@Transient申明非持久化属性

 

对于entity有些get方法是不需要和数据库关联的。需要用@Transient 注解

 

比如

 

@Transient
String getLengthInMeter() { ... } //transient property

 

@Transient
 public String  getReviewstatusDesc(){
  if(reviewstatus==null){
   return "";
  }else if("1".equals(reviewstatus)){
   return "安排评审";
  }else if("2".equals(reviewstatus)){
   return "已评审结束";
  }else if("0".equals(reviewstatus)){
   return "待安排";
  }else {
   return "";
  }
 }

 @Transient
 public String  getFundconclusionDesc(){
  if(fundconclusion==null){
   return ""; 
  }else if("1".equals(fundconclusion)){
   return "通过";
  }
  else if("0".equals(fundconclusion)){
   return "暂不资助";
  }else {
   return "";
  }
 }

 

 

 

官方hibernate3.5 annotation参考手册 对此属性有如下说明：

 

Every non static non transient property (field or method depending on the access type) of an entity
is considered persistent, unless you annotate it as @Transient. Not having an annotation for your
property is equivalent to the appropriate @Basic annotation. The @Basic annotation allows you to
declare the fetching strategy for a property
