Spring Boot 2.0 was finally released on May 1, 2018, and my blog has been upgraded to it from Spring Boot 1.5.9.
Spring Boot 2.0 is a major update of 17 months’ work. It breaks some configurations due to refactoring and dependency updates along with it.
When updating many-to-many relationships, the SQL executed by JPA may be quite inefficient.
Suppose we have a Post-Tag association: each post can have multiple tags, and each tag can also has multiple posts.
I have been planning to build my own blog (previously it was powered by WordPress) for a long time, and now it finally comes.
The new blog is build with Spring Boot.
