Spring Boot 学习

Posted 2020-10-08

pom

• 继承父pom

    <parent>
        <artifactId>spring-boot-starter-parent</artifactId>
        <groupId>org.springframework.boot</groupId>
        <version>1.5.2.RELEASE</version>
    </parent>

• 依赖

    <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>

• 插件

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

 SpringBootApplication

@SpringBootApplication
public class Main {

    public static void main(String[] args) {
        SpringApplication.run(Main.class, args);
    }
    
}

 RestController

@RestController
@RequestMapping("/demo")
public class DemoController {

    @RequestMapping("/hello")
    String home() {
        return "Hello World!";
    }
    
}

 注意

SpringBootApplication默认扫描当前包下的RestController。自定义扫描目录时使用ComponentScan扫描指定的包。
