简介

  在企业级开发中、我们经常会有编写数据库表结构文档的时间付出,从业以来,待过几家企业,关于数据库表结构文档状态:要么没有、要么有、但都是手写、后期运维开发,需要手动进行维护到文档中,很是繁琐、如果忘记一次维护、就会给以后工作造成很多困扰、无形中制造了很多坑留给自己和后人,于是萌生了要自己写一个插件工具的想法,但由于自己前期在程序设计上没有很多造诣,且能力偏低,有想法并不能很好实现,随着工作阅历的增加,和知识的不断储备,终于在2020年的3月中旬开始进行编写,4月上旬完成初版,想完善差不多在开源,但由于工作太忙,业余时间不足,没有在进行完善,到了6月份由于工作原因、频繁设计和更改数据库、经常使用自己写的此插件、节省了很多时间,解决了很多问题 ,在仅有且不多的业余时间中、进行开源准备,于2020年6月22日,开源,欢迎大家使用、建议、并贡献。
  关于名字,想一个太难了,好在我这个聪明的小脑瓜灵感一现,怎么突出它的小,但重要呢?从小就学过雷锋的螺丝钉精神,摘自雷锋日记:虽然是细小的螺丝钉,是个细微的小齿轮,然而如果缺了它,那整个的机器就无法运转了,慢说是缺了它,即使是一枚小螺丝钉没拧紧,一个小齿轮略有破损,也要使机器的运转发生故障的...,感觉自己写的这个工具,很有这意味,虽然很小、但是开发中缺了它还不行,于是便起名为screw(螺丝钉)。

扩展模块

pojo生成功能

功能简介

  pojo生成功能是基于screw延伸出的扩展模块,目前处于初步开发的状态。在日常的开发中,经过需求分析、建模之后,往往会先在数据库中建表,其次在进行代码的开发。那么pojo生成功能在这个阶段就可以帮助大家节省一些重复劳动了。使用pojo生成功能可以直接根据数据库生成对应的java pojo对象。这样后续的修改,开发都会很方便。

常见问题

  • 生成后文档乱码?

    MySQL:URL加入?characterEncoding=UTF-8

  • Caused by: java.lang.NoSuchFieldError: VERSION_2_3_30?

    检查项目freemarker依赖,这是由于版本过低造成的,升级版本为2.3.30即可。

  • java.lang.AbstractMethodError: oracle.jdbc.driver.T4CConnection.getSchema()Ljava/lang/String;

    这是因为oracle驱动版本过低造成的,删除或屏蔽目前驱动版本,驱动添加升级为以下版本:

    <dependency>
       <groupId>com.oracle.ojdbc</groupId>
       <artifactId>ojdbc8</artifactId>
       <version>19.3.0.0</version>
    </dependency>
    <dependency>
       <groupId>cn.easyproject</groupId>
       <artifactId>orai18n</artifactId>
       <version>12.1.0.2.0</version>
    </dependency>
  • MySQL数据库表和列字段有说明、生成文档没有说明?

    URL链接加入useInformationSchema=true即可。

  • java.lang.AbstractMethodError: com.mysql.jdbc.JDBC4Connection.getSchema()Ljava/lang/String;

    这是因为mysql驱动版本过低造成的,升级mysql驱动版本为最新即可。

GNU LESSER GENERAL PUBLIC LICENSE Version 3, 29 June 2007 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. This version of the GNU Lesser General Public License incorporates the terms and conditions of version 3 of the GNU General Public License, supplemented by the additional permissions listed below. 0. Additional Definitions. As used herein, "this License" refers to version 3 of the GNU Lesser General Public License, and the "GNU GPL" refers to version 3 of the GNU General Public License. "The Library" refers to a covered work governed by this License, other than an Application or a Combined Work as defined below. An "Application" is any work that makes use of an interface provided by the Library, but which is not otherwise based on the Library. Defining a subclass of a class defined by the Library is deemed a mode of using an interface provided by the Library. A "Combined Work" is a work produced by combining or linking an Application with the Library. The particular version of the Library with which the Combined Work was made is also called the "Linked Version". The "Minimal Corresponding Source" for a Combined Work means the Corresponding Source for the Combined Work, excluding any source code for portions of the Combined Work that, considered in isolation, are based on the Application, and not on the Linked Version. The "Corresponding Application Code" for a Combined Work means the object code and/or source code for the Application, including any data and utility programs needed for reproducing the Combined Work from the Application, but excluding the System Libraries of the Combined Work. 1. Exception to Section 3 of the GNU GPL. You may convey a covered work under sections 3 and 4 of this License without being bound by section 3 of the GNU GPL. 2. Conveying Modified Versions. If you modify a copy of the Library, and, in your modifications, a facility refers to a function or data to be supplied by an Application that uses the facility (other than as an argument passed when the facility is invoked), then you may convey a copy of the modified version: a) under this License, provided that you make a good faith effort to ensure that, in the event an Application does not supply the function or data, the facility still operates, and performs whatever part of its purpose remains meaningful, or b) under the GNU GPL, with none of the additional permissions of this License applicable to that copy. 3. Object Code Incorporating Material from Library Header Files. The object code form of an Application may incorporate material from a header file that is part of the Library. You may convey such object code under terms of your choice, provided that, if the incorporated material is not limited to numerical parameters, data structure layouts and accessors, or small macros, inline functions and templates (ten or fewer lines in length), you do both of the following: a) Give prominent notice with each copy of the object code that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the object code with a copy of the GNU GPL and this license document. 4. Combined Works. You may convey a Combined Work under terms of your choice that, taken together, effectively do not restrict modification of the portions of the Library contained in the Combined Work and reverse engineering for debugging such modifications, if you also do each of the following: a) Give prominent notice with each copy of the Combined Work that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the Combined Work with a copy of the GNU GPL and this license document. c) For a Combined Work that displays copyright notices during execution, include the copyright notice for the Library among these notices, as well as a reference directing the user to the copies of the GNU GPL and this license document. d) Do one of the following: 0) Convey the Minimal Corresponding Source under the terms of this License, and the Corresponding Application Code in a form suitable for, and under terms that permit, the user to recombine or relink the Application with a modified version of the Linked Version to produce a modified Combined Work, in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source. 1) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (a) uses at run time a copy of the Library already present on the user's computer system, and (b) will operate properly with a modified version of the Library that is interface-compatible with the Linked Version. e) Provide Installation Information, but only if you would otherwise be required to provide such information under section 6 of the GNU GPL, and only to the extent that such information is necessary to install and execute a modified version of the Combined Work produced by recombining or relinking the Application with a modified version of the Linked Version. (If you use option 4d0, the Installation Information must accompany the Minimal Corresponding Source and Corresponding Application Code. If you use option 4d1, you must provide the Installation Information in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source.) 5. Combined Libraries. You may place library facilities that are a work based on the Library side by side in a single library together with other library facilities that are not Applications and are not covered by this License, and convey such a combined library under terms of your choice, if you do both of the following: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities, conveyed under the terms of this License. b) Give prominent notice with the combined library that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 6. Revised Versions of the GNU Lesser General Public License. The Free Software Foundation may publish revised and/or new versions of the GNU Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library as you received it specifies that a certain numbered version of the GNU Lesser General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that published version or of any later version published by the Free Software Foundation. If the Library as you received it does not specify a version number of the GNU Lesser General Public License, you may choose any version of the GNU Lesser General Public License ever published by the Free Software Foundation. If the Library as you received it specifies that a proxy can decide whether future versions of the GNU Lesser General Public License shall apply, that proxy's public statement of acceptance of any version is permanent authorization for you to choose that version for the Library.
