1.1. 设置mapper 1

1.2. 、配置mybatis MybatisConfig 2

1. 1. 设置mapper

package springbootMybatis;

 

 

 

import java.util.List;

import java.util.Map;

 

import org.apache.ibatis.annotations.Delete;

import org.apache.ibatis.annotations.Insert;

import org.apache.ibatis.annotations.Mapper;

import org.apache.ibatis.annotations.Param;

import org.apache.ibatis.annotations.Select;

import org.apache.ibatis.annotations.Update;

import org.mybatis.spring.SqlSessionTemplate;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.jdbc.core.JdbcTemplate;

import org.springframework.stereotype.Component;

 

@Mapper

@Component

//iocSpring5demo.MybatisMapperCls

public interface MybatisMapperCls {

 

 

//@Autowired

//public SqlSessionTemplate sqlSessionTemplate1;

    

    /*

     * 这是基于注解的映射方式，实现对数据的增删改查，将sql语句直接写在注解的括号中

     * 这是一个接口，其不需要类去实现它

     * 下边分别是插入，删除，修改，查询一个记录，查询所有的记录

     * */

    

 

    

    @Select("${sql_intag}")

    public List<Map>   query(@Param("sql_intag") String sql);

    

 

    

}

1. 1. 、配置mybatis MybatisConfig 

首先需要配置数据源，本例使用c3p0

 

@Data

@EnableAutoConfiguration

public class MybatisConfig {

    @Autowired

    private ComboPooledDataSource dataSource;

---------------------

 

 

 

package springbootMybatis;

 

import javax.sql.DataSource;

 

import org.apache.ibatis.session.SqlSessionFactory;

import org.mybatis.spring.SqlSessionFactoryBean;

import org.mybatis.spring.SqlSessionTemplate;

import org.mybatis.spring.annotation.MapperScan;

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

import org.springframework.core.io.support.PathMatchingResourcePatternResolver;

import org.springframework.core.io.support.ResourcePatternResolver;

import org.springframework.jdbc.datasource.DataSourceTransactionManager;

 */

@Configuration

//@//Import(DruidDataSourceConfiguraiton.class)

//@MapperScan(basePackages ="springMybatis")

@EnableAutoConfiguration

public class MyBatisConfiguartion {

   

@Bean

public DataSource dataSource() {

AtiDateSource instance = new AtiDateSource();

return instance;

// configure and return the necessary JDBC DataSource

}

 

 

    @Bean

    public SqlSessionFactory getSqlSessionFactory(){

        try {

            SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();

            sqlSessionFactoryBean.setDataSource(dataSource());

            return sqlSessionFactoryBean.getObject();

        }catch (Exception e){

            e.printStackTrace();

            return null;

        }

    }

 

    /**

     *

     * @param sqlSessionFactory

     * @return

     */

    @Bean

    public SqlSessionTemplate sqlSessionTemplate(SqlSessionFactory sqlSessionFactory){

        return new SqlSessionTemplate(sqlSessionFactory);

    }

 

 

 

//    @Bean

//     public DataSource dataSource() {

//         BasicDataSource dataSource = new BasicDataSource();

//

//         dataSource.setDriverClassName("com.mysql.jdbc.Driver");

//         dataSource.setUrl("jdbc:mysql://localhost:3306/mb?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8");

//         dataSource.setUsername("");   // 这里填写数据库用户名

//         dataSource.setPassword("");   // 这里填写数据库密码

//

//         return dataSource;

//     }

//

   

 

 

//     @Bean

//     public SqlSessionFactoryBean sqlSessionFactoryBean() throws Exception {

//         SqlSessionFactoryBean sessionFactory = new SqlSessionFactoryBean();

//         sessionFactory.setDataSource(dataSource());

//    //     sessionFactory.setTypeAliasesPackage("me.firstsnow.model");

//         return sessionFactory;

//     }

//

 

/*

 @Bean(name = "sqlSessionFactory")

 public SqlSessionFactory sqlSessionFactoryBean(DataSource dataSource){

 

  

*/

 

}

1. 1.  Cotrol 

 

 

import java.util.List;

import java.util.Map;

 

import javax.servlet.http.Cookie;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpSession;

 

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RestController;

 

import com.alibaba.fastjson.JSON;

 

@RestController  

@EnableAutoConfiguration  

public class Cotrol {  

 

 

@Autowired

MybatisMapperCls MybatisMapperCls1;

      

    @RequestMapping("/")  

    public  String home(HttpServletRequest req) {  

    

     List<Map> message = MybatisMapperCls1.query("select * from user_tab");

 

     // userService.addUser("user2");

     // 输出结果

     System.out.println(  JSON.toJSONString(message));

        return "Hello World 22!";  

    }  

    

}
