改变缓存目录

<!--[if !supportEmptyParas]--> <!--[endif]-->

一、修改 DiskPersistenceListener.java 文件：

<!--[if !supportEmptyParas]--> <!--[endif]-->

package com.jh.xh.hibernate.oscache;

<!--[if !supportEmptyParas]--> <!--[endif]-->

import com.opensymphony.oscache.plugins.diskpersistence.AbstractDiskPersistenceListener;

<!--[if !supportEmptyParas]--> <!--[endif]-->

publicclass DiskPersistenceListener extends AbstractDiskPersistenceListener {

<!--[if !supportEmptyParas]--> <!--[endif]-->

    privatestaticfinallongserialVersionUID = 1L;

<!--[if !supportEmptyParas]--> <!--[endif]-->

    privatestaticfinal String CHARS_TO_CONVERT = "./// :;/"/'_?";

<!--[if !supportEmptyParas]--> <!--[endif]-->

    publicchar[] getCacheFileName(String key) { // <1> protected 改为 public

       if ((key == null) || (key.length() == 0)) {

           thrownew IllegalArgumentException("Invalid key '" + key

                  + "' specified to getCacheFile.");

       }

<!--[if !supportEmptyParas]--> <!--[endif]-->

      char[] chars = key.toCharArray();

<!--[if !supportEmptyParas]--> <!--[endif]-->

        StringBuffer sb = new StringBuffer(chars.length + 10);

<!--[if !supportEmptyParas]--> <!--[endif]-->

       for (int i = 0; i < chars.length; i++) {

           char c = chars[i];

           int pos = CHARS_TO_CONVERT.indexOf(c);

<!--[if !supportEmptyParas]--> <!--[endif]-->

           if (pos >= 0) {

               sb.append('_');

               sb.append(i);

           } else {

               sb.append(c);

           }

           if (i % 3 == 2) {    // <2> 添加此行代码,每三个字符做为目录名；

               sb.append('/');

           }

       }

        sb.append('0');

      char[] fileChars = newchar[sb.length()];

        sb.getChars(0, fileChars.length, fileChars, 0);

        return fileChars;

    }

<!--[if !supportEmptyParas]--> <!--[endif]-->

    publicstaticvoid main(String str[]) {

        System.out.println(new DiskPersistenceListener().getCacheFileName("12341dfkaklakasdfadklskadllkklasdf"));

<!--[if !supportEmptyParas]--> <!--[endif]-->

    }

}

<!--[if !supportEmptyParas]--> <!--[endif]-->

<!--[if !supportEmptyParas]--> <!--[endif]-->

二、修改 oscache.properties 文件：

cache.persistence.class=com.jh.xh.hibernate.oscache.DiskPersistenceListener

<!--[if !supportEmptyParas]--> <!--[endif]-->
