项目结构图

1.pom文件添加SpingBoot依赖

<?xml version="1.0" encoding="UTF-8"?>
<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">

        <relativePath/> <!-- lookup parent from repository -->
    </parent>

2.编写SB项目启动入口类Applaction.java

package com.sbm;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.tomcat.jdbc.pool.DataSource;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.annotation.MapperScan;
import org.mybatis.spring.mapper.MapperScannerConfigurer;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
/**
 * sbm
 * Created by yadong.zhang on com.sbm.application
 * User：yadong.zhang
 * Date：2016/10/20
 * Time：18:15
 */
/**
 * 1).@SpringBootApplication标注启动配置入口，run()方法会创建一个Spring应用上下文(Application Context)。
 * SpringBoot通过启动内嵌的Servlet容器（默认tomcat）用来处理Http请求。
 * 2).@RestController是特殊的Controller，他的返回值直接作为Http Response的Body部分返回给浏览器
 * 3).Spring WebMvc框架会将Servlet容器里收到的Http请求根据路径分发到对应的@Controller下进行处理。
 */
@EnableAutoConfiguration
@SpringBootApplication
@ComponentScan
//@RestController
public class Applaction {
    @RequestMapping("/")
    public String index(){
        return "Spring Boot Application...";
    }
    public static void main(String[] args) {
        SpringApplication.run(Applaction.class, args);
    }
}

3.编写测试的Controller类

package com.sbm.controller;
import com.sbm.service.IMessageService;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import javax.annotation.Resource;
import java.util.Date;
import java.util.HashMap;
import java.util.Map;
/**
 * sbm
 * Created by yadong.zhang on com.sbm.controller
 * User：yadong.zhang
 * Date：2016/10/20
 * Time：18:26
 */
@Controller
public class HelloController {
    @RequestMapping("/hello/{name}")
    public String hello(@PathVariable("name") String name, Model model) {
        model.addAttribute("name", name);
        model.addAttribute("age","25");
        model.addAttribute("sex","man");
        model.addAttribute("birth",new Date());
        return "hello";
    }
    @RequestMapping("/json")
    @ResponseBody
    public Map<String,Object> json(){
        Map<String,Object> map = new HashMap<String,Object>();
        map.put("name","Flyat");
        map.put("age","25");
        map.put("sex","man");
        return map;
    }
}

4.看效果
