我正在使用spring-data-rest 并尝试将PATCH请求发送到服务器，数据为长
所以有补丁
[{"op":"replace","path":"/serviceDate","value":1262304000000}]
我希望很长时间可以转换为java.util.date，但不是我得到
ConverterNotFoundExcepion找不到能够转换的转换器 从类型[java.lang.Long]到类型[java.util.Date]
我试图像这样注册自定义转换器
@Configuration
public class WebConfig extends WebMvcConfigurerAdapter {
@Override
public void addFormatters(FormatterRegistry registry) {
registry.addConverter(new LongToDateConverter());
}
}
甚至喜欢这个
@Configuration
public class ConverterServiceConfiguration {
@Bean(name="conversionService")
public ConversionService getConversionService() {
ConversionServiceFactoryBean bean = new ConversionServiceFactoryBean();
HashSet<Converter> converters = new HashSet<>();
converters.add(new LongToDateConverter());
bean.setConverters(converters);
bean.afterPropertiesSet();
ConversionService object = bean.getObject();
return object;
}
}
但没有任何事情发生。 我也在调试器中看到，用于从请求转换id（从字符串转换为Long）spring使用DefaultFormattingConvertionService（它有能力的转换器），但是对于转换值spring使用DefaultConversionService，这个类真的没有需要转换器，我已经注册了。 我怎样才能添加我的转换器，所以spring可以转换它？
这里是stacktrace
