Spring Data MongoDB的Java 8日期/时间（JSR-310）类型映射

我不知道这是否是最好的方法，但是我向Spring Data MongoDB添加了Java 8 Date /
Time（JSR-310）类型支持，

1.5.0.RELEASE

1. 第一步。添加简单的Spring

   Converter

   小号

        public class InstantToLongConverter implements Converter<Instant, Long> {        @Override        public Long convert(Instant instant) { return instant.toEpochMilli();        }    }    public class LongToInstantConverter implements Converter<Long, Instant> {        @Override        public Instant convert(Long source) { return Instant.ofEpochMilli(source);        }    }    public class LocalDateToStringConverter implements Converter<LocalDate, String> {        @Override        public String convert(LocalDate localDate) { return localDate.toString();        }    }    public class StringToLocalDateConverter implements Converter<String, LocalDate> {        @Override        public LocalDate convert(String source) { return LocalDate.parse(source);        }    }

1. 第二步。注册这些自定义的

   Converter

   与S

   MappingMongoConverter

   在

   AbstractMongoConfiguration

   实现这样的：

        @Configuration    @EnableMongoRepositories(basePackages = {"my.app.repository"})    public class MongoConfiguration extends AbstractMongoConfiguration {        ...        @Override        public CustomConversions customConversions() { return new CustomConversions(Arrays.asList(         new InstantToLongConverter(), new LongToInstantConverter(),         new LocalDateToStringConverter(), new StringToLocalDateConverter()));        }    }

现在，您文档的

Instant

LocalDate
