4. HttpSession实现

BinCatSession.java示例代码片段:

package com.anbai.sec.server.servlet;
import javax.servlet.ServletContext;
import javax.servlet.http.HttpSession;
import javax.servlet.http.HttpSessionContext;
import java.util.Enumeration;
import java.util.Map;
import java.util.concurrent.ConcurrentHashMap;
/**
 * BinCat Session实现
 */
public class BinCatSession implements HttpSession {
  private final String sessionID;
  // Http请求Session对象
  private final Map<String, Object> sessionMap = new ConcurrentHashMap<String, Object>();
  public BinCatSession(String sessionID) {
    this.sessionID = sessionID;
  }
  // 此处省略HttpSession接口中的大部分方法，仅保留几个示例方法...
  public Object getAttribute(String name) {
    return this.sessionMap.get(name);
  }
  public void setAttribute(String name, Object value) {
    this.sessionMap.put(name, value);
  }
}
