前言
想要做網(wǎng)頁Web聊天系統(tǒng)股囊，但是如何對消息特殊字符以及敏感詞進行過濾颗胡、以及處理呢帖旨？
請見下方找田。
敏感消息過濾鏈設計
在這里插入圖片描述
代碼
不啰嗦直接上源碼：

String doFilter(String message);
}

public FilterChain addFilter(Filter filter) {
filters.add(filter);
return this;
}
public String doFilter(String message) {
AtomicReference<String> s = new AtomicReference<>(message);
filters.forEach(f -> s.set(f.doFilter(s.get())));
return s.get();
}
}

測試類：
package com.zzx.design.pattern.zzxdesignpattern.mashibin.zerenlian_pattern.sensitive_filter_chain;
import com.zzx.design.pattern.zzxdesignpattern.mashibin.zerenlian_pattern.sensitive_filter_chain.filter.*;
