想了解Spring boot + mybatis + orcale实现步骤实例代码讲解的相关内容吗,弓长张&木子李在本文为您仔细讲解Spring boot + mybatis + orcale的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:Spring,boot,mybatis,orcale,下面大家一起来学习吧。

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"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

  <relativePath/> <!-- lookup parent from repository -->
 </parent>
 <properties>
  <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

 </properties>
 <dependencies>

   <artifactId>spring-boot-starter-test</artifactId>
   <scope>test</scope>
  </dependency>
  <dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-thymeleaf</artifactId>
  </dependency>
  <!--orcale数据库依赖-->
  <dependency>
   <groupId>oracle</groupId>
   <artifactId>ojdbc7</artifactId>
   <version>1.0.0.1</version>
  </dependency>
  <!--mybatis依赖-->
  <dependency>

   <artifactId>mybatis-spring-boot-starter</artifactId>
   <version>1.1.1</version>
  </dependency>
  <dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-jdbc</artifactId>
  </dependency>
 </dependencies>
 <build>
  <plugins>
   <plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
   </plugin>
  </plugins>
 </build>
</project>

第八步:浏览器输入http://localhost:8080/person/show?name=zhang
