在Wildfly中使用Jackson注释 [英] using Jackson annotations in Wildfly

问题描述

我正努力让Jackson Annotations在我的项目中工作，该项目部署在wildfly中。

我已经尝试过实现MessageBodyWriter 但没有成功。我的项目看起来像这样：我有一个带有ejb模块的耳朵，它带有带注释的Pojos，我有一个带有REST服务的Web模块。这是我当前的配置/依赖项：

ejb-module pom.xml：

 <依赖性> 
< groupId> com.fasterxml.jackson.core< / groupId> 
< artifactId> jackson-annotations< / artifactId> 
< version> 2.2.3< / version> 
< scope>提供< / scope> 
< type> jar< / type> 
< / dependency> 
  

rest-module pom.xml：

 没有杰克逊依赖。 
  

ear-project pom.xml：

 <依赖性> 
< groupId> com.fasterxml.jackson.core< / groupId> 
< artifactId> jackson-annotations< / artifactId> 
< version> 2.2.3< / version> 
< / dependency> 
< dependency> 
< groupId> com.fasterxml.jackson.core< / groupId> 
< artifactId> jackson-core< / artifactId> 
< version> 2.2.3< / version> 
< / dependency> 
< dependency> 
< groupId> com.fasterxml.jackson.core< / groupId> 
< artifactId> jackson-databind< / artifactId> 
< version> 2.2.3< / version> 
< / dependency> 
< dependency> 
< groupId> org.jboss.resteasy< / groupId> 
< artifactId> resteasy-jackson2-provider< / artifactId> 
< version> 3.0.6.Final< / version> 
< / dependency> 
  

ear-project /META-INF/jboss-deployment-structure.xml:

 < jboss-deployment-structure> 
< deployment> 
< exclusions> 
< module name =org.jboss.resteasy.resteasy-jackson-provider/> 
< / exclusions> 
< dependencies> 
< module name =org.jboss.resteasy.resteasy-jackson2-providerservices =import/> 
< / dependencies> 
< / deployment> 
< / jboss-deployment-structure> 
  

但忽略了jackson注释。我错过了什么？或者我做了太多？

解决方案

RESTEasy和Jackson依赖项应标记​​为< scope> ;提供与LT; /范围> 。

此外，如果您只在WAR中使用JAX-RS和Jackson，只需移动 jboss-deployment-structure.xml 到你的 WAR / WEB-INF 目录。如果您不想移动它，则可能需要添加<子部署/> 。

< pre class =lang-xml prettyprint-override> < jboss-deployment-structure>
< sub-deployment name =rest-module.war>
< exclusions>
< module name =org.jboss.resteasy.resteasy-jackson-provider/>
< / exclusions>
< dependencies>
< module name =org.jboss.resteasy.resteasy-jackson2-providerservices =import/>
< / dependencies>
< / sub-deployment>
< / jboss-deployment-structure>


I'm struggling to get Jackson Annotations to work in my project which is deployed in wildfly.

I already tried implementing a MessageBodyWriter but no success. My project looks like this: I have an ear with an ejb module which holds the annotated Pojos and I have a web module with the REST services. This is my current configuration / dependencies:

ejb-module pom.xml:

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-annotations</artifactId>
    <version>2.2.3</version>
    <scope>provided</scope>
    <type>jar</type>
</dependency>

rest-module pom.xml:

no jackson dependencies.

ear-project pom.xml:

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-annotations</artifactId>
    <version>2.2.3</version>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-core</artifactId>
    <version>2.2.3</version>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.2.3</version>
</dependency>
<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-jackson2-provider</artifactId>
    <version>3.0.6.Final</version>
</dependency>

ear-project /META-INF/jboss-deployment-structure.xml:

<jboss-deployment-structure>
    <deployment>
        <exclusions>
           <module name="org.jboss.resteasy.resteasy-jackson-provider"/>
        </exclusions>
        <dependencies>
            <module name="org.jboss.resteasy.resteasy-jackson2-provider" services="import"/>
        </dependencies>
    </deployment>
</jboss-deployment-structure> 

but the jackson annotations are ignored. What am I missing? or did I do too much?

解决方案

The RESTEasy and Jackson dependencies should be marked as <scope>provided</scope>.

Also if you're only using JAX-RS and Jackson in your WAR, just move jboss-deployment-structure.xml to your WAR/WEB-INF directory. If you don't want to move it you might need to add a <sub-deployment/>.

<jboss-deployment-structure>
    <sub-deployment name="rest-module.war">
        <exclusions>
           <module name="org.jboss.resteasy.resteasy-jackson-provider"/>
        </exclusions>
        <dependencies>
            <module name="org.jboss.resteasy.resteasy-jackson2-provider" services="import"/>
        </dependencies>
    </sub-deployment>
</jboss-deployment-structure>
