在使用Ehcache作为网站的页面缓存时，可能会遇到一个问题：当用户按住F5不断刷新页面，在Tomcat的输出日志中会产生如下错误：
ClientAbortException: java.net.SocketException: Software caused connection abort: socket write error
...
Caused by: java.net.SocketException: Software caused connection abort: socket write error总之，就是socket write error错误。
实际上，这是由于用户在按住F5时，不断的发出请求，但是，每一次请求并不完整。用户发出一个请求，立马又中断了这个请求。在服务器端，由于Ehcache对页面进行了缓存，Ehcache负责向用户输出缓存的内容。我们查看EhCache的CachingFilter的源代码，其中，writeContent方法即负责向用户输出内容（当然，一般我们选择配置net.sf.ehcache.constructs.web.filter.SimplePageCachingFilter，SimplePageCachingFilter继承了CachingFilter类）：
protected void writeContent(final HttpServletRequest request,
final HttpServletResponse response, final PageInfo pageInfo)
throws IOException, ResponseHeadersNotModifiableException {
byte[] body;
boolean shouldBodyBeZero = ResponseUtil.shouldBodyBeZero(request,
pageInfo.getStatusCode());
if (shouldBodyBeZero) {
body = new byte[0];
} else if (acceptsGzipEncoding(request)) {
body = pageInfo.getGzippedBody();
if (ResponseUtil.shouldGzippedBodyBeZero(body, request)) {
body = new byte[0];
} else {
ResponseUtil.addGzipHeader(response);
}
} else {
body = pageInfo.getUngzippedBody();
}
response.setContentLength(body.length);
OutputStream out = new BufferedOutputStream(response.getOutputStream());
out.write(body);
out.flush(); // 这里会产生socket write error
}在这里，out.flush()方法负责输出内容的最后刷新。显然，如果用户在服务器向用户发送数据的时候，中断了请求，服务器则会产生ClientAbortException: java.net.SocketException: Software caused connection abort: socket write error的错误。
当然，这是一种合理的机制。但是，如果后台一直在输出大量的错误日志信息，那么无疑不是我们想要的。那么，如何解决这个问题？
这里，我们可以通过继承net.sf.ehcache.constructs.web.filter.SimplePageCachingFilter，实现一个自己的Filter类：
import java.io.IOException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import net.sf.ehcache.constructs.web.PageInfo;
import net.sf.ehcache.constructs.web.ResponseHeadersNotModifiableException;
import net.sf.ehcache.constructs.web.filter.SimplePageCachingFilter;
public class MySimplePageCachingFilter extends SimplePageCachingFilter {
protected void writeContent(final HttpServletRequest request, final HttpServletResponse response, final PageInfo pageInfo) throws IOException,
ResponseHeadersNotModifiableException {
try {
super.writeContent(request, response, pageInfo);
} catch (IOException e) {
System.out.println("访问频率过快！");
}
}
}这里，我们重写writeContent方法，用try catch处理该方法，此时，可以保证在Tomcat的日志记录中，不出现大量的socket write error日志信息。
