尝试将JodaTime的LocalDate与Spring Data MongoDB和Spring 4一起使用,但我收到以下异常：
SEVERE: Servlet.service() for servlet [dispatcher] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.data.mapping.model.MappingException: No property node found on entity class com.th.model.Price to bind constructor parameter to!] with root cause

…
在这里我的配置：
public class MongoDBConverters {
public static class DateToLocalDateConverter implements Converter
最佳答案
显然我不能有这样的构造函数：
public Price(String companyId,JsonNode node) {
this.companyId = companyId;
if(node != null) {
this.date = Tools.getLocalDate(node.get("Date").getTextValue());
this.closePrice = Double.parseDouble(node.get("Close").getTextValue());
this.volume = Double.parseDouble(node.get("Volume").getTextValue());
}
}
具有直接分配工作的正常工作：
public Price(String companyId,LocalDate date,double closePrice,double volume) {
this.companyId = companyId;
this.date = date;
this.closePrice = closePrice;
this.volume = volume;
}
