Spring Boot開發(一)-一個簡單的Spring Boot工程

0.開發前的準備

• Spring Boot主頁:http://projects.spring.io/spring-boot/

• Gradle使用

1.簡單的入門級的例子

• Gradle配置

group 'org.ceecode'
version '1.0-SNAPSHOT'

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        //Spring Boot
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.3.5.RELEASE")
    }
}

apply plugin: 'java'
apply plugin: 'spring-boot'

sourceCompatibility = 1.7

repositories {
    mavenCentral()
}

dependencies {
    testCompile("org.springframework.boot:spring-boot-starter-test")

    compile("org.springframework.boot:spring-boot-starter-web")
}

• 核心代碼-Controller

@Controller
@EnableAutoConfiguration
@RequestMapping("/")
public class TestApiController {

    @RequestMapping("test")
    @ResponseBody
    public String test() {
        return "OK";
    }

}

• 核心代碼-入口

@SpringBootApplication
public class Application {

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

}

2.運行例子

    例子的運行很簡單,直接執行Main方法便可.執行後的輸入日誌:
