<!--[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]-->
public
class
DiskPersistenceListener
extends
AbstractDiskPersistenceListener {
<!--[if !supportEmptyParas]--> <!--[endif]-->
private
static
final
long
serialVersionUID
= 1L;
<!--[if !supportEmptyParas]--> <!--[endif]-->
private
static
final
String
CHARS_TO_CONVERT
=
"./\\ :;\"\'_?"
;
<!--[if !supportEmptyParas]--> <!--[endif]-->
public
char
[] getCacheFileName(String key) {
// <1> protected
改为
public
if
((key ==
null
) || (key.length() == 0)) {
throw
new
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 =
new
char
[sb.length()];
sb.getChars(0, fileChars.
length
, fileChars, 0);
return
fileChars;
}
<!--[if !supportEmptyParas]--> <!--[endif]-->
public
static
void
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]-->
