Hibernate Validator 6.0.8 jars 导致异常答案

【问题标题】：Hibernate Validator 6.0.8 jars causing exceptionHibernate Validator 6.0.8 jars 导致异常
【发布时间】：2018-03-20 21:36:55
【问题描述】：

我正在学习有关 Spring MVC 的教程，在尝试实现 Hibernate 验证后，我现在在服务器上运行应用程序时收到 HTTP Status 500 - Servlet.init() for servlet dispatcher threw exception。

我从 POM.xml 中取出了 3 个 Hibernate jar 依赖项，它提供了主页而没有任何问题（我必须在 Customer 对象类中注释 Hibernate 验证注释）但是当我将它们添加回来时（注释仍然被评论）我又得到了错误！

有人知道为什么 Hibernate Jars 会导致这个错误吗？

Tomcat 版本：7.0.67
Java 版本：1.8.0_131

标签： java spring-mvc hibernate-validator

【解决方案1】：

查看您提供的异常以及您的 pom 文件，您似乎丢失了

<dependency>
    <groupId>org.glassfish</groupId>
    <artifactId>javax.el</artifactId>
    <version>3.0.1-b09</version>
</dependency>

它是 EL 的一个实现，所以你需要添加它（并且可能删除 api 那个）我还注意到，对于验证器，你有 6.0.0.Final 作为一个版本 - 你最好拥有所有版本一致。对于 Spring 中的简单验证，它应该足够了：

<dependency>
    <groupId>org.hibernate.validator</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>6.0.8.Final</version>
</dependency>

和上面提到的EL依赖。

【讨论】：

我在谷歌搜索时确实遇到了这种依赖关系，并将其添加到 POM.xml 中，然后再发布我的问题。我在那里再次尝试并替换了现有的 javax.el 但没有运气。啊，是的，它最初是 6.0.8，我将其切换到早期版本，看看是否有帮助.. 遗憾的是没有。
你能不能试试mvn dependency:tree看看有没有冲突的jar？
这很方便我在调试时没有遇到那个命令！有趣的是，我收到了一个验证器 jar 的警告 - [警告] 工件 org.hibernate:hibernate-validator-cdi:jar:6.0.8.Final 已重新定位到 org.hibernate.validator:hibernate-validator-cdi :jar:6.0.8.Final
我在 Hibernate Validator 迁移指南上找到了这一点 - “为了简化迁移，将为 HV 6 发行系列提供重定位工件。如果您看到类似“[WARNING”的消息，请检查构建的输出] 工件 org.hibernate:hibernate-validator:jar:6.0.0.Alpha1 已重新定位到 org.hibernate.validator:hibernate-validator:jar:6.0.0.Alpha1"，您仍在使用旧的 GAV 坐标和应该升级到新的。”知道如何升级我的 GAV 坐标吗？
@algorhythm 所以关于 GAV 的事情，只是 HV 6 的组 ID 发生了变化。以前是 <groupId>org.hibernate</groupId>，现在是 org.hibernate.validator，最后是验证器。

【解决方案2】：

我遇到了同样的问题，问题出在 Tomcat 7 上。使用 cargo 解决了这个问题。使用javax.el和javax.el-api的依赖

 <!-- https://mvnrepository.com/artifact/org.glassfish/javax.el -->
    <dependency>
        <groupId>org.glassfish</groupId>
        <artifactId>javax.el</artifactId>
        <version>3.0.1-b09</version>
        <!--<scope>provided</scope>-->
    </dependency>

    <!-- https://mvnrepository.com/artifact/javax.el/javax.el-api -->
    <dependency>
        <groupId>javax.el</groupId>
        <artifactId>javax.el-api</artifactId>
        <version>3.0.0</version>
    </dependency>

添加 cargo 插件来运行 tomcat。

 <build>
    <plugins>
        <plugin>
            <groupId>org.codehaus.cargo</groupId>
            <artifactId>cargo-maven2-plugin</artifactId>
            <version>1.6.5</version>
            <configuration>
                <container>
                    <containerId>tomcat8x</containerId>
                    <zipUrlInstaller>
                        <url>http://repo1.maven.org/maven2/org/apache/tomcat/tomcat/8.5.9/tomcat-8.5.9.zip</url>
                    </zipUrlInstaller>
                </container>
            </configuration>
        </plugin>
    </plugins>
</build>

使用以下运行配置。

cargo:run

【讨论】：

对于 Cargo，我使用的是 tomcat 8 而不是 tomcat 7

【解决方案3】：

有时问题与我的问题无关，我使用的是 Tomcat 7，然后我使用的是 tomcat 9 它有效。写这样如果有其他的必须尝试我的解决方案

【讨论】：

如果您可以添加更多信息供其他人参考，那就太好了
