ApplicationContext应用上下文体系如下：

AbstractRefreshableConfigApplicationContext是一个抽象类，其中并没有多少具体的操作，具体的操作都在其子类和父类中。

源码如下：

/**
     * 也没有太多具体的操作，主要的操作都在子类和父类中
     */
    public abstract class AbstractRefreshableConfigApplicationContext extends AbstractRefreshableApplicationContext
    		implements BeanNameAware, InitializingBean {
    
    	private String[] configLocations;
    
    	private boolean setIdCalled = false;
    
    
    	public AbstractRefreshableConfigApplicationContext() {
    	}
    
    
    	public AbstractRefreshableConfigApplicationContext(ApplicationContext parent) {
    		super(parent);
    	}
    
    
    
    	public void setConfigLocation(String location) {
    		setConfigLocations(StringUtils.tokenizeToStringArray(location, CONFIG_LOCATION_DELIMITERS));
    	}
    
    
    	public void setConfigLocations(String... locations) {
    		if (locations != null) {
    			Assert.noNullElements(locations, "Config locations must not be null");
    			this.configLocations = new String[locations.length];
    			for (int i = 0; i < locations.length; i++) {
    				this.configLocations[i] = resolvePath(locations[i]).trim();
    			}
    		}
    		else {
    			this.configLocations = null;
    		}
    	}
    
    
    	protected String[] getConfigLocations() {
    		return (this.configLocations != null ? this.configLocations : getDefaultConfigLocations());
    	}
    
    
    	protected String[] getDefaultConfigLocations() {
    		return null;
    	}
    
    
    	protected String resolvePath(String path) {
    		return getEnvironment().resolveRequiredPlaceholders(path);
    	}
    
    
    	@Override
    	public void setId(String id) {
    		super.setId(id);
    		this.setIdCalled = true;
    	}
    
    
    	@Override

    		if (!this.setIdCalled) {
    			super.setId(name);
    			setDisplayName("ApplicationContext '" + name + "'");
    		}
    	}
    
    	@Override
    	public void afterPropertiesSet() {
    		if (!isActive()) {
    			refresh();
    		}
    	}
    
    }
