标签： java spring gradle spring-boot noclassdeffounderror

我使用网站http://start.spring.io/

创建了spring-boot应用程序

现在当我gradle build时，我看到了以下内容：

gradle build

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看起来像这样：

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了司机：

enter image description here

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

中看到此类

我的配置有什么问题？

P.S。

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

但它仍会产生同样的错误。

1 个答案:

答案 0 :(得分：1)

更换

后问题消失了 
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');
