Master Hibernate and JPA with Spring Boot in 100 Steps - Step 63 - Implementing Transaction Management - 3 Things to Dec

The video tutorial discusses the use of transactional annotations in the Spring Framework and JPA, highlighting the differences and use cases for each. It explains how JPA is suitable for single database transactions, while Spring is recommended for managing transactions across multiple databases and external interfaces. The tutorial also covers setting isolation levels in Spring transactions and configuring default isolation levels in Hibernate.

What is the primary use of JPA's transactional annotation?

• Managing transactions across multiple databases

• Handling transactions within a single database

• Sending messages over MQ

• Configuring isolation levels

Why is Spring's transactional annotation preferred for complex transaction management?

• It is easier to implement

• It supports transactions across multiple databases and queues

• It is faster than JPA's annotation

• It requires less configuration

Which isolation level ensures that a transaction can read only committed data?

• Serializable

• Repeatable Read

• Read Committed

• Read Uncommitted

How can you set the default isolation level for all transactions in a Hibernate connection?

• By setting a property in the database

• By modifying the Java SQL connection

• Through the hibernate.connection.isolation property

• Using a Spring configuration file
