Question

存储库类

package jerceka.workhard.demo;

import java.util.List;

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.rest.core.annotation.RepositoryRestResource;
import org.springframework.stereotype.Repository;

@Repository
@RepositoryRestResource(collectionResourceRel="account",path="account")
public interface Repo extends JpaRepository<Account, Integer>{
    List<Account> findByage(int age);
    List<Account> findByname(String name);
    List<Account> deleteByName(String name);

}

控制器类

package jerceka.workhard.demo;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.DeleteMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class AccountController {
    @Autowired
    private Repo repo;
    @DeleteMapping("Account/{name}")
    public List<Account> deleteWithName(@PathVariable("name")String name){
        repo.deleteByName(name);
        return repo.findAll(); 
    }
}

给我那个错误没有用于当前线程的具有实际事务的EntityManager-无法可靠地处理“删除”调用

DeleteByName无法正常工作，但是findByName有效吗？
