![KeyValFilter]( "KeyValFilter")
本文介绍了匿名类的NotSerializableException的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个用于过滤项目的接口：
public interface KeyValFilter extends Serializable {
public static final long serialVersionUID = 7069537470113689475L;
public boolean acceptKey（String iKey，Iterable< String> iValues）;
public boolean acceptValue（String iKey，String value）;
}
以及包含KeyValFilter类型成员的类。
public class KeyValFilterCollector extends KeyValCollectorSkeleton {
/ **
*
* /
private static final long serialVersionUID = -3364382369044221888L;
KeyValFilter过滤器;
public KeyValFilterCollector（KeyValFilter filter）{
this.filter = filter;
}
当我尝试使用实现KeyValFilter的匿名类来启动KeyValFilterCollector时： （KeyValFilter（））{
private static final long serialVersionUID = 7069537470113689475L;
public boolean acceptKey（） （字符串值：iValues）{
if（value.startsWith（1：））
return true;
}
返回false;
}
public boolean acceptValue（String iKey，String value）{
返回value.startsWith（0：）;
}
}）;
我得到一个异常：线程main中的异常java.io.NotSerializableException
我写了Serializable的匿名类吗？
解析方案 www.oracle.com/technetwork/java/effectivejava-136174.html\"> Effective Java，2nd Edition ，Item 74：
I have an interface for filtering items:
public interface KeyValFilter extends Serializable{
public static final long serialVersionUID = 7069537470113689475L;
public boolean acceptKey(String iKey, Iterable<String> iValues);
public boolean acceptValue(String iKey, String value);
}
and a class containing a member of type KeyValFilter .
public class KeyValFilterCollector extends KeyValCollectorSkeleton {
/**
*
*/
private static final long serialVersionUID = -3364382369044221888L;
KeyValFilter filter;
public KeyValFilterCollector(KeyValFilter filter){
this.filter=filter;
}
When I try to initiate the KeyValFilterCollector with an anonymous class implementing KeyValFilter :
new KeyValFilterCollector(new KeyValFilter(){
private static final long serialVersionUID = 7069537470113689475L;
public boolean acceptKey(String iKey, Iterable<String> iValues){
for (String value : iValues) {
if (value.startsWith("1:"))
return true;
}
return false;
}
public boolean acceptValue(String iKey, String value){
return value.startsWith("0:");
}
});
I get an exception: Exception in thread "main" java.io.NotSerializableExceptionHow do I make the anonymous class I wrote Serializable?
