用hibernate 可以修改 符合主键里的部分字段吗?应该怎么办?
public class RepH201 implements java.io.Serializable {
private RepH201Id id;
private String ftableno1;
private String ftableno2;
private String ftableno3;
private String fbuildaddrcode;
.
.
.
(属性太多省略。。)
}
public class RepH201Id implements java.io.Serializable {
private String fmonth;
private String funitcode;
private String fitemname;
....get() set()方法.....
public boolean equals(Object other) {
if ( (this == other ) ) return true;
if ( (other == null ) ) return false;
if ( !(other instanceof RepH201Id) ) return false;
RepH201Id castOther = ( RepH201Id ) other;
return ( (this.getFmonth()==castOther.getFmonth()) || ( this.getFmonth()!=null && castOther.getFmonth()!=null && this.getFmonth().equals(castOther.getFmonth()) ) )
&& ( (this.getFunitcode()==castOther.getFunitcode()) || ( this.getFunitcode()!=null && castOther.getFunitcode()!=null && this.getFunitcode().equals(castOther.getFunitcode()) ) );
&& ( (this.getFitemname()==castOther.getFitemname()) || ( this.getFitemname()!=null && castOther.getFitemname()!=null && this.getFitemname().equals(castOther.getFitemname()) ) );
}
public int hashCode() {
int result = 17;
result = 37 * result + ( getFmonth() == null ? 0 : this.getFmonth().hashCode() );
result = 37 * result + ( getFunitcode() == null ? 0 : this.getFunitcode().hashCode() )
result = 37 * result + ( getFitemname() == null ? 0 : this.getFitemname().hashCode() );
return result;
