Read an article on the Internet that this is a bug in the assembly package spring project. See also (http://www.cnblogs.com/liqiu/p/4508848.html)
It is said that the reason is that more than one jar package in spring contains Spring.handlers and Spring.schemas files, and assembly only the first encountered files into the jar package, the later encountered will skip.
The solution is to abandon assembly and use shade Plug-in to package. The Spring.handlers and Spring.schemas files are included in the shade packaging configuration to ensure that the information of the two files in other spring jars is not omitted.
Here is a very simple example of a MAVEN project with only four files, in the code re-attachment:
Spring MAVEN projects packaged as executable jar packages
