我使用 Spring Roo + Spring数据 + 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
}
以下所有内容:com.bignibou.repository;
使用以下配置:
<repositories base-package="com.bignibou.repository" />
然而,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
似乎 QueryDslRepositorySupport 类不再具有默认构造函数,而之前就是这种情况。为什么???
我错了什么?
答案 0 :(得分:3)
引入了更改以强制从Builder
返回getBuilder()
到单个域类型。只需创建一个没有参数的构造函数,并使用您为其实现存储库的域类型调用超类的构造函数。
