篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了JavaEE三大框架的整合相关的知识，希望对你有一定的参考价值。

JavaEE三大框架的整合

                                                                                                                              2019-05-14   14:01:39

 

 

注：应用软件为：Eclipse+MySQL；三大框架版本为：Struts2+Spring5+Hibernate5

第一步准备工作

 

三大框架所用的.jar下载，文件见如下链接：

 

https://www.cnblogs.com/MrZhangxd/p/10793454.html

 

整合目录结构：（打马赛克的地方有个人信息，望宝宝们见谅）

第二步 配置SSH三大框架

将以上下载的.jar文件复制粘贴到WebContent/WEB-INF/lib文件夹下

第三步 主要实现业务逻辑代码

注：dao.impl、service.impl包在dao、service包建完并且里面有.java文件后在建，以免发生dao、service包被dao.impl、service.impl包所覆盖。

注：dao.impl、service.impl包在dao、service包建完并且里面有.java文件后在建，以免发生dao、service包被dao.impl、service.impl包所覆盖。

主要代码如下：不在多余解释，有啥看不懂可以发我邮箱，有时间会给宝宝们解决的

第四步 主要是配置文件

web.xml

struts.xml

applicationContext.xml

hibernate.cfg.xml

db.properties

Regeister.jsp

LongForm.jsp

Welcome.jsp

ListUser.jsp

UpdataUser.jsp

Error.jsp

 

接下来一一写jsp页面

到此为止ssh三大框架整合完成

 

第六步 数据操作

 

创建数据库

Create database db_ssh;

创建tb_user表

CREATE TABLE `tb_user` (

  `id` int(11) NOT NULL AUTO_INCREMENT,

  `password` varchar(255) DEFAULT NULL,

  `username` varchar(255) DEFAULT NULL,

  `age` int(11) DEFAULT NULL,

  PRIMARY KEY (`id`)

) AUTO_INCREMENT=6 DEFAULT CHARSET=utf8;

向tb_user表中插入数据

INSERT INTO `tb_user` VALUES (‘1‘, ‘xxx‘, ‘宝宝们‘, ‘永远18岁‘);

INSERT INTO `tb_user` VALUES (‘2‘, ‘xxx‘, ‘宝宝们‘, ‘永远18岁‘);

INSERT INTO `tb_user` VALUES (‘3‘, ‘xxx‘, ‘宝宝们‘, ‘永远18岁‘);

INSERT INTO `tb_user` VALUES (‘4‘, ‘xxx‘, ‘宝宝们‘, ‘永远18岁‘);

INSERT INTO `tb_user` VALUES (‘5‘, ‘xxx‘, ‘宝宝们‘, ‘永远18岁‘);
