Spring Boot（嵌入式Tomcat未启动）

尝试启动Tomcat时出现一个通用错误。下面是StackTrace：

您声称正在调试Tomcat引导程序，但是您在属性和插件中指定了一个jetty实例。

我会尝试从POM中删除以下元素：

<plugin>
        <groupId>org.mortbay.jetty</groupId>
        <artifactId>maven-jetty-plugin</artifactId>
        <version>6.1.10</version>
        <configuration>
            <contextPath>/</contextPath>
        </configuration>
    </plugin>
    <plugin>
        <groupId>org.eclipse.jetty</groupId>
        <artifactId>jetty-maven-plugin</artifactId>
        <version>9.2.1.v20140609</version>
        <configuration>
            <httpConnector>
                <port>8088</port>
            </httpConnector>
   </configuration>
</plugin>

并将properties元素替换为：

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
        <start-class>com.package.leading.up.to.StartingClassApplication</start-class>
    </properties>
