本文介绍了解决在Spring框架中遇到的ConverterNotFoundException异常的方法。该异常通常发生在从Joda-Time的LocalDate类型转换到字符串类型时。通过创建并配置自定义的MappingMongoConverter实例，可以有效地解决此问题。

①，org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type org.joda.time.LocalDate to type java.lang.String
at org.springframework.core.convert.support.GenericConversionService.handleConverterNotFound(GenericConversionService.java:475)
at org.springframework.core.convert.support.GenericConversionService.convert(GenericConversionService.java:175)

at org.springframework.core.convert.support.GenericConversionService.convert(GenericConversionService.java:154)

解决方案：converter.afterPropertiesSet();

MappingMongoConverter converter = new MappingMongoConverter(mongoDbFactory, context);
converter.setTypeMapper(mapper);
converter.setCustomConversions(new CustomConversions(Arrays.asList(new TimeZoneReadConverter(),new TimeZoneWriteConverter())));
converter.afterPropertiesSet();
MongoTemplate template = new MongoTemplate(mongoDbFactory, converter);
