SpringBoot+Maven项目实战（2）：集成SpringBoot

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"

2.编写启动类Applaction

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.编写控制类Controller

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.测试页面访问看效果
