Relation does not exist, Spring Boot postgresql
Question
I am attempting to create an application with Spring Boot and I cannot figure out what I am doing wrong. I believe it stems from my entity design but I am not sure how to go about fixing it. I have two entities that I want to be linked to. The aircraft entity must have a one-to-many relationship with the discrepancy entity. In my repository, I am using the JPA repository and the find-all method.
When using postman to send a get request to retrieve all aircraft objects, I receive this error.
org.postgresql.util.PSQLException: ERROR: relation "aircraft.aircraft" does not exist
Position: 152

信息很明确：您在“飞机”模式中没有名为“飞机”的表/视图，该表是否存在于“公共”模式中？

This can be because the table is not present in your schema in the database.
In order to resolve this, you can set this property in the application.properties file
spring.jpa.hibernate.ddl-auto= update
This property if the table does not exist then it will create or if the table exists then alter the table.
Hope the problem is Solved.
