Spring 引导强制 PropertySource 从内部读取 jar

Question

I have my class that reads properties from application.properties in Spring Boot

@Configuration
@Component
@PropertySource("classpath:application.properties")
public class TestUtil {


    @Value("${usehttps}")
    private String usehttps="";

    @Value("${verifycertificate}")
    private String verifycertificate="";

}

The problem is that I want my code to read the application.properties from my internal jar file only. application.properties is in src/main/resources. If I create an application.properties with same properties on the location where my jar resides, the properties get overwritten by the external file at runtime. It can be a security issue in my case.

Can this be achieved?

Answer 1

The order in which your jar file and properties file are found in CLASSPATH matters here, as well as classloaders hierarchy (which JarLauncher gives you).

You can try to redefine bean for ResourcePatternResolver in order to change this behavior and manually scan all classloaders for the resource. But I would try a simple rearranging of CLASSPATH entries first.
