Grokking The Spring Boot Interview

Cracking Java Interview is not easy and one of the main reasons for that is Java is very vast. There are a lot of concepts and APIs to master to become a decent Java developer. Many people who are good at general topics like Data Structure and Algorithms, System Design, SQL, and Database fail to crack the Java interview because they don't spend time to learn the Core Java concepts and essential APIs and packages like Java Collection Framework, Multithreading, JVM Internals, JDBC, Design Patterns, and Object-Oriented Programming. This book aims to fill that gap and introduce you to classical Java interview questions from these topics. By going through these questiosn and topic you will not only expand your knowledge but also get ready for your Next Java interview. If you are preparing for Java interviews then I highly recommend you to go through these questions befor your telephonic or face-to-face interviews, you will not only gain confidence and knowelge to answer the question but also learn how to drive Java interview in your favor. This is the single most important tip I can give you as a Java developer. Always, remember, your answers drive interviews, and these questions will show you how to drive Interviewer to your strong areas. All the best for the Java interview and if you have any questions or feedback you can always contact me on twitter javinpaul (http: //twitter.com/javinpaul) or comment on my blogs Javarevisited(http: //javarevisited.blogspot.com) and Java67(http: //java67.c

Java and Spring Developer Interviews are notoriously tough, not because they ask impossible algorithmic questions like Google or Amazon but because of the vast nature of Java API, Frameworks and Libraries. ! It's not enough for you to just know Java and expect that you will be able to clear Java Interviews. In order to pass the Java Interviews, you should also know essential Java frameworks like Spring, Spring Boot, and Hibernate. In my previous book, Grokking the Java Interview, I touched upon essential core Java topics like Collections, Multithreading, and Java Fundamentals and in this book, I have shared common Spring Framework questions from Job interviews. Spring Framework is the most popular and almost a standard framework for developing Java applications, both core java as well as Java web application which runs on servers like Tomcat. Like Java, Spring Framework is also very vast and there are several sub-projects like Containers, Core Spring Concepts like IoC and Dependency Injection, Spring MVC, Spring Boot, Spring Data JPA, Testing, and miscellaneous Spring APIs. This book contains frequently asked questions from essential Spring topics like 1. Container, Dependency, and IOC 2. Spring Bean Lifecycle 3. Aspect-Oriented Programming (AOP) 4. Spring MVC 5. Spring Boot Intro 6. Spring Boot Auto Configuration 7. Spring Boot Starter Dependency 8. Spring Boot Actuator 9. Spring Boot CLI 10. Spring Boot Testing 11. Spring Cloud Questions 12. Spring Data JPA 13. Spring Security These questions are a compilation of my best Spring Boto articles which have been read by millions of Java developers and it is also my 10 years of experience writing Java and Spring articles, tutorials, and interview questions. If you are preparing for Java and Spring Boot interviews then I highly recommend you to go through these Spring Boot and Spring questions before your telephonic or face-to-face interviews, you will not only gain confidence and knowledge to answer the question but also learn how to drive Java interview in your favor. This book is also useful for Java developers who are preparing for the Spring Professional Certification Exam because I have tried to answer most of the questions from the Official Spring Certification Exam guide. This means you can use this as a review study guide for your spring certification preparation as well. All the best for the Java interview and if you have any questions or feedback you can always contact me on Twitter javinpaul or comment on my blogs Javarevisited and Java67

If I need to define him in just 1 word then it would be a “Leader”. He is undoubtedly a true example of a leader, who first walks and then talks. I have seen him succeeding from very beginning, his hard work, dedication, early morning drills and late evening meetings, and for sure it was not an over night game but his consistency in efforts and ever lasting will to improve and grow has made him what he is today. - Pushkar Raj Thakur Jatin Arora is a man of integrity and courage. Having gone through so many ups and downs in his life, he never gave up on his dreams.

This book is a collection of developer code recipes and best practices for persisting data using Spring, particularly Spring Boot. The book is structured around practical recipes, where each recipe discusses a performance case or performance-related case, and almost every recipe has one or more applications. Mainly, when we try to accomplish something (e.g., read some data from the database), there are several approaches to do it, and, in order to choose the best way, you have to know the implied trades-off from a performance perspective. You’ll see that in the end, all these penalties slow down the application. Besides presenting the arguments that favor a certain choice, the application is written in Spring Boot style which is quite different than plain Hibernate. Persistence is an important set of techniques and technologies for accessing and using data, and this book demonstrates that data is mobile regardless of specific applications and contexts. In Java development, persistence is a key factor in enterprise, ecommerce, cloud and other transaction-oriented applications. After reading and using this book, you'll have the fundamentals to apply these persistence solutions into your own mission-critical enterprise Java applications that you build using Spring. What You Will Learn Shape *-to-many associations for best performancesEffectively exploit Spring Projections (DTO) Learn best practices for batching inserts, updates and deletes Effectively fetch parent and association in a single SELECTLearn how to inspect Persistent Context contentDissect pagination techniques (offset and keyset)Handle queries, locking, schemas, Hibernate types, and more Who This Book Is For Any Spring and Spring Boot developer that wants to squeeze the persistence layer performances.
