springboot @PropertySource&@ImportResource

环境：使用person.properties文件

# person.properties使用在参数过多容易眼花，所以分类到不同文件
person.name=现在
person.isBooss=false
person.birthday=2019/8/06
person.map.k1=v1
。。。测试就设置所有参数了

一、 @PropertySource

@PropertySource(value = "classpath:person.properties")//可以读取到数据
@ConfigurationProperties(prefix = "person") //必须使用这个将数据映射到属性上
@Component
public class Person {
    
    

    private String name;
    private boolean isBooss;
    private Date birthday;
    private Map map;
    private List list;
    private Dog dog;

    @Value("#{10+20}")
    private int age;

    @Override
    public String toString() {
    
    
        return "Person{" +
                "name='" + name + '\'' +
                ", isBooss=" + isBooss +
                ", birthday=" + birthday +
                ", map=" + map +
                ", list=" + list +
                ", dog=" + dog +
                ", age=" + age +
                '}';
    }

    public String getName() {
    
    
        return name;
    }

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

    public Boolean getBooss() {
    
    
        return isBooss;
    }

    public void setBooss(Boolean booss) {
    
    
        isBooss = booss;
    }

    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 Dog getDog() {
    
    
        return dog;
    }

    public void setDog(Dog dog) {
    
    
        this.dog = dog;
    }
}

二、@ImportResource

①applicationContext.xml

<?xml version="1.0" encoding="UTF‐8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema‐instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring‐beans.xsd">

	<bean id="helloService" class="com.pringboot.service.HelloService"></bean>
</beans>

②代码

//导入Spring的配置文件让其生效，就是让配置文件信息让springboot读取
@ImportResource(locations = {
    
    "classpath:applicationContext.xml"})
@SpringBootApplication
public class SpringBootDemo01Application {
    
    

    public static void main(String[] args) {
    
    
        SpringApplication.run(SpringBootDemo01Application.class, args);
    }

}

三、@Configuration
