@PropertySource加载局部配置文件

@ConfigurationProperties 默认从全局配置文件(application.properties/application.yml)中获取值,
所有配置数据写在全局配置文件中，显得太臃肿了, 可将它们抽取出来，放到其他局部配置文件中

1. 将 全局配置文件 中的emp相关配置数据 抽取 到 resources/ emp.properties 文件中

2. @PropertySource ：加载指定的配置文件; value 属性是数组类型, 用于指定文件位置

@PropertySource(value = {"classpath:emp.properties"})
@Component
public class Emp {
    private String lastName;
    private Integer age;
    private Double salary;
    private Boolean boss;
    private Date birthday;
    private Map map;
    private List list;
    private Forte forte;
    @Override
    public String toString() {
        return "Emp{" +
                "lastName='" + lastName + '\'' +
                ", age=" + age +
                ", salary=" + salary +
                ", boss=" + boss +
                ", birthday=" + birthday +
                ", map=" + map +
                ", list=" + list +
                ", forte=" + forte +
                '}';
    }

    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 Double getSalary() {
        return salary;
    }

    public void setSalary(Double salary) {
        this.salary = salary;
    }

    public Boolean getBoss() {
        return boss;
    }

    public void setBoss(Boolean boss) {
        this.boss = boss;
    }

    public Date getBirthday() {
        return birthday;
    }

    public void setBirthday(Date birthday) {
        this.birthday = birthday;
    }

    public Map getMap() {
        return map;
    }

    public void setMap(Map map) {
        this.map = map;
    }

    public List getList() {
        return list;
    }

    public void setList(List list) {
        this.list = list;
    }

    public Forte getForte() {
        return forte;
    }

    public void setForte(Forte forte) {
        this.forte = forte;
    }
}
