我們在制作單證或報表時，客戶經(jīng)常要我們把最后的合計數(shù)轉(zhuǎn)寫中文大寫金額。這個需求很合理，但感覺并不容易實現(xiàn)，如何在JasperReport中加入大寫金額的實現(xiàn)呢？提供一種實現(xiàn)的方法給大家參考。
實現(xiàn)思路：
在報表執(zhí)行過程中使用scirptlet將存放著數(shù)字金額的變量讀出轉(zhuǎn)換成大寫金額字符串后放入大寫金額變量中。報表即可象顯示普通字符變量一樣顯示大寫金額。

后面幾個方法都是iReport所需的幾個方法，不要刪除掉它。
然后在報表中將定義兩個報表變量:
sumTaxMoney 用于存放小寫金額,它是Double型,并在iReport中寫上計算公式或script
cnMoney 用于接收本scriptlet傳回的大寫金額變量,在iReport中無需賦值,直接放到需顯示的地方即可
用紅框框起來的部分就是我們想要的結(jié)果,是不是很酷呀?
差點忘記了關(guān)鍵的啦,要在你的報表XML中jasperReport節(jié)點中增加以下屬性值scriptletClass="TransChineseMoneyScriptlet" ,來啟用該scriptlet
