mybatis spring配置SqlSessionTemplate使用

1.application.xml配置

</beans>

2.MyBatisDAO ：

package com.dwr; 
import java.util.List; 
import javax.annotation.Resource; 
import org.apache.ibatis.session.RowBounds;
import org.mybatis.spring.SqlSessionTemplate;
import org.springframework.stereotype.Repository;
 
@Repository
public class MyBatisDAO{
 
 @Resource
    private SqlSessionTemplate sqlSessionTemplate;  
  
    public MyBatisDAO() {  
    }  
  
    public void setSqlSessionTemplate(SqlSessionTemplate sqlSessionTemplate) {  
        this.sqlSessionTemplate = sqlSessionTemplate;  
    }  
  
    public void delete(String statementId, Object deleteObject) {  
        try {  
            this.sqlSessionTemplate.delete(statementId, deleteObject);  
        } catch (Exception e) {  
        }  
    }  
  
    public void insert(String statementId, Object insertObject) {  
        try {  
            this.sqlSessionTemplate.insert(statementId, insertObject);  
        } catch (Exception e) {  
        }  
    }    
  
    public void update(String statementId, Object updateObject) {  
        try {  
            this.sqlSessionTemplate.update(statementId, updateObject);  
        } catch (Exception e) {  
        }  
    }    
  
    public Object getObject(String statementId, Object selectParamObject) {  
        return this.sqlSessionTemplate  
                .selectOne(statementId, selectParamObject);  
    }  
    
    @SuppressWarnings("all")
    public List queryList(String statementId, Object queryParamObject) {  
        return this.sqlSessionTemplate  
                .selectList(statementId, queryParamObject);  
    }
    @SuppressWarnings("all")
    public List queryList(String statementId, Object queryParamObject,  
            int pageNo, int pageSize) {  
        RowBounds objRowBounds;  
        int iOffset = (pageNo - 1) * pageSize;  
        objRowBounds = new RowBounds(iOffset, pageSize);  
        return this.sqlSessionTemplate.selectList(statementId,  
                queryParamObject, objRowBounds);  
    }  
}

3.mybatis配置文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
    PUBLIC "-//ibatis.apache.org//DTD Mapper 3.0//EN"
    "http://ibatis.apache.org/dtd/ibatis-3-mapper.dtd">
<mapper namespace="Test">
 <select id="queryDataCount"
  parameterType="com.mybatis.Test"
  resultType="int">
  SELECT COUNT(1) FROM INF_CONSUMER T WHERE T.UUID = #{uuid}
 </select> 
</mapper>

4.具体DAO配置

package com.dwr; 
import org.springframework.stereotype.Repository; 
import com.mybatis.Test; 
@Repository
public class TestDAO extends MyBatisDAO { 
 public int getCount(Test test) {
  return (Integer) this.getObject("Test.queryDataCount", test);
 }
}

MyBatis+SpringBoot整合 注入SqlSessionTemplate

实际开发中我们操作数据库持久化，总是需要写重复的mapper，service，xml浪费了我们大量的时间，在这里推荐大家使用SqlSessionTemplate废话不多说直接上代码

工具类接口层：

package com.miaosuan.dao;
import java.util.List;
import com.miaosuan.dao.dbenums.NameSpaceEnum;
/**
 * 数据库操作接口
 *
 * @param <T> 传入参数
 * @param <E> 返回结果
 * @author qin_wei
 */
public interface DBDao {
    <T, E> E select(NameSpaceEnum namespace, String id, T params);
    <T, E> List<E> selectList(NameSpaceEnum namespace, String id, T params);
    <T> int update(NameSpaceEnum namespace, String id, T params);
    <T> List<Long> updateList(NameSpaceEnum namespace, String id, List<T> list);
    <T> long insert(NameSpaceEnum namespace, String id, T params);
    <T> List<Long> insertList(NameSpaceEnum namespace, String id, List<T> list);
    <T> int delete(NameSpaceEnum namespace, String id, T params);
    <T> List<Long> deleteList(NameSpaceEnum namespace, String id, List<T> list);
    <T> void batchALL(NameSpaceEnum namespace, String id, List<T> params, Integer bathcount);
}

说明：NameSpaceEnum指的是你的xml的映射路径，不喜欢的可以写成自己的xml所在路径，我这边用的是枚举类

sqlid指的是你xml中方法的名字,

无论是单个操作还是批量操作，你的xml中的sql都是单个，这里的批量用的并不是mybatis的foreach操作而是通过传进来的集合批量提交事务到数据库‘'

具体使用：

接口定义：

无论批量还是单个都可以调用具体看你调用的dao里面的批量方法还是单个这个sql是如果数据库没有这条数据就添加，否则就修改，通过主键id判断，如果不喜欢这中sql可以自己用常规的update方法

所有的接口层只需要定义xml，通过dao调用就可以直接获取数据库数据。
