Spring 创建名为'；默认验证器'；在类路径资源中定义

我试图在JBOSS上部署spring boot应用程序时遇到以下错误。不过，它在嵌入式Tomcat服务器上运行良好。我试图浏览堆栈溢出以找到类似的问题。尚未找到解决方案。如有任何建议，将不胜感激。谢谢

当我试图运行我的spring boot应用程序时，我也遇到了同样的问题。经过大量搜索，我发现我的问题是pom.xml文件中可能缺少Spring JPA、Hibernate、Mysql或jackson。所以我刚刚添加了这个依赖项，它工作得很好

org.springframework
春季甲虫
org.hibernate
休眠实体管理器
mysql
mysql连接器java

在Java 9模块化应用程序中尝试使用spring boot时，我遇到了相同的错误。最后，我不得不要求

com.fasterxml.classmate

。我设法用echo控制器启动了一个rest api，该控制器具有以下pom依赖项和模块信息：

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

我将[Bean Validation API]依赖项更新为最新版本。它解决了我的问题

<!-- https://mvnrepository.com/artifact/javax.validation/validation-api -->
<dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>
    <version>2.0.1.Final</version>
</dependency>

javax.validation
如果spring引导无法自动配置bean，则会从org/springframework/boot/autoconfigure/validation/package抛出错误。此错误的可能原因包括依赖项不匹配、依赖项中断或缺少依赖项。以下是解决方案

通过右键单击您的项目来更新maven项目，向下滚动到maven并在侧栏中选择Update maven project。选中强制更新快照/发布复选框并单击确定（Eclipse/STS IDE）。这将更新依赖项并生成项目，以修复依赖项相关的问题

如果错误没有得到解决，您还可以尝试通过向pom文件添加依赖项来手动更新bean验证api。

我有下面同样的例外。我使用Tomcat7部署了一个SpringBootWeb应用程序。我把它改成tomcat 8，它就解决了。
但很明显，在大多数情况下，更换服务器并不是一个简单可行的解决方案。
为java.lang.NoClassDefFoundError添加缺少的依赖项：javax/el/ELManager将解决此问题

原因：org.springframework.beans.factory.BeanCreationException:创建名为“defaultValidator”的bean时出错，该名称在类路径资源[org/sprin gframew/boot/autoconfigure/validation/ValidationAutoConfiguration.class]：通过工厂方法实例化bean失败；嵌套异常为org.springframe work.beans.BeanInstantiationException:未能实例化[org.springframework.validation.beanvalidation.LocalValidatoryBean]：工厂方法“defaul tValidator”引发异常；嵌套的异常是java.lang.NoClassDefFoundError:javax/el/ELManager
在org.springframework.beans.factory.support.ConstructorResolver.instantiate（ConstructorResolver.java:656）
我在springboot2.0中通过在build.gradle中添加org.springframework.boot:spring boot starter验证解决了这个问题
NoSuchMethodError
几乎总是意味着不匹配的依赖项版本。您可能存在依赖项问题：您找到了解决此问题的解决方案吗？请在JBoss中查找验证api实现（jar）。
