SpringBoot通过反射使用mybatis的Dao操作

需求如下：



目的要把所有的Dao和Model封装在一个反射操作的Model里统一管理，在反射过程中方法invoke需要接口的实例，我们都知道接口是不能被实例化的，而java的动态代理可以解决这一问题，有关动态代理的事情本文就不说明了，请自行百度。

代码中我是以反射操作的Model的List作为参数的：

import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
import java.util.List;
import org.apache.ibatis.session.SqlSession;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.influxdb.InfluxDBTemplate;
import org.springframework.stereotype.Component;
import org.springframework.transaction.annotation.Transactional;

import com.nbst.idevcloud.dispose.model.CacheModel;

@Component
public class TransactionUtil {

private static final Logger LOG = LoggerFactory.getLogger(TransactionUtil.class);

//自动注入SqlSession
@Autowired
private SqlSession sqlSession;

@Autowired
private InfluxDBTemplate influxDBTemplate;

@Transactional
public void mysqlInsertTransaction(List<CacheModel> list) throws InstantiationException, IllegalAccessException {
CacheModel cacheModel = new CacheModel();
Class ModelClass = null;
Class DaoClass = null;
Method m = null;
for (int i = 0; i < list.size(); i++) {
cacheModel = (CacheModel) list.get(i);
try {
//反射获取model类
ModelClass = Class.forName(cacheModel.getModelClass());
//反射获取dao类
DaoClass = Class.forName(cacheModel.getDaoClass());
//反射获取dao类中相关操作的方法
m = DaoClass.getMethod(cacheModel.getMethod(), ModelClass);
m.invoke(sqlSession.getMapper(DaoClass), cacheModel.getModelValue());
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (NoSuchMethodException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InvocationTargetException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
//实例置空回收
cacheModel = null;
ModelClass = null;
DaoClass = null;
m = null;
}
}
