【问题描述】：

我读过this 和this 主要想法是有人有错误的结构并且组件没有被扫描，我有一个正确的。

我的控制器正在正常初始化。我测试了它调试并在构造函数上设置断点。它正在运行。尽管我的测试、邮递员和浏览器都无法到达端点。我得到一个404。 我正在使用gradle。像this 这样构建我的代码。已经花了 3 个小时试图解决这个问题，但没有成功。

我的控制器看起来像这样。

package com.fressnapf.microservices.orderhistory.controller.impl;

@RestController
@RequestMapping("/customer")
public class OrderHistoryController implements IOrderHistoryController 
    ...
    @Override
    @ResponseStatus(value = HttpStatus.OK)
    @RequestMapping(value = "/customerid/orders", method = RequestMethod.GET, produces = "application/json")
    public String getOrders(@PathVariable("customerid") String customerid, @RequestParam(required = false) String timeFrom,
                        @RequestParam(required = false) String timeTo, @RequestParam(required = false) String openOnly) 
        ...
    

应用类

package com.fressnapf.microservices.orderhistory;

@SpringBootApplication()
@ImportResource("classpath*:applicationContext.xml")
@Configuration()
public class Application 
public static void main(String[] args) 
    ApplicationContext ctx = SpringApplication.run(Application.class, args);

这是我收到的回复

"timestamp": "2020-03-03T16:00:33.489+0000",
"status": 404,
"error": "Not Found",
"message": "No message available",
"path": "/customer/000000000/orders"

这是我在应用程序中获得的日志

【问题讨论】：

你在尝试什么端点？看起来你在 Linux 中；您可以尝试（在应用程序运行的情况下）curl -X GET -H "Accept: application/json" http://localhost:8080/customer/10000001/orders 并粘贴该命令的结果吗？

@x80486 是的，我在 linux 上。 curl 的响应是 "timestamp":"2020-03-03T16:20:17.520+0000","status":404,"error":"Not Found","message":"No message available","路径":"/customer/10000001/orders"

这与我发送的请求基本相同。您可以在问题的“回复”部分看到它。

这很奇怪，它应该可以工作，除非 URL 中有其他内容，我在启动消息中看不到...applicationContext.xml 的内容是什么？顺便说一句，Application 中的@Configuration 什么都不做……你可以删除它。还将您的application.y[a]ml 粘贴到 ../main/resources/` 中。

@x80486 我的项目中没有 application.yamls... 你在哪里看到它们？粘贴在我的 applicationContext 的描述中

【参考方案1】：

如果您复制了控制器代码并将其粘贴到此处... 右括号太多了。我在我的一个控制器上对其进行了测试，它显示了相同的行为。

@RequestMapping(value = "/customerid/orders--><--"...

【讨论】：

天哪！ -_- 。对我来说最尴尬的事情。非常感谢。

是的，其中一个错别字：D。也许使用 spring-boot-actuator 暴露端点以显示所有端点。
