2、数据库配置

application.yml

server:port: 8888spring:datasource:driver-class-name: oracle.jdbc.driver.OracleDriverurl: jdbc:oracle:thin:@172.22.177.37:11521/smicpusername: MCSSDpassword: McSSd3P@x6Wp_k

application.properties

#端口号
server.port=8080
#druid数据库连接池
type=com.alibaba.druid.pool.DruidDataSource
#清除缓存
spring.thymeleaf.cache=false
#配置mapper
mybatis.mapper-locations=classpath:mapper/*.xml

3、mapper文件

package com.example.dyc.myofbatis;import org.apache.ibatis.annotations.Mapper;@Mapper
public interface TProdTaskMapper {ProdTask queryById(String prodTaskId);ProdTask queryByTaskNo(String taskNo);
}

4、mapper.xml

package com.example.dyc.myofbatis;import org.apache.ibatis.annotations.Mapper;@Mapper
public interface TProdTaskMapper {ProdTask queryById(String prodTaskId);ProdTask queryByTaskNo(String taskNo);
}

5、单元测试代码

导航栏右键Test生成

package com.example.dyc.myofbatis;import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;import javax.sql.DataSource;import java.sql.Connection;
import java.sql.SQLException;@SpringBootTest
class TProdTaskMapperTest {@AutowiredDataSource dataSource;//测试连接数据库是否成功@Testvoid loadToBeRecovered() throws SQLException {System.out.println(dataSource.getClass());Connection connection = dataSource.getConnection();System.out.println(connection);connection.close();}//mapper测试@AutowiredTProdTaskMapper tProdTaskMapper;@Testpublic void toTest(){ProdTask userLogins = tProdTaskMapper.queryById("77777777");System.out.println(userLogins == null);}
}
