Question

我有一个Spring-mogodb-rest应用程序，我根据教程构建。它很有用。我想把GeoJsonPoint添加到我的类中，为此我需要将org.springframework.data添加到我的pom中。问题是 - 一旦我添加它（甚至在我将GeoJsonPoint添加到我的类之前），Tomcat将无法启动。

我的pom是

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        </dependency>

        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

    </properties>

        </plugins>
    </build>

</project>

我标记（带有评论）导致问题的依赖性。

我尝试启动时收到的错误消息（...的开头是

您已经包含了spring-boot-starter-data-mongodb，因此您不需要为spring-data-mongodb指定显式依赖项，因为这是spring-boot-starter的传递依赖项。如果使用版本显式定义依赖关系，则可能会引入依赖关系版本冲突。

无法将org.springframework.data添加到我的pom.xml中
