SpringMVC之Controller

传递参数

方式一

@GetMapping(value = "/get/{id}")
public Result getUser(@PathVariable Long id) {
    return "hello";
}

方式二

post或get均可

@PostMapping(value = "/add")
public Result addUser(@RequestParam("username") String username,
                      @RequestParam("name") String name) {
    return "hello";
}

方式三

@PostMapping(value = "/add")
public Result addUser(@ModelAttribute("userInfo") UserInfo userInfo) {
    return "hello";
}

注：在fiddler中模拟post无效时，添加

Content-Type: application/x-www-form-urlencoded
