在Mybatis中可以记录执行的SQL,在MongoTemplate中,我们也可以通过该监听器来实现。但是需要注意的是,MongoTemplate中提供的触发方法只有7个,如果执行的是aggregate,bulk等操作,无法通过监听器来记录最终执行的操作语句。 移除_class 默认情况下,在将Java对象保存至MongoDB时,MongoTemplate会在Java对象转换为Document时,会增加...
这个过程是在MongoConverter#convertId方法中完成的 java 代码解读 复制代码 defaultObjectconvertId(@NullableObject id, Class<?> targetType){if(id ==null|| ClassUtils.isAssignableValue(targetType, id)) {returnid;}// Spring推断出66aeeb73142fcf1d5591c29c能够转为ObjectId,于是targetType为ObjectIdif(Clas...
