问题 I want to set db2 encryption password command when spring boot starts a connection with my db2. Basically some of the columns in my table are encrypted. I tried hibernate mapper @ColumnTransformer(read="decrypt_char(COLUMN_NAME,'password')",write="encrypt(?,'password')"). That does not work. After some look around I found that I have to set the encryption password with the following command when the database connection is established from spring boot application properties file. SET

Spring to Oracle UTF-8 character truncation

由 倖福魔咒の 提交于 2021-02-11 14:14:07
问题 I have an issue with invalid characters appearing in an Oracle database. The "¿" or upside-down question mark. I know its caused by UTF8 encoding's being put into the encoding of the Oracle database. Examples of characters I am expecting are ' – ' which looks like a normal hyphen but isnt, and ' ’ ' which should be a normal single quote. Input: "2020-08-31 – 2020-12-31" - looks like normal hyphen but not Output: "2020-08-31 ¿ 2020-12-31" I know the primary source of the characters are copy

问题 in our Spring application we have a table that contains a lot of "Payment" record. Now we need a query that pages the results sorted from the one with the largest total to the smallest, we are facing an error because sometimes the same record is contained in two successive pages.

Java工程师必备书单

由 会有一股神秘感。 提交于 2021-02-11 13:54:45
本文出自我的公众号：程序员江湖。 江湖路险，你我同行。 Java开发工程师一般负责后端开发，当然也有专门做Java Web的工程师，但是随着前后端的分离，越来越多的Java工程师需要往大后端方向发展。 今天我们就来介绍一下Java后端开发者的书单。 首先要感谢一下江南白衣大大的后端书架，让我在初学阶段读到了很多好书，直到现在都印象深刻。 我在两年的学习历程中看了很多的书，其中不乏XXX入门到精通，XXX王者归来，XXX指南什么的。 虽然这类书确实毛病很多，但是作为非科班的我来说，当时还是看的津津有味。直到后来我看到一些优秀的书籍，以及白衣哥的书架，我才逐渐认识到看一些精品书籍的好处。 所以我们今天就从这些精品书籍中挑选一些优秀书籍来推荐给大家，当然其中有一些书我自己也没有时间看完。 接下来我们按照后端技术栈各个部分的内容来推荐书籍。 网络 1 TCP/IP卷一 这本其实我刚开始没看太懂，可能是当时太水的原因，但是一般是大牛力荐的书。 2 计算机网络：自顶向下 这本从应用层讲到物理层，感觉这种方式学起来更轻松，我比较推荐小白看这本。 3 图解HTTP和图解TCP/IP 相较于前两本大厚书，这两本书更加亲民，小白可以买来看看，还是很适合入门的。 4 计算机网络 没错，就是这本教材，作为非科班选手自己看这本书，那叫一个欲仙欲死啊，看完就忘记了。 操作系统 1 深入理解计算机系统
