Spring Boot应用程序错误！当我运行我的Spring Boot应用程序时，出现以下错误。我正在使用Spring Boot版本2.3.1

java.lang.IllegalArgumentException: Could not find class [org.springframework.boot.autoconfigure.web.EmbeddedServletContainerAutoConfiguration]
    at org.springframework.util.ClassUtils.resolveClassName(ClassUtils.java:334) ~[spring-core-5.2.7.RELEASE.jar:5.2.7.RELEASE]

    at org.springframework.core.annotation.TypeMappedAnnotation.asMap(TypeMappedAnnotation.java:284) 

我的pom.xml文件如下我尝试添加依赖项，但是它不起作用

Answer 1

在我这种情况下，此依赖项存在问题：

<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-spring-boot-starter-jaxrs</artifactId>
    <version>3.1.11</version>
</dependency>

您可以为此更改版本并添加hibernate-validator

<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-spring-boot-starter-jaxrs</artifactId>
    <version>3.3.6</version>
</dependency>

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>6.1.5.Final</version>
</dependency>
