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~~~
