@Target
(ElementType.FIELD)
@Retention
(RetentionPolicy.RUNTIME)
public
@interface
IgnoreProperty {
}
然后实体类中:
public
class
TarResearch
implements
Serializable{
@IgnoreProperty
private
static
final
long
serialVersionUID = 1L;
@IgnoreProperty
private
Integer researchId;
@IgnoreProperty
private
TarUser userId;
private
String version;
private
String grade;
....
}
然后action类中
// 验证数据完整性
Class<TarResearch > userClass = TarResearch .
class
;
Field[] field = userClass.getDeclaredFields();
for
(
int
i =
0
; i < field.length; i++) {
if
(field[i].getAnnotation(IgnoreProperty.
class
) !=
null
) {
continue
;
}
String fie = field[i].getName().substring(
0
,
1
).toUpperCase()
+ field[i].getName().substring(
1
);
Method method = userClass.getMethod(
"get"
+ fie);
Object obj = method.invoke(u);
if
(obj ==
null
) {
sendResponseMsg(response,
"数据错误"
);
return
null
;
}
}
