SpringBoot复习：（5）使用PropertySource注解

一、自定义的一个配置文件

age=33
name=liu

二、实体类

package com.example.demo.domain;public class Student {private String name;private int age;public String getName() {return name;}public void setName(String name) {this.name = name;}public int getAge() {return age;}public void setAge(int age) {this.age = age;}
}

三、配置类中使用@PropertySource注解

package com.example.demo.config;import com.example.demo.domain.Student;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.core.env.Environment;@Configuration
@PropertySource("classpath:my.properties")
public class MyConfig {@Autowiredprivate Environment environment;@Bean("student")public Student getStudent(){Student student = new Student();student.setAge(Integer.parseInt( environment.getProperty("age")));student.setName(environment.getProperty("name"));return student;}
}
