } //對應xml中的language結(jié)點 class?Language?{ ????String?flavor ????String?version ????String?value }

def?langs?=?new?Langs() xmlBuilder.langs(type:?langs.type,?count:?langs.count,?mainstream:?langs.mainstream)?{ ????langs.language.each?{?lang?-> ????????language(flavor:?lang.flavor, ????????????????version:?lang.value, ????????????????lang.value) ????} } println?sw

上面的生成方式也是可以的
