SpringData MongoDB 在审计期间无法确定 IsNewStrategy [英] SpringData MongoDB cannot determine IsNewStrategy during Auditing

问题描述

我正在尝试使用注释启用审计.我的域类具有在构造对象时填充的 @Id 字段.我为 lastModified 添加了一个 java.util.Date 字段，并用 @LastModifiedDate 对其进行了注释.

I am trying to enable Auditing using Annotations. My domain class has @Id field that is populated while constructing the object. I have added a java.util.Date field for lastModified and annotated it with @LastModifiedDate.

@Document
public class Book {
    @Id
    private String name;
    private String isbn;
    @LastModifiedDate
    private Date lastModified;

    public Book(String name) {
        this.name = name;
    }
}

我使用 .

当我尝试保存对象的实例时，出现以下错误:

When I try to save an instance of my object, I get the following error:

Book book1 = new Book("ABCD");
mongoOps.save(book1);

java.lang.IllegalArgumentException:不支持实体 com.pankaj.Book！无法确定 IsNewStrategy.

java.lang.IllegalArgumentException: Unsupported entity com.pankaj.Book! Could not determine IsNewStrategy.

我不想使用 Auditable 接口，也不想从 AbstractAuditable 扩展我的域类.我只想使用注释.因为我对@CreatedBy 和@LastModifiedBy 不感兴趣，所以我也没有实现AuditAware 接口.

I do not want to use the Auditable interface nor extend my domain classes from AbstractAuditable. I only want to use the Annotations. Since I am not interested in the @CreatedBy and the @LastModifiedBy, I am not implementing the AuditAware interface as well.

我只希望 @LastModifiedDate 为我的域类工作.我错过了什么?

I just want the @LastModifiedDate to work for my domain classes. What am I missing?

我使用的是 SpringData MongoDB 1.7.0 版.

I am using version 1.7.0 of SpringData MongoDB.

推荐答案

你没有提到你是如何配置你的 MongoDB 连接的，但是如果你使用的是 AbstractMongoConfiguration，它将使用实际配置类的包来寻找@在启动时记录带注释的类.

You don't mention how you are configuring your MongoDB connection but if you are using AbstractMongoConfiguration, it will use the package of the actual configuration class to look for @Document annotated classes at startup.

如果您的实体在不同的包中，您将必须通过覆盖 AbstractMongoConfiguration.getMappingBasePackage() 手动处理该包.将它放在您的 Mongo Configuration 类中应该可以解决问题(同样，这是考虑到您正在为您的 Mongo 配置扩展 AbstractMongoConfiguration):

If your entities are in a different package, you will have to manually hand that package by overriding AbstractMongoConfiguration.getMappingBasePackage(). Placing this in you Mongo Configuration class should do the trick (again, this is considering you are extending AbstractMongoConfiguration for your Mongo configuration):

@Override
protected String getMappingBasePackage() {
    return "package.with.my.domain.classes";
}
