這是轉mht的模板,比起轉html的模板來更加複雜,因為在此我們需要將圖片轉為二進位制格式,base64。可以看下由freemark生成的檔案流

這裡面要注意的一個問題是type=3D\"#_x0000_t75\ 這是一定要加上的不然在2003中能看到圖片,到了2007中就看不到了

應該程式碼很明確了,我再簡單說一下思路,首先從資料庫中獲取帶css樣式的content,並且content包含img,然後利用freemark生成預定的模板,將資料填充進去,而mht是攜帶base64格式圖片的,所以這裡必須進行一個轉碼,然後就可以生成word了,思路應該挺簡單的,就是需要對圖片連結進行一個處理就行了。下一章介紹匯出pdf
