Web Development Using Spring Boot For Beginners

By -

In this series of posts, we are gonna cover tutorial on how to get start web development in Java using spring boot. For your information, I've been working on web developments for quite a while but not using Spring, and not using Java either, so it's kinda like i am also newbie as you are, but don't worry all codes on this website will be tested so that it will work when you copy/pasting. And because it's for beginners, all codes on this series would be full single class file, no cut.

Follow these steps to get started web development in Spring.

1. Prepare your favorite IDE
It is Java not Javascript, you are gonna write enterprise level codes, in other to have readable, maintainable codes, you need to have better tools, IDE helps you refactoring your code, code completion, and building your code with a press of a button, usually hammer icon.

2. Initialize spring boot project
Simply using start.spring.io, you can create your project template, all you need to do is specifying project meta data, dependencies you want to use, etc.

Add dependencies, i will recommend these dependencies for your starter:

Web, JPA, MySQL, devtools

Then download the zip file given, extract the file to where you usually placed your projects

3. Build the project
I suggest open a terminal or cmd, then locate using cd command, for example

cd your-spring-project

Then

mvn clean install

4. Start using IDE
Open your project from your IDE, because you already build the project on the step 3, the IDE usually not compiling your project again, so it will open your project faster.

5. Set database configuration
If you include MySQL dependencies, you must change the application.properties, located on your-project/src/main/resources at minimal have these MySQL configuration:

spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.initialization-mode=always
spring.datasource.password=1234
spring.datasource.url=jdbc:mysql://localhost:3306/your_database?autoReconnect=true&useSSL=false
spring.datasource.username=root

6. Run the projects
Switch to cmd again, and don't forget to locate to your project directory using cd command, then using this command to run the project, and don't close it.

mvn spring-boot:run

Now you are ready to develop your spring boot application using your favorite IDE, every change you made, just build the project by click the hammer button, it will auto reload your project because you have devtools on your pom.xml.


You can check using your favorite browser, go to http://localhost:8080 to make sure your project is running.

MySQL and MariaDB password As already mentioned in the title of this blog, this error message sometimes occurred when we are trying to update our root password database, either MySQL or MariaDB, The error says: ERROR 1348 (HY000): Column 'Password' is not updatable This is because if we use this SQL command to update our database root password, and it turn out to be Restricted by MySQL to use update on mysql database. UPDATE mysql.user SET Password=PASSWORD('1234') WHERE User='root'; The solutions for MySQL Error1348 So you can not update a user password using Update commands, to update the password, use ALTER commands instead. like the following. ALTER USER 'root'@'localhost' IDENTIFIED BY '1234'; And then you need to do the flush privileges to commit previous queries (that alter command above) into the system, simply do like this. flush privileges; So now you have your root with password 1234. Although it is recommended to

Spring Kafka - how to use ReplyingKafkaTemplate send and reply synchronously

By -

Microservice Spring with Apache Kafka Kafka is an asynchronous messaging queuing system, but when you have a case in your project that you need to have the result immediately from another service you can do that quite easily. Kafka from the client side produces a message to the server side, then waiting for the server to return back the message exactly what the client wants. It’s identified in the kafka header request named KafkaHeaders.CORRELATION_ID and a topic where the server should send. If the server side produces the same correlation id to the same topic in the request, then the client side will catch that message as its reply. Although you can work with kafka from a different framework and language other than Java and Spring. Here’s in this example i just specifically giving the example of sending and replying kafka messages using Spring Boot. The Project Overview The client-project will send a string message to the server-project over kafka, then the server-project wil

Reactive Spring Logo This is maybe a very simple task, but for those of you that may not be familiar with WebFlux found it difficult to create a Rest API that handles upload and download in Reactive spring application. Create the skeleton Spring project Create a new project, go to start.spring.io , on the dependencies section, add Spring Reactive Web. Generate and extract it into your desired project location. Instead of using spring-boot-starter-web, use spring-boot-starter-webflux instead in your pom.xml. Here’s the pom.xml for our Reactive Rest API project. Create our Rest controller Now that you have set to use WebFlux instead of the usual web, we have to change a little bit in the Controller class that handles the API endpoints. It doesn’t change much but you have to wrap the Response in Mono and the request parameter to FilePart. So our upload and download file controller will look like this. Create utility to handle file upload We need to structure our project better, so we cr
