@ConfigurationProperties使用

@ConfigurationProperties(

        prefix = "hello.properties"

)

public class MyProperties {


    private String myKey;

    private List<String> stringList;

    private Duration duration;


    public String getMyKey() {

        return myKey;

    }


    public
 
 void setMyKey(String myKey) {

        this.myKey = myKey;

    }


    public List<String> getStringList() {

        return stringList;

    }


    public void setStringList(List<String> stringList) {

        this.stringList = stringList;

    }


    public Duration getDuration() {

        
 
return duration;

    }


    public void setDuration(Duration duration) {

        this.duration = duration;

    }


    @Override

    public String toString() {

        return "MyProperties{" +

                "myKey='" + myKey + '\'' +

                ", stringList=" + stringList +

                ", duration=" + duration +

                '}';

    }

}
 

prefix屬性是配置檔案裡的字首，即配置檔案中以字首 + 變數名的形式配置一條記錄，來對應類中的一個變數，如下：

hello.properties.myKey=hello

hello.properties.duration=20s

hello.properties.string-list[0]=Acelin

hello.properties.string-list[1]=nice

@ConfigurationProperties特點

hello.properties.myKey=hello

hello.properties.mykey=hello

hello.properties.my-key=hello

hello.properties.my_key=hello

hello.properties.MY_KEY=hello

hello.properties.MY-KEY=hello
