有人有什么想法吗?

解决方案

如果索引未正确进行，则可能会发生这种情况.您可以尝试按如下方式重新编制索引.

1. 备份位于/solr 中的 solr 文件夹并从 API Manager 主位置删除.
2. 打开/repository/conf/registry.xml
3. 在 indexingConfiguration 标签下有一个名为 lastAccessTimeLocation 的值.默认值为

<块引用>

/_system/local/repository/components/org.wso2.carbon.registry/indexing/lastaccesstime

将该值更改为

<块引用>

/_system/local/repository/components/org.wso2.carbon.registry/indexing/lastaccesstime1

4. 启动服务器.
5. 等待大约 2 分钟以进行索引.
6. 重新检查 API 的创建.

I have setup a new setup of WSO2 API Manager integrated with WSO2 Identity Server. When starting the WSO2 API Manager I start getting the following error:

Any one has any ideas please?

解决方案

This could happen if the indexing has not happened properly. You can try redoing the indexing as follows.

1. Backup the solr folder which resides in /solr and remove from API Manager home location.
2. Open /repository/conf/registry.xml
3. Under indexingConfiguration tag there is a value called lastAccessTimeLocation. Default value is

/_system/local/repository/components/org.wso2.carbon.registry/indexing/lastaccesstime

Change that value to

/_system/local/repository/components/org.wso2.carbon.registry/indexing/lastaccesstime1

4. Start the server.
5. Wait about 2 minutes for indexing.
6. Recheck the creation of the API.
