解决问题思路

首先，确定Spring Cloud Hoxton.SR1与Spring boot 2.2.2.RELEASE是否匹配，查询官网https://cloud.spring.io/spring-cloud-static/Hoxton.SR1/reference/htmlsingle/

版本对应一致。

然后，查看Tomcat的Maven依赖，

Tomcat的Maven依赖也没有问题。

接着根据

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [com/alibaba/druid/spring/boot/autoconfigure/DruidDataSourceAutoConfigure.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]: Factory method 'dataSource' threw exception; nested exception is java.lang.NoClassDefFoundError: org/springframework/boot/bind/RelaxedDataBinder

这一段，想到查看dataSource配置，

dataSource配置也没有问题。

最后，经过不断尝试，发现druid的版本低了。

Caused by: java.lang.NoClassDefFoundError: org/springframework/boot/bind/RelaxedDataBinder
	at com.alibaba.druid.spring.boot.autoconfigure.DruidDataSourceBuilder.bind(DruidDataSourceBuilder.java:48) ~[druid-spring-boot-starter-1.1.0.jar:na]

	at com.alibaba.druid.spring.boot.autoconfigure.DruidDataSourceAutoConfigure.dataSource(DruidDataSourceAutoConfigure.java:44) ~[druid-spring-boot-starter-1.1.0.jar:na]
	at com.alibaba.druid.spring.boot.autoconfigure.DruidDataSourceAutoConfigure$$EnhancerBySpringCGLIB$$ceb6cc85.CGLIB$dataSource$0(<generated>) ~[druid-spring-boot-starter-1.1.0.jar:na]

解决方案

将druid的版本，由

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid-spring-boot-starter</artifactId>
    <version>1.1.0</version>
</dependency>

改为

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid-spring-boot-starter</artifactId>
    <version>1.2.8</version>
</dependency>

Maven Reload，问题解决，项目正常启动。
