Convert spring Source to Project + missing jar package when importing eclipse

Convert the source code to engineering:

For example, view the source code of the Spring transaction section.

Open the cmd window, switch to the Spring-tx folder, and execute the command "Gradle Cleanidea Eclipse".

Missing jar Package:

The first step: switch to the spring source Lib directory

Step two: Unzip the Spring-core-4.2.6.release.jar file in the Lib directory

Step three: Switch to the Spring-core-4.2.6.release directory extracted from the second step under the cmd window

Fourth step: Generate the required jar file using the jar command (Jar CVF spring-objenesis-repack-2.5.1.jar org\springframework\objenesis)

Fifth step: Put the generated jar package into the specified folder
