一、导入POM文件

  1. <!--导入配置文件处理器，配置文件进行绑定就会有提示-->
  2. <dependency>
  3.         <groupId>org.springframework.boot</groupId>
  4.         <artifactId>spring-boot-configuration-processor</artifactId>
  5.         <optional>true</optional>
  6. </dependency>
  8. <!--测试所需的依赖-->
  9. <dependency>
  10.   <groupId>org.springframework.boot</groupId>
  11.   <artifactId>spring-boot-test</artifactId>
  12.   <scope>test</scope>
  13. </dependency>
  14. <dependency>
  15.   <groupId>junit</groupId>
  16.   <artifactId>junit</artifactId>
  17.   <scope>test</scope>
  18. </dependency>
  19. <dependency>
  20.   <groupId>org.springframework</groupId>
  21.   <artifactId>spring-test</artifactId>
  22.   <scope>test</scope>
  23. </dependency>

二、Java Bean

  1. /**
  2.  * 将配置文件中配置的每一个属性的值，映射到这个组件对应的属性中
  3.  * @ConfigurationProperties：告诉SpringBoot将本类中的所有属性和配置文件中相关的配置进行绑定
  4.  *      prefix：说明配置文件中哪个下面的所有属性进行一一映射
  5.  *
  6.  * 说明：只有Spring容器中的组件才能使用Spring提供的@ConfigurationProperties功能
  7.  */
  8. @Component
  9. @ConfigurationProperties(prefix = "staff")
  10. public class Person {
  11.     private String name;
  12.     private Integer age;
  13.     private Boolean boss;
  14.     private Date birth;
  16.     private Map<String,Object> maps;
  17.     private List<Object> lists;
  18.     private Dog dog;
  20.     // get/set/toString方法省略
  21. }
  23. @Component
  24. public class Dog {
  25.     private String name;
  26.     private String age;
  28.     // get/set/toString方法省略
  29. }

三、配置文件编写

  1. staff:
  2.   name: 张三
  3.   age: 18
  4.   boss: false
  5.   birth: 2017/12/12
  6.   maps: {province: 江西, city: 赣州}
  7.   lists:
  8.     - 小明
  9.     - 小红
  10.   dog:
  11.     name: 旺财
  12.     age: 2

四、Test 测试Main方法

@RunWith(SpringRunner.class)
@SpringBootTest
public class SpringBootApplicationTest {
    @Autowired
    private Person staff;

    @Test
    public void TestPerson(){
        System.out.println(staff);
    }
}
