【问题描述】:
假设我有这样的实体:
public class Foo {
private long id;
private List<Bar> list = new ArrayList<>();
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public List<Bar> getList() {
return list;
}
public void setList(List<Bar> list) {
this.list = list;
}
/** helper method*/
public boolean isEmpty(){
return list.isEmpty();
}
}
以及对应的实体映射:
<?xml version="1.0" encoding="UTF-8" ?>
<entity-mappings xmlns="http://xmlns.jcp.org/xml/ns/persistence/orm"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence/orm"
version="2.1">
<entity class="Foo">
<table name="foo"/>
<attributes>
<id name="id"/>
<one-to-many name="list">
<!-- ... -->
</one-to-many>
<transient name="isEmpty"/>
</attributes>
</entity>
</entity-mappings>
我得到了这个例外:org.hibernate.PropertyNotFoundException: Could not locate setter method for property [Foo#empty]
我发现了一个类似的帖子 - HIbernate Mapping Exception: PropertyNotFoundException: Could not find a setter 并且有关于这种方法的 Trainsient 注释有所帮助。

您应该能够让 Hibernate 忽略您的方法,只需在 XML 中完全不包含它。
