springBoot属性配置和使用

Spring Boot 属性配置和使用

1、添加属性文件 application.properties (名字固定)

 

2、访问端口生效

 

3、更多配置参考

4、自定义属性读取

修改配置文件，添加自定义属性配置

 

我要在类中读取这个配置信息，修改HelloController  

方式一：

@Autowired

private Environment env;

@RequestMapping("/env")

public String env () {

String property = env.getProperty("url");

System.out.println(property);

return property;

}

方式二：

@Value("${url}")

private String url;

@RequestMapping("/env")

public String env() {

return url;

}

访问和后台

 

5、复杂属性读取

添加复杂属性

 

定义复杂属性对应的pojo,添加特定注解

@Component

@ConfigurationProperties(prefix="person")

在Controller中使用

@Autowired

private Person person;

@RequestMapping("/javaproperty")

public Person javaproperty(){

    System.out.println(person);

    return person;

}

访问结果

 

6、更换配置类型application.yml (官方推荐配置文件类型)

配置文件格式和内容如下

#指定tomcat的端口

server: 

  port: 8088

 

#任意指定属性

url: http://spring.io

 

#复杂配置参数

person:

 name: springbooooot

 age: 2

注意：重启项目之前将原来的application.properties删除

访问效果一致
