Mastering Java: Key Senior Java Backend Developer Skills
A senior Java developer should have excellent technical skills in Java, Spring Boot, databases, web applications, and web services. He should also have experience using development tools such as Maven, Git, and Eclipse and testing frameworks like JUnit and HTML. He must also be experienced in Scrum and Jenkins, as these enable continuous integration and deployment.
Below is the list of the most critical senior Java backend developer skills. We ranked the top senior Java backend developer skills based on the percentage of resumes they appeared on.
Continue reading to learn the essential skills of a senior Java backend developer to succeed in work.
1. Java
Java is a programming language used to create computer programs. Senior Java applications involve business logic, CMS, and web services.
Java further extends its use for user interfaces, database interactions, and handling enormous data.
Senior Java developers apply Java as follows:
- Developed a common client validation framework using JavaScript.
- Design and Develop a Java-based Content Management Contingency Framework incorporating Spring Boot.
2. Springboot
Spring Boot is a popular web application development framework. Senior Java Developers use it to avoid boilerplate configuration as much as possible, providing an application that will mostly leverage convention over configuration; they use it for security and externalized configuration.
It implements batch configurations and interacts with other services via REST and message brokers. It also implements cross-cutting concerns such as business transactions, security, and logging.
They implement cross-cutting concerns through business transactions, security, and logging.
Here’s how leading Java developers use Spring Boot.
- They reduced boilerplate configuration using Spring Boot, which supports embedded Tomcat and dependency management.
- Configured applications using Spring Boot and Spring Security for authentication and authorization purposes.
3. Database
Databases are a collection of data; a computer can access databases quickly.
Senior Java developers use databases to store or retrieve data. They actually design and create database objects such as tables, views, and stored procedures and often use Hibernate to interact with the database to map it to a relational database to update data in the data access layer using Spring-Hibernate-JPA.
Here is how senior Java developers use databases:
- Used Hibernate Annotation Configuration to achieve database connectivity.
- Developed a 3-tier architecture that met the client requirements and segregated database, business, and client logic.
4. Web Application
A web application is software that interacts with users through a web browser. Using web applications includes designing and developing, automating, and deploying.
Senior Java Developers will also use web applications to exchange information between different agencies and build single-page, cross-browser-compatible applications.
An example is developing a web application using Spring MVC and injecting dependencies using Spring Auto Wiring Modes.
Here is how senior Java developers use web applications:
- Project Description: It is a web application that business customers can surf through and order online communication products and services of business customers.
- Designed and developed a web application to facilitate the exchange of information between different agencies using Spring framework and Web Services. MVC
5. MVC
Model-view-controller is a technique for application architecture. Senior Java developers base the writing of user interfaces on configuration settings, updated files, and integrated business logic.
They design and generate JSP pages, implement navigation, and set up controllers using Spring MVC annotations. They also apply MVC to write applications and integrate them with other technologies like DAO layers, Node JS, and Angular JS.
Here’s how the senior Java developers made use of MVC:
- Designed and developed generated JSP pages based on Struts MVC architecture and updated configuration settings in configuration files.
- Implemented navigation using Spring MVC controllers and configured controllers through Spring MVC annotations and configuration files.
6. Maven
Maven is the one development tool that provides the ideal environment for building, managing, and deploying software applications.
The senior Java programmers use Maven to automatically build and deploy application artifacts by engaging in activities such as building/deploying/troubleshooting; they create and then customize build scripts alongside implementing logging mechanisms.
In addition, they use Maven tools for Continuous Integration and automation build tools, manage the project’s dependencies, and deploy the whole project to application servers.
Here is how senior Java developers utilize Maven:
- Configured Maven configurations for automated build and application artifact deployment.
- Developed build scripts and performed build/deploy/troubleshoot activities using Maven.
