The test is normal, but in the project, the following error will be reported, which should be caused by class conflicts.

Exception in thread "Main" Java. Lang. nosuchmethoderror: org. Apache. Poi. poidocument. <init> (lorg/Apache/poi/poifs/filesystem/directorynode;) V

Solution: Open properties-> JAVA build path-> order and export of the project, find that the two jar packages of POI are put to the end, and move the poi package to the top. Solve the problem!
