我有一个基于官方指南的简单 spring 项目来使用 Web 服务。此示例似乎针对 JDK 8，但我想使用最新的 LTS，JDK 11。

我已经修改了该pom.xml文件并添加了一些似乎已从 JDK 中删除的依赖项，即：

        <dependency>
            <groupId>org.glassfish.jaxb</groupId>
            <artifactId>jaxb-core</artifactId>
            <version>2.3.0.1</version>
        </dependency>

        <dependency>
            <groupId>org.glassfish.jaxb</groupId>
            <artifactId>jaxb-runtime</artifactId>
            <version>2.3.2</version>
        </dependency>

        <dependency>
            <groupId>com.sun.xml.ws</groupId>
            <artifactId>rt</artifactId>
            <version>2.3.1</version>
        </dependency>

        <dependency>
            <groupId>com.sun.activation</groupId>
            <artifactId>javax.activation</artifactId>
            <version>1.2.0</version>
        </dependency>

但是，我似乎无法启动应用程序，总是收到此错误：

?  spring-test git:(master) mvn spring-boot:run

我有一个时间段内用户的Lat/Lon格式的位置数据集.我想计算这些用户旅行的距离.样本数据集:
