java - 无法加载 ApplicationContext ...创建名为 'entityManagerFactory' 的 bean 时出错 ...NoClassDefFoundError : org/dom4j/io/STAXEventReader

Question

我使用网站 http://start.spring.io/

创建了 spring-boot 应用程序

现在，当我执行 gradle build 时，我会看到以下内容:

gradle build

:assemble                 
:compileTestJava UP-TO-DATE

com.dataart.ObjectSharingSystemApplicationTests > contextLoads FAILED
    java.lang.IllegalStateException
        Caused by: org.springframework.beans.factory.BeanCreationException
            Caused by: java.lang.NoClassDefFoundError
                Caused by: java.lang.ClassNotFoundException

1 test completed, 1 failed                         
:test FAILED

实际上这个测试是空的，看起来像这样:

@RunWith(SpringRunner.class)
@SpringBootTest
public class ObjectSharingSystemApplicationTests {

    @Test
    public void contextLoads() {
    }

}

application.properties 如下所示:

spring.datasource.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.datasource.url=jdbc:sqlserver://localhost:1433;database=objectSharing
spring.datasource.username=test
spring.datasource.password=test

对我来说也很奇怪，这个想法用红色突出显示驱动程序:

实际上这个类存在于类路径中。如果我将地址粘贴到 CTRL+N 菜单 - 我会在 mssql-jdbc-6.1.0.jre8.jar

中看到该类

我的配置出了什么问题？

我尝试添加 compile('org.hibernate:hibernate-entitymanager')

但它仍然产生相同的错误。

依赖关系:

Answer 1

更换后问题消失

compile('org.springframework.boot:spring-boot-starter-data-jpa')

与

compile('org.springframework.boot:spring-boot-starter-data-jpa') {
    exclude module: 'dom4j'
}
compile('dom4j:dom4j');
