1.獲取連接中的參數,使用倒的關鍵詞@PathVariable
@RestController
public class HelloController {@RequestMapping(value = "/hello/{id}",method = RequestMethod.GET)public String index(@PathVariable("id") Integer id){return "id="+id;}} 啟動項目訪問，成功獲取到id
也可以把id放在/hello前面
public class HelloController {@RequestMapping(value = "/{id}/hello",method = RequestMethod.GET)public String index(@PathVariable("id") Integer id){return "id="+id;}}?
2.傳統的問號(?id=110)傳值，設置id可以不傳默認值為0，使用倒的關鍵詞@RequestParam
public class HelloController {@RequestMapping(value = "/hello",method = RequestMethod.GET)public String index(@RequestParam(value = "id" ,required = false, defaultValue = "0") Integer id){return "id="+id;}}不傳參數默認為0
傳參數為獲取到的參數
?
