Difference between Spring Boot QuartzAutoConfiguration 2.1.6.RELEASE & 2.2.2.RELEASE

Question

We were using Spring Boot 2.1.6.RELEASE. after that we updated spring version to 2.2.2.RELEASE. When we change the version we noticed our quartz jobs not working. We have multiple jobs and we configured them like below. After some reasearch i found some differences between in QuartzAutoConfiguration class. How can i inject my triggers in spring 2.2.2.RELEASE. Is there any easy way? I dont want to write to many triggers and trigger details.

QuartzAutoConfiguration.java Spring version 2.1.6 github url ; https://github.com/spring-projects/spring-boot/blob/v2.1.6.RELEASE/spring-boot-project/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/quartz/QuartzAutoConfiguration.java

QuartzAutoConfiguration.java Spring version 2.2.2 github url https://github.com/spring-projects/spring-boot/blob/v2.2.2.RELEASE/spring-boot-project/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/quartz/QuartzAutoConfiguration.java

Main difference i notice is ; in 2.1.6 version Quartz AutoConfiguration was "Trigger" array but 2.2.2 doesn't have "Trigger" array.

Spring has always some magic :)
