springboot如何从自定义yml加载属性

Question

I have a property bean (example):

@Data
public class MyProperty {
    private String name;
    private String address;
}

and I have a custom yml file in classpath named: my_property.yml

my.property:
  name: testName
  address: testAddress

How to load this file to my property bean? Not using @PropertyResource , because I want to use the yml file. Thanks.

Answer 1

There are two properties you can look at -

1. spring.config.name - If you don't like application as your file name for eg-

     java -Dspring.config.name = my_property myjar.jar 

2. spring.config.location - To tell where your files lie

More information is well-documented here

spring documentation

Answer 2

@PropertySource is the way to include external/custom properties but unfortunately is doesn't work with yaml files due to this issue .

You need to load these yaml files on your own by simply writing EnvironmentPostProcessor and adding it META-INF/spring.factories .

This is described in below Spring documentation (slight difference among versions).
Spring boot 1.5.x
Spring boot 2.x

Follow: http://www.baeldung.com/spring-yaml

The relative path of application.yml file is /myApplication/src/main/resources/application.yml .

and access is:

@Autowired
private YAMLConfig myConfig;

I put my application.properties file at src/main/resources/ End my @SpringBootApplication read.

application.properties file

spring.jpa.hibernate.ddl-auto=create
spring.datasource.url=***
spring.datasource.username=***
spring.datasource.password=***
