使用eclipse搭建springboot项目

1.jar包的依赖

 <modelVersion>4.0.0</modelVersion>
  <!-- springboot 的父级依赖 -->
  <parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.9.RELEASE</version>
</parent> 
  <groupId>com.zy.springboot</groupId>
  <artifactId>zy-springboot</artifactId>
  <version>0.0.1-SNAPSHOT</version>

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

<build>
<plugins>

<!-- springboot 的编译插件 -->
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.8</source>
<target>1.8</target>
<encoding>UTF-8</encoding>
</configuration>
</plugin>
</plugins>
</build>

2.配置类

package com.zy.springboot;


import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class HelloApplication {
public static void main(String[] args) {
SpringApplication.run(HelloApplication.class, args);
}
}

3.控制类的编写

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class HelloController {
@RequestMapping("/")
@ResponseBody
public String showHello(){
return "hello world";
}
}

注意：如果pom.xml文件报错  最好清空本地仓库
