The reason for this is: I used the JDK8.0 version, and Spring uses 3.2.
The workaround is to reduce the build version of the project to 1.7.
Specific as follows:
Right-click on the project –properties–java Compile–compiler compliance level:

When you set up a compiled version, there will be a red fork on the project, but this will not affect the operation of the project.

=================================
The original English explanation is as follows:

You need Spring 4 if your want compile code to Java 8 (--target 1.8), but can still run apps on Java 8 compiled to Java 7 If you run on Spring 3.2.X.
