ssh项目开发具体过程

在eclipse中新建一个web项目，File ---> New ---> Dynamic Web project；
往新建好的web项目中导入jar包，jar包的网址如下：https://i-beta.cnblogs.com/files，导入的位置为：web项目名 ---> WebContent ---> WEB-INF ---> lib

在web.xml中进行配置，

 1 <welcome-file-list>
 2     <welcome-file>index.html</welcome-file>
 3     <welcome-file>index.htm</welcome-file>
 4     <welcome-file>index.jsp</welcome-file>
 5     <welcome-file>default.html</welcome-file>
 6     <welcome-file>default.htm</welcome-file>
 7     <welcome-file>default.jsp</welcome-file>
 8   </welcome-file-list>

35   <listener>
36       <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
37   </listener>

在src中新建包、类等

.，以此为参考。!!!注意：User.hbm.xml，代码如下：

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <!DOCTYPE hibernate-mapping PUBLIC 
 3     "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
 4     "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
 5     
 6 <hibernate-mapping>
 7     <class name="cn.jin.entity.User" table="t_user">
 8          <id name="lid" column="lid">
 9              <generator class="native"></generator>    
10          </id>
11          <property name="lusername" column="lusername"></property>
12          <property name="lpassword" column="lpassword"></property>
13          <property name="lrepassword" column="lrepassword"></property>
14          <property name="ltel" column="ltel"></property>
15          <property name="laddress" column="laddress"></property>
16      </class>
17 </hibernate-mapping>

class的name属性为实体类的位置（包名），name属性为数据库表中的列名

在src目录下新建bean.xml，与数据库进行连接，代码如下：

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"

result中的name值为action中的方法返回的值，要注意package中的

<package name="demo" extends="struts-default" namespace="/">

extends和namespace的设置

在src目录下新建user.xml，代码如下：

 2 <beans xmlns="http://www.springframework.org/schema/beans"
 3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

接着可以在上述的包类中写代码完成所需要的功能，ssh环境搭建过程应该也就这些部分了，多加练习熟练即可。
