java解析yml文件为带注解的对象_java解析excel文件

YML文件格式是YAML (YAML Aint Markup Language)编写的文件格式，YAML是一种直观的能够被电脑识别的的数据数据序列化格式，并且容易被人类阅读，容易和脚本语言交互的，可以被支持YAML库的不同的编程语言程序导入，比如： C/C++, Ruby, Python, Java, Perl, C#, PHP等。以上来自网络解释，spring-boot可支持这种格式的配置文件，下面介绍如何自己在java中解析这种文件

如下test.yml文件

age: 418
name: Jack
params:
  event: what's up
  url:  http://www.test.com
favoriteBooks:
  - Gone with the wind
  - The Little Prince

public class TestEntity {
    private Integer age;
    private String name;
    private Map<String, Object> params;
    private List<String> favoriteBooks;

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Map<String, Object> getParams() {
        return params;
    }

    public void setParams(Map<String, Object> params) {
        this.params = params;
    }

    public List<String> getFavoriteBooks() {
        return favoriteBooks;
    }

    public void setFavoriteBooks(List<String> favoriteBooks) {
        this.favoriteBooks = favoriteBooks;
    }

    @Override
    public String toString() {
        return "TestEntity{" +
                "age=" + age +
                ", name='" + name + '\'' +
                ", params=" + params +
                ", favoriteBooks=" + favoriteBooks +
                '}';
    }
}

方式一：snakeyaml

maven依赖添加

 <dependency>
			<groupId>org.yaml</groupId>
			<artifactId>snakeyaml</artifactId>
			<version>1.10</version>
		</dependency>

java代码：

此代码由Java架构师必看网-架构君整理
@Test
	public void testYml() {
		org.yaml.snakeyaml.Yaml yaml = new org.yaml.snakeyaml.Yaml();
		TestEntity testEntity = yaml.loadAs(DemoApplicationTests.class.getResourceAsStream("/test.yml"), TestEntity.class);//如果读入Map,这里可以是Mapj接口,默认实现为LinkedHashMap
		System.out.println(testEntity);
	}

方式二：jyaml

maven依赖添加

 <dependency>
			<groupId>org.jyaml</groupId>
			<artifactId>jyaml</artifactId>
			<version>1.3</version>
		</dependency>

java代码：

@Test
	public void testJyml() {
		TestEntity testEntity = null;
		try {
			testEntity = org.ho.yaml.Yaml.loadType(DemoApplicationTests.class.getResourceAsStream("/test.yml"), TestEntity.class);//如果是读入Map,这里不可以写Ma接口，必须写实现
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		}
		System.out.println(testEntity);
	}

控制台输出：

TestEntity{age=418, name='Jack', params={event=what's up, url=http://www.test.com}, favoriteBooks=[Gone with the wind, The Little Prince]}
