    @Autowired
    private SearchRepository repository;

    @Override

    }
}

Controller代码

        List<SearchModal> list = new ArrayList<>();
        SearchModal search = new SearchModal();
        search.setId(1);
        search.setName("test1");
        search.setUuid(UUID.randomUUID().toString().replaceAll("-",""));
        list.add(search);
         SearchModal search2 = new SearchModal();
        search2.setId(2);
        search2.setName("test2");
        search2.setUuid(UUID.randomUUID().toString().replaceAll("-",""));
        list.add(search);
