Java 如何在SpringDataREST中为测试填充数据？

我在使用自定义控制器对SpringDataREST应用程序进行单元测试时遇到问题

@RepositoryRestResource(path = "channels")
public interface ChannelsRepository extends PagingAndSortingRepository<Channel, Long> {
}

@RepositoryRestResource(path = "systems")
public interface SystemRepository extends PagingAndSortingRepository<System, String>{
}



@RestController
public class SystemController {

    private String query = "select a.id as fromId, b.id as toId\n" +
            "from channel a, channel b\n" +
            "where ST_Distance_Spheroid(\n" +
            "\ta.coordinates,\n" +
            "\tb.coordinates,\n" +
            "\t'SPHEROID[\"WGS 84\",6378137,298.257223563]'\n" +
            ") <= :criticalDistance and a.id != b.id";

    @Autowired
    private EntityManager manager;

    @Autowired
    private SystemRepository repository;

    @RequestMapping(value="systems/{systemId}/graph", method = RequestMethod.GET)
    public Map<BigInteger, List<BigInteger>> createNeighbourhsGraph(@PathVariable("systemId") String systemId,
                                                                    @RequestParam(value = "distance") double distance) {
        List<Object[]> results =  manager.createNativeQuery(query).setParameter("criticalDistance", distance).getResultList();
        Map<BigInteger, List<BigInteger>> map = new HashMap<BigInteger, List<BigInteger>>();
        for (Object[] result: results) {
            BigInteger fromId = (BigInteger) result[0];
            if (map.containsKey(fromId)) {
                map.get(fromId).add((BigInteger) result[1]);
            }
            else {
                List<BigInteger> neighbours = new ArrayList<BigInteger>();
                map.put(fromId, new ArrayList<BigInteger>(Arrays.asList(new BigInteger[]{(BigInteger) result[1]})));
            }
        }
        return map;
    }
}

• 您无法看到数据库中的更改，因为（在您使用的情况下）spring会在测试执行后清理事务。因此，测试方法内部的数据是可用的

• 使用sql脚本并不愚蠢，在许多情况下可能都适用

• 看看TestNG

我已经添加了webapplication contet，现在我可以通过perform（post（））和perform（delete）方法发布和删除数据，目前我还可以接受

  @Autowired
    private WebApplicationContext context;

    private JSONArray channels;
    @Before
    public void setup() throws Exception {
        mockMvc = MockMvcBuilders.webAppContextSetup(context).build();

你看过

@Sql

了吗？看，它是用于在测试期间以编程方式将数据插入数据库的。我不知道如何在你给出的最后一个链接中填充数据。但无论如何，我已经能够适当地构建mockmvc，以便导出资源，现在我实际上可以在测试前后发布和删除数据

  @Autowired
    private WebApplicationContext context;

    private JSONArray channels;
    @Before
    public void setup() throws Exception {
        mockMvc = MockMvcBuilders.webAppContextSetup(context).build();
