我想將服務器屬性從 application.yml 加載到 Configuration class 。我看到很多人已經問過同樣的問題，但沒有一個對我有用:(請幫我弄清楚我錯過了什么@Configuration @ConfigurationProperties("demo") public class Democonfig { private List<Archive> archive = new ArrayList<>(); public Democonfig(List<Archive> archive) { this.archive = archive; } // Getter and setter public static class Archive { private String host; private String database; private String port; public Archive(String host, String database, String port) { this.host = host; this.database = database; this.port = port; } // Getters and setters }}application.ymldemo: archive: - host: "localhost" database: "archive1" port: "27017" - host: "localhost" database: "archive2" port: "27017" 它的顯示異常Binding to target [Bindable@129425f type = java.util.List<com.example.demo.config.Democonfig$Archive>, value = 'provided', annotations = array<Annotation>[[empty]]] failed: Property: demo.archive[0].database Value: archive1 Origin: class path resource [application.yml]:5:15 Reason: The elements [demo.archive[0].database,demo.archive[0].host,demo.archive[0].port,demo.archive[1].database,demo.archive[1].host,demo.archive[1].port] were left unbound. Property: demo.archive[0].host Value: localhost Origin: class path resource [application.yml]:4:11 Reason: The elements [demo.archive[0].database,demo.archive[0].host,demo.archive[0].port,demo.archive[1].database,demo.archive[1].host,demo.archive[1].port] were left unbound. Property: demo.archive[0].port Value: 27017

您在嵌套靜態類中缺少 No arg 構造函數，實際上不需要為構造函數提供參數。只有 setter 和 getter很好
public static class Archive {
private String host;
private String database;
private String port;
public Archive() {
// TODO Auto-generated constructor stub
}
public Archive(String host, String database, String port) {
System.out.println("constri=uu Archive");
this.host = host;
this.database = database;
this.port = port;
}
public String getHost() {
return host;
}
public void setHost(String host) {
this.host = host;
}
public String getDatabase() {
return database;
}
public void setDatabase(String database) {
this.database = database;
}
public String getPort() {
return port;
}
public void setPort(String port) {
this.port = port;
}
@Override
public String toString() {
return "Archive [host=" + host + ", database=" + database + ", port=" + port + "]";
}
}
