Solr配置数据列时大小写问题
在solr里配置entity时，没有把field里column的大小写配成和数据库的schema一致，导致有些列的数据一直取不出来，检查好多遍才发现，多花了两个小时。
主要是习惯了hibernate里配置列名时的大小写不敏感。
看了下源码，数据库里复杂类型如datetime,clob列的转换是继承了Transformer类，实现transformRow方法完成的，如Clob字段的转换如下:
public Object transformRow(Map<String, Object> aRow, Context context) { for (Map<String, String> map : context.getAllEntityFields()) { if (!TRUE.equals(map.get(CLOB))) continue; String column = map.get(DataImporter.COLUMN); String srcCol = map.get(RegexTransformer.SRC_COL_NAME); if (srcCol == null) srcCol = column; [b]Object o = aRow.get(srcCol);[/b] if (o instanceof List) { List<Clob> inputs = (List<Clob>) o; List<String> results = new ArrayList<String>(); for (Object input : inputs) { if (input instanceof Clob) { Clob clob = (Clob) input; results.add(readFromClob(clob)); } } aRow.put(column, results); } else { if (o instanceof Clob) { Clob clob = (Clob) o; aRow.put(column, readFromClob(clob)); } } } return aRow; }public Object transformRow(Map<String, Object> aRow, Context context) { for (Map<String, String> map : context.getAllEntityFields()) { Locale locale = Locale.getDefault(); String customLocale = map.get("locale"); if(customLocale != null){ locale = new Locale(customLocale); } String fmt = map.get(DATE_TIME_FMT); if (fmt == null) continue; String column = map.get(DataImporter.COLUMN); String srcCol = map.get(RegexTransformer.SRC_COL_NAME); if (srcCol == null) srcCol = column; try { [b]Object o = aRow.get(srcCol);[/b] if (o instanceof List) { List inputs = (List) o; List<Date> results = new ArrayList<Date>(); for (Object input : inputs) { results.add(process(input, fmt, locale)); } aRow.put(column, results); } else { if (o != null) { aRow.put(column, process(o, fmt, locale)); } } } catch (ParseException e) { LOG.warn("Could not parse a Date field ", e); } } return aRow; }
