Spring Boot Not Web

Create problem with Spring Boot(without Web)

Let’s make a general problem with Spring Boot
I use following

• Spring Boot(For properties and logging)
• spring-context
• spring-jdbc
• spring

Environment

• MySQL
• IntelliJ

Create Spring Boot Project with IDEA

Create project and build.gradle

mkdir SpringProgram
cd SpringProgram
mkdir -p src/main/java
mkdir -p src/main/resources
mkdir -p src/main/test
touch build.gradle

Prepare build.gradle

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath(
                'org.springframework.boot:spring-boot-gradle-plugin:1.5.2.RELEASE'
        )
    }
}

apply plugin: "java"
apply plugin: "idea"
apply plugin: 'spring-boot'


idea {
    module {
        inheritOutputDirs = false
        outputDir = file("$buildDir/classes/main/")
    }
}

jar {
    baseName = "SpringProject"
    version =  "0.0.1-SNAPSHOT"
}

repositories {
    mavenCentral()
}

dependencies {
    compile('org.springframework:spring:4.3.7.RELEASE')
    compile('org.springframework:spring-jdbc:4.3.7.RELEASE')
    compile('org.springframework:spring-context:4.3.7.RELEASE')
    compile('org.springframework.boot:spring-boot-starter')
    compile('mysql:mysql-connector-java:5.1.40')
}

Resolve Dependency

gradle idea

Download dependencies and build.

Open this folder from IntelliJ

Sample

This is Sample Application.
Start from main and try to get data from Database.

Application.java

@SpringBootApplication
@ComponentScan("com.atmarkplant.springprogram")
public class Application {

    public static void main(String[] args) {
        //ApplicationContext context = new AnnotationConfigApplicationContext(Application.class)
                ;
        ConfigurableApplicationContext context = SpringApplication.run(Application.class, args);
        MessagePrinter printer = context.getBean(MessagePrinter.class);

        DatabaseManagement databaseManagement = context.getBean(DatabaseManagement.class);
        databaseManagement.printMessage();

        printer.printMessage();
    }
}
