為什么我把javabean里面是屬性名改了就找不到了 匹配不上

本來是自己寫的name? 后來改成usename就出錯了

package example.dyh;

public class User {
?? ?
?? ?private String usename=null;
?? ?private String password=null;
?? ?public User() {
?? ?
?? ?}
?? ?public String getName() {
?? ??? ?return usename;
?? ?}
?? ?public void setName(String name) {
?? ??? ?this.usename = name;
?? ?}
?? ?public String getPassword() {
?? ??? ?return password;
?? ?}
?? ?public void setPassword(String password) {
?? ??? ?this.password = password;
?? ?}
?? ?

}
