通过netweaver跳转向tomcat中的项目传递登录者工号，单点登录

1 .  ManageController .java

package com.want.address.controller;

import java.net.URLEncoder;

import javax.servlet.http.Cookie;

import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.servlet.ModelAndView;

import com.want.address.mo.UserContext;

import com.want.address.threadlocal.UserThreadLocal;

/**

 * 

 * @author 00301957

 *当前登录人跳转controller

 */

@Controller

public class ManageController {

@RequestMapping(value="manage")

    public ModelAndView testLogin(HttpServletResponse response) throws Exception{
ModelAndView modelAndView = new ModelAndView("manage");
       // 获取当前登录人员信息

        UserContext userContext = UserThreadLocal.get();

        //生成16位随机字符串

//        String string = "qwertyuiopasdfghjklzxcvbnmQAZWSXEDCRFVTGBYHNUJMIKOLP";

//        StringBuffer sb = new StringBuffer();

//        int len = string.length();

//        for (int i=0; i<16; i++) {

//            sb.append(string.charAt((int)Math.round(Math.random()*(len-1))));ssss//        }

//        String keyStr = sb.toString();

// String plainText = userContext.getAccount();

//加密工号

// String encUserCode = CryptAES.AES_Encrypt(keyStr, plainText);

modelAndView.addObject("key", userContext.getAccount());

//设置cookie
Cookie cookie = new Cookie("encUserCode", URLEncoder.encode("encUserCode", "UTF-8"));
cookie.setDomain("want-want.com");
cookie.setPath("/");

        response.addCookie(cookie);

        return modelAndView;

    }
}

2. UserThreadLocal.java

package com.want.address.threadlocal;

import com.want.address.mo.UserContext;

public class UserThreadLocal {

    private static final ThreadLocal<UserContext> USER = new ThreadLocal<UserContext>();
    public static void set(UserContext userContext) {
        USER.set(userContext);
    }
    public static UserContext get() {
        return USER.get();
    }
    public static void clear() {
        set(null);
    }

}

3. UserContext .java

package com.want.address.mo;

public class UserContext {

    public static final String USER_CONTEXT_KEY = "discussUserContext";

    private String account;

    private String userName;

    public String getAccount() {

        return account;

    }

    public void setAccount(String account) {

        this.account = account;

    }

    public String getUserName() {

        return userName;

    }

    public void setUserName(String userName) {

        this.userName = userName;

    }

}

4. 过滤器UserContextHandlerInterceptor .java

package com.want.address.intercepter;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import javax.servlet.http.HttpSession;

import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;

import com.sap.security.api.IUser;

import com.sap.security.api.UMFactory;

d0ee

import com.want.address.mo.UserContext;

import com.want.address.threadlocal.UserThreadLocal;

public class UserContextHandlerInterceptor extends HandlerInterceptorAdapter {

    @Override

    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)

            throws Exception {

        HttpSession session = request.getSession();

        UserContext userContext = (UserContext) session.getAttribute(UserContext.USER_CONTEXT_KEY);

        // 判断session中有没有记录当前登录人员的信息

        if (userContext == null) {

            // 创建空的 UserContext

            userContext = new UserContext();

            // 未登录清空ThreadLocal中的数据

            UserThreadLocal.clear();

            // 取得当前登录人员对应的account

            IUser user = UMFactory.getAuthenticator().forceLoggedInUser(request, response);

            userContext.setAccount(user.getUniqueName());

            userContext.setUserName(user.getLastName());

            // 将 UserContext 加入到 Session

            session.setAttribute(UserContext.USER_CONTEXT_KEY, userContext);

        }

        // 将用户存在ThreadLocal中

        UserThreadLocal.set(userContext);

        return super.preHandle(request, response, handler);

    }

}
