維基百科的創(chuàng)始人說過一個理論，如果一個事物在google上查不到，那基本上就說明這世界上沒這個事物。我今天偏偏需要了一個google都搜不到的exception.
我在寫一個用spring boot的應用，需要了這個exception:

The solution is: in the pom.xml, instead of using
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.3.0.BUILD-SNAPSHOT</version>
</parent>
Use a specific version:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.2.4.RELEASE</version>
</parent>
