Spring MockMVC如何模拟@RequestParam-Date类型

Question

我有一个代码要测试，如下所示：

@RequestMapping(value = "/prepareLic", method = {RequestMethod.GET})
    public @ResponseBody
    String prepareLice(HttpServletRequest request, @RequestParam String test1, @RequestParam String test2, @RequestParam String test3, @RequestParam String test4, @RequestParam Date liPrintDate, @RequestParam String test5, @RequestParam String test6, @RequestParam String test7) throws NSException, SQLException, ParseException {
      ...
        return new Gson().toJson(jsonResponse);
    }

单元测试定义如下：

   mockMvc.perform(get("/prepareLic").param("test1", "12").param("test2" ,"cpomName").param("test3", "123").param("test4", "signeeName").
            param("liPrintDate", "22/09/2015").param("test5", "12").param("test6", "O2").param("test7", "12")).andDo(print())
            .andExpect(status().isOk()
            );

当我执行上述单元测试时，显示以下错误：

触发异常是因为liPrintDate是一个日期对象，但在上面的测试中，它被定义为String。

由于.param只接受String，我如何在上面的单元测试中将liPrintDate定义为Date？

提前谢谢你的建议。

尝试定义RequestParam 的日期格式

@RequestMapping(value = "/prepareLic", method = {RequestMethod.GET})
    public @ResponseBody
    String prepareLice(HttpServletRequest request, @RequestParam String test1, 
    @RequestParam String test2, @RequestParam String test3, @RequestParam String test4, 
    @RequestParam @DateTimeFormat(pattern="dd/MM/yyyy") Date liPrintDate, 
    @RequestParam String test5, @RequestParam String test6, @RequestParam String test7) 
        throws NSException, SQLException, ParseException {
      ...
        return new Gson().toJson(jsonResponse);
    }
