springboot中的配置文件绑定

先创建一个peron类，然后需要注解configurationProperties（prefix ="person"）然后需要加一个@component因为只有在springboot的容器才能提供容器提供的@configurationProperties@Component
@ConfigurationProperties(prefix = "person")
public class Person {
	private String  lastName;
	private  Integer age;
	private boolean boss;
	private Date birth;
	private Map<String,Object> maps;
	private List<Object> lists;
	private Dog dog;
	public String getLastName() {
		return lastName;
	}
	public void setLastName(String lastName) {
		this.lastName = lastName;
	}
	public Integer getAge() {
		return age;
	}
	public void setAge(Integer age) {
		this.age = age;
	}
	public boolean isBoss() {
		return boss;
	}
	public void setBoss(boolean boss) {
		this.boss = boss;
	}
	public Date getBirth() {
		return birth;
	}
	public void setBirth(Date birth) {
		this.birth = birth;
	}
	public Map<String, Object> getMaps() {
		return maps;
	}
	public void setMaps(Map<String, Object> maps) {
		this.maps = maps;
	}
	public List<Object> getLists() {
		return lists;
	}
	public void setLists(List<Object> lists) {
		this.lists = lists;
	}
	public Dog getDog() {
		return dog;
	}
	public void setDog(Dog dog) {
		this.dog = dog;
	}
	@Override
	public String toString() {
		return "Person [lastName=" + lastName + ", age=" + age + ", boss=" + boss + ", birth=" + birth + ", maps="
				+ maps + ", lists=" + lists + ", dog=" + dog + "]";
	}

}

　　dog类

public class Dog {
	private String Name;
	private Integer age;
	public String getName() {
		return Name;
	}
	public void setName(String name) {
		Name = name;
	}
	public Integer getAge() {
		return age;
	}
	public void setAge(Integer age) {
		this.age = age;
	}
	@Override
	public String toString() {
		return "Dog [Name=" + Name + ", age=" + age + "]";
	}

}

写完后，ide会提示需要在pom.xml中导入组件处理器。

<!-- 配置文件的处理器 ,配置文件进行绑定就会有提示-->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-configuration-processor</artifactId>
			<optional>true</optional>
		</dependency>
	</dependencies>

　　然后创建配置文件，有两种方式，一个时yml文件，另一个时properties

1,application.yml

person:
  last-name: zhangsan
  age: 24
  boss: false
  birth: 2017/12/5
  maps: {k1: v1,k2: v2}
  lists: [lisi, zhangsan]
  dog:
  Name: xiaohei
  age: 4

2.application.properties

中文字，在eclipse中自动转为unicode码

person.age=24
person.last-name=\u5F20\u4E09
person.birth=2000/1/1
person.boss=false
person.maps.k1=value1
person.maps.k2=12
person.dog.name=\u5C0F\u9ED1
person.dog.age=2

　　在test中使用spring boot的单元测试

@RunWith(SpringRunner.class)
@SpringBootTest
class Helloworld01QuickApplicationTests {

	@Autowired
	Person person;

	@Test
	void contextLoads() {
		System.out.println(person);
	}

}

　　运行，会看到得到配置文件中的数据
