A brief description of the Spring-Boot microframework

What is the Spring-boot microframework?

It is well known that many *.xml initialization configuration files are required for application development using the Spring framework, and springBoot is a micro-framework designed to simplify the initial setup and development process of new Spring applications. The framework uses automatic Settings to configure, so that developers no longer need to define the template configuration, the framework can facilitate front-end developers ren Yue or testers to quickly develop or test units

2. Official Introduction to Spring

The official springboot tutorial: projects. Spring. IO/spring – the boot…

Second, rapid development of Spring-boot

1. Rely on package references

Here I personally use Spring-boot1.3.5 to build my Maven dependencies using the Maven environment:

<! -- Inherit defaults from Spring Boot -->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.3.5. RELEASE</version>
    </parent>
 
    <! -- Add typical dependencies for a web application -->
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
       
    </dependencies>
 
    <repositories>
        <repository>
            <id>spring-snapshots</id>
            <url>http://repo.spring.io/libs-snapshot</url>
        </repository>
    </repositories>
 
    <pluginRepositories>
        <pluginRepository>
            <id>spring-snapshots</id>
            <url>http://repo.spring.io/libs-snapshot</url>
        </pluginRepository>
    </pluginRepositories>
 
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
Copy the code

2. Rapid development

Simple development to publish a HelloWorld! application

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
 
@Configuration
@EnableAutoConfiguration
@Controller
public class TestController {
@RequestMapping("/hello")
@ResponseBody
public String hello(a)
{
	return "helloworld!";
	
}
	public static void main(String[] args) { SpringApplication.run(TestController.class,args); }}Copy the code

3. Release your app

As shown in the code above, the main() method is used to publish the application using built-in Tomcat by default. You can also publish the application using other built-in or external containers. Can be applied to the open open http://localhost:8080/hello released browser) :
