IDEA+Hibernate+Struts2

笔者能力有限，只能用老版Hibernate和老版Struts2.

我们在IDEA中选择Struts2中的2.3版本我是直接下了jar包加入进去的，还有自动下载Hibernate3.6中的。之后进行配置。

之后再加入connector我用的是Mysql5.7版本所以用了对应的connector。

之后选择左下角的persistence，右键下面的一个文件之后generate Mapping。

之后选择链接服务器记得?useSSL=false。之后配置一下hibernate.cfg.xml中的文件,其中username和password和前面四个是自己设置的。

还要选择mapping的class和resource

update -->
之后把jstl中的jar包加入到tomcat文件夹中。这样就不用每次配置了。

之后在preference中搜索dtds

```cpp

http://java.sun.com/jsp/jstl/core

url填写这个之后再搜索你下载好的jstl中的c.tld文件慢慢找就在里面
