java - Spring Boot 错误激活 Bean 验证集成

Question

我正在尝试启动我的网络应用程序，但出现了这两个错误:

2020-12-22 20:46:25.769  INFO 23060 --- [           main] org.hibernate.dialect.Dialect            : HHH000400: Using dialect: org.hibernate.dialect.MySQL5Dialect

这里是最终错误输出的描述:

描述:

试图调用不存在的方法。尝试是从以下位置进行的:

javax.el.ELManager.getExpressionFactory(ELManager.java:38)

不存在以下方法:

javax.el.ELUtil.getExpressionFactory()Ljavax/el/ExpressionFactory;

该方法的类 javax.el.E​​LUtil 可从以下位置获得:

jar:file:/C:/Users/chafy/Desktop/backend/lib/javax.servlet.jsp.jar!/javax/el/ELUtil.class
jar:file:/C:/Users/chafy/.m2/repository/org/glassfish/jakarta.el/3.0.3/jakarta.el-3.0.3.jar!/javax/el/ELUtil.class
jar:file:/C:/Users/chafy/.m2/repository/javax/el/javax.el-api/3.0.0/javax.el-api-3.0.0.jar!/javax/el/ELUtil.class
jar:file:/C:/Users/chafy/.m2/repository/org/glassfish/javax.el/3.0.0/javax.el-3.0.0.jar!/javax/el/ELUtil.class

类层次结构是从以下位置加载的:

javax.el.ELUtil: file:/C:/Users/chafy/Desktop/backend/lib/javax.servlet.jsp.jar

行动:

更正您的应用程序的类路径，使其包含一个单一的、兼容的 javax.el.E​​LUtil 版本

我试图通过添加许多依赖项来解决它，但什么也没有。有人说是 servlet 版本问题，其实不是。

Answer 1

所以，我不知道确切的问题，但也许我可以给你一些要看和/或尝试的东西。

一般来说，servlet、jsp、el库应该由你的容器来提供。所以，我会考虑添加 <scope>provided</scope>到您不同的 servlet 库:

<!-- Provided by Tomcat Container -->
<dependency>
    <groupId>javax.el</groupId>
    <artifactId>javax.el-api</artifactId>
    <version>3.0.0</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.0</version>
    <scope>provided</scope>
</dependency>

而且由于您使用的是 Tomcat，我将删除对 org.glassfish.javax.el 的直接使用图书馆。我认为每个容器都提供了自己的 el 库实现，拥有第二个库可能会导致类路径问题。

(最有可能)从 pom.xml 中删除:

<dependency>
    <groupId>org.glassfish</groupId>
    <artifactId>javax.el</artifactId>
    <version>3.0.0</version>
</dependency>

Hibernate Validator 也有点麻烦。 From this answer on a similar problem :

Hibernate Validator 6.x -> Bean Validation 2.0 (JSR 380) -> EL3.0

Hibernate Validator 5.x -> Bean Validation 1.1 (JSR 349) -> EL2.2

Bean Validation 1.0 (JSR 303) -> (I'm not sure)

因此，理论上，您应该使用 Hibernate Validator 6 而不是像现在这样的版本 5。
