hibernate映射视图，

但是这时由于视图没有主键，user.hbm.xml在配置时会出现把所有的字段都当成主键，也就是联合主键，但是主键不能为空，可我这里面的字段有的是可以为空的，这应该怎么办？？

下面这样配置就可以。

TzChaobiaoInfoView .java

public class TzChaobiaoInfoView implements java.io.Serializable {

// Fields

private TzChaobiaoInfoViewId id;

     private String khbh;
// private String sbbh;//主键
// private Date cbrq;//主键
    private Long dsdm;
    private Long ds;
    private Long sjys;
    private String cby;
    private Long cbqk;
    private String gsdz;
    private String khmc;
    private String cbqkmc;
    private String dsdmmc;

    // Constructors

    /** default constructor */
    public TzChaobiaoInfoView() {
    }

    /** full constructor */
    public TzChaobiaoInfoView(TzChaobiaoInfoViewId id) {
        this.id = id;
    }

// Property accessors

    public TzChaobiaoInfoViewId getId() {
        return this.id;
    }

    public void setId(TzChaobiaoInfoViewId id) {
        this.id = id;
    }

public String getKhbh() {
  return khbh;
}
public void setKhbh(String khbh) {
  this.khbh = khbh;
}

public Long getDsdm() {
  return dsdm;
}
public void setDsdm(Long dsdm) {
  this.dsdm = dsdm;
}
public Long getDs() {
  return ds;
}
public void setDs(Long ds) {
  this.ds = ds;
}
public Long getSjys() {
  return sjys;
}
public void setSjys(Long sjys) {
  this.sjys = sjys;
}
public String getCby() {
  return cby;
}
public void setCby(String cby) {
  this.cby = cby;
}
public Long getCbqk() {
  return cbqk;
}
public void setCbqk(Long cbqk) {
  this.cbqk = cbqk;
}
public String getGsdz() {
  return gsdz;
}
public void setGsdz(String gsdz) {
  this.gsdz = gsdz;
}
public String getKhmc() {
  return khmc;
}
public void setKhmc(String khmc) {
  this.khmc = khmc;
}
public String getCbqkmc() {
  return cbqkmc;
}
public void setCbqkmc(String cbqkmc) {
  this.cbqkmc = cbqkmc;
}
public String getDsdmmc() {
  return dsdmmc;
}
public void setDsdmmc(String dsdmmc) {
  this.dsdmmc = dsdmmc;
}

}

TzChaobiaoInfoViewId .java

public class TzChaobiaoInfoViewId implements java.io.Serializable {

// Fields

private String sbbh;
private Date cbrq;

// Constructors

    /** default constructor */
    public TzChaobiaoInfoViewId() {
    }

public String getSbbh() {
return sbbh;
}

public void setSbbh(String sbbh) {
this.sbbh = sbbh;
}

public Date getCbrq() {
return cbrq;
}

public void setCbrq(Date cbrq) {
this.cbrq = cbrq;
}
}
