annotations

问题 In Struts 2, I am trying to skip validation on method base on XML configuration. As per my application I can not use annotation. So I cannot use @SkipValidation annotation. Is there any alternative for this? I have one action class which has five methods create , update , delete , search , and view . I want to validate only two methods create and update . 回答1: You should configure in the struts.xml package with interceptors <interceptors> <interceptor-stack name="validateWorkflowStack">

问题 I have created annotations that show up perfectly on my map but I am not sure how to implement the leftCalloutAccessoryView to show images. MapViewAnnotation.h #import <Foundation/Foundation.h> #import <MapKit/MapKit.h> @interface MapViewAnnotation : NSObject <MKAnnotation> @property (nonatomic, assign) CLLocationCoordinate2D coordinate; @property (nonatomic, copy) NSString *title; @property (nonatomic, copy) NSString *subtitle; @end MapViewAnnotation.m #import "MapViewAnnotation.h"

问题 I have an old appfuse project, running Spring 2.0, and Java 1.6, and I'm trying to get Transaction annotation support (and other annotations) running. But, when I add this to our class: @Transactional public class ... { } We get an ant compile issue, like: [javac] symbol: class Transactional [javac] @Transactional [javac] ^ How do I tell ant which Spring transactions it should be using? 回答1: This looks like a simple import problem to me. Have you imported the class org.springframework

问题 I have read a lot of @Transactional annotation, I saw stackoverflow answers but it does not help me. So I am creating my question. My case is to save user with unique email. In DB I have user with email xxx@xxx.com, and I am saving user with the same email address. For saving I have to use entityManager.merge() because of this post thymeleaf binding collections it is not important. First example: @Controller public class EmployeeController extends AbstractCrudController { // rest of code (...

问题 I'm using TestNG and Selenium in Eclipse, in Java. I have a method test that calls the other methods as support for the actions it needs to perform. I have them marked as part of the test using @Test . @BeforeTest public void beforeTest() { driver.manage().window().maximize(); } @Test public static void checkValidity(String[] array, WebDriver driver){ String partialURL = ""; int brokenLinks = 0; for (int x=1; x<array.length; x+=2){ partialURL = anonUserSitemapExperience.getPartialURL(driver,

问题 I'm using doctrine annotations in my entities definition to define each variable behavior, i.e.: @ORM\Column(type="string", length=50, nullable=false) If I submit the form leaving the field empty, it pass the validation, but (of corse) I receive an error about the INSERT statement, because he cannot insert NULL value. How this could be possible? 回答1: This is because Symfony does not automatically validate your form input based on Doctrine annotations. Symfony2 ships with a Validator component

问题 I want to map a Map<Long, List<ItemAttribute>> inside an @Entity class where ItemAttribute itself is an @Entity defined separately. Here is the code that I am using for mapping: @Entity @Table(name = "ITEM_ATTRIBUTE_GROUP") public class ItemAttributeGroup implements Cloneable, Serializable { @ElementCollection @MapKeyColumn(name="groupId") @JoinTable(name = "ATTRIBUTES_IN_GROUP", joinColumns = @JoinColumn(name = "groupId"), inverseJoinColumns = @JoinColumn(name = "ID")) private Map<Long, List

问题 Hey everyone, I am working on parsing the PDF content stream to be able to read and handle annotation operators and also to add these. Can anyone shed some light on how to go about doing this, without using a prebuilt library? I understand it is a daunting exercise, but any pointers would be appreciated. Note: I've read a fair amount of the PDF Reference from Adobe, and mostly understand the concept of the file being an object tree, yet I don't understand how to go about figuring out if an

问题 I'm drawing some ink annotations on a PDF file using PDFKit. But I can't change the width of the lines. I thought that doing: let path = UIBezierPath() path.lineWidth = 20 // important line path.move(to: originPoint) path.addLine(...) annotation.add(path) would be enough since modifying the lineWidth of a Bezier path works when drawing in Core Graphics. But here, it does not change anything, so how to change the line width of an annotation ? 回答1: Use border property of PDFAnnotation to change
