Springboot项目搭建

springboot

项目构建

采用maven多模块化方式搭建项目

1.建立maven项目

​

2.导入springboot依赖

<!-- SpringBoot项目必须导入的parent依赖 -->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.1.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
 
    <!-- 定义常用的属性 -->
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
        <spring-cloud.version>Greenwich.SR3</spring-cloud.version>
    </properties>
       <!-- 声明了spring-boot的版本信息 -->
     <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <scope>import</scope>
                <type>pom</type>
            </dependency>
        </dependencies>
    </dependencyManagement>

    <dependencies>
        <!-- SpringBoot 对Web支持  SpringMVC相关功能，json转换的功能等等 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
    </dependencies>

3.编写配置文件

application.yml 或 application.properties

server:
  port: 9001
spring: #服务命令暂时没有用
  application:
    name: microservice-user

4.创建启动类

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

5.创建测试类

@RequestMapping("/user")
@RestController
public class UserController {
    /**
     *  查询所有用户
     */
    @RequestMapping(method = RequestMethod.GET)
    public List<User> findAll(){
        List<User> list = new ArrayList<>();
        list.add(new User(1,"张三",21,199.0));
        list.add(new User(2,"李四",23,199.0));
        list.add(new User(3,"王五",22,199.0));
 
        return list;
    }
}

引入打包插件

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