对于默认构造函数，隐式超级构造函数QueryDslRepositorySupport（）未定义。必须定义一个明确的构造

Question

我用Spring Roo的 + 春数据 + QueryDSL和我有以下类/接口：

public interface FamilyAdvertisementRepositoryCustom { 
} 

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

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

都在下列包：com.bignibou.repository;

有了以下配置：

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

但是，我得到t他的错误：

[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 

看来QueryDslRepositorySupport类不再有默认的构造函数，而之前是这样的情况。这是为什么？？

我出错了？

更改是为了强制将Builder从getBuilder()返回到单个域类型中。只需创建一个没有参数的构造函数，并调用超类的构造函数，并使用您实现该存储库的域类型。
