Spring integration 是否有用于通用消息的mongodb映射转换器

是否存在用于通用消息的mongodb映射转换器。 无参数构造函数不适用于泛型消息

从版本

3.0

开始，建议使用

ConfigurableMongoDbMessageStore

，因为它提供了更多自定义选项，包括用于

消息的
转换器

现成的Spring集成提供了
MongoDbMessageBytesConverter
，自
4.2.10
以来，它已成为
public
，如果
ConfigurableMongoDbMessageStore
没有任何外部自定义，则默认情况下使用它。感谢您的回答，但MongoDbMessageBytesConverter不是映射MongoConverter。问题中添加了stacktrace此MongoDbMessageBytesConverter是否需要作为转换器使用，或者可以作为映射MongoConverterMappingContext mappingContext=new MongoMappingContext（）绑定到mongodbfactory；MappingMongoConverter MappingMongoConverter=新的MappingMongoConverter（dbRefResolver，mappingContext）；CustomConversions CustomConversions=新的CustomConversions（Arrays.asList（new MongoDbMessageBytesConverter（））；mappingMongoConverter.setCustomConversions（customConversions）；mongoTemplate=新的mongoTemplate（mongoDbFactory、mappingMongoConverter）；是的，最后一个是正确的。有关映射的更多信息，请查看SpringDataMongoDB
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);
