升级mp新版本后,service里removeByIds主键类型不一致报错

先谋后事者逸，先事后图者失。——陈子昂

场景：

主键类型是Integer，使用service中removeByIds，传入List<String>报错

MP用的mybatis的反射，只需要在表信息初始化后，获取反射的缓存map，往里面放入我们自定义的转换操作即可

代码如下：

代码语言：javascript复制

import com.baomidou.mybatisplus.autoconfigure.MybatisPlusAutoConfiguration;
import com.baomidou.mybatisplus.core.metadata.TableInfo;
import com.baomidou.mybatisplus.core.metadata.TableInfoHelper;
import io.github.vampireachao.stream.core.reflect.ReflectHelper;
import io.github.vampireachao.stream.core.stream.Steam;
import org.apache.ibatis.reflection.Reflector;
import org.apache.ibatis.reflection.invoker.Invoker;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.convert.ConversionService;

import java.lang.reflect.InvocationTargetException;
import java.util.List;
import java.util.Map;

                @Override

}
