我正在使用 Spring 3.1.2，并且可以使用 JAR 文件在 k8s 集群中成功部署一个非常简单的 REST 应用程序。该应用程序正在向 Eureka 服务器注册，如果我将其部署为 JAR 文件，则该应用程序可以正常工作。
现在的问题是，当我使用
mvn clean -Pnative native:compile

我的 pom.xml 包含这个：
<plugin>
<groupId>org.graalvm.buildtools</groupId>
<artifactId>native-maven-plugin</artifactId>
</plugin>
我正在使用这个版本的Java：
java version "17.0.8" 2023-07-18 LTS
Java(TM) SE Runtime Environment Oracle GraalVM 17.0.8+9.1 (build 17.0.8+9-LTS-jvmci-23.0-b14)
Java HotSpot(TM) 64-Bit Server VM Oracle GraalVM 17.0.8+9.1 (build 17.0.8+9-LTS-jvmci-23.0-b14, mixed mode, sharing)
这是应用程序：
package com.example.creditscore;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
@EnableDiscoveryClient
@SpringBootApplication
public class CreditscoreApplication {
public static void main(String[] args) {
SpringApplication.run(CreditscoreApplication.class, args);
}
}
package com.example.creditscore.controller;
import org.springframework.web.bind.annotation.*;
import lombok.extern.slf4j.Slf4j;
import java.security.SecureRandom;
import java.util.HashMap;
import java.util.Map;
@RestController
@RequestMapping("/api/v1")
@Slf4j
public class CreditScoreController {
@GetMapping("/creditscore")
public Map<String, String> getCreditScore() {
log.info("CREDITSCORE: getCreditScore");
int max = 900;
int min = 500;
SecureRandom secureRandom = new SecureRandom();
HashMap<String, String> map = new HashMap<>();
map.put("Credit Score", String.valueOf(secureRandom.nextInt(max - min) + min));
map.put("Date", String.valueOf(java.time.LocalDate.now()));
return map;
}
}
application.yaml 如下所示：
spring:
application:
name: creditscore
zipkin:
base-url: ${zipkin.base-url}
eureka:
instance:
hostname: ${spring.application.name}
preferIpAddress: true

如果我进行 kubectl 描述部署，我会得到以下信息：

关于我做错的事情有什么好主意吗？
尝试指定运行状况端点属性以仅包含您需要的运行状况指标。您可以将以下配置添加到您的 application.yaml 中：
management:
...
health:
diskspace:
enabled: true
db:
enabled: true
...
在我的例子中似乎解决问题的是添加
spring.cloud.refresh.enabled=false
