Note on bugs in the Java compilation process

Today, I found that the compilation failed after I updated the code submitted by the brothers in the group
The exception information is as follows:
The method getPOIByName(String) of type POISearchByGeoway must override a superclass method
I've seen this before, so I thought I'd write a blog about it to make it easier for anyone!
Ok solution is as follows:
1. Right-click project > Build Path> Configure Build Path > > JAVA Compiler  Compiler Compliance level& assignment; Change to 1.6 (the Override annotation does not appear until Java 1.6).

2, Windows> Preferences> Java> Complier modifier Compiler Compliance level& Compliance; Instead of 1.6.
