spring spring-boot graalvm serverless native

spring-native's Introduction

spring-native is no longer actively maintained by VMware, Inc.

In order to adapt to the permissions changes on https://repo.spring.io/release/, Spring Native artifacts are now available from https://repo.spring.io/milestone/, Gradle and Maven build configuration of projects depending on Spring Native should be updated accordingly.

Spring Native provides beta support for compiling Spring applications to native executables using GraalVM native-image compiler, in order to provide a native deployment option typically designed to be packaged in lightweight containers.

Quick start

The easiest way to start with Spring Native is probably to go to start.spring.io, add the Spring Native dependency, and read the reference documentation. Make sure to configure properly the Spring AOT Maven and Gradle plugins that are mandatory to get proper native support for your Spring application.

Play with the samples

Note	You need to install the GraalVM `native-image` compiler, check the documentation for more details.

Download the latest release of this repository.
Go into the samples folder and pick one (e.g. cd samples/commandlinerunner)
Run ./build.sh which will run the regular JVM build, then a native image compilation, then test the result.

For more details on the samples see the samples documentation.

spring-native's Issues

Remove Hibernate Validator from web samples

Removing Hibernate Validator allows to reduce RSS memory by 3.3M and image size by 10M!

Avoid inclusion of ImageBanner and AWT classes when not needed

Analyzing classes included in a commandlinerunner sample Spring Boot native image with -H:+PrintAnalysisCallTree reveals that a significant number of java.awt.* classes are compiled and included (both with feature or agent).

The call tree shows that these classes are included because GraalVM analysis detects that SpringApplicationBannerPrinter used in SpringApplication could potentially create an instance of ImageBanner which uses these java.awt.* classes.

Moving banner classes initialization to build time is possible, probably an optimization that makes sense, but it does not solve this issue since the condition to know if ImageBanner and its related java.awt.* classes is only know at runtime. With close world + properties frozen at build time assumptions, it should be possible to avoid compiling and shipping ImageBanner in the native image.

This looks like an interesting use case to discuss with @bclozel and @snicoll.

Error occurred while native image building

I'm facing error during building native image.

Here is Dockerfile which I used (Current latest version is 19.3.0)

FROM oracle/graalvm-ce:latest

All steps are just copied appropriately from compile.sh
And get the error below:

Monitor memory, image size and startup time

Switch to build time initialization by default

To limit the RSS memory consumption.

Proposal:

Use --initialize-at-build-time in all compile.sh scripts
Remove the buildTimeInitialization part from initialization.json
Add classes known to be required to be initialized at runtime like org.springframework.core.io.VfsUtils, org.apache.tomcat.jni.SSL or InetAddress and related subclasses (see #21)
Check all samples and fine tune the feature accordingly

application.yml not being read at runtime

I only see application.yml in two samples. I don't think it is being read - the webclient is starting netty on port 8080 (which it doesn't do if you run in a regular JVM).

No @CompilationHint found for import selector

Hi,

So today I updated my Spring Feature clone repo and tried native compiling my Spring boot project with the recent changes of the master branch. But it seems I'm missing something (it worked perfecty with the lastest master version before merging of branch extensible-configuration).

I'm getting an error at native compiling :

Strange behaviour since I'm not using any cache library or functionality in my project.
My project uses resource bundles, jackson, has some basic @component beans without any database configuration, caching system nor web server controller.
I set spring.main.web-application-type to none and only have spring-boot-starter and spring-boot-starter-json (excluding spring-boot-starter-web) as dependencies.

Any idea where I should start looking for to fix this ?

As far as I understand, it means that ReactiveOAuth2ClientImportSelector is missing a configuration in spring-feature project.

I've tried to configure myself, but no luck. Any tips?

Introduce a spring-data-mongodb sample

Hi,

Error: Image build request failed with exit status 1

I tried to add some reflection hint to reflect.json like this :

{
		"name": "org.springframework.data.mongodb.repository.support.MongoRepositoryFactory",
		"allDeclaredConstructors": true,
		"allDeclaredMethods": true,
		"methods": [
			{
				"name": "<init>",
				"parameterTypes": [
					"org.springframework.data.mongodb.core.MongoOperations"
				]
			}
		]
	}

I modified the class Type.java of the feature to add some logs and I am surprised to see that the parameters of the constructor is not detected.
This is the change I did :

Auto config warning in native build generation

I am finding lot of warning that reflect.json not found or so when running commanlinerunner sample with compile.sh

Is there a workaround for this or any plan's to avoid?

output.txt

Add actuator support

I'm seeing the error below when trying to use the command line runner example.

No @CompilationHint found for import selector: org.springframework.boot.actuate.autoconfigure.web.server.ManagementContextConfigurationImportSelector

What is the best way to determine the root cause of an error during native-image?

