java部分代码：

sql="insert into tao_user(user_email,user_qq,user_id,user_name,user_password,user_imagepath,user_field,user_starttime,user_type," +

"user_phone,user_problem_answer,user_problem) values(\'"+

tub.getUseremail()+"\',"+tub.getUserqq()+","+/*(Integer.parseInt(rn_max)+1)*/10+",\'"+

tub.getUsername()+"\',\'"+new SystemTool().getMD5Password(tub.getPassword())+"\',\'"+

rn_pic+"\',\'"+tub.getPassword()+"\',\'"+dateFormat.format(date)+"\',"+tub.getUsertype()+

","+tub.getUserphone()+",\'"+tub.getUserproblemanswer()+"\',\'"+tub.getUserproblem()+"\')";

System.out.println(sql);

sta.executeUpdate(sql);

boolean flag=sta.execute(sql);

打印的执行sql，以及报错信息：

insert into tao_user(user_email,user_qq,user_id,user_name,user_password,user_imagepath,user_field,user_starttime,user_type,user_phone,user_problem_answer,user_problem) values('12345@123.com',123456789,10,'wenzh123456','25F9E794323B453885F5181F1B624D0B','qwee','123456789','2014/08/23 17:01:29',1,123456789,'我很好','你好')

com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException: Duplicate entry '10' for key 1

在mysql客户端使用同一条sql语句，却可以执行：

执行结果：

mysql>insert into tao_user(user_email,user_qq,user_id,user_name,user_password,user_imagepath,user_field,user_starttime,user_type,user_phone,user_problem_answer,user_problem) values('12345@123.com',123456789,10,'wenzh123456','25F9E794323B453885F5181F1B624D0B','qwee','123456789','2014/08/23 17:01:29',1,123456789,'我很好','你好');

Query OK,1 row affected, 1 warning (9.03 sec)

谢谢，大家问题的根源找到了，由于编程不够细心，在此处多加了一个：

System.out.println(sql);

【sta.executeUpdate(sql);】

boolean flag=sta.execute(sql);
