2.目录结构:

3.配置文件:
application.properties:通用配置
spring.profiles.active=dev
spring.mvc.view.prefix=WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
application-dev.properties:开发环境配置
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://***
spring.datasource.username=***
spring.datasource.password=***
spring.datasource.max-idle=10
spring.datasource.max-wait=10000
#####配置上传下载#########
multipart.maxFileSize=50Mb
multipart.maxRequestSize=50Mb
##扫描mapper.xml
mybatis.mapper-locations=classpath:mapper/*.xml
server.port=8080
application-prod.properties:生产环境配置
默认通过application-xxx.properties识别;
springmvc中大部分配置在spring boot中都是在.properties和注解中完成
4.启动类:ImitateApplication.class
package com.imitate;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.test.context.ContextConfiguration;

@SpringBootApplication
@ContextConfiguration
@EnableAutoConfiguration
@EnableConfigurationProperties(ImitateProperties.class)
@MapperScan("com.imitate.dao")
public class ImitateApplication {

public static void main(String[] args) {
SpringApplication.run(ImitateApplication.class, args);
}

}

5.mapper.xml文件还是放在resources下的mapper文件夹下
6.dao：
package com.imitate.dao;

import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Select;

//@Mapper
public interface DealOrderDao{

// @Select("select count(*) from deal_order a where a.`status`='0' ")
int queryDealCount();

}
如果不用mybatis配置文件的话，可以直接使用@Mapper注解完成sql

7.service跟springmvc一样
8.controller:
@RequestMapping(value="index")
@Controller
public class ImitateController {

@Autowired
DealOrderServiceImpl service;

@RequestMapping(method=RequestMethod.GET)
public ModelAndView hello(){
ModelAndView mv=new ModelAndView("index");
int count = service.queryCount();
mv.addObject("count", count);
return mv;
}

}

想要跳转jsp的话就得用servlet的ModelAndView,或者直接弃用jsp选择其他视图层模版
9.jsp

放的位置根据spring.mvc.view.prefix，webapp/WEB-INF/JSP/index.jsp

10.测试类:默认与boot同包

package com.imitate.test;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.imitate.dao.DealOrderDao;

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest
public class AppTest {

@Autowired
DealOrderDao dealOrderDao;

@Test
public void testDealOrder(){
int count = dealOrderDao.queryDealCount();
System.out.println(count);
}

}

11.读取.properties配置参数
以前用@Configuration+@value("${}");
现在推荐@ConfigurationProperties(prefix="com.puruang.imitate"):
package com.imitate;

import lombok.Data;

import org.springframework.boot.context.properties.ConfigurationProperties;

@ConfigurationProperties(prefix="com.puruang.imitate")
@Data
public class ImitateProperties {

private String name;
}

12.附：spring boot 多配置优先级(由高到低):
1 命令行参数
2 来自java:comp/env的JNDI属性
3 Java系统属性（System.getProperties()）
4 操作系统环境变量
5 RandomValuePropertySource配置的random.*属性值
6 jar包外部的application-{profile}.properties或application.yml(带spring.profile)配置文件
7 jar包内部的application-{profile}.properties或application.yml(带spring.profile)配置文件
8 jar包外部的application.properties或application.yml(不带spring.profile)配置文件
9 jar包内部的application.properties或application.yml(不带spring.profile)配置文件
10 @Configuration注解类上的@PropertySource
11 通过SpringApplication.setDefaultProperties指定的默认属性
