启动 ApplicationContext 时出错。要显示条件报告，请在启用“调试”的情况下重新运行您的应用程序。<SpringBoot>

Question

我从 SpringBoot 开始，我必须做一个 HelloWold 但启用 SSL。我运行我的程序，得到以下结果：

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
2020-06-17 00:01:26.780 ERROR 20620 --- [           main] o.s.boot.SpringApplication               : Application run failed

谁能帮我解决这个问题？

属性：

server.port=8443
server.ssl.enabled=true
server.ssl.key-store= src/main/resources/bootsecurity.p12
server.ssl.key-password=security
server.ssl.key-store-type=PKCS12
server.ssl.key-alias=bootsecurity

主要：

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class DemoController {

    @RequestMapping("getData")
    public String demo() {
        return "Hello SSL";
    }
}

我试图修复它，但我继续遇到同样的错误。我希望有人能帮助我，我真的一直想把它拿走一段时间。我以不同的方式再次这样做了，但总是一样，或者我出现不同的错误。

Answer 1

在您的 application.properties 文件中添加 logging.level.<your-package-name>=DEBUG

like logging.level.com.example=DEBUG -> 使用它你可以在你的项目中启用调试

另外，尝试更改本地主机的端口，也许该端口已经分配了

server.port=8080

Answer 2

我遇到了同样的问题。要修复它，在application.properties（在 src/main/resources）文件中添加属性以更改端口号：server.port=8180

希望对你也有帮助。

Answer 3

好吧，启动 AppContext 时出错可能有很多原因。这是完整的堆栈跟踪吗？

关于您的演示控制器，路径中缺少斜杠“/”并且控制器没有。也许可以解决它，但不能说没有完整的堆栈跟踪。

@RestController("/demo") //<like this
public class DemoController {

    @RequestMapping("/getData") //<-like this
    public String demo() {
        return "Hello SSL";
    }
}
