Spring Boot Starter

 Dependency management is a critical aspects of any complex project. And doing this manually is less than ideal; the more time you spent on it the less time you have on the other important aspects of the project.

Spring Boot starters were built to address exactly this problem. Starter POMs are a set of convenient dependency descriptors that you can include in your application. You get a one-stop-shop for all the Spring and related technology that you need, without having to hunt through sample code and copy-paste loads of dependency descriptors.

We have more than 30 Boot starters available.

Examples - Web Starter, Test Starter, Data JPA starter, etc.

Web Starter - First, let's look at developing the REST service; we can use libraries like Spring MVC, Tomcat and Jackson – a lot of dependencies for a single application. Spring Boot starters can help to reduce the number of manually added dependencies just by adding one dependency. So instead of manually specifying the dependencies just add one starter.

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency>

Tester Starter - For testing we usually use the following set of libraries: Spring Test, JUnit, Hamcrest, and Mockito. We can include all of these libraries manually, but Spring Boot starter can be used to automatically include these libraries.

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency>

Data JPA Starter - Most web applications have some sort of persistence – and that's quite often JPA. Instead of defining all of the associated dependencies manually – let's go with the starter instead.

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jpa</artifactId> </dependency> <dependency> <groupId>com.h2database</groupId> <artifactId>h2</artifactId> <scope>runtime</scope> </dependency>

Junit Mockito and Power Mockito

Mock vs Spy Both can be used to mock methods or fields. The difference is that  in mock, you are creating a complete mock or fake object while in spy, there is the real object and you just spying or stubbing specific methods of it . Mock vs InjectMock @Mock  creates a mock.  @InjectMocks  creates an instance of the class and injects the mocks that are created with the  @Mock  (or  @Spy ) annotations into this instance. Unit Testing Void Methods with Mockito and JUnit How to Test Void Methods  As we already know that our aim is to test void methods in a class. But it is also really important to understand why we test void methods.  Whenever we write unit test cases for any method, we expect a return value from the method. Generally, we use assert for checking if the method returns the value that we expect it to return, but in the case of void methods, they do not return any value. So how do we check if our method is functioning properly? Let’s...

Important Linux Commands

  ls -lrt → command lists the contents of the directory with all the details, in reverse order of their modification time (older files will be displayed first) ls -lrth → This will list the contents of the current directory showing more information and sorting them so the most recently modified file will be displayed last. The h flag makes the file sizes more human friendly! chmod 755 <name> → chmod 755 sets the 755 permission for a file. 755 means full permissions for the owner and read and execute permission for others. ln -s 14.9.0-SNAPSHOT current → Create a current tag and mapped to current version. To link files in the same directory Update Any File → sed -i 's/10.46.87.148/10.46.87.115/g' journal.sch textToFind → 10.46.87.148 replaceText → 10.46.87.115 FileName → journal.sch . SED is a text stream editor used on Unix systems to edit files quickly and efficiently Untar a tar file → tar -xvzf filename.tar Rmove a folder → rm -r folderName netstat -anpe | grep ...
