spring boot整合mybatis框架

spring boot框架

mybatis框架

intellij idea软件

推荐使用intellij idea作为开发工具，使用intellij idea创建spring boot框架，如下图所示，添加maven依赖，代码如下                                             org.mybatis.spring.boot                            mybatis-spring-boot-starter                            1.3.2                                                                    mysql                            mysql-connector-java                            runtime                  

创建一个TestMapper.java文件，代码如下/** * Created by zuli on 2018/10/10. */public interface TestMapper {      int test(); }

在resources目录下创建TestMapper.xml文件，代码如下            SELECT 1 FROM DUAL   

添加@MapperScan()注解，配置basePackages属性，代码如下@SpringBootApplication@MapperScan(basePackages = 'com.zuli.mapper')public class SpringBootMybatisApplication {          public static void main(String[] args) {                   ConfigurableApplicationContext context =                                     SpringApplication.run(SpringBootMybatisApplication.class, args);                   TestMapper testMapper = context.getBean(TestMapper.class);                   System.out.println(testMapper.test());         }}

修改application.properties配置文件，配置数据源，mapper xml文件路径等代码如下spring.datasource.url=jdbc:mysql://localhost/testspring.datasource.username=rootspring.datasource.password=123456spring.datasource.driver-class-name=com.mysql.jdbc.Driver mybatis.mapper-locations=classpath:*Mapper.xml

启动应用程序，调用TestMapper的test()方法，打印日志，如下图所示

整体demo的项目结构如下图所示

希望对你有所帮助
