判断一个map是否包含另一个map

for (Map.Entry entry : finpmap.entrySet()) {

						String finpmapKey = (String) entry.getKey();

						String finpmapValue = (String) entry.getValue();

						String finpmapKeyVal = finpmapKey + ":" + finpmapValue;

						boolean keyExist = salemap.containsKey(finpmapKeyVal);

						boolean valExist = salemap.containsValue(finpmapKeyVal);

						if (keyExist == false) {

							return ;
						}
					}
