java - 泛型的代码模型

我想生成一个新类，如下所示:

public class QueryBuilder_QueryField
extends AbstractQueryBuilder<QueryBuilder_QueryField>

我尝试了这个但是它并没有缩小扩展范围...

JCodeModel model = new JCodeModel();
String fqcn = packageName + "." + className;
JDefinedClass builderClass = model._class(fqcn);
builderClass._extends(AbstractQueryBuilder.class).narrow(builderClass);

但最终却像

public class QueryBuilder_QueryField
extends AbstractQueryBuilder

有任何想法吗？

最佳答案

我相信您需要先缩小范围，然后再将类传递给_extends():

JCodeModel model = new JCodeModel();
String fqcn = packageName + "." + className;
JDefinedClass builderClass = model._class(fqcn);
builderClass._extends(model.ref(AbstractQueryBuilder.class).narrow(builderClass));

产生:

public class QueryBuilder_QueryField
extends AbstractQueryBuilder<QueryBuilder_QueryField>