Provide metrics as CSV

As a follow-up of #30, we should generate a CSV file or display the data in a CSV friendly format to allow easy comparison of metrics collected such as RSS, image size or startup time.

Support gRPC 1.25.0

On this riff subproject, we realized that native image generation did not work with gRPC 1.25.0.
It does work with 1.24.1 though.

Here is a log of the compilation error: https://github.com/projectriff/streaming-processor/runs/324831191#step:5:378

<scope>runtime</scope>
</dependency>

application.properties

spring.datasource.url=jdbc:mysql://localhost:3306/bar
spring.datasource.username=root
spring.datasource.password=password

ConditionalOnUse

Here is the idea. ConditionalOnUse is not an annotation but a behavior that intends to avoid creating unused feature even if they are on the classpath if the related beans and/or annotations are not used.

The interesting point of convergence here is that with the tracing agent we need a phase where we run the application. Combined with closed world assumptions and the fact that most singletons are instantiated at startup, could we use this opportunity to identify unused beans, to remove them from what we provide to native-image allowing then to avoid compiling and bundled these classes in the native image? This could for example apply to RestTemplate and WebClient builders and avoid to load client related infrastructure when just the server is needed.

Another source of waste is Hibernate Validator (provided by default with spring-boot-starter-web and spring-boot-starter-webflux via spring-boot-starter-validation), I have briefly discuss this one with @bclozel, it is more complex because it depends of the validation classes used in the application, so just analyzing the whole classpath is likely to not be precise enough. A more simple and pragmatic approach for this case would be to find a way to solve how users could use thespring-boot-starter-validation without the non-intuitive exclude, that could potentially allow to avoid providing this spring-boot-starter-validation by default with the web starters.

Any thoughts?

Logback's File Appender in build time causes failed native image creation

Hi. I'm working on a project involving Spring Boot with WebSockets, and using Logback Classic as the logging implementation API.
The project is packaged on a war file with an embedded Tomcat.

Here are the logging dependencies in pom.xml:

		<!-- Logging APIs -->
		<dependency>
			<groupId>org.slf4j</groupId>
			<artifactId>log4j-over-slf4j</artifactId>
		</dependency>
		<dependency>
			<groupId>org.slf4j</groupId>
			<artifactId>jcl-over-slf4j</artifactId>
		</dependency>
		<dependency>
			<groupId>org.slf4j</groupId>
			<artifactId>jul-to-slf4j</artifactId>
		</dependency>
		<dependency>
			<groupId>ch.qos.logback</groupId>
			<artifactId>logback-classic</artifactId>
		</dependency>

and this is the logback.xml located at src/main/resources

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xml>
<configuration debug="false" scan="false">
	<statusListener class="ch.qos.logback.core.status.NopStatusListener" />
	<appender name="FILE"
		class="ch.qos.logback.core.rolling.RollingFileAppender">
		<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
			<!-- Daily rollover -->
			<fileNamePattern>logs/signaling-%d{yyyyMMdd}.log</fileNamePattern>
			<!-- Keep 7 days' worth of history -->
			<maxHistory>7</maxHistory>
			<!-- logs up to a maximum size of 1GB -->
			<totalSizeCap>1GB</totalSizeCap>
		</rollingPolicy>
		<encoder>
			<pattern>%date{ISO8601} %-5level [%t] %X{uid} %c{0}: %msg%n</pattern>
		</encoder>
	</appender>
	<root level="INFO">
		<appender-ref ref="FILE" />
	</root>
</configuration>

As you can see above, the logging configuration file defines a File Appender (specifically the RollingFileAppender) which will create a file when the logging backend is instanciated at boot time.

The problem is that I'm not able to create a native image with file creation during native image build time.

After collecting every class involved in build time for the reflective instantiation of logback's file appender and put them into respective Spring Graal Feature files:
initialization.json, proxies.json, reflect.json, resources.json
(see attached file native-image-missing-features.txt)
I get the next message:

[signaling.war:3400]     analysis: 853,104.17 ms
Error: Detected a FileDescriptor in the image heap. File descriptors opened during image generation are no longer open at image run time, and the files might not even be present anymore at image run time. Object has been initialized without the native-image initialization instrumentation and the stack trace can't be tracked. The object was probably created by a class initializer and is reachable from a static field. You can request class initialization at image run time by using the option --initialize-at-build-time=<class-name>. Or you can write your own initialization methods and call them explicitly from your main entry point.
Detailed message:
Trace:  object java.io.FileOutputStream
        object ch.qos.logback.core.recovery.ResilientFileOutputStream
        object ch.qos.logback.core.rolling.RollingFileAppender
        object ch.qos.logback.core.status.InfoStatus
        object java.lang.Object[]
        object java.util.ArrayList
        object ch.qos.logback.core.BasicStatusManager
        object ch.qos.logback.classic.LoggerContext
        object org.slf4j.impl.StaticLoggerBinder
        field org.slf4j.impl.StaticLoggerBinder.SINGLETON

Which is due to the attempt of a file creation given the File Appender configured in logback.properties.
See file attached file native-image-missing-features.txt to get an idea of all the missing features I had to add.

