3.0.5版本
通过springboottest测试serivceImpl的方法：public boolean saveBatch(Collection entityList, int batchSize)
1、定义业务的UserServiceImpl
public class UserServiceImpl extends BaseServiceImpl implements UserService {
}
2、BaseServiceImpl的实现方式
public class BaseServiceImpl extends ServiceImpl, T> implements BaseService{
2、测试
@Test
public void saveBatchTest() {
List listUser = new ArrayList();
UserDO u1 = new UserDO();
u1.setName("l5");
u1.setAge(13);
u1.setCreateTime(LocalDateTime.now());
u1.setEnable(1);
u1.setPassword("123456");
listUser.add(u1);
UserDO u2 = new UserDO();
u2.setName("l6");
u2.setAge(14);
u2.setCreateTime(LocalDateTime.now());
u2.setEnable(0);
u2.setPassword("654321");
listUser.add(u2);
boolean result = userService.saveBatch(listUser, 2);
System.out.println("saveBatchTest result:" + result);
Assert.assertEquals(true, result);
}
报错信息：

不知道是不是多重继承的问题
Comment From: miemieYaho
那就自行解决
Comment From: daize1994
怎么解决的？我也遇到了这个报错，但是没有多重继承
Comment From: jackwei
/*
*
* 获取TableInfo
*
*
* @param clazz 对象类
* @return TableInfo 对象表信息
/
public static TableInfo table(Class<?> clazz) {
TableInfo tableInfo = TableInfoHelper.getTableInfo(clazz);
if (null == tableInfo) {
throw new MybatisPlusException("Error: Cannot execute table Method, ClassGenricType not found .");
}
return tableInfo;
}
好吧,我也遇到这个问题了,看来还是没人解决啊

使用saveBatch，且没有多重继承，同样遇到了此问题，暂时无法解决
Comment From: liu-xinhui
com.baomidou.mybatisplus.core.exceptions.MybatisPlusException: Error: Cannot execute table Method, ClassGenricType not found
如果是多重继承导致的此错误，可以在覆写ServiceImpl中的currentModelClass方法
spring方式
/**
* 覆写mybatis-plus获取泛型class方式，防止多重继承时无法获取class
*/
@SuppressWarnings("all")
@Override
protected Class<T> currentModelClass() {
return (Class<T>) GenericTypeResolver.resolveTypeArgument(getClass(), BaseService.class);
}
或者java方式
@SuppressWarnings("all")
@Override
protected Class<T> currentModelClass() {
ParameterizedType genType = (ParameterizedType) getClass().getGenericSuperclass();
Type type = genType.getActualTypeArguments()[0];
return (Class<T>) type;
}

可以的
