Springboot project deployment method

1 Introduction

Springboot is equivalent to a practical tool framework. It integrates the three major frameworks of ssm and simplifies the development steps, eliminating the cumbersome environment setup and various spring configurations in ssm. In short , which is a very practical framework.

2 Getting Started

2.1 Import dependencies

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.9.RELEASE</version>
</parent>
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies>

2.2 Write the main program class

/**
 * @SpringBootApplication来标注一个主程序类
 * 说明这是一个Springboot应用
 */
@SpringBootApplication
public class HelloWorldMainApplication {
    public static void main(String[] args) {
        // 让Springboot运行起来
        SpringApplication.run(HelloWorldMainApplication.class,args);
    }
}

2.3 Write the controller layer

@Controller
public class HelloController {

    @RequestMapping("/hello")
    @ResponseBody
    public String hello() {
        return "hello";
    }
}

2.4 Run the main program Program

After the main program is started, enter http://localhost:8080/hello

2.5 Deployment project

Add a jar package plug-in to pom.xml, and then package it in the maven lifecycle. Then there will be a jar file in the target directory, copy it to the folder, and then use java -java xxx in the command window. The jar is deployed successfully.

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>
