Spring Boot-@PropertySource注解

@PropertySource：加载自己手动编写的资源文件
有关@ConfigurationProperties注解的作用请访问Spring Boot-@Value获取值和@ConfigurationProperties获取值的比较

//@Component：将组件注入到容器中
@PropertySource(value = {"classpath:person.properties"})
@Component
@ConfigurationProperties(prefix = "person")
public class Person {

    private String lastName;
    private Integer age;
    private Boolean boss;
    private Date date;


    private Map<String,Object> map;

    private List<Object> list;

    private Student student;

    public Student getStudent() {
        return student;
    }

    public void setStudent(Student student) {
        this.student = student;
    }

person.properties

person.last-name=李四
person.age=20
person.date=2000/10/10
person.boss=false
person.map.k1=v1
person.map.k2=v2
person.list=a,b,c
person.student.name=lisi
person.student.age=13

测试

@SpringBootTest
class SpringBoot02ApplicationTests {

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

}

结果：
