Springで外部結合したクエリをリストで取ってくる方法

前提・実現したいこと

SpringでServiceクラスを作成し、発行したクエリでリストを取ってきたいです。

一応取ってこれてはいるのですが、外部結合したテーブルがそれぞれ分割されて別の配列に入っているのを何とかしたいです。

Controller

Java
1package com.example.demo.haizokuMaster;
2
3import org.springframework.beans.factory.annotation.Autowired;
4import org.springframework.stereotype.Controller;
5import org.springframework.ui.Model;
6import org.springframework.web.bind.annotation.RequestMapping;
7
8@Controller
9public class HaizokuMasterController {
10
11	@Autowired
12	private HaizokuMasterService haizokuMasterService;
13
14	@RequestMapping(value = "/haizokuMaster/list")
15	public String list(Model model) {
16        var list = haizokuMasterService.findForHaizokuMaster();
17        model.addAttribute("list", list);
18        return "/haizokuMaster/list";
19	}
20
21}
22

Service

Java
1package com.example.demo.haizokuMaster;
2
3import javax.persistence.EntityManager;
4import javax.persistence.PersistenceContext;
5
6import org.springframework.beans.factory.annotation.Autowired;
7import org.springframework.stereotype.Service;
8import org.springframework.transaction.annotation.Transactional;
9
10@Service
11@Transactional
12public class HaizokuMasterService {
13
14	@Autowired
15	HaizokuMasterRepository shitenMasterRepositry;
16
17	@PersistenceContext
18	EntityManager entityManager;
19
20	public Object findForHaizokuMaster() {
21
22		Object results = entityManager
23                .createQuery("from ShitenMaster SM LEFT OUTER JOIN KoinMaster KM ON SM.shitenid = KM.shitenid")
24                .getResultList();
25
26        return results;
27	}
28
29}
