Spring boot YAML 配置:参数化键 [英] Spring boot YAML config : Parametred keys
本文介绍了Spring boot YAML 配置:参数化键的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
spring boot 是否允许使用 YAML 的参数化键?
Is spring boot allow to use parametred keys using YAML ?
参数化键示例:
myapp.configured.key: This is your email > {0} And this is your name > {1}
在我的 Java 课程中，我想做这样的事情:
And in my Java class i want to do some thing like this:
@Inject
private Environment env;//import org.springframework.core.env.Environment;
String email = "email@email.com"
String name = "User Name";
String key=env.getProperty("myapp.configured.key", email, name);
System.out.println(key);
输出将是这样的:
This is your email > email@email.com And this is your name > User Name
推荐答案
如果你的 email 和 name 也是配置键，你可以在你的消息中引用它们(但有点奇怪)
If your email and name are also configuration keys, you can refer to them in your message (but it's a bit weird)
myapp.configured.email: email@example.com
myapp.configured.name: John Smith
myapp.configured.key: This is your email > ${myapp.configured.email} And this is your name > ${myapp.configured.name}
Environment 没有这样的 API，作为一个 Spring Boot 用户，你甚至不应该接触这些东西(检查 @ConfigurationProperties 以获取配置的类型安全绑定).
The Environment has no such API and as a Spring Boot user you shouldn't even touch that stuff (check @ConfigurationProperties for type safe binding of configuration).
