我有一个控制器,它返回一个覆盖AbstractPdfView
. 效果很好,除了当用户从浏览器保存 PDF 表单时,它会尝试保存请求路径(似乎合理但不是我想要的)。
控制器代码为:
public class MealPlanPDFController {
private MealPlannerDao mealPlannerDao;
private UserDao userDao;
//protected SessionFactory sessionFactory;
@Autowired
public void setMealPlanDao(MealPlannerDao mealPlannerDao) {
this.mealPlannerDao = mealPlannerDao;
}
@Autowired
public void setUserDao(UserDao userDao) {
this.userDao = userDao;
}
@RequestMapping(value = "{id}", method = RequestMethod.GET)
@Transactional
protected ModelAndView handleRequest(@PathVariable Long id, HttpServletRequest request) throws Exception {
System.out.println(request.getContextPath());
ModelAndView modelView = new ModelAndView(new MealPlanPDFView());
MealPlan mealPlan = mealPlannerDao.getMealPlan(id, true);
ServletContext servletContext = request.getSession().getServletContext();
Resource res = new ServletContextResource(servletContext,"/images/logo.png");
URL url = res.getURL();
modelView.addObject("mealPlan",mealPlan);
modelView.addObject("imageURL",url);
System.out.println(url.getPath());
return modelView;
}
}
所以请求路径是:
api/mealplanpdf/1
其中 1 是 MealPlan 的 ID。
在回应我希望它是mealplan_1.pdf
。
说得通?知道我会怎么做吗?
谢谢
