Java使用IText(VM模版)导出PDF:
public String
createPDF(ProjectManageBase projectManageBase) {

map = new HashMap();// velocity模板中的变量
try {
//模版vm的路径
String tmPath = ServletActionContext.getServletContext()
.getRealPath(“/pdf/vm”);
String pdfPath = ServletActionContext.getServletContext()
.getRealPath(“/pdf”);//用于生成pdf,存放pdf的路径
String facePath = pdfPath + "/test.vm.pdf";// 生成的pdf
//查询数据库的数据
ProjectManageBase projectBase = (ProjectManageBase)
commonDao.findByHql("from ProjectManageBase”).get(0);
map.put("projectBase", projectBase);
Projectjfys jfys = new Projectjfys();
jfys.setLiuShuiHao(projectBase.getLiushuihao());
List<Projectjfys> jfyses =
this.commonDao.findByHql("from
Projectjfys”)
map.put("jfys", jfyses);// 查询经费
//
生成pdf
pdfHandler.createByVelocity(tmPath, PdfConstant.KEPU_FACE,
facePath, map);
