接着上次的实现, 添加 mybatis 查询 orcale 数据库
第一步: 新建几个必须的包, 结果如下
第二步: 在service包下新建personService.java 根据名字查person方法接口
package com.example.first.service;
import com.example.first.entity.Person;
public interface personService {
Person queryPersonByName(String name);
}
第三步: 在serviceImpl包下新建personServiceImpl.java 实现personService.java接口
package com.example.first.serviceImpl;
import com.example.first.personDao.personMapperDao;
import com.example.first.entity.Person;
import com.example.first.service.personService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional; @Service
@Transactional
public class personServiceImpl implements personService { @Autowired
personMapperDao personMapperDao; @Override
public Person queryPersonByName(String name) {
Person person = personMapperDao.findByName(name);
return person;
}
}
第四步: personDao下新建personMapperDao.java 有一个查询person的方法
package com.example.first.personDao; import com.example.first.entity.Person;
import org.apache.ibatis.annotations.Mapper; @Mapper
public interface personMapperDao {
Person findByName(String name);
}
第五步: 在resource下新建personMapper.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.example.first.personDao.personMapperDao"> <resultMap id="findPerson" type="com.example.first.entity.Person">
<result property="name" column="name"/>
<result property="age" column="age"/>
</resultMap>
<select id="findByName" resultMap="findPerson">
select name,age from person where name = #{name}
</select>
</mapper>
第六步: 在application.properties 中添加数据源 , mapper文件路径 和实体路径
spring.jpa.database=oracle
spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
spring.datasource.url=jdbc:oracle:thin:@//192.168.3.177:1521/orcl
spring.datasource.username=liguang_dev
spring.datasource.password=123456
spring.jpa.hibernate.ddl-auto=update mybatis.mapperLocations=classpath:/mapper/*.xml
mybatis.typeAliasesPackag= com.example.first.entity spring.thymeleaf.prefix=classpath:/templates/
spring.thymeleaf.suffix=.html
spring.thymeleaf.mode = HTML5
第七步: 在pom文件中添加依赖
<?xml version="1.0" encoding="UTF-8"?>
