Question

我收到的错误是：

java.lang.StackOverflowError 
        java.nio.Buffer.<init>(Buffer.java:176) 
        java.nio.ByteBuffer.<init>(ByteBuffer.java:259) 
        java.nio.HeapByteBuffer.<init>(HeapByteBuffer.java:52) 
        java.nio.ByteBuffer.wrap(ByteBuffer.java:350)

        java.lang.StringCoding.encode(StringCoding.java:272) 
        java.lang.String.getBytes(String.java:946)

只有在我在product hbm文件中添加了与productCategories的关系后才会添加此错误。请建议

productCategory和product hbm文件是：

<?xml version="1
<hibernate-mapping package="com.quinstreet.persistence.productCatalogue"
default-cascade="save-update">
<class
    name="com.quinstreet.persistence.productCatalogue.ProductCategoryDBVO"
    table="PRD_PRODUCT_CATEGORY" lazy="false">
            <cache usage="nonstrict-read-write" />
    <composite-id>
        <key-many-to-one name="product"
            class="com.quinstreet.persistence.product.ProductDBVO" column="PRODUCT_GUID" lazy="false"
            foreign-key="FK_PRD_PRODUCT_FK1" />
        <key-many-to-one name="category"
class="com.quinstreet.persistence.productCatalogue.CategoryMasterDBVO"
            column="CATEGORY_GUID" foreign-key="FK_PRD_CATEGORY_MASTER_FK1" />
    </composite-id>
    <property name="displaySequence" column="DISPLAY_SEQUENCE"
        type="java.lang.Integer" />
</class>
</hibernate-mapping>

在产品hbm中评论后，它的效果很好

   <set name="recommendations" table="PRD_PRODUCT_RECOMMENDATION" inverse="true" lazy="true" batch-size="25" fetch="select"> 
 <cache usage="nonstrict-read-write"/>   
  <key column="productguid" not-null="true"/> 
  <one-to-many class="com.quinstreet.persistence.productCatalogue.ProductRecommendationDBVO" /> 
</set>

Answer 1

确保在某些类中覆盖它而不是调用超级版本时不会调用相同的方法：

public void setWhatever(Whatever whatever) {
   super.setWhatever(whatever);
   this.whateverSet = true;
}

不

public void setWhatever(Whatever whatever) {
   setWhatever(whatever);
   this.whateverSet = true;
}
