对List<Map<String, Object>>的数据结构的添加和删除实例添加//初始化List<Map<String, Object>> products = new ArrayList<Map<String,Object>>();//也可以这样初始化List<Map<String, Object>> products = null//初始Map<String,Object>Map<String,Object> product01 = null;product01.put("Parameter01", "Key1"); Map<String,Object> product02 = null;String parameter02 = "Parameter02";String key2 = "theContentOfKey2";product02.put(parameter02, key2);//一个一个添加products.add(product01);products.add(product02);//从Service中获取List<Map<String, Object>> productsAddition = productService.getProduct(); //遍历添加for(Map<String, Object> product: productsAddition){products.add(product);}
删除--使用迭代删除//初始化List<Map<String, Object>> products = null;//获取List元素products = productService.getProduct(); //使用迭代删除Iterator<Map<String, Object>> productsIterator = products.iterator();while (productsIterator.hasNext()) {//删除特定元素Map<String, Object> product = productsIterator.next();if("product01".equals(product.get("productName"))){productsIterator.remove();}if("product02".equals(product.get("productName"))){productsIterator.remove();}}
