Spring Boot 之 Hello World 戰記

1. Maven建立SpringBoot項目

2. application.properties

spring.session.store-type=none // 解決默認的30+編譯錯誤

3. demoNative.iml (屏蔽Mongo依賴)

 

    <!--
    <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依賴)

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

 

5. DemoApplication.java

@SpringBootApplication(exclude = {MongoAutoConfiguration.class, SecurityAutoConfiguration.class}) // 屏蔽默認Mongo設置（解決Socket連接錯誤） 屏蔽Tomcat用戶認證（解決提示輸入用戶名密碼）
@RestController // 使之可以路由適配
public class DemoApplication {

	@RequestMapping("/") // 默認路由爲"Hello World!"
	public String hello(){
		return "Hello World!";
	}

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

　　

http://localhost:8080 默認顯示 Hello World!
