debug中 org.apache.dubbo.config.ApplicationConfig#isValid()-----name是null

@zzqsy I could not reproduce this problem in a local test.

Thanks for the feedback. We'll look at the jdk11 issue.

[chickenlj]

Thanks for the feedback. We'll look at the jdk11 issue.

[Huangxuny1]

@chickenlj I investigate the issue in jdk11 , It's becase of @PostConstruct (javax.annotation.PostConstruct)

in I can't use @PostConstruct and @PostDestroy with Java 11

Note that both @PostConstruct and @PreDestroy annotations are part of Java EE. And since Java EE has been deprecated in Java 9 and removed in Java 11 we have to add an additional dependency to use these annotations:

however , application name inject by

@Parameter(key = APPLICATION_KEY, required = true, useKeyAsProperty = false)
    public String getName() {
        return name;
    }

and in AbstractConfig.java

    @PostConstruct
    public void addIntoConfigManager() {
        ApplicationModel.getConfigManager().addConfig(this);
    }

this method won't be invoked , so It's will throw

No application config found or it's not a valid config! Please add to your spring config.

ConfigValidationUtils .java

  if (!config.isValid()) {
            throw new IllegalStateException("No application config found or it's not a valid config! " +
                    "Please add <dubbo:application name=\"...\" /> to your spring config.");
        }

I try to add dependency to my project

<dependency>
         <groupId>javax.annotation</groupId>
         <artifactId>javax.annotation-api</artifactId>
         <version>1.3.2</version>
</dependency>

it works .

So... do you have some advice to resolve it ?

[Huangxuny1]

I have a workaround , above jdk9 , It introduces "JEP 238: Multi-Release JAR Files"

A multi-release JAR ("MRJAR") will contain additional directories for classes and resources specific to >particular Java platform releases. A JAR for a typical library might look like this:

jar root

• A.class
• B.class
• C.class
• D.class
  Suppose there are alternate versions of A and B that can take advantage of Java 9 features. We can bundle them into a single JAR as follows:

jar root

• A.class
• B.class
• C.class
• D.class
• META-INF
  
  
  
  • versions
    
    
    
    
    
    • 9
      
      
      
      
      
      
      
      • A.class
      
      
      
      
      • B.class

When I use jdk8,it worked.Thanks.
