Cannot enhance @Configuration bean definition 'beanNamePlaceholderRegistryPostProcessor'

[chenrui333]

I have tried to apply the similar setup for the other app, but I have encountered this issue.

Jun 27, 2016 12:33:50 PM org.apache.catalina.startup.VersionLoggerListener log WARNING: Cannot enhance @Configuration bean definition 'beanNamePlaceholderRegistryPostProcessor' since its singleton instance has been created too early. The typical cause is a non-static @Bean method with a BeanDefinitionRegistryPostProcessor return type: Consider declaring such methods as 'static'.
Jun 27, 2016 12:34:25 PM org.apache.catalina.startup.TldConfig execute SEVERE: Context [] startup failed due to previous errors
Jun 27, 2016 12:34:32 PM org.springframework.web.context.support.XmlWebApplicationContext doClose

Can anyone takes a look at this?

[chenrui333]

As far as I can see in the code, it has been already declared as static return, why does it still complain?

FYI:
I have fixed this error

WARNING: @Bean method ServiceConfig.propertyPlaceholderConfigurer is non-static and returns an object assignable to Spring's BeanFactoryPostProcessor interface. This will result in a failure to process annotations such as @Autowired, @Resource and @PostConstruct within the method's declaring @Configuration class. Add the 'static' modifier to this method to avoid these container lifecycle issues; see @Bean javadoc for complete details.

By adding the static modifier to PropertySourcesPlaceholderConfigurer to

    @Bean
    public static PropertySourcesPlaceholderConfigurer propertyPlaceholderConfigurer() {
        return new PropertySourcesPlaceholderConfigurer();
    }

which I did not do before.

do you need further help?

[chenrui333]

For the tomcat one, yes.

[chenrui333]

I still have the tomcat issue, but the FYI message is just for another issue.

[chenrui333]

no way to reopen this?

[ulisesbocchio]

Yeah, please reopen and explain what's the situation. If you have sample code where the issue manifests even better so I can test and make sure I got you covered.

[chenrui333]

I found there is no way to re-open the issue.

The jar actually works pretty well with my sample codebase, but the real integration does the opposite.

[ulisesbocchio]

As far as warnings go,beanNamePlaceholderRegistryPostProcessor has been static for a while and there's no warning being raised. Check out the demo apps, there's a bunch of them

[ulisesbocchio]

what's the "real" integration? Can you create a repo with a "real" example in your github accound and share it with me?

[chenrui333]

Yes, I was trying to confirm with you whether you have seen that issue first.

Now, I guess I need to try to reproduce the issue now. I still do not know the root cause yet.

[chenrui333]

Will get back to this by the end of this week.

Seeing this issue with "com.github.ulisesbocchio:jasypt-spring-boot-starter:1.8"

[ulisesbocchio]

@gorky, Can you explain what you see? Is it just the warning? On tomcat? Do you have a code sample?

[gorky]

Thanks for your quick reply!

It's the Tomcat that is embedded in Spring Boot, although it hasn't started when these methods are logged. I don't currently have a code sample I can post in a public forum (my apologies).

Initializing String Encryptor based on properties with name 'jasyptStringEncryptor'
Annoyingly, I have a Jar in the classpath with a Config that is defining a bean with the name jasyptStringEncryptor and that config is definitely not getting loaded by Spring Boot. And this is causing decryption to fail as the seeding password doesn't get read/loading. When I drop the dependency on the jasypt-spring-boot-starter, the jar and included config are read but then fail on loading due to missing required jasypt classes.

We are using org.springframework.boot.loader.PropertiesLauncher with -Dloader.path set to include the jars that have our jasypt beans defined. Feel free to PM me.

Regards,
Steve

Found the issue with the jar not being picked up -- a directory name had be changed w/o an update in the -Dloader.path. When I corrected the directory name I started getting quite a few interesting failures -- trying to work my way through them. I will keep this thread updated.

[ulisesbocchio]

Alright, thanks, let me know if you need further assistance. I was checking the sample apps I have and I don't see the warning in any of them

[gorky]

Ok, this is issue is resolved. I've walked into some others, but I can open a ticket and supply a test case. Feel free to close this one as "End User Configuration Error -- corrected".

And thanks!
