前臺請求參數與後臺方法參數一致與不一致的狀況

1. 函數參數名與請求參數名保持一致

@RequestMapping("/delete")
@ResponseBody
public JsonResult delete(Long id){


2. 函數參數名與請求參數名保持不一致

@RequestMapping(value = "/add", method = RequestMethod.POST)//參數是對象
public AjaxResult save(@RequestBody Product product) {

@RequestMapping(value = "/delete/{id}", method = RequestMethod.DELETE)
public AjaxResult delete(@PathVariable("id") Long id) {

@RequestMapping(value = "/{id}", method = RequestMethod.GET)
public Product get(@PathVariable(value = "id", required = true) Long id)

 @RequestMapping(value = "/redis",method = RequestMethod.POST)
 @Override
 public void set(@RequestParam("key") String key,@RequestParam("value") String value){
 RedisUtil.set(key,value); }
