对已有程序进行了aspectj的整合

自从前几天发布了一个版本后，我就开始对ostocy-jshop做一些优化，让代码的耦合性减少。我就找到了aspectj在看了一些资料以后对其进行了整合。

简单的说下步骤和整合的功能代码吧

 

1,在eclipse中安装aspectj插件，找到help-=install new software 输入http://download.eclipse.org/tools/ajdt/36/update 这个地址。选择第一个安装即可。

 

 

 

2，把项目转换到aspectj模式下

 

右键项目--configuratie--有一个covert to aspectj 

 

3，看下spring的配置文件吧

最主要的就是这几行和注意载入的头 

 

<aop:aspectj-autoproxy>
		
	</aop:aspectj-autoproxy>
	
	<context:component-scan base-package="com.jshop">
	</context:component-scan>
	<context:annotation-config />

 这里其实就是在设置自动检索所有被标注了@AspectJ的类了

 

4，看下aspectj的类吧

 

 

@Aspect
public class CreateStaticHtmlAspect {
	private Map<String, Object> map = new HashMap<String, Object>();
	

	public Map<String, Object> getMap() {
		return map;
	}

	public void setMap(Map<String, Object> map) {
		this.map = map;
	}

	/**
	 * 在商品增加/修改时更新静态页
	 * @throws TemplateException 
	 * @throws IOException 
	 */
	@After("execution(String com.jshop.action.GoodsTNAction.updateGoods())||execution(String com.jshop.action.GoodsTNAction.addGoods())")
	public void aftergoodsIUCreatestatichtml(JoinPoint joinPoint) throws IOException, TemplateException{
		GoodsTNAction gtn=(GoodsTNAction) joinPoint.getThis();
		if(gtn.getBean()!=null){
			String basepath=gtn.getDataCollectionTAction().getBasePath();
			String theme=gtn.getDataCollectionTAction().getDefaultTheme();
			String htmlpath="html/"+theme+"/shop/"+gtn.getBean().getGoodsid()+".html";
			gtn.getBean().setHtmlPath(htmlpath);
			//获取默认项目路径
			map.put(FreeMarkervariable.BASEPATH,basepath);
			//获取默认主题
			map.put(FreeMarkervariable.DEFAULTTHEMESIGN, theme);
			//获取商城基本信息
			map.put(FreeMarkervariable.JSHOPBASICINFO, gtn.getDataCollectionTAction().findJshopbasicInfo());
			//获取导航
			map.put(FreeMarkervariable.SITENAVIGATIONLIST, gtn.getDataCollectionTAction().findSiteNavigation());
			//获取页脚文章一级分类
			map.put(FreeMarkervariable.FOOTCATEGORY, gtn.getDataCollectionTAction().findFooterCateogyrT());
			//获取页脚文章一级分类下得文章
			map.put(FreeMarkervariable.FOOTERATRICLE, gtn.getDataCollectionTAction().findFooterArticle());
			//获取商品详细
			map.put(FreeMarkervariable.GOODSDETAIL, gtn.getBean());
			//这里获取商品参数和商品类型表中的对比并显示
			map.put(FreeMarkervariable.GOODSPARAMETERS,gtn.processGoodsparameters(gtn.getBean()));;//这是处理过后的商品参数,用在freemarker模板
			String htmlPath = gtn.getCreateHtml().createGoodsT(BaseTools.getApplicationthemesig() + "_" + ContentTag.TEMPLATENAMEFORGOODSDETAIL, gtn.getBean().getGoodsid(), map);
			if (Validate.StrNotNull(htmlPath)) {
				gtn.getGoodsTService().updateHtmlPath(gtn.getBean().getGoodsid(), htmlPath);
			}
		}
		
	}
}

 

至于aspectj的语法不多说了，功能很多，讲起来会更多。这里主要就是如何获取切入点的上下文。也就是我如何获取被我after的方法所在类的所有变量和方法和依赖注入的对象。只要JoinPoint作为参数就行了。然后你想拿什么就拿什么。可以断点自己看看。

 

 

结束，就这样吧。以上代码均来自我写的开源商城程序，希望大家可以来一起学习一起进步。我也是个菜鸟，希望一起进步啊。
