将参数传递给jpa转换器

Converter 在我的代码中用于多个类似的情况。我有一组子类,我只想用一个来处理 转换器 能够定义

public class GenericConverter implements AttributeConverter<MyGenericClass , Integer> {
.
.
.
    public MyGenericClass convertToEntityAttribute(Integer arg0) {
                // return a certain sub class here according to an attribute / an initialization method / etc
            }

@Convert( converter = GenericConverter.class \*pass something here\* )
    protected SubClass1 var1;

@Convert( converter = GenericConverter.class \*pass something here\* )
    protected SubClass2 var2;

@Convert( converter = GenericConverter.class, \*pass something here\* )
    protected SubClass3 var3;
