我的SSH项目之旅(1.基本配置)

此项目采用spring+hibernate+struts
数据库是mysql     连接方式采用Connection pool


我截取了几个重要步骤的图
首先配置好DB Driver   数据库连接地址：jdbc:mysql://localhost:3306/myssh

然后依次加入spring hibernate struts的支持
注意一下数据源的的填写
采用 JNDI
DataSource: java:comp/env/jdbc/myssh


右键项目属性 加入还没加进来的JAR包

版本是eclipse3.2.2+myeclipse5.1.1 这个版本会出现这个问题



SSH主要是配置文件比较复杂 不过都有一个通用的模式，很多东西都是固定不变的，除了eclipse帮我们自动生成一些，其余只要注意一定的写法就可行
一开始把几个重要的配置文件写好


applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"> <beans> <bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean"> <property name="jndiName"> <value>java:comp/env/jdbc/myssh</value> </property> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource"> <ref bean="dataSource" /> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect"> org.hibernate.dialect.MySQLDialect </prop> <!-- 表示允许自动提交 --> <prop key="hibernate.connection.autocommit">true</prop> <!-- 显示sql语句 --> <prop key="hibernate.show_sql">true</prop> </props> </property> </bean> 加入hibernate模板支持 <bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate"> <property name="sessionFactory"> <ref bean="sessionFactory"/></property> </bean> </beans>

 
Web.xml

<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <context-param> <param-name>contextConfigLocation</param-name> <param-value> /WEB-INF/classes/applicationContext.xml </param-value> </context-param> <servlet> <servlet-name>context</servlet-name> <servlet-class> org.springframework.web.context.ContextLoaderServlet </servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet> <servlet-name>action</servlet-name> <servlet-class> org.apache.struts.action.ActionServlet </servlet-class> <init-param> <param-name>config</param-name> <param-value>/WEB-INF/struts-config.xml</param-value> </init-param> <init-param> <param-name>debug</param-name> <param-value>3</param-value> </init-param> <init-param> <param-name>detail</param-name> <param-value>3</param-value> </init-param> <load-on-startup>0</load-on-startup> </servlet> <servlet-mapping> <servlet-name>action</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> </web-app>

 

在添加struts插件支持



ContextLoaderPlugIn



ContextConfigLocation


Struts-config.xml

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd"> <struts-config> <data-sources /> <form-beans /> <global-exceptions /> <global-forwards /> <action-mappings /> <controller processorClass="org.springframework.web.struts.DelegatingRequestProcessor"> </controller> <message-resources parameter="dj.fantlam.myssh.struts.ApplicationResources" /> 和spring进行整合，这是struts添加外插件的方法 <plug-in className="org.springframework.web.struts.ContextLoaderPlugIn"> <set-property property="contextConfigLocation" value="/WEB-INF/classes/applicationContext.xml" /> </plug-in> </struts-config>

 

 

编写过滤器进行乱码处理

EncodingFilter.java

package dj.fantlam.myssh.filter; import java.io.IOException; import javax.servlet.Filter; import javax.servlet.FilterChain; import javax.servlet.FilterConfig; import javax.servlet.ServletException; import javax.servlet.ServletRequest; import javax.servlet.ServletResponse; public class EncodingFilter implements Filter { private String charset = null; public void destroy() { // TODO Auto-generated method stub } public void doFilter(ServletRequest arg0, ServletResponse arg1, FilterChain arg2) throws IOException, ServletException { // TODO Auto-generated method stub arg0.setCharacterEncoding(this.charset); arg2.doFilter(arg0, arg1); } public void init(FilterConfig arg0) throws ServletException { // TODO Auto-generated method stub this.charset=arg0.getInitParameter("charset"); } }

 

Web.xml

<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <context-param> <param-name>contextConfigLocation</param-name> <param-value> /WEB-INF/classes/applicationContext.xml </param-value> </context-param> 这个是最经典的字符过滤方法了 <filter> <filter-name>encoding</filter-name> <filter-class> dj.fantlam.myssh.filter.EncodingFilter </filter-class> <init-param> <param-name>charset</param-name> <param-value>gbk</param-value> </init-param> </filter> <filter-mapping> <filter-name>encoding</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <servlet> <servlet-name>context</servlet-name> <servlet-class> org.springframework.web.context.ContextLoaderServlet </servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet> <servlet-name>action</servlet-name> <servlet-class> org.apache.struts.action.ActionServlet </servlet-class> <init-param> <param-name>config</param-name> <param-value>/WEB-INF/struts-config.xml</param-value> </init-param> <init-param> <param-name>debug</param-name> <param-value>3</param-value> </init-param> <init-param> <param-name>detail</param-name> <param-value>3</param-value> </init-param> <load-on-startup>0</load-on-startup> </servlet> <servlet-mapping> <servlet-name>action</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> </web-app>

 

MD5加密

加入 MD5 支持，为了数据安全，因为不加一旦被黑，所有数据都被看到

不可逆向，为程序的安全性作保障

验证码 image.jsp

防止灌水



使用模板 temp.jsp 拷贝它做新的 JSP 页面

temp.html 做新的 HTML 页面

文件存放目录   分页 split_page.jsp







数据源配制

在 tomcat 的 servlet.xml 文件加入

<Context path="/myssh" docBase="E:\JAVA\SSHworkspace\MySSH\WebRoot" debug="5" reloadable="true" crossContext="true"> <Logger className="org.apache.catalina.logger.FileLogger" prefix="localhost_MysqlTest_log." suffix=".txt" timestamp="true"/> <Resource name="jdbc/myssh" auth="Container" type="javax.sql.DataSource"/> <ResourceParams name="jdbc/myssh"> <parameter> <name>factory</name> <value>org.apache.commons.dbcp.BasicDataSourceFactory</value> </parameter> <parameter> <name>maxActive</name> <value>100</value> </parameter> <parameter> <name>maxIdle</name> <value>30</value> </parameter> <parameter> <name>maxWait</name> <value>5000</value> </parameter> <parameter> <name>username</name> <value>root</value> </parameter> <parameter> <name>password</name> <value>123456</value> </parameter> <parameter> <name>driverClassName</name> <value>org.gjt.mm.mysql.Driver</value> </parameter> <parameter> <name>url</name> <value>jdbc:mysql://localhost:3306/myssh</value> </parameter> </ResourceParams> </Context> </Host> </Engine> </Service> </Server>