Is this caused by a misconfiguration on my project? Or is it a missing feature to allow logback's file appender correctly create a file descriptor in build time?

Aside note: if I use an empty logback.xml (I mean no appenders) then the error message disappears.

Upgrade to GraalVM 19.3

Main breaking change is about InetAddress and related subclasses, after the java 11 support refactoring, they now need to be initialized at runtime and not at build time. See this related issue.

What do I need to do in order to compile successfully?

Supports applications configured with Jafu

Supports Spring Boot applications configured with functional bean defintion like what is done in Spring Fu incubator in order to allow comparison between annotation and functional bean registration. We can potentially reuse code from Jafu (the Java DSL).

Setup CI

Reduce static configuration

Currently work-in-progress in wip_optimizing branch.

Automated test of samples

Automated test of samples via curl and assertions on standard output.

Make all substitutions active only when related classes are present

Raised by @ericbottard for Riff but could be useful to make substitution more flexible, for example for Spring Framework applications that do not use Spring Boot.

proxy and reflection settings are insufficient for Pet Clinic

The Pet Clinic application can be built as Native Image.
However, when I click the "Add New Pet" button in "Owner Information" page, an internal error has occurred.

The settings seem to be insufficient.
After I added org.springframework.web.bind.annotation.ModelAttribute and org.springframework.format.annotation.DateTimeFormat to both proxies.json and reflect.json, it works fine.

Optimize image size (step 1)

For now without modification on Framework / Boot. More optimizations will come later.

GraalVM Community Edition 20.0.0 (Java 8)
spring-graal-native from master branch

Is there anything I missed?

Remove CGLIB classes from native images

Native images are currently compiled and shipped with CGLIB classes provided with Spring Framework in org.springframework.cglib package, they should be excluded via configuration (in the feature ?) and we should check that nothing breaks on Spring Framework side. Otherwise we should create a dedicated issue in Spring Framework to make it possible to run it without CGLIB.

Notice that vanilla-orm2 works, and the main difference between the 2 seems to be the fact that vanilla-orm uses @Transactional while vanilla-orm2 uses programmatic transactions. Surprisingly, spring-petclinic-jpa works even if it uses @Transactional.

Refactor modules

Create a dedicated spring-graal-native-substitutions module
Create a shaded spring-graal-native module for user consumption

Upgrade to Spring Boot 2.2.3

Configure mandatory native-image parameters by default

Spring support can't work without --allow-incomplete-classpath --report-unsupported-elements-at-runtime , we should configure these by default (and document it).

Support running JUnit 5 tests as native image

@aclement has recently demonstrated it is possible to run a subset of Spring Framework unit tests as native images. The purpose of this issue is to start from that POC to experiment and identify the next steps toward a more robust and mature arrangement that would allow to run a subset of Spring Framework and Spring Boot JUnit 5 tests as a native image in order to:

Identify in an automated fashion what part of Spring ecosystem works as native image and what part does not
Provide regression testing for each update of Spring Framework, Spring Boot and GraalVM native.
Provide a way for end user Spring Boot applications to be tested
Provide a way to test GraalVM native support for libraries that support it natively like Netty or Tomcat

Goal of this issue:

Provide a way to run these tests via command line/Gradle/Maven
Provide a way to identify tests that will be ran as native images and those who will not because for example by design they can't due to native images limitations (configuration whitelisting or backlisting, support for conditional execution via annotations and ExecutionCondition).
Is JUnit console launcher this right way to support it or not?
What kind of output are we expecting? Could we generate similar output than JUnit 5 Maven/Gradle regular OpenJDK plugins?
Create GraalVM native support for JUnit 5 via a feature or JSON configuration files (the related module can live in spring-graal-native for now)
Allow to run tests locally (using java and native-image currently in the path, or in a container)
Explore with @bsideup the opportunity of leveraging Testcontainers for testing in containers
Check if that's interesting to use GraalVM capability to create shared libraries + calling them from Java code
Provide a dedicated wiki page.

Non-goal of this issue:

Integration in IDEs
JUnit 4 support

Impossible to change log level in application.yml

In commandlineruner, changing log level in application.yml from INFO to DEBUG does nothing. Interestingly, it works when using application.properties.
