springboot 整合 Mybatis mysql

1.加入mybatis需要依赖

<!--mybatis依赖-->
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>1.3.1</version>
        </dependency>

        <!--mysql依赖-->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
        </dependency>

<!--build需要修改，指定mapper文件位置-->
<build>
		<resources>
			<resource>
				<directory>src/main/java</directory>
				<includes>
					<include>**/*. </include>
				</includes>
			</resource>
		</resources>
	</build>

2.添加mysql配置

#mysql 配置
spring.datasource.url= jdbc:mysql://localhost:3306/hz_subway?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=root
        
#mybatis配置
mybatis.mapper-locations=com/seage/dao/*. 
mybatis.type-aliases-package=com.seage.entity

3.修改启动类，扫描mapper配置文件

4.简单controller（service dao层省略）

package com.test.controller;

import com.test.entity.User;
import com.test.service.TestService;
import org.spring work.beans.factory.annotation.Autowired;
import org.spring work.stereotype.Controller;
import org.spring work.web.bind.annotation.RequestMapping;
import org.spring work.web.bind.annotation.ResponseBody;

/**
 * @author gdl
 * @date 2018/12/18 17:04
 */
@RequestMapping(\"test\")
@Controller
public class TestController {
    @Autowired
    TestService testService;

    @RequestMapping(\"index\")
    public String index(){
        return \"index\";
    }


    @RequestMapping(\"/getUser\")
    @ResponseBody
    public User getUser(){
        return  testService.getUsers();
    }
}

5.浏览器访问，访问成功
