1要有三个类分别是dubbo自定义filter，DataSource，存放的常量DataSoursePro

service层

1DubboProviderContextFilter

@Activate(group = Constants.PROVIDER)
public class DubboProviderContextFilter implements Filter {
    private Logger logger = LoggerFactory.getLogger(this.getClass());

    @Override
    public Result invoke(Invoker<?> invoker, Invocation invocation) throws RpcException {
        Result result = null;
        getAttachment(invoker, invocation);
        //执行业务逻辑
        result = invoker.invoke(invocation);
        return result;
    }

    private void getAttachment(Invoker<?> invoker, Invocation invocation) {
        try {
            Map<String, String> attachments = RpcContext.getContext().
                    setInvoker(invoker).setInvocation(invocation).getAttachments();
            String username = attachments.get("db_username");
            String password = attachments.get("db_password");

            //设置动态数据源用户名密码
            ProviderDataSoursePro.getInstance().setUserName(username);
            ProviderDataSoursePro.getInstance().setPassWord(password);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

2DynamicDataSource

public class DynamicDataSource implements DataSource {
    private static final Map dataSources = new HashMap();

    private DataSource defaultDataSource = null;

    private DataSource dataSource = null;

    public Connection getConnection() throws SQLException {
        return getDataSource().getConnection();
    }

    public Connection getConnection(String arg0, String arg1) throws SQLException {
        return getDataSource().getConnection(arg0, arg1);
    }

    public PrintWriter getLogWriter() throws SQLException {
        return getDataSource().getLogWriter();
    }

    public int getLoginTimeout() throws SQLException {
        return getDataSource().getLoginTimeout();
    }

    public void setLogWriter(PrintWriter arg0) throws SQLException {
        getDataSource().setLogWriter(arg0);
    }

    public void setLoginTimeout(int arg0) throws SQLException {
        getDataSource().setLoginTimeout(arg0);
    }

    public DataSource getDataSource(String dataSourceName) {
        System.out.println("service.getDataSource("+dataSourceName+")");
        if ((dataSourceName == null) || (dataSourceName.equals(""))) {
            return this.dataSource;
        }
        if (dataSources.get(dataSourceName) != null) {
            return (DataSource) dataSources.get(dataSourceName);
        }
        return createDataSource(ProviderDataSoursePro.getInstance().getUserName(),
                ProviderDataSoursePro.getInstance().getPassWord());
    }

    public void setDataSource(DataSource dataSource) {
        this.dataSource = dataSource;
    }

    public DataSource getDataSource() {
        System.out.println("service.getDataSource()");
        String sp = ProviderDataSoursePro.getInstance().getUserName();
        return getDataSource(sp);
    }

    public DataSource createDataSource(String userName, String password) {
        System.out.println("service.createDataSource:userName="+userName+";password="+password);
        DruidDataSource s = new DruidDataSource();
        DruidDataSource ts = (DruidDataSource) this.defaultDataSource;
        s.setUsername(userName);
        s.setPassword(password);
        s.setUrl(ts.getUrl());
        s.setDriverClassName(ts.getDriverClassName());
        dataSources.put(userName, s);
        return s;
    }

    public DataSource getDefaultDataSource() {
        return this.defaultDataSource;
    }

    public void setDefaultDataSource(DataSource defaultDataSource) {
        this.defaultDataSource = defaultDataSource;
    }

    public boolean isWrapperFor(Class<?> iface) throws SQLException {
        return false;
    }

    public <T> T unwrap(Class<T> iface) throws SQLException {
        return null;
    }

    @Override
    public Logger getParentLogger() throws SQLFeatureNotSupportedException {
        return null;
    }
}

3ProviderDataSoursePro

public class ProviderDataSoursePro {
    private String userName;
    private String passWord;
    private static ProviderDataSoursePro instance = null;

    public static ProviderDataSoursePro getInstance() {
        if (instance == null) {
            instance = new ProviderDataSoursePro();
        }
        return instance;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getPassWord() {
        return passWord;
    }

    public void setPassWord(String passWord) {
        this.passWord = passWord;
    }
}

                </includes>

2模拟登陆

通过获取已经在缓存中username来找到他对应的password

在重新创建的jdbc的配置文件中获取url_lsk来实现二次登录历史库

public class SSOController implements Controller {
   
   private RedisTemplate<String, String> redisTemplate;
   
   @Override
   public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) {
      SessionUser    suser = SecureTool.getCurrentLoginUser();
      String username = suser.getUserName();
      String original_pwd = redisTemplate.opsForValue().get(username);//从redis获取key的value值
      byte[] src = original_pwd.getBytes();
      String password = Endecrypt.getBase64Encode(src);
//    String password =original_pwd;
      //获取jdbc.properties配置文件中url_lsk
      InputStream input = null;
      try {
         input = new FileInputStream(new File(request.getRealPath("") + "/WEB-INF/config/jdbc.properties"));
      } catch (FileNotFoundException e) {
         e.printStackTrace();
      }
      Properties pro = new Properties();
      try {
         pro.load(input);
      } catch (IOException e) {
         e.printStackTrace();
      }
      String url_lsk = pro.getProperty("url_lsk");
      String lsk_id = request.getParameter("p_id");
      url_lsk += lsk_id;//url添加lsk_id参数
      HttpSession usersession = request.getSession(false);
      usersession.invalidate();
      
