Spring WebFlux无法注入RelationalEntityInformation |

1月 28, 2023 | Nix.Huang

开始UserRepository定义如下

@Repository
public class UserRepository extends  SimpleR2dbcRepository<User, Integer> {

    public UserRepository(RelationalEntityInformation<User, Integer> entity,
                          R2dbcEntityOperations entityOperations,
                          R2dbcConverter converter) {
        super(entity, entityOperations, converter);
    }
}

@Repository

public class UserRepository extends SimpleR2dbcRepository<User, Integer> {

public UserRepository(RelationalEntityInformation<User, Integer> entity,

R2dbcEntityOperations entityOperations,

R2dbcConverter converter) {

super(entity, entityOperations, converter);

}

报如下错误：

Parameter 0 of constructor in cn.javacoder.dao.UserRepository
required a bean of type' org.springframework.data.relational.repository.query.RelationalEntityInformation'
that could not be found.

RepositoryComponentProvider.InterfaceTypeFilter#match要求必须是接口，才会判断是否可以赋值给Repository

改成如下

@Repository
public interface UserRepository  extends R2dbcRepository<User, Integer> {
}

@Repository

public interface UserRepository extends R2dbcRepository<User, Integer> {

}
