spring-projects#278 - Fix entity characteristics in Customer in Eclipselink example.

odrotbohm · odrotbohm · commit 7870a7e060eb · 2017-06-19T09:51:03.000+02:00
We now calculate the equals(…) and hashCode() methods by looking at the indentifier only. Removed default constructor in favor of Lombok's @NoArgConstructor.
