Javascript 参数相同、返回类型不同的Spring RESTful-GET方法

我使用

Java/Sprig MVC RESTful应用程序

，客户端使用它。在相同的输入参数和不同的返回类型中，我有2个RESTful方法。方法如下：

// this method should return the `String` 
@RequestMapping(value = "wallets/{currencyName}/{walletName}", method = RequestMethod.GET
            , produces = "text/html")
    public ResponseEntity<String> getAddressWithCurrencyAndWalletName(@PathVariable("currencyName") String currencyName,
                                                                      @PathVariable("walletName") String walletName) {

        logger.info("The currency name is {} and wallet name is {}", currencyName, walletName);
        WalletInfo walletInfo = walletService.getWalletInfoWithCurrencyAndWalletName(currencyName, walletName);

        if (Objects.isNull(walletInfo)) {
            return new ResponseEntity<String>(HttpStatus.NOT_FOUND);
        }

        String address = walletInfo.getAddress();
        return new ResponseEntity<String>(address, HttpStatus.OK);
    }


    // this method should return the `Long` 
    @RequestMapping(value = "wallets/{currencyName}/{walletName}", method = RequestMethod.GET,
            produces = "text/html")
    public ResponseEntity<Long> getWalletIdWithCurrencyAndWalletName(@PathVariable("currencyName") String currencyName,
                                                                     @PathVariable("walletName") String walletName) {

        logger.info("The currency name is {} and wallet name is {}", currencyName, walletName);
        WalletInfo walletInfo = walletService.getWalletInfoWithCurrencyAndWalletName(currencyName, walletName);

        if (Objects.isNull(walletInfo)) {
            return new ResponseEntity<Long>(HttpStatus.NOT_FOUND);
        }

        Long walletId = walletInfo.getId();
        return new ResponseEntity<Long>(walletId, HttpStatus.OK);
    } 

URL

来自

RESTful

方法，我希望它返回

Long

。在这种情况下，我没有什么问题

a。它是否会像相同的

GET

请求可能返回

字符串和
Long
一样工作

b。
数据
已经是
字符串
还是
长
，或者我需要在上面做些什么

显然，我可以像
window.open（“/WalletClient/balance.html？”+“currencyName=“+selectedCurrency+”&“+”walletName=“+walletName”）那样编写它。
但是，在这种情况下，
currencyName
和
walletName
将向用户公开，我更愿意将其隐藏在
URL
中

更新

我将代码更改为容纳一个可选参数，以区分
长
和
字符串

 /**
     * get the wallet address with the currency name and the wallet name
     * 
     * returns the Long value for the walletInfo 
     * curl -i -H "Accept: text/html" http://localhost:8080/rest/wallets/bitcoin/puut | json
     *
     * 
     * returns the String value for the walletInfo address 
     * curl -i -H "Accept: text/html" http://localhost:8080/rest/wallets/bitcoin/puut/true | json
     * 
     * @param currencyName
     * @param walletName
     * @return
     */
    @RequestMapping(value = "wallets/{currencyName}/{walletName}", method = RequestMethod.GET
            , produces = "text/html")
    public ResponseEntity<?> getAddressWithCurrencyAndWalletName(@PathVariable("currencyName") String currencyName,
                                                                 @PathVariable("walletName") String walletName
            , @RequestParam(value = "address", required = false) boolean address) {

        logger.info("The currency name is {} and wallet name is {}", currencyName, walletName);
        WalletInfo walletInfo = walletService.getWalletInfoWithCurrencyAndWalletName(currencyName, walletName);

        if (Objects.isNull(walletInfo)) {
            return new ResponseEntity<String>(HttpStatus.NOT_FOUND);
        }

        // address values is expected 
        if(address){

            String addressValue = walletInfo.getAddress();
            return new ResponseEntity<String>(addressValue, HttpStatus.OK);
        }

        else {
            Long walletId = walletInfo.getId();
            return new ResponseEntity<Long>(walletId, HttpStatus.OK);
        }
    }

现在是否正确？
您可以更改方法并返回
ResponseEntity
类型。
它将是：

@RequestMapping(...)
public ResponseEntity<?> yourMethod(...) {
    // business-logic
    if (some condition) {
        return new ResponseEntity<String>(address, HttpStatus.OK);
    } else if (...) {
        return new ResponseEntity<Long>(walletId, HttpStatus.OK);
    }
}

@RequestMapping（…）
公众反应你的方法（…）{
//业务逻辑
如果（某些条件）{
返回新的响应属性（地址，HttpStatus.OK）；
}否则如果（…）{
返回新的ResponseEntity（walletId，HttpStatus.OK）；
}
}
好主意。如何修改该方法，使其可以说，它通常返回
Long
，除非我提供
布尔值true
，在这种情况下，它将提供
字符串
？是的，您可以添加一个额外的参数，允许选择返回类型或返回Long和String两个值（如果使用简单的DTO对象）.我更新了问题并提供了代码。请看一下好吗？如果在控制器中使用“@PathVariable”，则需要更改客户端代码：var url=“/rest/wallets/”+selectedCurrency+“/”+walletName；太好了，我忘了这件事
var url = "/rest/wallets/?" + "currencyName=" + selectedCurrency + "&" + "walletName=" + walletName;

@RequestMapping(...)
public ResponseEntity<?> yourMethod(...) {
    // business-logic
    if (some condition) {
        return new ResponseEntity<String>(address, HttpStatus.OK);
    } else if (...) {
        return new ResponseEntity<Long>(walletId, HttpStatus.OK);
    }
}
