Spring和Jetty NoClassDef找到错误

-1

嗨我目前在我的弹簧应用程序上运行测试时出错。Spring和Jetty NoClassDef找到错误

的错误是：

java.lang.ClassNotFoundException: org/eclipse/jetty/util/FutureCallback

这是用弹簧和Maven我第一次让我很困惑。
我认为这是我的pom文件的问题，但我不确定。这是我的pom.xml：

更新：

问题是固定的，通过改变码头版本更近的一个

你有以下依赖添加到您的项目：

<!-- https://mvnrepository.com/artifact/org.eclipse.jetty/jetty-util --> 
<dependency> 
    <groupId>org.eclipse.jetty</groupId> 
    <artifactId>jetty-util</artifactId> 
    <version>9.3.10.v20160621</version> 
</dependency>

那么，Spring Boot的开箱即用，包括Tomcat为其嵌入式服务器，您需要删除依赖

<exclusions> 
    <exclusion> 
     <groupId>org.springframework.boot</groupId> 
     <artifactId>spring-boot-starter-tomcat</artifactId> 
    </exclusion> 
</exclusions>

，并取代它与码头

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

而且，你并不需要所有的启动依赖。 spring-boot-starter-data-rest已包含spring-boot-starter-data-jpa和spring-boot-starter-web，您也可以删除这些。

我做了这些修改，我的应用程序现在运行在码头上，但是当我运行我的测试时，它们失败，出现相同的错误 – t77

您还必须在'spring-boot-starter-test'依赖项中进行相同的更改。 – rorschach

我增加了排除，它仍然在测试上失败 – t77

确保jar文件具有您正在使用的类。您可以打开您的存储库（C：\ Users \ .m2 \ repository）导航到您的jar位置，打开jar并查看。如果该jar没有该类，请查找其他具有该类的其他依赖项，并将其添加到您的pom.xml中。
