Spring Boot 之 Hello World 战记

1. Maven创建SpringBoot项目

2. application.properties

spring.session.store-type=none // 解决默认的30+编译错误

3. demoNative.iml (屏蔽Mongo依赖)

    <!--
    <orderEntry type="library" name="Maven: org.springframework.boot:spring-boot-starter-data-mongodb:1.5.6.RELEASE" level="project" />
    <orderEntry type="library" name="Maven: org.mongodb:mongodb-driver:3.4.2" level="project" />
    <orderEntry type="library" name="Maven: org.mongodb:bson:3.4.2" level="project" />
    <orderEntry type="library" name="Maven: org.mongodb:mongodb-driver-core:3.4.2" level="project" />
    <orderEntry type="library" name="Maven: org.springframework.data:spring-data-mongodb:1.10.6.RELEASE" level="project" />
    -->

4. pom.xml (屏蔽Mongo依赖)

		<!--
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-data-mongodb</artifactId>
		</dependency>
		-->

5. DemoApplication.java

@SpringBootApplication(exclude = {MongoAutoConfiguration.class, SecurityAutoConfiguration.class}) // 屏蔽默认Mongo设置（解决Socket链接错误） 屏蔽Tomcat用户认证（解决提示输入用户名密码）
@RestController // 使之能够路由适配
public class DemoApplication {

	@RequestMapping("/") // 默认路由为"Hello World!"
	public String hello(){
		return "Hello World!";
	}

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

　　

http://localhost:8080 默认显示 Hello World!
