How to access a value defined in the application.properties file in Spring Boot

You can use the @Value annotation and access the property in whichever Spring bean you're using

@Value("${userBucket.path}")private String userBucketPath;

The Externalized Configuration section of the Spring Boot docs, explains all the details that you might need.

Another way is injecting org.springframework.core.env.Environment to your bean.

@Autowiredprivate Environment env;....public void method() {    .....      String path = env.getProperty("userBucket.path");    .....}

@ConfigurationProperties can be used to map values from .properties( .yml also supported) to a POJO.

Consider the following Example file.

.properties

cust.data.employee.name=Sachincust.data.employee.dept=Cricket

Employee.java

import org.springframework.boot.context.properties.ConfigurationProperties;import org.springframework.context.annotation.Configuration;@ConfigurationProperties(prefix = "cust.data.employee")@Configuration("employeeProperties")public class Employee {    private String name;    private String dept;    //Getters and Setters go here}

Now the properties value can be accessed by autowiring employeeProperties as follows.

@Autowiredprivate Employee employeeProperties;public void method() {   String employeeName = employeeProperties.getName();   String employeeDept = employeeProperties.getDept();}
