Caused by: org.springframework.boot.context.properties.ConfigurationPropertiesBindException: Error creating bean with name 'druid': Could not bind properties to 'DataSource' : prefix=spring.datasource, ignoreInvalidFields=false, ignoreUnknownFields=true; nested exception is org.springframework.boot.context.properties.bind.BindException: Failed to bind properties under 'spring.datasource' to javax.sql.DataSource

经过仔细查看日志：
发现了有这么一个错误提示

  1. Caused by: java.lang.ClassNotFoundException: org.apache.log4j.Priority
  2.     at java.net.URLClassLoader.findClass(URLClassLoader.java:382)
  3.     at java.lang.ClassLoader.loadClass(ClassLoader.java:424)
  4.     at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:349)
  5.     at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
  6.     ... 107 more

这个ClassNotFoundException提示不就是告诉我们少了log4j吗
于是解决方法：导入下面的依赖，成功解决

  1. <dependency>
  2.             <groupId>log4j</groupId>
  3.             <artifactId>log4j</artifactId>
  4.             <version>1.2.17</version>
  5.         </dependency>
