我希望你不要把它标记为重复原因我检查了很多帖子答案而没有解决我的问题..我不能超越我的插入声明，这就像给我一个操作符的空对象，当我在defaut中将我的attributs设置为null，它将其成功插入数据库中的空对象
这是我的实体：
@Entity
@Table(name="operators")
public class Operator {
@Id
@GeneratedValue
private Integer id;
private String opName;
private String opCountry;
private Date opDate;
private Integer opMCC;
private Integer opCC;
private Integer opMNC;
private Integer opNC;
private String opPMN;
private String opDNS;
private String opAPN;
private String opMails;
private String opNums;
private String Comment;
public String getOpName() {
return opName;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public void setOpName(String opName) {
this.opName = opName;
}
public String getOpCountry() {
return opCountry;
}
public void setOpCountry(String opCountry) {
this.opCountry = opCountry;
}
public Date getOpDate() {
return opDate;
}
public void setOpDate(Date opDate) {
this.opDate = opDate;
}
public Integer getOpMCC() {
return opMCC;
}
public void setOpMCC(Integer opMCC) {
this.opMCC = opMCC;
}
public Integer getOpCC() {
return opCC;
}
public void setOpCC(Integer opCC) {
this.opCC = opCC;
}
public Integer getOpMNC() {
return opMNC;
}
public void setOpMNC(Integer opMNC) {
this.opMNC = opMNC;
}
public Integer getOpNC() {
return opNC;
}
public void setOpNC(Integer opNC) {
this.opNC = opNC;
}
public String getOpPMN() {
return opPMN;
}
public void setOpPMN(String opPMN) {
this.opPMN = opPMN;
}
public String getOpDNS() {
return opDNS;
}
public void setOpDNS(String opDNS) {
this.opDNS = opDNS;
}
public String getOpAPN() {
return opAPN;
}
public void setOpAPN(String opAPN) {
this.opAPN = opAPN;
}
public String getOpMails() {
return opMails;
}
public void setOpMails(String opMails) {
this.opMails = opMails;
}
public String getOpNums() {
return opNums;
}
public void setOpNums(String opNums) {
this.opNums = opNums;
}
public String getComment() {
return Comment;
}
public void setComment(String comment) {
Comment = comment;
}
}

如果我认为列'opAPN'不能为null，但是当我在数据库中将其设置为null时，它会传递给另一列并向我注入相同的异常.etc
