## 1、建立项目 ##

建议使用spring-tool-suite来建立编辑springboot项目，该版本的Eclipse比普通版本的Eclipse添加了对springboot的插件支持。  
创建本地maven项目，并编辑pom.xml文件，添加如下内容

<parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>1.4.7.RELEASE</version>
            <relativePath />
        </parent>
    
        <properties>
            <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
            <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
            <java.version>1.8</java.version>
        </properties>
    
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-devtools</artifactId>
                <scope>runtime</scope>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-test</artifactId>
                <scope>test</scope>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-configuration-processor</artifactId>
                <optional>true</optional>
            </dependency>
        </dependencies>
    
        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>
            </plugins>
        </build>

## 2、创建springboot启动入口 ##

package com.wxtx;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    /** * springboot默认值扫描启动入口所在的包及其子包，可用过scanBasePackages参数指定扫描的包路径 */
    @SpringBootApplication(scanBasePackages="com")
    public class TXSpringBootApplication { 
        public static void main(String[] args) {
            SpringApplication.run(TXSpringBootApplication.class, args);
        }
    }

## 3、创建Control控制器 ##

package com.wxtx.action;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.ResponseBody;
    
    @Controller
    public class TestAction { 
    
        @ResponseBody
        @RequestMapping("/index")
        public String index() {
            return "hello world";
        }
    }

## 4、启动项目 ##

java运行TXSpringBootApplication类，打开浏览器访问[http://127.0.0.1:8080/index][http_127.0.0.1_8080_index]即可。

注：springboot内置了tomcat，所以springboot web项目启动时，不需要使用tomcat server来启动，直接java application运行即可。

[http_127.0.0.1_8080_index]: http://127.0.0.1:8080/index
