person.properties

person.name=小明
    person.age=22
    person.birth=2019/01/01
    person.stage=true
    person.maps.name=jack
    person.maps.age=16
    person.lists=a,b
    person.child.name=露西
    person.child.age=11

测试：

import com.atguigu.springboot.pojo.Person;
    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.boot.test.context.SpringBootTest;
    import org.springframework.context.ApplicationContext;
    import org.springframework.test.context.junit4.SpringRunner;
    
    import javax.annotation.Resource;
    
    @RunWith(SpringRunner.class)
    @SpringBootTest
    public class SpringBoot01HelloworldApplicationTests {
    
    	@Autowired
    	private Person person;
    
    	@Test
    	public void contextLoads() {
    		System.out.println(person.toString());
    	}
    
    
    }

结果：

> Person\{name='小明', age=22, stage=true, birth=Tue Jan 01 00:00:00 CST 2019, maps=\{age=16, name=jack\}, lists=\[a, b\], child=Child\{name='露西', age=11\}\}
