Commons BeanUtils的基本用法

langhua9527

//1.Commons beanutils要用到的三个包，一个主要包commons-beanutils-1.8.0.jar和两个依赖包commons-logging-1.1.1.jar和commons-logging-api-1.1.1.jarpublic class BeanUtilsExample {public static void main(String[] args) throws IllegalAccessException, InvocationTargetException, NoSuchMethodException {Profile profile = new Profile();Map<String,String> map = new HashMap<String,String>();map.put("home", "123");map.put("tel", "12574");profile.setPhone(map);profile.setBrithDate(new Date());profile.setEmail("langhua@qq.com");Address[] address = {new Address("pzh","xj"),new Address("km","rmdl")};profile.setAddress(address);User user = new User();user.setId(100);user.setUsername("username");user.setPassword("password");user.setProfile(profile);//一般类型prt(BeanUtils.getProperty(user, "id"));//引用类型的一般类型prt(BeanUtils.getProperty(user, "profile.brithDate"));//Map类型prt(BeanUtils.getProperty(user, "profile.phone(home)"));//数组和List，Set类型prt(BeanUtils.getProperty(user, "profile.address[0].city"));User user2 = new User();//复制Bean，但如果Bean里面引用类型的不能复制BeanUtils.copyProperties(user2, user);}public static void prt(Object object){System.out.println(object);}}
