[JAVA] Tests with @Parameters in Spring 4.3 should have no parameters

phenomenon

When I upgrade Spring Boot to 1.4 series, the test with @Parameters of JUnitParams fails with Initialized Error with the message should have no parameters`.

solution

Change Runner to @RunWith (JUnitParamsRunner.class)

background

--It seems that the implementation of the constructor of SpringJUnit4ClassRunner has changed from the Spring Framework 4.3 series that depends on SpringBoot 1.4. --Until 4.2, @Parameters worked on SpringJUnit4ClassRunner, but it stopped working from 4.3.
