如何使用 groovy 编辑 ODI 中的现有映射

Question

我正在尝试弄清楚如何使用 groovy 来编辑现有映射。

我可以创建新的映射。我试图删除代码的删除部分，但它会给我一个错误，我需要删除现有映射

//delete old mapping
/* remove delete portion to use edit existing mapping
  removeMapping(folder, mappingName)

  txnDef = new DefaultTransactionDefinition()
  tm = odiInstance.getTransactionManager()
  tme = odiInstance.getTransactionalEntityManager()
  txnStatus = tm.getTransaction(txnDef)

  dsf = (IOdiDataStoreFinder)tme.getFinder(OdiDataStore.class)
  mapf = (IMappingFinder) tme.getFinder(Mapping.class)
*/
//create new mapping
  map = new Mapping(mappingName, folder);
  tme.persist(map)

从错误来看，似乎必须删除映射 (Load_TRG_CUSTOMER)。如果您需要更多代码，请告诉我。

错误：

ODI-16096: A mapping with name Load_TRG_CUSTOMER already exists in folder TEST_FOLDER.
(Subtract 18 from the error line number to account for the standard imports)
oracle.odi.domain.mapping.exception.MappingException: ODI-16096: A mapping with name Load_TRG_CUSTOMER already exists in folder TEST_FOLDER.
    at oracle.odi.domain.mapping.Mapping.checkName(Mapping.java:153)

感谢大家的帮助。

IMappingFinder provides useful methods to find an existing mapping. As you already know the name and folder, I guess that the findByName方法最适合你。

我看到您已经实例化了 IMappingFinder（尽管目前已对其进行评论）。所以你只需要替换 :

map = new Mapping(mappingName, folder);

来自

map = (Mapping) mapf.findByName(folder, mappingName);
