您需要为转换器config创建一个配置类。
@Configuration@EnableAutoConfiguration(exclude = { EmbeddedMongoAutoConfiguration.class })@Profile("!testing")public class MongoConfig extends AbstractMongoConfiguration { @Value("${spring.data.mongodb.host}") //if it is stored in application.yml, else hard pre it here private String host; @Value("${spring.data.mongodb.port}") private Integer port; @Override protected String getDatabaseName() { return "test"; } @Bean public Mongo mongo() throws Exception { return new MongoClient(host, port); } @Override public String getMappingbasePackage() { return "com.base.package"; } @Override public CustomConversions customConversions() { List<Converter<?, ?>> converters = new ArrayList<>(); converters.add(new LongToDateTimeConverter()); return new CustomConversions(converters); }}@ReadingConverterstatic class LongToDateTimeConverter implements Converter<Long, Date> { @Override public Date convert(Long source) { if (source == null) { return null; } return new Date(source); }}
