当我们在本地运行 Spring Boot 应用程序时，它可以正常工作，但是如果它部署在PCF，则会出现以下异常：

org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type [java.util.LinkedHashMap<?, ?>] to type [java.lang.String]

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如下：

@Configuration
public class SpringConvertors {

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