Spring Cloud Openfeign Deserializing String is failing

Hi,

I am using spring cloud feign. I invoke an end point that returns String. I have configured jacksondecoder in my feign interface. I see that the end point is being successfully hit and it returns String value. However, the decoder fails to decode with the following exception. Can some one please help?

Exception in thread "main" com.fasterxml.jackson.core.JsonParseException: Unrecognized token 'test': was expecting 'null', 'true', 'false' or NaN at [Source: (StringReader); line: 1, column: 9] at com.fasterxml.jackson.core.JsonParser._constructError(JsonParser.java:1804) at com.fasterxml.jackson.core.base.ParserMinimalBase._reportError(ParserMinimalBase.java:703) at com.fasterxml.jackson.core.json.ReaderBasedJsonParser._reportInvalidToken(ReaderBasedJsonParser.java:2853) at com.fasterxml.jackson.core.json.ReaderBasedJsonParser._reportInvalidToken(ReaderBasedJsonParser.java:2831) at com.fasterxml.jackson.core.json.ReaderBasedJsonParser._matchToken2(ReaderBasedJsonParser.java:2628) at com.fasterxml.jackson.core.json.ReaderBasedJsonParser._matchToken(ReaderBasedJsonParser.java:2606) at com.fasterxml.jackson.core.json.ReaderBasedJsonParser._matchTrue(ReaderBasedJsonParser.java:2564) at com.fasterxml.jackson.core.json.ReaderBasedJsonParser.nextToken(ReaderBasedJsonParser.java:725) at com.fasterxml.jackson.databind.ObjectMapper._initForReading(ObjectMapper.java:4141) at com.fasterxml.jackson.databind.ObjectMapper._readMapAndClose(ObjectMapper.java:4000) at com.fasterxml.jackson.databind.ObjectMapper.readValue(ObjectMapper.java:3063) at com.feign.orch.Test.main(Test.java:16)

I am using the feign client to connect to rest easy end points hosted in jboss. I have configured my feign in a separate class as shown below

`public class JAXRSFeignConfig {

public JAXRSFeignConfig() {
}

@Bean
@DependsOn("objectMapper")
public Decoder feignDecoder(ObjectMapper objectMapper) {
    return new JacksonDecoder(objectMapper);
}

@Bean
@DependsOn("objectMapper")
public Encoder feignEncoder(ObjectMapper objectMapper) {
    return new JacksonEncoder(objectMapper);
}

@Bean
public Contract feignContract() {
    return new JAXRSContract();
}

@Bean
public ObjectMapper objectMapper() {
    ObjectMapper objectMapper = new ObjectMapper();
    objectMapper.findAndRegisterModules();
    objectMapper.setPropertyNamingStrategy(PropertyNamingStrategy.SNAKE_CASE);
    objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
    objectMapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);
    return objectMapper;
}

}`
