我试图弄清楚是否可以将JSON对象传递给rest API，或者将多个参数传递给该API？以及如何在Spring中读取这些参数？假设url看起来像以下示例：

例1 http://localhost:8080/api/v1/mno/objectKey?id=1&name=saif

像下面的URL中那样传递JSON对象是否有效？

例2 http://localhost:8080/api/v1/mno/objectKey/{"id":1, "name":"Saif"}

问题：

1）是否可以像在Ex.2中一样将JSON对象传递给url？

2）如何传递和解析示例1中的参数？

我试图编写一些方法来实现自己的目标，但是找不到正确的解决方案？

我试图将JSON对象传递为@RequestParam

http://localhost:8080/api/v1/mno/objectKey?id=1 发生意外错误 (type=Unsupported Media Type, status=415). Content type 'null' not supported

http://localhost:8080/api/v1/mno/objectKey/id=1 发生意外错误 (type=Not Found, status=404). No message available

http://localhost:8080/api/v1/mno/objectKey/%7B%22id%22:1%7D 发生意外错误
(type=Not Found, status=404). No message available

@RequestMapping(value="mno/{objectKey}",
                method = RequestMethod.GET, 
                consumes="application/json")
    public List<Book> getBook4(@RequestParam ObjectKey objectKey) {
        ...
    }

我试图将JSON对象传递为@PathVariable

@RequestMapping(value="ghi/{objectKey}",method = RequestMethod.GET)
    public List<Book> getBook2(@PathVariable ObjectKey objectKey) {
        ...         
    }

我创建了这个对象来保存id参数和其他参数，例如name等。

class ObjectKey{
        long id;
        public long getId() {
            return id;
        }
        public void setId(long id) {
            this.id = id;
        }
    }

@RequestMapping(path = "/mno/objectKey/{id}/{name}", method = RequestMethod.GET)
public Book getBook(@PathVariable int id, @PathVariable String name) {
    // code here
}

@RequestMapping(path = "/mno/objectKey", method = RequestMethod.GET)
public Book getBook(@RequestParam int id, @RequestParam String name) {
    // code here
}

@RequestMapping(path = "/mno/objectKey", method = RequestMethod.POST, consumes = "application/json")
public Book getBook(@RequestBody ObjectKey objectKey) {
    // code here
}
