我們在制作單證或報表時，客戶經常要我們把最后的合計數轉寫中文大寫金額。這個需求很合理，但感覺并不容易實現，如何在JasperReport中加入大寫金額的實現呢？提供一種實現的方法給大家參考。
實現思路：
在報表執行過程中使用scirptlet將存放著數字金額的變量讀出轉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果,是不是很酷呀?
差點忘記了關鍵的啦,要在你的報表XML中jasperReport節點中增加以下屬性值scriptletClass="TransChineseMoneyScriptlet" ,來啟用該scriptlet
