Servlet, MySQL Chinese garbled

1, servlet Chinese garbled:

In the Dopost or Doget method, add the following two lines:

Response.setcontenttype ("Text/html;charset=utf-8");
Request.setcharacterencoding ("UTF-8");

2, MySQL Chinese garbled:

Connection conn=drivermanager.getconnection ("Jdbc:mysql://localhost:3306/test? Useunicode=true&characterencoding=utf-8 "," Root "," ");

Test is the database name, followed by the Chinese code is UTF-8

Root is the user name, my database does not have a password, all the last is empty ("")
