这是我的休息代码
@Path("Users")
public class ItemsResource extends stu{
@Context
private UriInfo context;
/**
* Creates a new instance of ItemsResource
*/
public ItemsResource() {
}
/**
* Retrieves representation of an instance of service.ItemsResource
* @return an instance of java.lang.String
*/
@GET
@Produces("text/plain")
public String getText() {
//TODO return proper representation object
throw new UnsupportedOperationException();
}
/**
* POST method for creating an instance of ItemResource
* @param content representation for the new resource
* @return an HTTP response with content of the created resource
*/
@POST
@Consumes("text/plain")
@Produces("text/plain")
public Response postText(@PathParam("id") int id,@PathParam("Password") String Password,
@PathParam("Username") String Username) {
//TODO
super.createText(id,Password,Username);
return Response.created(context.getAbsolutePath()).build();
// return "success";
}
/**
* Sub-resource locator method for {id}
*/
}
这是 stu.java
class stu {
public String createText(int id,String Username,String Password) {
//TODO
try
{
Class.forName("com.mysql.jdbc.Driver");
Connection con=DriverManager.getConnection("jdbc:mysql://localhost:3306/users","root","789456");
String query= "Insert into users (id,username,password) values('"+id+"','"+Username+"','"+Password+"')";
PreparedStatement stm = con.prepareStatement(query);
stm.executeUpdate(query);
} catch(ClassNotFoundException e){
System.err.println ("Sql Exception"+e);
} catch(SQLException e){
System.err.println ("Sql Exception"+e);
}
return "success";
}
}
