yaml解析

1、使用spring自带的yaml解析工具:

public class YamlUtils {
    private static final Logger logger = LogManager.getLogger(YamlUtils.class);

    public static Map yaml2Map(String yamlSource) {
        try {
            YamlMapFactoryBean yaml = new YamlMapFactoryBean();
            yaml.setResources(new ClassPathResource(yamlSource));
            return yaml.getObject();
        } catch (Exception e) {
            logger.error("Cannot read yaml", e);
            return null;
        }
    }

    public static Properties yaml2Properties(String yamlSource) {
        try {
            YamlPropertiesFactoryBean yaml = new YamlPropertiesFactoryBean();
            yaml.setResources(new ClassPathResource(yamlSource));
            return yaml.getObject();
        } catch (Exception e) {
            logger.error("Cannot read yaml", e);
            return null;
        }
    }
}

spring提供的yaml工具只能够解析出map和properties,如果想解析生成java bean就有点力不从心,不方便。
2、使用snakeyaml
在maven中引入

<dependency>
            <groupId>org.yamlgroupId>
            <artifactId>snakeyamlartifactId>
            <version>1.17version>
        dependency>
Yaml yaml = new Yaml();
LibraryPolicyDto libraryPolicyDto = yaml.loadAs(inputStream, LibraryPolicyDto.class);

打完收工。。。
附yaml文件:

systemLibraryId: 1
relativeLibraryId: xxx
readerPolicyIndex: 1
bookPolicyIndex: 1
otherPublicApi:
-
name: showApi
desc: 查看api
url: 127.0.0.1:8080/api/showApi
port: 8080
inputParams:
- id:int
- libraryId:String
outputParams:
- name:String
- desc:String
- url:String
- inputParams:String
- ouputParams:String

附LibraryPolicyDto

public class LibraryPolicyDto {
    private int systemLibraryId;
    private String relativeLibraryId;
    private int readerPolicyIndex;
    private int bookPolicyIndex;
    private List otherPublicApi;
    //getter
    //setter
}
