Spring 带数据库后端的云配置服务器

Question

我正在尝试创建一个 Spring 云配置服务器，它从 database 而不是默认的 git-repo 获取配置。

每次我尝试运行我的配置服务器应用程序时，我都会收到此错误：

Execution failed for task ':config-server:applications:config-server:bootRun'.
> Process 'command 'C:\Program Files\choco\openjdk-jdk-11\latest\bin\java.exe'' finished with non-zero exit value 1

此消息来自服务器本身（重新格式化以便更好地阅读）：

[ERROR agnostics.LoggingFailureAnalysisReporter : 
APPLICATION FAILED TO START
Description: Invalid config server configuration.
Action: If you are using the git profile, you need to set a Git URI in your configuration.  If you are using a native profile and have spring.cloud.config.server.bootstrap=true, you need to use a composite configuration.
[main||||||| - |]]

我的application.yaml里面有这个部分：

spring:
  application:
    name: my-services-api
  datasource:
    url: jdbc:h2:mem:testdb
    driver-class-name: org.h2.Driver
    platform: h2
    hikari:
      connection-timeout: 5000
      maximum-pool-size: 10
  cloud:
    config:
      server:
        jdbc:
          sql: SELECT KEY, VALUE from MY_PROPERTIES where APPLICATION=? and PROFILE=? and LABEL=?
          order: 1
  h2:
    console:
      enabled: true

如您所见，没有 spring.cloud.config.server.bootstrap=true 所以我不知道它要我做什么。
我也不想使用 git 配置文件，所以 Action 对我一点帮助都没有。

有人知道我该如何解决这个问题吗？谢谢

更新： 我添加了 spring.cloud.config.server.git.uri 并将 jdbc 的顺序更改为 1，将 git 的顺序更改为 2.
在那之后它有点工作但我仍然有问题，它不会从数据库中读取配置

我正在尝试调试你的问题，我有以下设置并且可以成功启动服务器以及查询 API。

我的 maven 构建配置文件

</project>

主要class

@EnableConfigServer
@SpringBootApplication
public class ConfigserverApplication {

    public static void main(String[] args) {
        SpringApplication.run(ConfigserverApplication.class, args);
    }

}

#bootstrap.yml
spring:
  application:
    name: my-services-api
  datasource:
    url: jdbc:h2:mem:testdb
    driver-class-name: org.h2.Driver
    platform: h2
    hikari:
      connection-timeout: 5000
      maximum-pool-size: 10
  profiles:
    active: jdbc
  cloud:
    config:
      server:
        jdbc:
          sql: "SELECT properties.key, properties.value from properties where application=? and profile=? and label=?"
          order: 1
  h2:
    console:
      enabled: true

我也将 schema.sql 和 data.sql 放入 class 路径（maven 项目的资源文件夹），以便它们将数据自动填充到嵌入式 h2 数据库中。

#schema.sql

DROP TABLE IF EXISTS PROPERTIES;
    
CREATE TABLE PROPERTIES (
  id INT AUTO_INCREMENT  PRIMARY KEY,
  APPLICATION VARCHAR(25) NOT NULL,
  PROFILE VARCHAR(25) NOT NULL,
  LABEL VARCHAR(25) DEFAULT NULL,
  KEY VARCHAR(25) NOT NULL,
  VALUE VARCHAR(200) NOT NULL   
);
    
#data.sql
    
INSERT INTO PROPERTIES( APPLICATION, PROFILE, LABEL, KEY, VALUE) 
values('myapp', 'MYCLIENT', '1.1', 'prop1', 'val11');
INSERT INTO PROPERTIES( APPLICATION, PROFILE, LABEL, KEY, VALUE) 
values('myapp', 'MYCLIENT', '1.1', 'prop2', 'val12');
INSERT INTO PROPERTIES( APPLICATION, PROFILE, LABEL, KEY, VALUE) 
values('myapp', 'MYCLIENT', '1.1', 'prop3', 'val13');
INSERT INTO PROPERTIES( APPLICATION, PROFILE, LABEL, KEY, VALUE) 
values('myapp', 'MYCLIENT', '1.0', 'prop1', 'val21');
INSERT INTO PROPERTIES( APPLICATION, PROFILE, LABEL, KEY, VALUE) 
values('myapp', 'MYCLIENT', '1.0', 'prop2', 'val22');
INSERT INTO PROPERTIES( APPLICATION, PROFILE, LABEL, KEY, VALUE) 
values('myapp', 'MYCLIENT', '1.0', 'prop3', 'val23');

我可以成功启动和查询配置服务器

您的 application.yaml 文件丢失属性： spring: 简介：活动：jdbc

我已经为具有 JDBC 后端的云配置服务器实现了类似的项目，下面是参考： https://github.com/Santhoshinftech/cloud-config-custom-svc
