Jackrabbit Oak 合并不保存更改

Question

我刚开始研究 Jackrabbit Oak 1.7.5，但无法保存我的更改 - 此测试在最后一个断言上失败：

public class JCRTest {

@Test
public void testCommit() throws CommitFailedException {
    final NodeStore ns = new MemoryNodeStore();
    final String imagesFolder = "images";
    NodeState rootState = ns.getRoot();

    //newly created store does not have nodes
    assertThat(rootState.getChildNode(imagesFolder).exists(), is(equalTo(false)));

    NodeBuilder rootBuilder = rootState.builder();
    //adding a node called 'images'
    rootBuilder.child(imagesFolder);

    //it is still not going to be shown since we are working in our own 'state'
    assertThat(rootState.getChildNode(imagesFolder).exists(), is(equalTo(false)));

    //merging the changes into root
    ns.merge(rootBuilder, EmptyHook.INSTANCE, CommitInfo.EMPTY);

    //expecting to see the 'images' folder
    assertThat(rootState.getChildNode(imagesFolder).exists(), is(equalTo(true)));
}
}

Answer 1

A NodeState（测试中的 rootState）是存储库的快照。合并更改后，您需要再次获取存储库的负责人（即在断言之前再次执行 rootState = ns.getRoot()）。
