java - 泛型的代码模型窄

Question

我想生成一个新类，如下所示：

public class QueryBuilder_QueryField
extends AbstractQueryBuilder<QueryBuilder_QueryField>

我试过了，但它并没有缩小延伸范围......

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

但结果却像

public class QueryBuilder_QueryField
extends AbstractQueryBuilder

有任何想法吗？

我相信你需要在通过课程之前缩小范围_extends()：

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

生成：

public class QueryBuilder_QueryField
extends AbstractQueryBuilder<QueryBuilder_QueryField>
