Question

我正在使用Apache Cayenne来存储数据并针对文件进行检查，以查看文件是否已更改。我目前有一种将数据插入数据库的方法，但正在接收：

Exception in thread "main" java.lang.IllegalArgumentException: Class is not mapped with Cayenne: edu.ndsu.eci.duo_demo.persist.Integrations
    at org.apache.cayenne.access.DataContext.newObject(DataContext.java:471)
    at edu.ndsu.eci.duo_demo.util.IntegrationService.insertData(IntegrationService.java:31)
    at edu.ndsu.eci.duo_demo.main.ServiceMain.main(ServiceMain.java:55)

我的方法：

public static void insertData(Integration i, ObjectContext context) {
    Integrations integ = context.newObject(Integrations.class);
    integ.setName(i.getName());
    integ.setEnrollPolicy(i.getEnrollPolicy());

    List<String> ipWhitelist = i.getIpWhitelist();
    String ip = "[";
    if(ipWhitelist.size() > 0)
      ip += "\"";
    for(int j = 0; j < ipWhitelist.size(); j++) {
      ip += ipWhitelist.get(j) + "\"";
      if(j < ipWhitelist.size()-1)
        ip += ",\"";
    }
    ip += "]";

    integ.setIpWhitelist(ip);
    context.commitChanges();
  }

修改

我的日志输出：

我的ServerRuntime的初始化：

ServerRuntime run = ServerRuntime.builder().addConfig("cayenne.xml").build();
ObjectContext context = run.getContext();

从启动日志中看，您有一个运行有较新运行时的旧“ cayenne.xml”文件：

if /?

IIRC tag <domains> is unexpected at [36,2]. The following tags are allowed here: [domain]是3.1之前的版本，而运行时看起来是3.1或4.0。所以我建议如下：

找出运行时使用的Cayenne版本。
下载此版本的Cayenne发行版。
使用发行版中的CayenneModeler应用程序打开“ cayenne.xml”文件。它应该询问您是否要升级。
继续升级。
很有可能该项目将从“ cayenne.xml”重命名为“ cayenne-project.xml”，因此请确认新名称是什么，并在创建<domains>时使用它

Apache Cayenne“类未与Cayenne映射”
