Quarkus使用InMemoryConfigSource后本地运行仍部署Docker问题求助

问题 #

为了隐藏application.properties中的数据库凭证，我实现了InMemoryConfigSource类并移除了配置文件里的数据源凭证信息。但现在不管怎么选本地配置，运行应用时都会在Docker里创建新数据库并在Docker环境运行。我需要实现本地运行应用并连接远程数据库，而且因为要以编程方式隐藏和修改quarkus.datasource.jdbc.url，所以credentials-provider方案不适用。

我的InMemoryConfigSource类 #

import io.quarkus.runtime.annotations.StaticInitSafe;
import org.eclipse.microprofile.config.spi.ConfigSource;
import java.util.Map;
import java.util.HashMap;
import java.util.Set;

@StaticInitSafe
public class InMemoryConfigSource implements ConfigSource {
    private static final Map<String, String> configuration = new HashMap<>();

    static {
        configuration.put("quarkus.datasource.db-kind", "postgresql");
        configuration.put("quarkus.datasource.jdbc.url" ,"url");
        configuration.put("quarkus.datasource.username" , "foo");
        configuration.put("quarkus.datasource.password" , "bar");
        configuration.put("quarkus.hibernate-orm.database.generation", "update");
    }

    @Override
    public int getOrdinal() {
        return 400;
    }

    @Override
    public Set<String> getPropertyNames() {
        return configuration.keySet();
    }

    @Override
    public String getValue(final String propertyName) {
        return configuration.get(propertyName);
    }

    @Override
    public String getName() {
        return InMemoryConfigSource.class.getSimpleName();
    }
}

解决方案 #

1. 注册自定义配置源 #

Quarkus无法自动识别你的InMemoryConfigSource，需要手动注册：
在src/main/resources/META-INF/services目录下创建文件org.eclipse.microprofile.config.spi.ConfigSource，内容为你的类全限定名（替换成实际包路径）：

com.xxxx.InMemoryConfigSource

2. 关闭Dev Services自动创建Docker数据库 #

Quarkus开发模式下默认会启动Dev Services自动创建Docker数据库，需要在你的配置源中添加配置强制关闭：

configuration.put("quarkus.datasource.devservices.enabled", "false");

3. 调整配置源优先级（可选） #

当前getOrdinal()返回400，和系统属性优先级相同，系统属性会覆盖你的配置。如果需要让自定义配置源优先级更高，修改返回值为450：

@Override
public int getOrdinal() {
    return 450;
}

4. 验证远程数据库连接信息 #

确保quarkus.datasource.jdbc.url是正确的远程PostgreSQL格式：

jdbc:postgresql://<远程主机IP>:<端口>/<数据库名>

同时确认远程数据库允许本地IP访问，用户名和密码正确。

5. 本地启动时强制指定配置源（可选） #

如果仍有问题，用Maven命令启动时添加参数：

./mvnw quarkus:dev -Dquarkus.config.source.in-memory.enabled=true
