A list of the issues I faced in making this simple project

1

Description Resource Path Location Type
Unknown pom.xml /routinetracker line 1 Maven Configuration Problem

Add the line

<maven-jar-plugin.version>3.1.1</maven-jar-plugin.version>

to pom.xml, so that it looks like:

<properties>
		<java.version>1.8</java.version>
		<maven-jar-plugin.version>3.1.1</maven-jar-plugin.version>
</properties>

If infinite references mappings are created between parent and child, such as parent -> child -> parent..., use @JsonIgnore on the child alongwith @ManyToOne.
This will ignore the infinite recursion problem.
@JsonBackReference and @JsonManagedReference can also be used. This solves the problem.

3

When using an entity called Item, be careful to import the correct class when using quick-import.
Hibernate provides a class called org.hibernate.cache.spi.support.AbstractReadWriteAccess.Item, which maybe imported by mistake.

4

If your child-table has a foreign key column having only null, and parent doesn't map to the children, make sure that the entities are actually committed to the repository.
JPA/Hibernate won't do it for you automatically! You have to save BOTH sides of the mapping.

5

If your database can't be found, well, create one!
Spring automatically creates tables for you, not databases.
