SpringBoot------新建一个项目

1.新建一个Maven Project

2.选择项目路劲

3.选择Web App

4.添加项目名称

5.右击“Properties”-》“Java Build Path”-》“Source”，发现缺少两个路径

解决方法：现将原来两个缺少的路径删除，再重新添加，再调整下位置

6.打开pom.xml文件，添加依赖包，保存

<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/maven-v4_0_0.xsd">

  <modelVersion>4.0.0</modelVersion>

  <groupId>cn.itsource</groupId>

  <artifactId>springboot-shop</artifactId>

  <packaging>war</packaging>

  <version>0.0.1-SNAPSHOT</version>

  <name>springboot-shop Maven Webapp</name>

  <url>http://maven.apache.org</url>

  <!-- 如果添加了Parent，则dependency中可以不加入version，会自动匹配parent的版本 -->

  <parent>

      <groupId>org.springframework.boot</groupId>

      <artifactId>spring-boot-starter-parent</artifactId>

      <version>1.5.9.RELEASE</version>

  </parent>

  <properties>

      <java.version>1.8</java.version>

      <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

    <maven.compiler.encoding>UTF-8</maven.compiler.encoding>

  </properties>

  <dependencies>

    <dependency>

          <groupId>org.springframework.boot</groupId>

          <artifactId>spring-boot-starter-web</artifactId>

      </dependency>

      <dependency>

          <groupId>javax.servlet</groupId>

          <artifactId>javax.servlet-api</artifactId>

          <scope>provided</scope>

      </dependency>

      <dependency>

          <groupId>javax.servlet</groupId>

          <artifactId>jstl</artifactId>

      </dependency>

      <dependency>

          <groupId>org.springframework.boot</groupId>

          <artifactId>spring-boot-starter-tomcat</artifactId>

          <scope>provided</scope>

      </dependency>

      <dependency>

          <groupId>org.apache.tomcat.embed</groupId>

        <artifactId>tomcat-embed-jasper</artifactId>

      </dependency>

      <dependency>

          <groupId>com.alibaba</groupId>

          <artifactId>fastjson</artifactId>

          <version>1.2.15</version>

      </dependency>

  </dependencies>

  <build>

    <finalName>myshop</finalName>

    <!-- 热部署插件 -->

    <plugins>

        <plugin>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-maven-plugin</artifactId>

        </plugin>

    </plugins>

  </build>

</project>

7.编写HelloController.java

package myshop.controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RestController;

/**

 * @RestController = @Controller + @RequestBody

 *

 */

@RestController

public class HelloController {

    /**

     * 建立请求映射

     *

     */

    @RequestMapping

    public String hello() {

        return "hello";

    }

}

8.编写启动类

package myshop.controller;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication

public class App {

    public static void main(String[] args) {

        // TODO Auto-generated method stub

        SpringApplication.run(App.class, args);

    }

}

9.右键项目-》“Debug As”-》“Java Application”，启动项目

如图所示，则表示启动成功

10.打开链接：http://localhost:8080/hello

11.恭喜你，项目Spring Boot项目成功啦~~~
