避免繁复的get/set操作 摘自：夏昕 Hibernate_DEV_GUIDE 为避免繁复的get/set操作，你可以通过Apache Jakarta Commons Beanutils 组件提供的属性批量复制功能（http://jakarta.apache.org/commons/beanutils/）.下面的例子中，我们把user对象的所有属性复制到anotherUser对象中：
TUser user = new TUser();
TUser anotherUser = new TUser();
user.setName("Emma");
user.setUserType(1);
try {
BeanUtils.copyProperties(anotherUser,user);
System.out.println("UserName => "
+anotherUser.getName()
);
System.out.println("UserType => "
+ anotherUser.getUserType()
);
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
}
TUser user = new TUser();
TUser anotherUser = new TUser();
user.setName("Emma");
user.setUserType(1);
try {
BeanUtils.copyProperties(anotherUser,user);
System.out.println("UserName => "
+anotherUser.getName()
);
System.out.println("UserType => "
+ anotherUser.getUserType()
);
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
}
TUser user = new TUser();
TUser anotherUser = new TUser();
user.setName("Emma");
user.setUserType(1);
try {
BeanUtils.copyProperties(anotherUser,user);
System.out.println("UserName => "
+anotherUser.getName()
);
System.out.println("UserType => "
+ anotherUser.getUserType()
);
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
}
