Java 9 - REST with Spring 5 & Jigsaw - Is it possible?

java-9

I've been looking into JDK 9's Jigsaw modular system.

It works quite nicely when compiling from the command line (at least the quickstart does).

But I'm trying to create a simple REST API using Spring and Jigsaw. Spring 5.0.0 M1 is said to have

Full compatibility with JDK 9 as of July 2016

I also want the REST API to work with Maven. According to this Maven page, Maven should be able to work with Java 9 (or am I reading this wrong?).

When having my JAVA_HOME point to my JDK, I cannot seem to run mvn spring-boot:run on my Spring Boot application - it throws a lot of exceptions, such as:

FoundError: javax/xml/bind/ValidationException
2016-09-14 10:43:42.704 ERROR 120408 --- [           main] o.s.boot.SpringApplication               : Application startup failed

Running mvn -version gives me:

Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-10T17:41:47+01:00)
Maven home: C:\Program Files\apache-maven-3.3.9\bin\..
Java version: 9-ea, vendor: Oracle Corporation
Java home: C:\Program Files\Java\jdk-9
Default locale: en_US, platform encoding: Cp1252
OS name: "windows 10", version: "10.0", arch: "amd64", family: "dos"

Is it currently possible to create this REST API with Spring and Java 9 using Jigsaw? Or should I stick to Java 8 until around March/July 2017?

What is @RestController in spring boot?

Spring RestController annotation is a convenience annotation that is itself annotated with @Controller and @ResponseBody . This annotation is applied to a class to mark it as a request handler. Spring RestController annotation is used to create RESTful web services using Spring MVC.

What is the difference between @controller and @RestController?

@Controller is used to mark classes as Spring MVC Controller. @RestController annotation is a special controller used in RESTful Web services, and it's the combination of @Controller and @ResponseBody annotation. It is a specialized version of @Component annotation.

What is @ResponseBody in spring boot?

The @ResponseBody annotation tells a controller that the object returned is automatically serialized into JSON and passed back into the HttpResponse object. When you use the @ResponseBody annotation on a method, Spring converts the return value and writes it to the HTTP response automatically.

What new features of Java 9 10 11 Have you used recently?

Reactive Streams: Overview of reactive programming; Understanding the Java Flow API; Implementing publishers and subscribers; Implementing processors; Practical applications. New Language Features: Private methods in interfaces; Type interference; Miscellaneous improvements; Multi-version JARs.

rorschach's answer is not correct because hibernate validation exception is in a different package, different class. I don't have enough rep points to comment directly.

zhy2002's answer is correct for the Java-9-only case but won't work for Java 8 or 10 (because this java ee module is deprecated and will be removed in 10). If you want it to work with Java 8 and Java 9 as we do, you can add this dependency:

Gradle:

compile "javax.xml.bind:jaxb-api:2.3.0"

Maven:

<!-- https://mvnrepository.com/artifact/javax.xml.bind/jaxb-api -->
<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.0</version>
</dependency>

peerless-phreap

Since you are using non-default modules you need to add it manually when you compile and run Java9:

javac --add-modules java.xml.bind ...
java  --add-modules java.xml.bind ...

If there are other missing java ee classes try adding the barrel module:

--add-module java.se.ee
