Spring数据MongoDB导致IllegalArgumentException：不受支持的实体无法确定IsNewStrategy

Question

我将spring data mongodb（使用maven）版本升级到1.9.5。释放。（使用MongoClient而不是Mongo）。我的会话文档类包含@LastModifiedDate注释。

升级后，我得到了java。lang.IllegalArgumentException：不支持的实体com。。。一场无法确定IsNewStrategy。

如果我从配置中删除，我不会得到错误，但它不会保存modifiedDate。我找到的所有解决方案都与使用注释而不是xml文件的MongoDB配置相关。我如何解决这个问题？

Maven依赖项：

<dependency>
	<groupId>org.springframework.data</groupId>
	<artifactId>spring-data-mongodb</artifactId>
	<version>1.9.5.RELEASE</version>
</dependency>
<dependency>
    <groupId>joda-time</groupId>
    <artifactId>joda-time</artifactId>
    <version>2.9.5</version>
</dependency>

Spring MongoDB配置包含：

我的文档：

package com.....session;

import java.util.Date;
import java.util.UUID;
import org.joda.time.DateTime;
import org.springframework.data.annotation.Id;
import org.springframework.data.annotation.LastModifiedDate;

@Document(collection = "session")
public class Session {

	@Id
	protected UUID id;
	private DateTime creationDate;
	@LastModifiedDate
	private DateTime modifiedDate;

	public Session() {}
	
	//setters & getters	
}

诀窍是在审核和MongoTemplate之间共享MongoMappingContext。

第一次替换：

<mongo:auditing/>

与：

<bean id="mappingContext" class="org.springframework.data.mongodb.core.mapping.MongoMappingContext" />
<mongo:auditing mapping-context-ref="mappingContext"/>

然后将MongoDbFactory和MongoConverter添加到您的xml设置中，如下所示：

<mongo:db-factory id="mongoDbFactory" mongo-ref="mongo" dbname="${dbName}"/>
<mongo:mapping-converter id="mongoConverter" db-factory-ref="mongoDbFactory" mapping-context-ref="mappingContext"/> 

最后要做的是将MongoConverter注入模板。它为MongoTemboard提供映射上下文。您必须为此使用替代构造函数。

替换：

<constructor-arg name="mongo" ref="mongo" />
<constructor-arg name="databaseName" value="${dbName}"/>    

与：

<constructor-arg name="mongoDbFactory" ref="mongoDbFactory"/>
<constructor-arg name="mongoConverter" ref="mongoConverter"/>
