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：
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; /** * @author VampireAchao * @since 2023/1/5 16:34 */ @Configuration public class MpConfig { public MpConfig(MybatisPlusAutoConfiguration config, ConversionService conversionService) { final List<TableInfo> tableInfos = TableInfoHelper.getTableInfos(); Steam.of(tableInfos).parallel().forEach(tableInfo -> { final Reflector reflector = tableInfo.getReflector(); final Map<String, Invoker> setMethods = ReflectHelper.getFieldValue(reflector, "setMethods"); setMethods.computeIfPresent(tableInfo.getKeyProperty(), (k, v) -> new Invoker() { @Override public Object invoke(Object target, Object[] args) throws IllegalAccessException, InvocationTargetException { final Object convert = conversionService.convert(args[0], v.getType()); return v.invoke(target, new Object[]{convert}); } @Override public Class<?> getType() { return v.getType(); } }); }); } }
