Spring boot请求参数

GET请求:

1.restful风格:

@GetMapping("/order/detail")
public BaseOutput omsQueryDetail(@RequestParam("orderId") String id) {
}

2.resultful风格:

@GetMapping("/order/detail/{orderId}")
public BaseOutput omsQueryDetail(@PathVariable String orderId) {
}

POST请求:

@PostMapping("/order/detail")
public BaseOutput orderDetail(@RequestBody OrderDetailReq req) {
}

一些情况:

1.使用@RequestParam,参数不一定存在时

@RequestParam(name="id",required=false)

@RequestParam(name="id",required=false,defaultValue="0")
