Question

我有这样的代码：

e.isInstance(e1)

我执行这样的@Configuration @ComponentScan @EnableAutoConfiguration public class Application { public static void main(String[] args) { SpringApplication.run(Application.class, args); } @RequestMapping(value = "/foo", method = RequestMethod.POST) String testPost(@RequestParam("param1") String param1, @RequestParam("param2") String param2) { return param1 + param2; } @RequestMapping("/foo") String testGet(@RequestParam String param1) { return param1; } }表达式：

curl

和

curl --verbose http://localhost:9000/foo?param1=Sergei
* Hostname was NOT found in DNS cache
*   Trying 127.0.0.1...
* Connected to localhost (127.0.0.1) port 9000 (#0)
> GET /foo?param1=Sergei HTTP/1.1
> User-Agent: curl/7.35.0
> Host: localhost:9000
> Accept: */*

{"timestamp":1451379356514,"status":404,"error":"Not Found","message":"No message available","path":"/foo"}

请帮助我，让我的方法都有效。

Answer 1

将RestController或Controller刻板印记注释添加到Application类，如下所示：

@RestController
@Configuration
@ComponentScan
@EnableAutoConfiguration
public class Application {
...
}

注意：您可以使用SpringBootApplication元注释而不是这三个，所以您可以：

@RestController
@SpringBootApplication
public class Application {
....
}

Answer 2

您应该将两个控制器方法的范围级别更改为public。现在，他们没有，所以这些方法默认为package local。

public String testPost(@RequestParam("param1") String param1, @RequestParam("param2") String param2) {

public String testGet(@RequestParam String param1) {

RequestMapping Spring REST中的GET和POST方法处理