      //模拟登陆
      PrintWriter out;
      try {
         out = response.getWriter();
         out.print("<script type='text/javascript'>");
         out.print("document.write(\"<form id='url' method='post' action='"+url_lsk+"'>\");");
         out.print("document.write(\"<input type='hidden' name='j_username' value='" +username + "' />\");");
         out.print("document.write(\"<input type='hidden' name='j_password' value='"+password+"' />\");");
         out.print("document.write(\"<input type='hidden' name='j_captcha_response' />\");");
         out.print("document.write('</form>');");
         out.print("document.getElementById('url').submit();");
         out.print("</script>");
      } catch (IOException e) {
         e.printStackTrace();
      }
      return null;
   }

   public RedisTemplate<String, String> getRedisTemplate() {
      return redisTemplate;
   }

   public void setRedisTemplate(RedisTemplate<String, String> redisTemplate) {
      this.redisTemplate = redisTemplate;
   }

}

3在已有的LoginAuthenticationSuccesssHandler（security-end.xml 中配好）中模拟登录后，进入该方法时插入（注意SpObserver等同于web层ConsumerDataSoursePro）

SpObserver.putName(lsk.getBf_standby1());
SpObserver.putPass(lsk.getBf_standby2());

后，在经过web层的自定义的过滤器和DataSource，最后就会成功进入备用历史库了（经过

DubboConsumerContextFilter的setAttachment方法进行插入username和password然后在DubboProviderContextFilter的getAttachment进行接收然后在service层进行换库）
public class LoginAuthenticationSuccesssHandler implements
		AuthenticationSuccessHandler {

	private Logger log = Logger.getLogger(LoginAuthenticationSuccesssHandler.class);
	
	private String defaultUrl;
	
	private String defaultUrl2;

	}

	public void setLskService(LskService lskService) {
		this.lskService = lskService;
	}

	@Override
	public void onAuthenticationSuccess(HttpServletRequest request,
			HttpServletResponse response, Authentication authentication) throws IOException,

		String username = request.getParameter("j_username");
		Map<String,Integer> pwdWrongMap = globalconfig.getPwdWrongMap();

		if(pwdWrongMap.containsKey(username)){
			pwdWrongMap.put(username, 0);
		}

		if(lsk_id != null){
			try {

3退出历史库经过exitbak方法

首先将相关session中的参数删除掉，然后将常量(SpObserver等同于web的ConsumerDataSourseProlieli里的内容置null这样就可以恢复默认数据源）

 public ModelAndView exitBak(HttpServletRequest request, HttpServletResponse response) {
		try {
			request.getSession().removeAttribute("treeObject");
			request.getSession().removeAttribute("dynamicDataSource_UserName");
			request.getSession().removeAttribute("dynamicDataSource_UserPass");
			request.getSession().removeAttribute("dynamicDataSource_Date");
			request.getSession().removeAttribute("lsk");
			request.getSession().removeAttribute("odbc");
			SpObserver.putName(null);
			SpObserver.putPass(null);
			SessionUser	suser = SecureTool.getCurrentLoginUser();
			String username = suser.getUserName();
			String original_pwd = redisTemplate.opsForValue().get(username).toString();//从redis获取key的value值
			byte[] src = original_pwd.getBytes();
			String password = Endecrypt.getBase64Encode(src);
			//获取jdbc.properties配置文件中url_main
			InputStream input = null;
			try {
				//input = new FileInputStream(new File(request.getRealPath("") + "/WEB-INF/config/jdbc.properties"));
				input = new FileInputStream(new File(this.getServletContext().getRealPath("") + "/WEB-INF/config/jdbc.properties"));
			} catch (FileNotFoundException e) {
				e.printStackTrace();
			}
			Properties pro = new Properties();
			try {
				pro.load(input);
			} catch (IOException e) {
				e.printStackTrace();
			}
			String url_main = pro.getProperty("url_main");
			
			HttpSession usersession = request.getSession(false);
			usersession.invalidate();
			
			//数据源切换回默认
			SpObserver.putName("");
			SpObserver.putPass("");
			
			PrintWriter out;
			out = response.getWriter();
			out.print("<script type='text/javascript'>");
			out.print("document.write(\"<form id='url' method='post' action='"+url_main+"'>\");");
			out.print("document.write(\"<input type='hidden' name='j_username' value='" +username + "' />\");");
			out.print("document.write(\"<input type='hidden' name='j_password' value='"+password+"' />\");");
			out.print("document.write(\"<input type='hidden' name='j_captcha_response' />\");");
			out.print("document.write('</form>');");
			out.print("document.getElementById('url').submit();");
			out.print("</script>");
		} catch (IOException e) {
			e.printStackTrace();
		}
		return null;
	}
