我有一个实体类
@Entity
@Table(name = "rule")
public class Rule implements Cloneable, Serializable, IPojoGenEntity, IRule, SequencedEntity {
private String name;
private Service service;
//getter .. setter for service and name
public String getServiceName() {
return (this.service.getName());
}
public void setServiceName(String servicename) {
this.service.setName(servicename);
}
}
我通过 RulClass 对象获取服务名称时遇到异常
public String getServiceName() {
return (this.service.getName());
}
堆栈跟踪
Caused by: com.ibm.db2.jcc.b.SqlException: "RULE0_.SERVICENAME" is not valid in the context where it is used.

我们可以在实体类中使用这样的 getter 和 setter 吗?
