nacos报错java.lang.ClassNotFoundException: com.netflix.config.DynamicPropertyFactory解决方案

问题背景

使用LoadBalancerClient报错java.lang.ClassNotFoundException: com.netflix.config.DynamicPropertyFactory

java.lang.ClassNotFoundException: com.netflix.config.DynamicPropertyFactory
	at java.net.URLClassLoader.findClass(URLClassLoader.java:382) ~[na:1.8.0_221]
	at java.lang.ClassLoader.loadClass(ClassLoader.java:424) ~[na:1.8.0_221]
	at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:349) ~[na:1.8.0_221]

解决方案

1 找不到类,说明没有引入这个依赖,然后看了一下nacos引入了,,但排除了很多依赖,这个核心被排除掉了,所以报错

                <exclusion>
                    <artifactId>archaius-core</artifactId>
                    <groupId>com.netflix.archaius</groupId>
                </exclusion>

2 正常引入的依赖,因为引入了其他很多东西,所以排除了,很多根据自己需要把排除删除掉
