> SpringBoot整合mybatis步骤

1.  创建SpringBoot工程
2.  在pom文件中导入mybatis相关的依赖

<dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>5.1.25</version>
        <scope>runtime</scope>
    </dependency>
    
    <dependency>
        <groupId>org.mybatis.spring.boot</groupId>
        <artifactId>mybatis-spring-boot-starter</artifactId>
        <version>2.0.1</version>
    </dependency>
    
    <dependency>
        <groupId>com.github.pagehelper</groupId>
        <artifactId>pagehelper</artifactId>
        <version>5.0.0</version>
    </dependency>

1.  在SpringBoot配置文件中定义数据源，并整合mybatis相关的配置

#定义数据源组件  
    spring.datasource.driver-class-name=com.mysql.jdbc.Driver
    spring.datasource.url=jdbc:mysql://localhost:3306/userdb?useUnicode=true&characterEncoding=utf-8
    spring.datasource.username=root
    spring.datasource.password=123
    
    #springboot整合mybatis的配置
    #指定mybatis的配置文件(将mybatis配置文件复到resources目录下mybatis中根据自己的需求在mybatis配置文件中添加自己的配置)
    mybatis.config-location=classpath:mybatis/mybatis-config.xml

mybatis配置文件

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
    "http://mybatis.org/dtd/mybatis-3-config.dtd">
    <configuration>
    
    	<plugins>
    		<plugin interceptor="com.github.pagehelper.PageInterceptor"></plugin>
    	</plugins>
    	</environments>-->
    
    	 
    	
    
    </configuration>

1.  记得在SpringBoot启动类上添加mapper接口扫描注解

@SpringBootApplication
    //添加扫描mybatis的dao层接口，生成实现类
    @MapperScan(value = "com.baidu.mapper")
    public class Sbdemo2Application { 
        public static void main(String[] args) { 
            SpringApplication.run(Sbdemo2Application.class, args);
        }
    }

1.  在pom.xml 中添加资源打包配置

<resources>
    			<resource>
    				<directory>src/main/java</directory>
    				<includes>
    					<include>**/*.xml</include>
    				</includes>
    			</resource>
    			<resource>
    				<directory>src/main/resources</directory>
    				<includes>
    					<include>**/*.*</include>
    				</includes>
    			</resource>
    		</resources>
