Yaml parsing using com.fasterxml.jackson

Question

I am trying to parse yaml files in models using jackson

Model -

public class TestModel { private String name; public String getName() { return name; } public void setName(String name) { this.name = name; } } 

Syntactic

 private static ObjectMapper mapper = new ObjectMapper(new YAMLFactory()); TestModel obj = mapper.readValue(yamlFile, TestModel.class); 

Yaml file

 name: somename 

Exception

 Caused by: com.fasterxml.jackson.core.JsonParseException: Unrecognized token 'name': was expecting 'null', 'true', 'false' or NaN [error] at [Source: /Users/amruth.s/Documents/Analytics/hydra/reportManager/target/scala-2.9.1/classes/viz/LineGraph.yaml; line: 1, column: 6] [error] at com.fasterxml.jackson.core.JsonParser._constructError(JsonParser.java:1369) [error] at com.fasterxml.jackson.core.base.ParserMinimalBase._reportError(ParserMinimalBase.java:599) [error] at com.fasterxml.jackson.core.json.UTF8StreamJsonParser._reportInvalidToken(UTF8StreamJsonParser.java:2449) [error] at com.fasterxml.jackson.core.json.UTF8StreamJsonParser._reportInvalidToken(UTF8StreamJsonParser.java:2426) [error] at com.fasterxml.jackson.core.json.UTF8StreamJsonParser._matchToken(UTF8StreamJsonParser.java:2403) [error] at com.fasterxml.jackson.core.json.UTF8StreamJsonParser._nextTokenNotInObject(UTF8StreamJsonParser.java:760) [error] at com.fasterxml.jackson.core.json.UTF8StreamJsonParser.nextToken(UTF8StreamJsonParser.java:665) [error] at com.fasterxml.jackson.databind.ObjectMapper._initForReading(ObjectMapper.java:2926) [error] at com.fasterxml.jackson.databind.ObjectMapper._readMapAndClose(ObjectMapper.java:2873) [error] at com.fasterxml.jackson.databind.ObjectMapper.readValue(ObjectMapper.java:1988) [error] at com.flipkart.hydra.util.YAMLUtil.toObject(YAMLUtil.java:29)

Try updating jackson-dataformat-yaml version. I ran into the same issue until I updated the version of my dependency on Maven.

My dependency is as follows:

 <dependency> <groupId>com.fasterxml.jackson.dataformat</groupId> <artifactId>jackson-dataformat-yaml</artifactId> <version>2.1.3</version> </dependency>
