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。

在classpath下创建spring的配置文件applicationContext.xml和struts2的配置文件struts.xml。

        <!-- 注入Hibernate相关的属性 -->
        <property name="hibernateProperties">
            <props>

        </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("
", "");
            } 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;
    }

}
