Servicemix找不到javax.validation包

Question

我用的是servicemix-4.4.1

在我的pom.xml中，我定义了一个依赖项：

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>4.3.1.Final</version>
    <scope>provided</scope>
</dependency>

如您所见，我将作用域设置为provided，因为servicemix ( osgi容器)将为我们提供jar。

在我的features.xml文件中，我添加了：

<feature name="myapp-libs" version="${version}">
    ....
    <bundle>mvn:org.hibernate/hibernate-validator/4.3.1.Final/jar</bundle>

现在，当我尝试将myapp-libs加载到servicemix中时，我得到了以下结果：

karaf@root> features:install myapp-libs
Error executing command: Could not start bundle mvn:org.hibernate/hibernate-validator/4.3.1.Final/jar in feature(s) 
myapp-libs-1.24-SNAPSHOT: Unresolved constraint in bundle org.hibernate.validator [973]: 
Unable to resolve 973.0: missing requirement [973.0] package; (&(package=javax.validation)(version>=1.0.0)(!(version>=2.0.0)))

Answer 1

我在我的features.xml中定义了javax.validation：

<bundle>mvn:javax.validation/validation-api/1.1.0.Final/jar</bundle> 

但是之后它就再也找不到hibernate-validator jar了：

Add a provider like Hibernate Validator (RI) to your classpath.
javax.validation.ValidationException: Unable to create a Configuration, because no Bean Validation provider could be found. Add a provider like Hibernate Validator (RI) to your classpath.
at javax.validation.Validation$GenericBootstrapImpl.configure(Validation.java:271)
at javax.validation.Validation.buildDefaultValidatorFactory(Validation.java:110)

这很奇怪，因为在日志中我可以看到hibernate-validator正在加载。

Answer 2

hibernate验证器需要1.0.0或更高版本的javax.validation包，但不需要2.0.0版。这意味着您需要在特性xml中包含另一个包，或者确保servicemix设置为支持JSR303 / javax.validation。
