好的，你想将GET请求改为多个参数的请求方式。可以使用@RequestParam注解来接收多个参数，具体代码如下： ```java @RestController @RequestMapping("/books") public class BookController { @GetMapping("/search") public String search(@RequestParam String keyword, @RequestParam int page, @RequestParam int size) { System.out.println("search books with keyword: " + keyword + ", page: " + page + ", size: " + size); return "search books with keyword: " + keyword + ", page: " + page + ", size: " + size; } } ``` 这里我们将原来的`@GetMapping`注解改为了`@GetMapping("/search")`，表示我们要在/books路径下添加一个/search的子路径，用于接收多个参数。同时我们在方法参数中加入了三个`@RequestParam`注解，用于接收名为`keyword`、`page`和`size`的三个参数。在方法体中，我们使用参数拼接出一句话，用于返回给客户端。这样，当访问http://localhost:8080/books/search?keyword=spring&page=1&size=10时，就可以调用search方法，打印出如下信息： ``` search books with keyword: spring, page: 1, size: 10 ``` 同时返回给客户端： ``` search books with keyword: spring, page: 1, size: 10 ```
