如何用gwt-2.4.0安装gwt-validation [英] How to install gwt-validation with gwt-2.4.0

问题描述

我想在Gwt 2.4.0上使用 Gwt-Validation 。

我在我的gwt.xml文件中：

 < inherits name =javax.validation.Validation/> 
<继承了name =com.google.gwt.validation.Validation/> 
<继承了name ='com.em.validation.Validation'/> 
  

像在文档中一样，我有以下代码：

  import javax.validation.Validator; 
 import javax.validation.ValidatorFactory; 
 ... 
 
 ValidatorFactory factory = 
 Validation.byDefaultProvider（）。configure（）。buildValidatorFactory（）; 
 
 Validator validator = factory.getValidator（）; 
  

问题是我有以下错误：

延迟绑定结果类型'javax.validation.ValidationFactory'不应该是抽象的。

// ...美丽的堆栈跟踪主要是：

'javax.validation.ValidatorFactory'的延迟绑定失败（
是否忘记继承一个必需的模块？）

我的pom.xml包含：

 < dependency> 
< groupId> com.googlecode.gwt-validation< / groupId> 
< artifactId> gwt-validation< / artifactId> 
< version> 2.0< / version> 
< /依赖关系> 
< dependency> 
< groupId> javax.validation< / groupId> 
< artifactId> validation-api< / artifactId> 
< version> 1.0.0.GA< / version> 
< scope>提供< / scope> 
< /依赖关系> 
< dependency> 
< groupId> javax.validation< / groupId> 
< artifactId> validation-api< / artifactId> 
< version> 1.0.0.GA< / version> 
< classifier> sources< / classifier> 
< scope>提供< / scope> 
< /依赖关系> 
  

我该怎么办？
Thanks。

解决方案

问题出在java导入。

在以下代码中：

  ValidatorFactory factory = 
 Validation.byDefaultProvider（）。configure（）。 buildValidatorFactory（）; 
 Validator validator = factory.getValidator（）; 
  

我汇入：

com.google.gwt.validation.client 而不是 javax.validation

< Java编译时没有错误！只需在gwt编译时的上述错误（或托管模式的运行时）。

I would like to use Gwt-Validation with Gwt 2.4.0.

I have in my gwt.xml file :

  <inherits name="javax.validation.Validation" />
  <inherits name="com.google.gwt.validation.Validation" />
  <inherits name='com.em.validation.Validation' />

Like in the documentation, I have the following code :

import javax.validation.Validator;
import javax.validation.ValidatorFactory;
...

ValidatorFactory factory =
    Validation.byDefaultProvider().configure().buildValidatorFactory();

Validator validator = factory.getValidator();

The problem is that I have the following error :

Deferred binding result type 'javax.validation.ValidationFactory' should not be abstract.

//... beautiful stacktrace with mainly :

Deferred binding failed for 'javax.validation.ValidatorFactory' (did you forget to inherit a required module?)

My pom.xml contains :

<dependency>
  <groupId>com.googlecode.gwt-validation</groupId>
  <artifactId>gwt-validation</artifactId>
  <version>2.0</version>
</dependency>
<dependency>
  <groupId>javax.validation</groupId>
  <artifactId>validation-api</artifactId>
  <version>1.0.0.GA</version>
  <scope>provided</scope>
</dependency>
<dependency>
  <groupId>javax.validation</groupId>
  <artifactId>validation-api</artifactId>
  <version>1.0.0.GA</version>
  <classifier>sources</classifier>
  <scope>provided</scope>
</dependency>

What can I do ? Thanks.

解决方案

The problem was in the java imports.

In the following code :

ValidatorFactory factory =
    Validation.byDefaultProvider().configure().buildValidatorFactory();
Validator validator = factory.getValidator();

I imported :

com.google.gwt.validation.client instead of javax.validation

No error at java compile time ! Just the errors above at gwt compile time (or runtime with the hosted mode).
