是否有用于通用消息的mongodb映射转换器？没有参数构造函数不适用于通用消息。是否有用于通用消息的mongodb映射转换器

而且我想mongotemplate 的下列配置请告知，如果有3.0版本开始，建议使用ConfigurableMongoDbMessageStore为提供更多定制选项，包括一个Converter为Message正确

public MongoTemplate messagingMongoTemplate() throws Exception { 
    MongoTemplate mongoTemplate=null; 
    try { 
     DbRefResolver dbRefResolver = new DefaultDbRefResolver(mongoDbFactory); 
     MappingContext mappingContext = new MongoMappingContext(); 

     MappingMongoConverter mappingMongoConverter = new MappingMongoConverter(dbRefResolver,mappingContext); 

     CustomConversions customConversions = new CustomConversions(Arrays.asList(new MongoDbMessageBytesConverter())); 
     mappingMongoConverter.setCustomConversions(customConversions); 
     mongoTemplate=new MongoTemplate(mongoDbFactory,mappingMongoConverter);

。

出的即装即用Spring集成提供MongoDbMessageBytesConverter，因为4.2.10这已成为public并使用默认如果没有任何外部定制为ConfigurableMongoDbMessageStore。

感谢您的回应，但MongoDbMessageBytesConverter不是MappingMongoConverter。 – Adilmo

在问题中增加了stacktrace – Adilmo

这个MongoDbMessageBytesConverter是否需要用作变换器或者这可以绑定到mongodbfactory作为映射和变换器 – Adilmo
