在不重启应用程序服务器或在运行时重新初始化 spring 个 beans

Re-Initialize spring beans without app server restart or at runtime

有没有办法动态地重新初始化 spring bean?

在应用程序启动时,我在 web.xml 中通过 ContextLoaderListener 初始化 spring 个 bean。

我的用例是,在运行时可能会出现新的 属性 文件被加载到内存中的情况(通过 Apache commons 配置),我想重新初始化这些 bean,这样它就可以在不影响的情况下生效不得不重新启动。

感谢任何对此的指点。

能够通过 class 实现 ApplicationContextAware

来解决它
public class ReloadConfig implements ApplicationContextAware{

private static Logger log = Logger.getLogger(ReloadConfig.class);


private Config config;

@Autowired
ApplicationContext applicationContext;

private ReloadConfig() {
    // Exists only to defeat instantiation.
    config = Config.getInstance();
}

public void reloadIfNotLoaded() throws ConfigurationException{

    CompositeConfiguration configuration = new CompositeConfiguration();

    if(config.getHealthFile() == null){

        log.info("Reloading Adding default properties found in config.properties");
        configuration.addConfiguration(new PropertiesConfiguration("config.properties"));


        ConfigurableApplicationContext configurableApplicationContext = (ConfigurableApplicationContext)getApplicationContext();
        configurableApplicationContext.refresh();
        setApplicationContext(configurableApplicationContext);
    }



}

public void setApplicationContext(ApplicationContext context) throws BeansException {
    applicationContext = context;
}

public ApplicationContext getApplicationContext() {
    return applicationContext;
}
