Java 向RESTAPI发送路径变量

我有一个接受params的控制器

@GetMapping(value = "/messages/getReceivedMessage")
public
HttpEntity<ReceivedMessageDTO> getReceivedMessage(
        @ApiParam(value = "The message ID", required = true) @RequestParam Long id
)

但现在我决定更改RESTAPI地址，它将接受路径变量

@GetMapping(value = "/received/{id}")
public
HttpEntity<ReceivedMessageDTO> getReceivedMessage(
        @ApiParam(value = "The message ID", required = true) @PathVariable Long id
)

@GetMapping（value=“/received/{id}”）
公众的
HttpEntity getReceivedMessage(
@ApiParam（value=“消息ID”，required=true）@PathVariable Long ID
)

如何将路径变量发送到控制器？

我不确定您需要什么，但您所要做的就是使用url调用您的端点，如

“/received/”+someId

或者像角一样

$http.get('/received/' + someId)

希望这有帮助。

将消息id与URL一起传递

http({ url: '/received/' + messageId, method: "GET"}) .then(function (response) { $scope.message = response.data; if(response.data.date_of_read === null) { setDateOfRead(); } }) .catch(function () { console.log('failed'); });

你需要改变

$http({
        url: '/messages/getReceivedMessage',
        method: "GET",
        params: {
            id: messageId
        }
    })

因为，您的参数值成为路径的一部分。

所以在URL angularJS中添加路径变量的问题也是如此？

$http({
        url: '/messages/getReceivedMessage',
        method: "GET",
        params: {
            id: messageId
        }
    })

$http({
        url: '/messages/'+messageId,
        method: "GET"
      })
