YOUNG博客项目设计书_v01.00_SSH项目结构创建。
1.项目结构创建
创建Maven的Web项目，目录结构如下：
添加素材和静态界面,并将其后缀改为.jsp。
配置pom.xml文件，搭建SSH 开发环境。
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.young.blog</groupId> <artifactId>blog_v001</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <name>blog_v001</name> <properties>

配置web.xml 文件
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:javaee="http://xmlns.jcp.org/xml/ns/javaee" xmlns:web="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <!-- spring --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <filter> <filter-name>encoding</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>encoding</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 配置opensessioninview解决懒加载,本质一个过滤器. --> <filter> <filter-name>OpenSessionInViewFilter</filter-name> <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
<init-param>
<param-name>flushMode</param-name>
<param-value>AUTO</param-value>
</init-param>
</filter> <filter-mapping> <filter-name>OpenSessionInViewFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!--struts2 --> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> <dispatcher>REQUEST</dispatcher> <dispatcher>FORWARD</dispatcher> </filter-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
在classpath下创建spring的配置文件applicationContext.xml和struts2的配置文件struts.xml。
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!-- 加载jdbc属性文件 --> <context:property-placeholder location="classpath:jdbc.properties" /> <!-- 配置连接池 --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="driverClass" value="${jdbc.driverClass}"></property> <property name="jdbcUrl" value="${jdbc.url}"></property> <property name="user" value="${jdbc.username}"></property> <property name="password" value="${jdbc.password}"></property> </bean> <!-- spring框架用于整合Hibernate的工厂bean --> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <!-- 注入Hibernate相关的属性 --> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.format_sql">true</prop> <prop key="hibernate.hbm2ddl.auto">update</prop> </props> </property> <!-- 注入Hibernate的映射文件 --> <property name="mappingLocations"> <value>classpath:/com/young/account/action/domain/User.hbm.xml</value> </property> </bean> <!-- class="" --> <!-- 事务管理器 --> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"/> </bean> <!-- 组件扫描 --> <context:component-scan base-package="com.bos"/> <!-- 引入注解解析器 --> <context:annotation-config/> <!-- 事务注解 --> <tx:annotation-driven /> </beans>
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd"> <struts> <constant name="struts.devMode" value="true"/> <!-- 加载国际化文件 --> <constant name="struts.custom.i18n.resources" value="message"/> <package name="basicstruts2" extends="struts-default"> <!-- 需要进行权限控制的页面访问 --> <action name="page_*_*"> <result name="success" type="dispatcher">/WEB-INF/pages/{1}/{2}.jsp</result> </action> </package> </struts>
最后添加数据库配置文件jdbc.properties和log4j.properties。
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.username=root
jdbc.password=root
jdbc.url=jdbc\:mysql\://127.0.0.1\:3306/kf_young
#log4j.rootLogger=warn,systemOut,logFile,logDailyFile,logRollingFile,logMail,logDB
#log4j.appender.systemOut= org.apache.log4j.ConsoleAppender
#log4j.appender.systemOut.layout= org.apache.log4j.PatternLayout
#log4j.appender.systemOut.layout.ConversionPattern= [%-5p][%-22d{yyyy/MM/dd HH\:mm\:ssS}][%l]%n%m%n
#log4j.appender.systemOut.Threshold= DEBUG
#log4j.appender.systemOut.ImmediateFlush= TRUE
#log4j.appender.systemOut.Target=System.out
此时SSH的基本运行环境就搭建好了。
最后我们再添加一些常用的工具类：
1.文件操作类FileUtils.java
package com.young.util; import java.io.IOException; import java.net.URLEncoder; import sun.misc.BASE64Encoder; public class FileUtils { /** * 下载文件时，针对不同浏览器，进行附件名的编码 * * @param filename * 下载文件名 * @param agent * 客户端浏览器 * @return 编码后的下载附件名 * @throws IOException */ @SuppressWarnings("restriction") public static String encodeDownloadFilename(String filename, String agent) throws IOException { if (agent.contains("Firefox")) { // 火狐浏览器 filename = "=?UTF-8?B?" + new BASE64Encoder().encode(filename.getBytes("utf-8")) + "?="; filename = filename.replaceAll("\r\n", ""); } else { // IE及其他浏览器 filename = URLEncoder.encode(filename, "utf-8"); filename = filename.replace("+"," "); } return filename; } }
MD5加密MD5Utils.java
package com.young.util; import java.math.BigInteger; import java.security.MessageDigest; import java.security.NoSuchAlgorithmException; public class MD5Utils { /** * 使用md5的算法进行加密 */ public static String md5(String plainText) { byte[] secretBytes = null; try { secretBytes = MessageDigest.getInstance("md5").digest( plainText.getBytes()); } catch (NoSuchAlgorithmException e) { throw new RuntimeException("没有md5这个算法！"); } String md5code = new BigInteger(1, secretBytes).toString(16);// 16进制数字 // 如果生成数字未满32位，需要前面补0 for (int i = 0; i < 32 - md5code.length(); i++) { md5code = "0" + md5code; } return md5code; } }
