默认构造函数未定义隐式超级构造函数 QueryDslRepositorySupport()。必须定义显式构造函数

Question

我使用 Spring Roo + Spring Data + QueryDSL，我有以下类/接口：

public interface FamilyAdvertisementRepositoryCustom {
}

@RooJpaRepository(domainType = FamilyAdvertisement.class)
public interface FamilyAdvertisementRepository extends FamilyAdvertisementRepositoryCustom {
}

public class FamilyAdvertisementRepositoryImpl extends QueryDslRepositorySupport implements FamilyAdvertisementRepositoryCustom {
   //NO CONSTRUCTOR
}

全部在以下包中：com.bignibou.repository;

使用以下配置：

<repositories base-package="com.bignibou.repository" />

但是，我收到此错误：

[ERROR] Failed to execute goal org.codehaus.mojo:aspectj-maven-plugin:1.2:compile (default) on project bignibou: Compiler errors : [ERROR] error at public class FamilyAdvertisementRepositoryImpl extends QueryDslRepositorySupport implements FamilyAdvertisementRepositoryCustom { [ERROR] ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ [ERROR] /home/julien/Documents/donnees/projets/site-garde-enfants/java/bignibou/src/main/java/com/bignibou/repository/FamilyAdvertisementRepositoryImpl.java:5:0::0 Implicit super constructor QueryDslRepositorySupport() is undefined for default constructor. Must define an explicit constructor

QueryDslRepositorySupport 类似乎不再有默认构造函数，而以前是这样。为什么会这样？？

我做错了什么？

引入更改是为了强制从 getBuilder() 返回的 Builder 为单个域类型。只需创建一个不带参数的构造函数，然后使用您为其实现存储库的域类型调用超类的构造函数。
