Springboot2.0加载指定配置文件@PropertySource的使用

1. 在resouces下编写待加载的配置文件

这里使用person.properties

# String
person.last-name=john
# int
person.age=112
# boolean
person.boss=false
# Date
person.birth=2019/11/12
# List<Object>
person.dogs[0].name=jj
person.dogs[0].age=111
person.dogs[1].name=tom
person.dogs[1].age=111
# Map<String, Object>
person.maps.Jack=jackc2
person.maps.Iris=yili8
person.maps.Panda=pandax
person.maps.Adun=gengwang
person.maps.Caedmon=chuankwa
# List
person.lists[0]=1
person.lists[1]=2
person.lists[2]=3
person.lists[3]=4
person.lists[4]=5

2. 在启动类中添加bean类@EnableConfigurationProperties

package cn.jfjb;

import cn.jfjb.bean.Person;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.EnableConfigurationProperties;


@SpringBootApplication
@EnableConfigurationProperties({Person.class})
public class SbHelloworld01QuickApplication {

    public static void main(String[] args) {
        SpringApplication.run(SbHelloworld01QuickApplication.class, args);
    }

}

3. 在bean中使用@PropertySource加载

package cn.jfjb.bean;

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.PropertySource;
import org.springframework.stereotype.Component;

import java.util.Date;
import java.util.List;
import java.util.Map;

/**
 * @author john
 * @date 2019/11/22 - 8:56
 */
@Component
@PropertySource("classpath:person.properties")
@ConfigurationProperties(prefix = "person")
public class Person {
    private String lastName;
    private Integer age;
    private boolean boss;
    private Date birth;
    private List<Dog> dogs;
    private Map<String, Object> maps;
    private List<Object> lists;

    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 List<Dog> getDogs() {
        return dogs;
    }

    public void setDogs(List<Dog> dogs) {
        this.dogs = dogs;
    }

    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;
    }

    @Override
    public String toString() {
        return "Person{" +
                "lastName='" + lastName + '\'' +
                ", age=" + age +
                ", boss=" + boss +
                ", birth=" + birth +
                ", dogs=" + dogs +
                ", maps=" + maps +
                ", lists=" + lists +
                '}';
    }
}
