2.53版代码变化不大

更新日志如下：

2.52(2.53)
Register mapper as spring bean
Generating generatedKey for number only

2.5
Update mybatis generator configuration
Auto generate <generatedKey/> tag for single primary key according to
datasource
Adapt to IntelliJ IDEA 15
Many bugs fixed

2.4
Reference sql parameter to related elements
New friendly way to show popup menu
New friendly way to choose folder when generating mapper xml
Support generating statement while existing multi mapper xml with same
namespace
Add a template for the configuration file of mybatis generator to make
it mush easier to create a new configuration file
Support smart completion for the configuration file of mybatis
generator to make it much easier to edit Run mybatis generator in
IntelliJ IDEA [Right click on a generator configuration file, then run
as 'Mybatis Generator']
Associate related elements of mybatis configuration file to make them
working better together Support template of mybatis configuration file

破解过程和前面的一样
我测试了4台电脑，3台装上能正常使用，1台不能用，原因未知(不能使用的那台使用2.531，成功)

需要修改的是2个文件
mybatis_plus.jarcomseventh7mybatisserviceJavaService.class
和
mybatis_plus.jarcomseventh7mybatisutilJavaUtils.class

安装前修改时间为2099年等很多年后的时间点，安装后选择免费试用30天，然后退出idea，把时间修改回来，这样就可以成功注册了

如果之前使用过授权服务器等激活方式，不弹出试用界面，请到C:Users计算机用户名\.IntelliJIdea15config目录下将idea15.key文件重命名为idea15.key.bak，或者尝试重装idea

初学spring mvc+mybatis，无奈网上各种资料不全，写此文以备份。

1、在idea中安装mybatis插件

插件下载地址http://download.csdn.net/detail/lanyu19950216/9220631，下载后在idea中插件页选择从磁盘安装插件，安装后重启idea即可。

2、mybatis插件的使用

这里https://www.youtube.com/watch?v=Adlp-XuuKAM这个视频录得挺不错的，可以直接看这个视频。

3、在idea中创建新的项目

最近研究RSA破解算法，找了大量资料，得到一些心得，这里记录下。
1、RSA算法有公钥和私钥，一般资料上都是数字来举例，实际看见的有字母，这里要注意下资料上的是10进制，实际是16进制。
2、公钥和私钥是一对，一个私钥对应一个公钥，用公钥可以计算出私钥，用私钥可以计算出公钥，不过用私钥计算公钥的计算量比用公钥计算私钥的计算量小。
3、公钥本身也是一对，私钥本身也是一对的，公钥(n,e)，私钥(n,d)，其中n=pq，p和q是互不相等的质数，令t=(p-1)(q-1)，有p和q了就可以计算出n，e是自己选的，一般是用的65537（16进制10001），e需要和t互质，且1<e<t，然后公式ed%t=1，这里e和t是已知的，解出一个d就可以了。
4、知道怎么用p、q生成公钥、私钥了，那么现在就知道了破解RSA算法的方法了，把公钥中的n拿来分解质因数，就可以得到p、q，然后就可以计算出私钥了。

补充：公钥和私钥区分并不明显，公钥加密用私钥解密，私钥加密的用公钥解密。

下面是我用python写的代码，测试了些简单的，可以很快计算出，代码用的python 3
