错误日志

Question

我试图写一个简单的单元测试。此测试函数将调用我的服务，该服务从数据库中获取信息，将其推送到列表并返回它。我在调试日志中看起来很高和很低，以找到可能导致的结果，但似乎网络上的任何内容都没有帮助我。我对Spring Boot不太熟悉，但似乎令人惊讶的是，所有这些努力和我无法通过简单的单元测试。

Answer 1

异常的真正原因是

java.lang.ClassNotFoundException: javax.xml.bind.JAXBException

所以我相信你需要将JAXBE库添加到你的类路径中（它已经从java9中的JDK中删除了，我想你使用的是java9）

尝试将其添加到您的pom文件

<!-- https://mvnrepository.com/artifact/javax.xml.bind/jaxb-api -->
<dependency>
  <groupId>javax.xml.bind</groupId>
  <artifactId>jaxb-api</artifactId>
  <version>2.3.0</version>
</dependency>

Answer 2

<强> JDK

/Library/Java/JavaVirtualMachines/jdk-9.0.1.jdk/Contents/Home/bin/java

<强>的pom.xml

1.8

您使用的是java 8还是9？

org.springframework.beans.factory.BeanCreationException：错误在类路径中定义名为'entityManagerFactory'的bean 资源 [组织/ springframework的/引导/自动配置/ ORM / JPA / HibernateJpaAutoConfiguration.class]：调用init方法失败;嵌套异常是 java.lang.NoClassDefFoundError：javax / xml / bind / JAXBException

java.lang.NoClassDefFoundError：javax / xml / bind / JAXBException ，

的问题

使用Java 8环境运行应用程序或包含Java 9的JAXB库，JAVA SE 9中不包含JAXB API。请参阅Deprecated, for removal: This API element is subject to removal in a future version.。使用--add-modules（ - add-modules java.xml.bind ）在类路径中添加模块。 Jave只是弃用了，默认情况下不会在classpath上添加javax.xml.bind模块。

否则通过maven包含依赖性。

<dependency>
  <groupId>javax.xml.bind</groupId>
  <artifactId>jaxb-api</artifactId>
  <version>2.3.0</version>
</dependency>
