Question

我正在运行基于 java spring 引导框架的应用程序。 基本上我有不止一个微服务，我希望它们使用 http rest 进行通信。 但得到这个错误。 你能帮我解决这个错误吗？

Answer 1

从代码中，您似乎正在尝试根据客户 ID 检索帐户。 在这种情况下，它将是 @GetMapping 而不是 @PostMapping（在第 12 行）。 此外，在获取的情况下，我们在 url 中传递变量，而不是在请求正文中。 作为一种编码习惯，className 应该以大写字母开头（方法的返回类型应该是 Account 而不是 accounts）

@GetMapping("/myAccount/{id}


public Account AccountsGetAccountDetails(@PathVariable String id ) {}
