SpringBoot学习——SpringBoot入门HelloWorld

创建maven项目

勾选箭头处，创建一个简单的项目

填写groupId和artifactId，点击确定

配置pom.xml

官方网址有相关配置，本文采用1.5.1版本的，完整pom
注意，如果要打成可执行jar包，要指定jar包的主函数

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>HelloConsumer</groupId>
    <artifactId>HelloConsumer</artifactId>
    <version>0.0.1-SNAPSHOT</version>

    <!-- 引用依赖的父包 -->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.1.RELEASE</version>
    </parent>


    <!--maven的插件 -->
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <!-- 打成jar包后所执行的主函数 -->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-jar-plugin</artifactId>
                <configuration>
                    <archive>
                        <manifest>
                            <addClasspath>true</addClasspath>
                            <mainClass>com.pzr.consumer.test.OfficialDemo</mainClass>
                        </manifest>
                    </archive>
                </configuration>
            </plugin>
        </plugins>
    </build>

    <!-- 依赖包 -->
    <dependencies>
        <!-- spring boot需要的包 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
    </dependencies>

</project>

编写测试java类

package com.pzr.consumer.test;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

/**
 * 官方例子
 * @author pzr
 *
 */
@Controller
@EnableAutoConfiguration
public class OfficialDemo {
    @RequestMapping("/test")
    @ResponseBody
    String home() {
        return "Hello World!";
    }

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