SpringBoot整合Mybatis（二）

前言：

    在我的上一篇文章中对SpringBoot整合Maybatis通过java注解的方式进行了记录，这篇文章说一下使用mybatis官方提供的Spring Boot整合包实现。

环境

  版本：SpringBoot1.5.9. RELEASE

整合工程下载

SpringBoot整合Mybatis
注：项目中除了整合Mybatis外，还整合了Redis-cluster集群、Swagger2接口说明

在application.properties中添加配置

使用逆向工程生成mybatis相关文件

    这里我使用的是从网上找的一个逆行工程代码生产的一个程序，其中就是配置generatorConfig.xml中需要逆向工程的数据库、表、并配置生成的mapper.xml和mapper的接口文件到指定包下。
工程下载地址：http://download.csdn.net/download/plei_yue/10173926
备注（需要按照自己的需求修改generatorConfig.xml文件，点击GeneratorSqlmap.java运行程序。）

配置mybatis

有两种方式进行配置：

1.在SpringBoot启动中配置: @MapperScan(“com.lpl.springboot1.dao”)

@SpringBootApplication
@MapperScan("com.lpl.springboot1.dao")
public class Springboot1Application {

    public static void main(String[] args) {
        SpringApplication.run(Springboot1Application.class, args);
    }
}

2.在接口文件中配置@Mapper

@Mapper
public interface StudentMapper {

    int insert(Student student);//增加数据

    int deleteByPrimaryKey(@Param("id")Long id);//删除数据

    int updateByPrimaryKey(Student student);//修改数据

    Student selectByPrimaryKey(Long id);//查询数据

    List selectList();//查询学生列表
}

测试

访问：http://localhost:8080/users/getStudentById.do?id=7

结果：
