Get 请求中的 LocalDate 格式 JAVA

Question

我正在为我的 Java MVC 应用编写一个 REST 接口。这是一个函数：

    @GetMapping(value = "/restaurant_representation", produces = MediaType.APPLICATION_JSON_VALUE)
    public RestaurantRepresentation restaurantRepresent(
        @RequestParam(value = "date", required = false) LocalDate date,
        @RequestParam(value = "id") Integer id) {
            return date == null ?
                restaurantRepresentationCompiler.compileRestaurantRepresentation(id, LocalDate.now()) :
                restaurantRepresentationCompiler.compileRestaurantRepresentation(id, date);
    }

现在我正在测试这个，

/rest/admin/restaurant_representation?id=1004

这个请求提供了正确的结果，但是当我尝试添加日期参数时

/rest/admin/restaurant_representation?date=2015-05-05&id=1004

显示的是：

The request sent by the client was syntactically incorrect.

哪种 LocalDate 格式是正确的？

Answer 1

我们需要使用@DateTimeFormat(iso = DateTimeFormat.ISO.DATE)

像这样：

    @GetMapping(value = "/restaurant_representation", produces = MediaType.APPLICATION_JSON_VALUE)
    public RestaurantRepresentation restaurantRepresent(
        @RequestParam(value = "date", required = false) @DateTimeFormat(iso = DateTimeFormat.ISO.DATE) LocalDate date,
        @RequestParam(value = "id") Integer id) {
            return date == null ?
                restaurantRepresentationCompiler.compileRestaurantRepresentation(id, LocalDate.now()) :
                restaurantRepresentationCompiler.compileRestaurantRepresentation(id, date);
}

Answer 2

您需要使用 @DateTimeFormat 并指定您接受的日期格式。

@RequestParam(required = false, value = "date") @DateTimeFormat(pattern="yyyy-MM-dd") LocalDate fromDate
