SpringBoot 单元测试问题

SpringBoot 里的单元测试,先贴个代码：

@Test
@Transactional
@Rollback(true)
public void addChildResourceTest() {
    JSONObject requestBody = new JSONObject();
    requestBody.accumulate("userId", "admin");
    requestBody.accumulate("parentId", "901BCDCA-B272-4F52-B1F0-E47603771611");

    JSONArray childResourceList = new JSONArray();
    JSONObject child = new JSONObject();
    child.accumulate("id", "505BCDCA-B272-5F52-B1F0-E57603771611");
    child.accumulate("name", "测试子资源");
    child.accumulate("index", 0);
    child.accumulate("oriResourceId", "6728353b-f448-11e7-8bf7-00155dbc9610");
    JSONObject metadata = new JSONObject();
    metadata.accumulate("时间", "2018-01-05 11:50:33");
    child.accumulate("metadata", metadata);
    child.accumulate("description", "描述");
    childResourceList.add(child);
    requestBody.accumulate("childReourceList", childResourceList);

    try {
        MvcResult updateResult = mockMvc.perform(MockMvcRequestBuilders.post("/api/resource/child").content(requestBody.toString())).andReturn();
        int updateStatus = updateResult.getResponse().getStatus();
        Assert.assertEquals("success", 200, updateStatus);
    } catch (Exception e) {
        e.printStackTrace();
    }

}


各位大佬，这种 controller 层的单元测试支持回滚吗？测试过程中感觉一会回滚一会又不回滚。。。
