springboot 整合fluent mybatis的过程,看这篇够了

1.导入pom依赖

<!--        mybatis-->
        <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>
 
        <dependency>
            <groupid>org.apache.commons</groupid>
            <artifactid>commons-dbcp2</artifactid>
            <version>2.5.0</version>
        </dependency>
<!-- 引入fluent-mybatis 运行依赖包, scope为compile -->
        <dependency>
            <groupid>com.github.atool</groupid>
            <artifactid>fluent-mybatis</artifactid>
            <version>1.6.8</version>
        </dependency>
        <!-- 引入fluent-mybatis-processor, scope设置为provider 编译需要，运行时不需要 -->
        <dependency>
            <groupid>com.github.atool</groupid>
            <artifactid>fluent-mybatis-processor</artifactid>
            <version>1.6.8</version>
        </dependency>

2.配置数据库连接

spring.datasource.url= jdbc:mysql://localhost:3306/test?useunicode=true&characterencoding=utf-8&servertimezone=utc
spring.datasource.username=root
spring.datasource.password=root

3.创建数据库表

create table `student` (
  `id` bigint(20) unsigned not null auto_increment,
  `name` varchar(20) default null,
  `age` int(11) default null,
  primary key (`id`)
) engine=innodb default charset=utf8 comment='学生表';

4.创建student实体类，

        ①实体类添加 @fluentmybatis

        ②实现 ientity 接口

@fluentmybatis
@data
@noargsconstructor
public class student implements ientity {
    private long id;
    private string name;
    private integer age;
}

5.重新构建项目

构建完成后，target目录下就会新建几个文件夹

 6. 测试

@autowired
    private studentmapper studentmapper; // target目录下
    @requestmapping("insert")
    public void insert(){
        student student = new student();
        student.setname("dl");
        student.setage(25);
        studentmapper.insert(student);
    }

数据库已插入

 ************************************

如果出现mapper文件找不到路径的异常，很可能是在之前idea中将target文件隐藏了，只需

file --> setting -->  file types   将忽视的target文件删掉就可以了
