推土机定制转换器适用于所有领域

Question

I just declared the following converter

<converter type="co.mine.converter.ProductToNameConverter">
          <class-a>java.lang.String</class-a>
          <class-b>java.lang.String</class-b>
</converter>

and in the mapping file:

<field custom-converter="co.mine.converter.ProductToNameConverter">
        <a>productId</a>
        <b>product</b>
</field>

but for every mapping field, where source is String and destination is String also, this converter has been called. So how should I avoid such behavior? In other words, I only want that converter to work on productId and product .

Answer 1

If you want the converter to work only for productId and product your second configuration is enough. Remove the first.
