基于spring的PropertySource类实现配置的动态替换

public class ConfigPropertySource extends PropertySource<Properties> implements PriorityOrdered, BeanFactoryPostProcessor, EnvironmentAware{

public void init() {
    this.loadConfig();
    this.env.getPropertySources().addFirst(this);
}

private Properties parseConfig(String config) {
    Properties properties = new Properties();
    if(StringUtils.isNotEmpty(config)) {
        try {
            properties.load(new StringReader(config));
        } catch (Exception var4) {
            throw new IllegalArgumentException("detail center parse config error, config:" + config, var4);
        }
    }

    return properties;
}

public Object getProperty(String name) {
    return this.source.get(name);
}

}
