原因在于：ConfigFileApplicationListener 没有实现 SmartApplicationListener 接口的方法：

public class ConfigFileApplicationListener
      implements EnvironmentPostProcessor, SmartApplicationListener, Ordered {

supportsSourceType（） // 没实现

 

根本原因在于版本依赖错误

[INFO] |  +- org.springframework.boot:spring-boot-starter:jar:2.1.0.RELEASE:compile
.....

[INFO] |  \- org.springframework.amqp:spring-rabbit:jar:2.1.0.RELEASE:compile

[INFO] |     +- org.springframework:spring-context:jar:5.0.8.RELEASE:compile

查看 parent 项目pom.xml，发现两处版本定义不一致：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.0.RELEASE</version>
    <relativePath/>
</parent>

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-dependencies</artifactId>
    <version>2.0.4.RELEASE</version>
    <type>pom</type>
    <scope>import</scope>
</dependency>

解决：

<parent> 和 <dependency> 只需要二先一，定义了parent就不需要再加dependency
