Eclipse loads spring and struts2

Spring link:

Http://s3.amazonaws.com/dist.springframework.org/release/SPR/spring-framework-3.0.5.RELEASE.zip

 

After the download is complete, decompress the package to the appropriate directory. We recommend that you put the package in the eclipse directory.

There are two import methods. recommended method 1.

Method 1:

Preferences-> JAVA-> build path-> User Libraries

• A new user library named spring
• Add jars to add the jar package that has been decompressed to spring.
• Click OK. OK.

• Left-click Project name-> Properties

Java build path-> Add library-> User library-> next

Select the previously added user library and finish

The spring library is imported successfully.

Method 2:

Directly import the spring library file to the Java build path attribute of the project.

An error is reported when the spring test program is run after the spring library is imported:

It is found that the Spring-dependent commons-logging library is missing.

Commons-logging Library: http://commons.apache.org/logging/download_logging.cgi

After you import commons-logging in the same way, the program runs correctly.

Scatter flowers!

It is similar when eclipse loads struts2.
