Solr配置数据列时大小写问题

鸦鸦

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;
Object o = aRow.get(srcCol);
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;
}

datetime的转换如下：

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 {
Object o = aRow.get(srcCol);
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;
}


从Object o = aRow.get(srcCol);可以看出，这些字段都是大小写敏感的了。
