Spring boot + mybatis + orcale

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"?>
