yaml解析

1、使用spring自带的yaml解析工具：

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

    public static Map<String, Object> yaml2Map(String yamlSource) {
        try {
            YamlMapFactoryBean yaml = new YamlMapFactoryBean();
            (new ClassPathResource(yamlSource));
            return ();
        } catch (Exception e) {
            ("Cannot read yaml", e);
            return null;
        }
    }

    public static Properties yaml2Properties(String yamlSource) {
        try {
            YamlPropertiesFactoryBean yaml = new YamlPropertiesFactoryBean();
            (new ClassPathResource(yamlSource));
            return ();
        } catch (Exception e) {
            ("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></groupId>
            <artifactId>snakeyaml</artifactId>
            <version>1.17</version>
        </dependency>

Yaml yaml = new Yaml();
LibraryPolicyDto libraryPolicyDto = (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<ApiDto> otherPublicApi;
    //getter
    //setter
}
