Here are different ways to read Spring boot different ways to read properties file using @ConfigurationProperties like convert properties to List,Map, read nested properties ect. Here is complete example of read spring boot read property value using @ConfigurationProperties.

1. Read property values to Map using @ConfigurationProperties
application.properties
app.domain=javadeveloperzone.com app.subdomain=api app.domainCount=10
AppProperties
package com.javadeveloperzone.model;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
import java.util.HashMap;
import java.util.Map;
/**
* Created by Java Developer Zone on 26-08-2017.
*/
@ConfigurationProperties()
@Component
public class AppProperties {
private java.util.Map<String, String> app = new HashMap<>(); // it will store all properties start with app
public Map<String, String> getApp() {
return app;
}
public void setApp(Map<String, String> app) {
this.app = app;
}
}
2. Read property values to List using @ConfigurationProperties
application.properties
app.information[0]=Java app.information[1]=Developer app.information[2]=Zone
AppProperties
package com.javadeveloperzone.model;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
import java.util.ArrayList;
import java.util.List;
/**
* Created by Java Developer Zone on 26-08-2017.
*/
@ConfigurationProperties(prefix = "app") // It will read all properties prefix with app
@Component
public class AppProperties {
private java.util.List<String> information=new ArrayList<>(); // it will contains all value of app.information[0],app.information[1],app.information[2]
public List<String> getInformation() {
return information;
}
public void setInformation(List<String> information) {
this.information = information;
}
}
3. Read Nested Property to Sub Class using @ConfigurationProperties
application.properties
app.information[0]=Java app.information[1]=Developer app.information[2]=Zone app.data.value=application value app.data.basicValue=application basic value
AppProperties
package com.javadeveloperzone.model;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
import java.util.ArrayList;
import java.util.List;
/**
* Created by Java Developer Zone on 26-08-2017.
*/
@ConfigurationProperties(prefix = "app") // It will read all properties prefix with app
@Component
public class AppProperties {
private java.util.List<String> information=new ArrayList<>();
private Data data;
public Data getData() {
return data;
}
public void setData(Data data) {
this.data = data;
}
public static class Data{
private String value;
private String basicValue;
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
public String getBasicValue() {
return basicValue;
}
public void setBasicValue(String basicValue) {
this.basicValue = basicValue;
}
}
public List<String> getInformation() {
return information;
}
public void setInformation(List<String> information) {
this.information = information;
}
}
