示例代码
例
In this example, an address parameter is read and trimmed of whitespace.
bad Java
String address = request.getParameter("address");
address = address.trim();
String updateString = "UPDATE shippingInfo SET address='?' WHERE email='cwe@example.com'";
emailAddress = con.prepareStatement(updateString);
emailAddress.setString(1, address);
address = address.trim();
String updateString = "UPDATE shippingInfo SET address='?' WHERE email='cwe@example.com'";
emailAddress = con.prepareStatement(updateString);
emailAddress.setString(1, address);
If the value of the address parameter is null (undefined), the servlet will throw a NullPointerException when the trim() is attempted.
