如何将新数据库添加到cTAKES管道以执行查找？如何指定要查找的列以及如何使用返回的匹配对文本进行注释？我已经浏览了DictionaryLookupAnnotatorDB.xml和LookupDesc_Db.xml文件.但是,我无法理解"lookupField","metaField","maxPermutationLevel"和"exclusionTags"等术语的含义.如果我添加新数据库,我需要正确配置此xml文件.请指导我这些问题.

我通过DTO从我的表单中获取数据并将其映射到我的Hibernate实体.我想跳过一个日期字段,因为传入的数据是所有字符串,我需要将字符串字段转换为与其他字段分开的日期.其余字段将从传入的DTO直接映射.该过程适用于第一个请求,但在后续请求中,抛出以下异常:

     1) A mapping already exists for com.ibm.calypso.entity.WmCompIdfn.setEffStartDate().

这个问题已在此处针对 Scala提出，在我使用 Java API 时它对我没有帮助。我真的把所有东西和厨房水槽都扔了，所以这是我的方法：

List<String> sourceClasses = new ArrayList<String>();
//Add elements
List<String> targetClasses = new ArrayList<String>();
//Add elements

dataset = dataset.withColumn("Transformer", callUDF(
    "Transformer",
    lit((String[])sourceClasses.toArray())
        .cast(DataTypes.createArrayType(DataTypes.StringType)),
    lit((String[])targetClasses.toArray())
        .cast(DataTypes.createArrayType(DataTypes.StringType))
));

对于我的 UDF 声明：

public class Transformer implements UDF2<Seq<String>, Seq<String>, String> {


//  @SuppressWarnings("deprecation")
public String call(Seq<String> sourceClasses, Seq<String> targetClasses)
    throws Exception {

当我运行代码时，执行不会通过 UDF 调用，这是意料之中的，因为我无法匹配类型。请在这方面帮助我。

我尝试了@Oli 建议的解决方案。但是，我得到以下异常：
