我已经有几天了，尽管我知道他们可能会看到问题的标题重复，但事实是我已经尝试了几种对其他人有用的解决方案，但对我却没有。最可能的是，它真的很傻，我还没有看到它，但是我处于边缘。
这是我的pom.xml

这是我的班级申请
package ar.com.paises;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@SpringBootApplication
@RestController
public class PaisesApplication {
public static void main(String[] args) {
SpringApplication.run(PaisesApplication.class, args);
}
@RequestMapping("/")
String home() {
return "Hello World!";
}
}
这是我的.properties
spring.datasource.username=test
spring.datasource.password=test
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.show-sql = true
spring.jpa.hibernate.ddl-auto = update
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
spring.datasource.url=jdbc:mysql://localhost:3306/test_avantrip?verifyServerCertificate=false&useSSL=false&requireSSL=false
server.port=8083
spring.profiles.active=@spring.profiles.active@
我收到的唯一消息是以下
This is the guide that I was following 有什么建议吗？
更新
@RequestMapping(value="/hi", produces= {MediaType.TEXT_PLAIN_VALUE })
public String home() {
return "Hello World!";
}
什么都没有
更新2
我更改了端口，将其从.properties中删除，并将其保留在8080中，但看不到任何更改。另外，这是我启动时的Spring Boot控制台消息

答案 0 :(得分：0)
尝试删除属性spring.profiles.active=@spring.profiles.active @
答案 1 :(得分：0)
将@RequestMapping("/")移至控制器类，例如：
@RestController
public class Controls {
@RequestMapping("/")
public String home() {
return "Hello World!";
}
}
所以您的主要方法如下：
@SpringBootApplication
public class PaisesApplication {
public static void main(String[] args) {
SpringApplication.run(PaisesApplication.class, args);
}
}
答案 2 :(得分：0)
如果您查看控制台日志，您将不会看到路径“ / hi”未映射，这意味着spring无法找到您的控制器bean。
在映射路径时，您应该在
中看到以下内容RequestMappingHandlerMapping : Mapped "{[/hi],methods=[GET]}".
请将剩余的Controller移到其自己的类中，它可以在同一File中，但将其移到新的不同类中，如下所示：
package ar.com.paises;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@SpringBootApplication
public class PaisesApplication {
public static void main(String[] args) {
SpringApplication.run(PaisesApplication.class, args);
}
}
@RestController
class HiController {
@RequestMapping("/hi")
String home() {
return "Hello World!";
}
}
此外，请确保在部署应用程序时出现与上一个相同的日志。
根据端口调用端点的方式应为：
