我正在使用杰克逊yaml解析器jackson-dataformat-yaml
来解析YAML文件,但无法解析以下YAML文件。
environments:
linux:
- [rbenv,python-2.7]
env:
global:
# The username below should have write access to your module repository, to automatically commit new version tags.
- USERNAME=sdfasfaf
- secure: "fadfasdf"
build: |
set -o errexit
set -o nounset
#./bootstrap_factory_utils
解析- USERNAME=sdfasfaf
属性时遇到问题。以下是代表YAML文件的pojo类。
SFYaml.java:
public class SFYaml {
private Environments environments;
private Env env;
private String build;
}
Env.java:
public class Env {
private Global[] global;
}
Global.java:
public class Global {
private String secure;
}
解析yaml文件的方法:
public String readYaml() {
YAMLFactory yamlFactory = new YAMLFactory();
YAMLMapper yMapper = new YAMLMapper(yamlFactory);
yMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
String output = "";
try {
SFYaml sfYaml = yMapper.readValue(new File(yamlPath), SFYaml.class);
output = yMapper.writeValueAsString(sfYaml);
log.info(sfYaml.getPublish());
// log.info(output);
} catch (JsonProcessingException e1) {
e1.printStackTrace();
} catch (IOException e2) {
// TODO Auto-generated catch block
e2.printStackTrace();
}
return output;
}
我尝试添加@JsonProperty
批注@JsonIgnoreProperties(ignoreUnknown = true)
,并尝试了各种DeserializationFeature
功能来禁用解析失败,但是我总是遇到以下错误。
com.fasterxml.jackson.databind.exc.MismatchedInputException:无法 构造

的实例(尽管 至少存在一个创建者):没有字符串参数构造函数/工厂 从字符串值('USERNAME = sdfasfaf')反序列化的方法 [源文件);行:12,列:7](通过参考链: com.amadeus.bitbucket.pojos.SFYaml [“ env”]-> com.amadeus.bitbucket.pojos.Env [“ global”]-> java.lang.Object [] [0]) 在 com.fasterxml.jackson.databind.exc.MismatchedInputException.from(MismatchedInputException.java:63) 在 com.fasterxml.jackson.databind.DeserializationContext.reportInputMismatch(DeserializationContext.java:1342) 在 com.fasterxml.jackson.databind.DeserializationContext.handleMissingInstantiator(DeserializationContext.java:1031) 在 com.fasterxml.jackson.databind.deser.ValueInstantiator._createFromStringFallbacks(ValueInstantiator.java:371) 在 com.fasterxml.jackson.databind.deser.std.StdValueInstantiator.createFromString(StdValueInstantiator.java:323)
如何解析此USERNAME=sdfasfaf
属性?还是使用任何变通办法?
