Examples with ConfigFileService com.tencent.polaris.configuration.api.core.ConfigFileService used on opensource projects

Example 1 with ConfigFileService

use of com.tencent.polaris.configuration.api.core.ConfigFileService in project polaris-java by polarismesh.

the class ConfigPropertiesFileExample method main.

public static void main(String[] args) throws IOException {
    String namespace = "dev";
    String fileGroup = "myGroup";
    String fileName = "application.properties";
    // 创建配置中心服务类，一般情况下只需要单例对象
    ConfigFileService configFileService = ConfigFileServiceFactory.createConfigFileService();
    // 获取 properties 格式配置文件对象
    ConfigKVFile configFile = configFileService.getConfigPropertiesFile(namespace, fileGroup, fileName);
    // 获取配置文件完整内容
    Utils.print(configFile.getContent());
    // 获取特定的 key 的值
    Utils.print(configFile.getProperty("key1", "some default value"));
    // 更多基础类型方法
    // getIntProperty、getFloatProperty ...
    // 更多高级数据结构方法
    // getEnumProperty、getArrayProperty、getJsonProperty
    // 获取 Properties
    // asProperties
    // 监听变更事件，kv类型的变更事件可以细化到 key 粒度的变更
    configFile.addChangeListener(new ConfigKVFileChangeListener() {

        @Override
        public void onChange(ConfigKVFileChangeEvent event) {
