Spring Boot 集成Spring Cloud Config：实现集中化配置管理

import org.springframework.cloud.config.client.ConfigClientProperties;
import org.springframework.cloud.config.client.ConfigServicePropertySourceLocator;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.env.Environment;
import org.springframework.core.env.PropertySource;
 
@Configuration
public class ConfigServiceConfig {
 
    private final ConfigClientProperties properties;
    private final ConfigServicePropertySourceLocator locator;
    private final Environment environment;
 
    public ConfigServiceConfig(ConfigClientProperties properties, ConfigServicePropertySourceLocator locator, Environment environment) {
        this.properties = properties;
        this.locator = locator;
        this.environment = environment;
    }
 
    public void loadConfig() {
        // 设置Config服务的基础属性
        properties.setUri("http://config-server-uri");
        properties.setUsername("config-server-username");
        properties.setPassword("config-server-password");
 
        // 从Config服务加载配置
        locator.locate(environment).forEach(propertySource -> {
            ((MutablePropertySources) environment.getPropertySources()).addFirst(propertySource);
        });
    }
}

这段代码演示了如何在Spring Boot应用中集成Spring Cloud Config。首先，我们创建了一个配置类ConfigServiceConfig，在其构造函数中注入了必要的配置客户端属性、Config服务的定位器以及Spring的环境对象。然后，我们定义了一个loadConfig方法来设置Config服务的连接属性，并从Config服务加载配置。这里使用了MutablePropertySources将加载的配置添加到应用的环境中。
