Question

我正在尝试在GWT 2.7中使用validator.validateValue（）方法，并且它似乎对集合上的@Size注释不起作用。

我正在尝试验证这个POJO ......：

public class Person {
  @Size(min = 3, message = "Name not long enough")
  private String mName;

  @Size(min = 3, message = "Not enough course subscriptions")
  private List<String> mCourses;

  public String getName() {
    return mName;
  }

  public void setName(String pName) {
    mName = pName;
  }    

  public void setCourses(final List<String> pCourses) {
    mCourses = pCourses;
  }

  public List<String> getCourses() {
    return mCourses;
  }
}

...使用此验证方法：

void validate() {

    final Validator validator = Validation.buildDefaultValidatorFactory().getValidator();

    final Person person = new Person();
    person.setName("Ed");//too short
    person.setCourses(Arrays.asList("Math", "Bio"));//not enough

    System.out.println("with validate object");

    final Set<ConstraintViolation<Person>> violations = validator.validate(person);

    for (ConstraintViolation<Person> violation : violations) {
      System.out.println(violation.getMessage());
    }

    System.out.println("with validateValue");

    final Set<ConstraintViolation<Person>> violationsName = validator.validateValue(Person.class, "mName", person.getName());

    for (ConstraintViolation<Person> violation : violationsName) {
      System.out.println(violation.getMessage());
    }

    final Set<ConstraintViolation<Person>> violationsCourses = validator.validateValue(Person.class, "mCourses", person.getCourses());

    for (ConstraintViolation<Person> violation : violationsCourses) {
      System.out.println(violation.getMessage());
    }
}

在普通Java中运行此代码时我正确获取：

with validate object
Name not long enough
Not enough course subscriptions

with validateValue
Name not long enough
Not enough course subscriptions

但是当在GWT中运行此代码时，我错误地获取：

with validate object
Name not long enough
Not enough course subscriptions

with validateValue
Name not long enough

似乎GWT 2.7中的Validator.validateValue（）方法没有正确验证应用于Collection的@Size注释。

有什么想法吗？提前谢谢！

我对String属性有同样的问题。当我重新启动SDM时，它运行正常。

严重的是，每次验证更改后都必须重新启动SDM。

GWT与bean验证不一致
