mysql 日专中 十六进制数 问题

1.问题：用JDBC批量插入数据库（主从），主库正常插入，但是从库完法进行同步，查看日志发现在日志中的insert语句存在十六进制数。。。从而无法同步从数据库。


问题解决：更换jdbc驱动包，更新到mysql-connector-java-5.0.8-bin.jar或以上版本。。。
问题版本：mysql-connector-java-5.0.3-bin.jar

2.xml rpc中无法实现长连接。

PropertyHandlerMapping mapping = new PropertyHandlerMapping();
	        mapping.addHandler("PasswordModiServiceImpl", PasswordModiServiceImpl.class);
    		
		   MyWebServer webServer = new MyWebServer(8080);
	        webServer.getXmlRpcServer().setHandlerMapping(mapping);
	        webServer.getXmlRpcServer().setMaxThreads(2);
	        XmlRpcServerConfigImpl cfg = (XmlRpcServerConfigImpl)webServer.getXmlRpcServer().getConfig();
	        cfg.setKeepAliveEnabled(true);
	        
	        webServer.start();

======================

class MyWebServer extends WebServer {
    protected ThreadPool pool;
    MyWebServer(int pPort) {
        super(pPort);
    }
    public ThreadPool newThreadPool(){
        pool = new ThreadPool(getXmlRpcServer().getMaxThreads(), "XML-RPC"){
        };
        return pool;
    }
    int getNumThreads() {
        return pool.getNumThreads();
    }
}

========================

Map<String, String> map = new HashMap<String, String>();
		map.put(Customer.CUSTOMER_ID, "00000001");
		map.put(Customer.PW, "111111");
		map.put(Customer.SYSTEM_ID, "FX");

		Object[] params = new Object[] { map };
		long start=0;
 XmlRpcClient client = new XmlRpcClient();
         XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl();
         config.setServerURL(new URL("http://10.15.3.80:8080/"));
                
         
         client.setConfig(config);
         Ant a1=new Ant(client, params);
         Ant a2=new Ant(client, params);
         Ant a3=new Ant(client, params);
         Ant a4=new Ant(client, params);
         a1.start();
         a2.start();

===========================
try {
//this.wait();
for (int i = 0; i < 3; i++) {
Object[] result = (Object[]) client.execute("PasswordModiServiceImpl.process", params);
System.out.println(((Map) result[0]).get("SUCCESS_FLAG"));
}
} catch (Exception e) {
e.printStackTrace();
}
