Javax验证

Question

我正在尝试在Spring中使用Javax验证。当我运行我的应用程序时，我收到一条奇怪的错误消息

javax.servlet.ServletException: Servlet.init() for servlet dispatcher threw exception

我的类路径中有hibernate-validator-4.0.2 GA.jar，它似乎有缺失的类。我也用jdk 6，出什么问题了？我用谷歌搜索了一下，但没有找到答案。

Answer 1

堆栈跟踪显示Hibernate Validator和javax.validation API JARs都在您的类路径上，所以问题出在别处。

ConfigurationImpl的源代码表明它依赖于SLF4J。

我猜那不是你的类路径？

Answer 2

我将以下内容添加到Maven项目的POM中解决了这个问题：

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

您还可以检查official reference。

Answer 3

Jar- hibernate-validator4.3.1 final.jar文件- HibernetValidator.java第41行-

 public Configuration<?> createGenericConfiguration(BootstrapState state) 
 {
    return new ConfigurationImpl(state);
 }

ConfigurationImpl类有一个静态初始值设定项块

static
 {
     Version.touch();
     log = LoggerFactory.make();
  }

LogFactory类释放org.jboss.logging.Logger。

因此，将jboss-logging-3.2.0.Final.jar添加到依赖项中，就完成了。
