我正在尝试将我们的项目从Spring boot 1.4.3升级到2.0.4.RELEASE；
这是我当前的pom.xml文件：

现在，当我在现有的测试用例上运行"mvn测试"时，我会得到以下错误：

我发现这个主题上的一些线程表明类路径有问题——很可能spring-core在类路径中出现了两次，但我找不到问题所在。我已经使用mvn依赖插件打印了依赖树，以帮助进行故障排除，但我没有发现任何明显的错误。请帮助：

我应该补充一下，在版本更新后，我已经在我的机器上运行了以下命令：
mvn清洁mvn-eclipse:cleanmvn eclipse:eclipse
Eclipse中的项目更新。我也许可以尝试重新导入到另一个工作区，但目前我没有想法，需要帮助。
如https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.0-Release-Notes#third-派对图书馆升级和https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.0-Migration-Guide#dependency-版本，您需要将您的Spring版本升级到5.x.
在pom.xml中，更改
<spring.version>4.3.9.RELEASE</spring.version>
至
<spring.version>5.0.8.RELEASE</spring.version>
您可能需要为主要春季版本的迁移做更多的更改。
不要将父级添加为Spring Boot，而是使用Spring Boot BOM表进行依赖项管理。
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-dependencies</artifactId>
<version>2.0.2.RELEASE</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
这样，您就不必手动添加每个依赖项的版本号。
例如：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot</artifactId>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.integration</groupId>
<artifactId>spring-integration-core</artifactId>
</dependency>
您可以从这里查看依赖项和版本的详细信息。http://central.maven.org/maven2/org/springframework/boot/spring-boot-dependencies/2.0.2.RELEASE/spring-boot-dependencies-2.0.2.RELEASE.pom
