I've hit the similar problem as described here: MappingInstantiationException with a BigInteger field in Spring Data Couchbase , so I've tried to workaround the problem with solution suggested by @Simon Baslé. I've added following custom converters:
@Configuration
@EnableCouchbaseRepositories
@EnableCouchbaseAuditing
public class CouchbaseConfig extends AbstractCouchbaseConfiguration {
(...)
@Override
public CouchbaseCustomConversions customConversions() {
return new CouchbaseCustomConversions(
Arrays.asList(BigDecimalToStringConverter.INSTANCE,
StringToBigDecimalConverter.INSTANCE));
}
@WritingConverter
enum BigDecimalToStringConverter implements Converter<BigDecimal, String> {
INSTANCE;
@Override
public String convert(BigDecimal source) {
return source == null ? null : source.toString();
}
}
@ReadingConverter
enum StringToBigDecimalConverter implements Converter<String, BigDecimal> {
INSTANCE;
@Override
public BigDecimal convert(String source) {
return StringUtils.isNotEmpty(source) ? new BigDecimal(source) : null;
}
}
}
But after applying this solution I am getting next exception:
org.springframework.data.mapping.MappingException: Couldn't find PersistentEntity for type java.math.BigDecimal!
