1. springcloud 启动 config-client 报错：

java.lang.ClassNotFoundException: 
    org.springframework.integration.config.HandlerMethodArgumentResolversHolder
    at java.net.URLClassLoader.findClass(URLClassLoader.java:381) ~[na:1.8.0_45]

2. 原因：使用的 pom 版本要为 2.0.3 。我原本是使用的 2.1.6 。

<parent> 改为：

<parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>2.0.3.RELEASE</version>
            <relativePath/>
        </parent>

完整 pom 为：

<?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"

3.重启工程，启动成功：
