我是新來的春天。我想爲下面的代碼編寫一個bean定義。彈簧整合的豆的定義
package com.abc.common.filter;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
import org.apache.log4j.Logger;
public class RegexFilter implements Filter<String> {
Logger logger = Logger.getLogger(RegexFilter.class);
private Pattern regex;
private String lastMatch;
public RegexFilter(String regexString) {
this.lastMatch = null;
regex = Pattern.compile(regexString, Pattern.UNICODE_CHARACTER_CLASS);
}
@Override
public boolean matches(String text) {
text = text.toLowerCase();
if (text == null) {
logger.error("No text set for matching!");
return false;
}
Matcher matcher = regex.matcher(text);
if (matcher.find(0)) {// always start at index 0
this.lastMatch = matcher.group();
if (logger.isDebugEnabled()) {
logger.debug(matcher.group() + " found!");
}
return true;
}
return false;
}
public String getLastMatch(){
return this.lastMatch;
}
}
我卡在這行後,我不知道如何包含索引或名稱?對索引和值進行更多的澄清將更有幫助。
<bean id="regexfilter" class="com.abc.common.filter.RegexFilter" />
<constructor-arg name="regexString" />
</bean>
你會得到什麼錯誤?或者你在哪裏遇到麻煩? – reos
