Spring Boot应用程序在我们本地运行时工作正常,但如果它部署在PCF中,则低于异常:

答案 0 :(得分:0)

您可以按如下方式创建自定义转换器:

@Component
public class LinkedHashMap2String implements Converter<LinkedHashMap, String> {

    @Override
    public String convert(LinkedHashMap source) {
        return source.toString();
    }
}

然后将此转换器添加到GenericConversionList中,如下所示:

@Configuration
public class SpringConvertors {

    @Bean
    public ConversionService conversionService(LinkedHashMap2String linkedHashMap2String) {
        ConversionServiceFactoryBean conversionServiceFactory = new ConversionServiceFactoryBean();
        conversionServiceFactory.setConverters(Sets.newHashSet(linkedHashMap2String);
        conversionServiceFactory.afterPropertiesSet();
        return conversionServiceFactory.getObject();
    }
}
