Question

我正在关注Spring MVC的教程，在尝试实现Hibernate验证之后，我现在在服务器上运行应用程序时得到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，它没有任何问题地提供了主页（我必须在Customer对象类中评论Hibernate验证注释）但是当我将它们添加回来时（注释）仍然评论）我再次收到错误！

有没有人知道为什么Hibernate Jars导致了这个错误？

Tomcat版本：7.0.67
Java版本：1.8.0_131

Answer 1

查看您提供的异常以及您的pom文件，看起来您似乎缺少

<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）同时我注意到对于验证器你有6.0.0.Final作为版本 - 你最好全部版本一致。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。

Answer 2

我遇到了同样的问题，问题出在Tomcat 7上。使用货物解决了问题。使用javax.el和javax.el-api

的依赖项

 <!-- 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>

添加货物插件以运行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

Answer 3

有时问题不是关于我的问题的依赖关系，我使用的是 Tomcat 7 然后我使用 tomcat 9 它有效。写作，以便如果有其他人必须尝试我的解决方案

Hibernate Validator 6.0.8 jar导致异常
