mybatis独立使用，注解sql

平时都是集成在框架里使用的，单元测试的时候需要从文件维护些数据到数据库，就写了下独立使用的代码

MybatisTest.java

package com.seer.mybatis;

import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
import org.junit.Test;

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;

public class MybatisTest {
    @Test
    public void run() throws IOException {
        InputStream inputStream = new FileInputStream(new File("D:\\Code\\oilCard\\src\\test\\java\\com\\sdgs\\mob\\mybatis\\mybatis-config.xml"));

        SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream);
        SqlSession sqlSession = sqlSessionFactory.openSession();

        Mapper mapper = sqlSession.getMapper(Mapper.class);

        int count = mapper.test();
        System.out.println(count);
    }
}

mybatis-config.xml

Mapper.java

package com.seer.mybatis;

import org.apache.ibatis.annotations.Select;

interface Mapper {
    // 注解sql，复杂的实现百度下
    @Select("select count(1) from sys_province")
    int test();
}
