java - 映射异常 : "No property found on entity to bind constructor parameter to"?

Question

我的项目是用spring data mongodb开发的，以前有这个文档:

@Document(collection="Instrument")
public class Instrument {
@Id
private Integer id;

private String name;

private String internalCode;

private String fosMarketId;

private String localCode;

//setters...getters... and constructurs....

现在我需要向我的文档添加一些属性，如下所示:

....

private Long from;

private Long to;

private Long OpenHourfrom;

private Long OpenHourTo;

private Boolean isActive;

//setters...getters... and constructurs....

所以我有了这个新的构造函数:

    @PersistenceConstructor
public Instrument(Integer id, String name, String internalCode, String fosMarketId, String localCode, Long from,
        Long to, Long openHourfrom, Long openHourTo, Boolean isActive) {
    super();
    this.id = id;
    this.name = name;
    this.internalCode = internalCode;
    this.fosMarketId = fosMarketId;
    this.localCode = localCode;
    this.from = from;
    this.to = to;
    this.OpenHourfrom = openHourfrom;
    this.OpenHourTo = openHourTo;
    this.isActive = isActive;
}

但是当我运行其中一个 repo 方法时，这个异常被抛出:

org.springframework.data.mapping.model.MappingException: No property openHourfrom found on entity class com.tosan.entity.Instrument to bind constructor parameter to!
at org.springframework.data.mapping.model.PersistentEntityParameterValueProvider.getParameterValue(PersistentEntityParameterValueProvider.java:74)
at ....

请注意，我使用带有以下设置的 spring-confix.xml:

    <mongo:mongo-client 
    host="IP" port="Port"  >
<mongo:client-options write-concern="NORMAL" 
            connections-per-host="1000"
                threads-allowed-to-block-for-connection-multiplier="600"
                connect-timeout="10000"
                max-wait-time="15000"                   
                socket-keep-alive="true"
                socket-timeout="15000"
    />
</mongo:mongo-client>

我想知道如何将 hibernate spring 的自动更新属性设置为 true，以便我可以更新我的文档并添加新属性。

Answer 1

1. 使用import org.springframework.data.mongodb.core.mapping.Field;@Field 每个字段的注释

2. 检查实体类的构造函数并确保参数名称正确
