sql 映射文件 放在 代码中时需要配置
此处扫描 src/main/java 中所有xml文件发布时导入resources中。
因为用了资源配置重写了系统默认的配置，必须配置yml和properties文件
-->
<resources>

<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/*.yml</include>
<include>**/*.properties</include>
</includes>
</resource>
</resources>
</build>注意：
1. 插件中使用的 mysql-connector-java 与application.yml 中保持一致
2.configurationFile 中指定了生成器配置文件 generatorConfig.xml的位置
3.发布时为了将mapper包中sql映射文件xml 导入资源文件中，加入resources。因此导致重新了默认的资源配置，需要额外导入*.yml,*.properties
路径：
src\main\resources\generatorConfig.xml
内容：

<table tableName="%">

</table>
</context>
</generatorConfiguration>1. javaModelGenerator 实体和Example文件指定位置
2. sqlMapGenerator SQL映射文件*.Mapper.xml 所在位置
3. javaClientGenerator 接口文件所在位置
4. tableName="%" 为生成所有表
jdbcConnection driverClass ：需与application.yml中保持一致
5.1 点击
5.2 . 生成
@SpringBootApplication@MapperScan("com.zhl.springmybatis.mapper")public class SpringMybatisApplication {public static void main(String[] args) {
SpringApplication.run(SpringMybatisApplication.class, args);
}
}@Data
@ToString
public class Student {....}StudentService:
package com.zhl.springmybatis.service;
import com.zhl.springmybatis.pojo.Student;
import java.util.List;
public interface StudentService {
List<Student> getList();
}StudentServiceImpl
@Service
public class StudentServiceImpl implements StudentService {
@Resource
private StudentMapper studentMapper;
@Override
public List<Student> getList() {
StudentExample studentExample=new StudentExample();
List<Student> list= studentMapper.selectByExample(studentExample);
for (Student s:list) {
System.out.println(s);
}
return list;
}
}这里引用 Mapper接口 使用 @Resource 避免出现警告红线。
@SpringBootTest
class SpringMybatisApplicationTests {
@Resource
private StudentMapper studentMapper;
@Test
void contextLoads() {
}
@Test
public void GetList(){
StudentExample studentExample=new StudentExample();
List<Student> list= studentMapper.selectByExample(studentExample);
for (Student s:list) {
System.out.println(s);
}
}
}
