Problem:
The annotated code in eclipse can still be executed when debug. At that moment the heart was broken.
Solution:
Project recompile display is normal, and there is no error, and then found that the project compiled, web-inf/lib/classes in the class file and did not update, it is good to understand that the project is not actually compiled successfully. Then you find an exclamation point on the project icon. This is because some of the jars in the right key →properties→libraries of the project are incorrect, resulting in the project not being able to compile automatic generation classes.
Loading the jar project is normal.
Over..
The above is a quick solution to the comments in eclipse the code will still be implemented by the small series to share all the content, I hope to give you a reference, but also hope that we support the cloud habitat community.
