java原裝代碼完成pdf在線預(yù)覽和pdf打印及下載
更新時(shí)間：2017年02月06日 14:29:55 作者：追逐繁星
本文主要介紹了java原裝代碼完成pdf在線預(yù)覽和pdf打印及下載的方法，具有一定的參考價(jià)值，下面跟著小編一起來(lái)看下吧
前提準(zhǔn)備：
1. 項(xiàng)目中至少需要引入的jar包，注意版本:
a) core-renderer.jar
b) freemarker-2.3.16.jar
c) iText-2.0.8.jar
d) iTextAsian.jar
上代碼:
注釋: 此類為自定義的Tag類的基類，在action中怎么放的數(shù)據(jù)，在ftl中就怎么取數(shù)據(jù)，簡(jiǎn)潔明了。

注釋: setConfigParams方法是用于調(diào)用接口定義的配置參數(shù)的方法，如:templateStr，basePath等，doServiceStart，doServiceDoing和doServiceEnd等方法用于處理業(yè)務(wù)邏輯，比如我的需求是做出合同在一個(gè)頁(yè)面顯示，要分頁(yè)，要加水印，但生成的pdf樣式與預(yù)覽的是不同的，所以我加了一個(gè)doServiceDoing中給rootMap添加判斷條件，這樣就能一個(gè)flt文件作出兩種效果(預(yù)覽和打印),當(dāng)然如果預(yù)覽和打印要一樣的效果，doServiceDoing方法可以空實(shí)現(xiàn)。這四個(gè)方法總結(jié)一下就是:
1. setConfigParams ： 配置參數(shù)
2. doServiceStart ： 填充數(shù)據(jù)/條件
3. doServiceDoing : 填充數(shù)據(jù)/條件，到這里是個(gè)分界線，此方法之前，rootMap數(shù)據(jù)先進(jìn)入html再進(jìn)入瀏覽器(預(yù)覽)，此方法之后，rootMap數(shù)據(jù)會(huì)再次進(jìn)入html文件，結(jié)束，所以此處可寫(xiě)判斷
4. doServiceEnd : 可有可無(wú)，我還是寫(xiě)上了，萬(wàn)一哪天的數(shù)據(jù)集太大，此處便可以在數(shù)據(jù)填充完后，清理掉，節(jié)省內(nèi)存空間

注釋: PDFConfigurationInterface 是自定義的標(biāo)簽參數(shù)配置接口，子類必須定義一個(gè)該接口的實(shí)現(xiàn)類的成員變量或定義一個(gè)成員變量?jī)?nèi)部類，并在setConfigParams方法中調(diào)用使其生效。
子類的成員變量接收在tld文件中配置的屬性。
