Java结果集getString奇怪吗?

address.setAddressLine1(rs.getString("AddressLine1"));
address.setAddressLine2(rs.getString("AddressLine2"));

当我调试并检查rs.getString(“AddressLine1”)时,调试器会说我有一个30个字符的字符串:“ATTN:ACCOUNTS Payment”(尾部空格已删除)。但是,当我在这一行之后立即检查address对象时,它报告addressLine1是一个30个字符的字符串 空间

当我调试并检查rs.getString(“AddressLine2”)时,调试器会说我有一个23个字符的字符串:“10个街道”(尾部空格已删除)。当我在这行之后立即检查address对象时,它报告addressLine2为 无效的 .

真正让我抓狂的是,并不是所有的价值观都会发生这种情况,只有少数价值观。

public class Address implements java.io.Serializable {

 private static final long serialVersionUID = 1L;
 private String addressLine1; 
 private String addressLine2; 

 public String getAddressLine1() {
  return addressLine1;
 }

 public void setAddressLine1(String addressLine1) {
  this.addressLine1 = addressLine1;
 }

 public String getAddressLine2() {
  return addressLine2;
 }

 public void setAddressLine2(String addressLine2) {
  this.addressLine2 = addressLine2;
 }
}
