springboot读取配置文件方式

方法一:

@Value注解的方式取值

设定appliction.properties的配置信息

xiaoming.sex=boy
xiaoming.age=18
xiaoming.score=98

使用@Value取值

@RestController
public class PersonController {
    @Value("${xiaoming.sex}") private String sex; @Value("${xiaoming.age}") private Integer age; @Value("${xiaoming.score}") private Integer score; @RequestMapping("/xiaoming") public String get() { return String.format("小明==》性别:%s-----年龄:%s-----分数:%s",sex,age,score); } }

页面展示

小明==》性别:boy-----年龄:18-----分数:98

方法二:

使用@ConfigurationProperties赋值给实体类

设定appliction.yml的配置信息

person:
  name: xiaoming
  age: 18

@ConfigurationProperties赋值给实体类

@Component
@ConfigurationProperties(prefix = "person")
public class Person { private String name; private Integer age; public String getName() { return name; } public void setName(String name) { this.name = name; } public Integer getAge() { return age; } public void setAge(Integer age) { this.age = age; } }

请求信息

@Autowired
    private Person person;

    @RequestMapping("/person")
    public String getPerson() { return String.format("姓名:%s-----年龄:%s",person.getName(),person.getAge()); }

页面展示

姓名:xiaoming-----年龄:18

方法三:

通过注入获取Environment对象,然后再获取定义在配置文件的属性值

设定appliction.properties的配置信息

springboot.test=hello-springboot

获取Environment对象,然后再获取定义在配置文件的属性值

 private static final String hello = "springboot.test";
    @Autowired private Environment environment; @RequestMapping("/enviro") public String getenv() { return String.format("测试Environment:" + environment.getProperty(hello)); }

页面展示

测试Environment:hello-springboot
