ClassPathXmlApplicationContext

提示：ResourceLoader表示一种加载资源的方式，是策略模式的实现。

//构造器(部分)
public ClassPathXmlApplicationContext(String[] configLocations, boolean refresh, ApplicationContext parent) throws BeansException {
    super(parent);
    this.setConfigLocations(configLocations);
    if (refresh) {
        this.refresh();
    }
}

父类构造器(AbstractApplicationContext)

public AbstractApplicationContext() {
    this.logger = LogFactory.getLog(this.getClass());
    this.id = ObjectUtils.identityToString(this);
    this.displayName = ObjectUtils.identityToString(this);
    this.beanFactoryPostProcessors = new ArrayList();
    this.active = new AtomicBoolean();
    this.closed = new AtomicBoolean();
    this.startupShutdownMonitor = new Object();
    this.applicationListeners = new LinkedHashSet();
    this.resourcePatternResolver = this.getResourcePatternResolver();
}

public AbstractApplicationContext(ApplicationContext parent) {
    this();
    this.setParent(parent);
}

protected ResourcePatternResolver getResourcePatternResolver() {
    return new PathMatchingResourcePatternResolver(this);
}
