Java Wildfly 10和Jackson 2

我有这样的问题

maven中的所有依赖项-提供

jboss部署结构 是这样吗

<deployment>
    <dependencies>
        <module name="by.lib" meta-inf="export" export="true"/>
        <module name="org.jboss.resteasy.resteasy-jackson2-provider" services="import"/>
        <!--<module name="com.fasterxml.jackson.jaxrs.jackson-jaxrs-json-provider"  export="true"/>-->
        <!--<module name="org.jboss.resteasy.resteasy-jaxrs"  export="true"/>-->
        <!--<module name="com.fasterxml.jackson.core.jackson-databind"  export="true"/>-->
        <!--<module name="com.fasterxml.jackson.core.jackson-core"  export="true"/>-->
        <!--<module name="com.fasterxml.jackson.core.jackson-annotations"  export="true"/>-->
        <!--<module name="org.jboss.resteasy.resteasy-jackson2-provider"  export="true"/>-->
    </dependencies>
    <exclude-subsystems>
        <subsystem name="logging"/>
        <subsystem name="resteasy"/>
    </exclude-subsystems>
</deployment>

或

当我尝试

@Provider
@Produces(MediaType.APPLICATION_JSON)
public class ConfiguredRESTProvider implements ContextResolver<ObjectMapper> {

    private static ObjectMapper mapper;

    static {
        mapper = new ObjectMapper();
        AnnotationIntrospector primary = new JacksonAnnotationIntrospector();
        AnnotationIntrospector secondary = new JaxbAnnotationIntrospector(mapper.getTypeFactory());
        AnnotationIntrospector pair = AnnotationIntrospectorPair.create(primary, secondary);
        mapper.setAnnotationIntrospector(pair);

        mapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, true);
        // TODO Разбраться почему не отрабатывае? ("balanceAmount": 2.41E8)
        mapper.configure(SerializationFeature.WRITE_BIGDECIMAL_AS_PLAIN, true);
        mapper.configure(JsonGenerator.Feature.WRITE_BIGDECIMAL_AS_PLAIN, true);
        mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
        // mapper.configure(JsonGenerator.Feature.WRITE_NUMBERS_AS_STRINGS,true);
        mapper.setSerializationInclusion(JsonInclude.Include.NON_EMPTY);
    }

    // public void ConfiguredRESTProvider() {
    // // ObjectMapper mapper = new ObjectMapper();
    // ObjectMapper mapper = locateMapper(type, json);
    // ObjectMapper mapper = super._mapperConfig.getDefaultMapper();
    // // AnnotationIntrospector primary = new JacksonAnnotationIntrospector();
    // // AnnotationIntrospector secondary = new JaxbAnnotationIntrospector(mapper.getTypeFactory());
    // // AnnotationIntrospector pair = AnnotationIntrospectorPair.create(primary, secondary);
    // // mapper.setAnnotationIntrospector(pair);
    //
    // mapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, true);
    // // TODO Разбраться почему не отрабатывае? ("balanceAmount": 2.41E8)
    // mapper.configure(SerializationFeature.WRITE_BIGDECIMAL_AS_PLAIN, true);
    // mapper.configure(JsonGenerator.Feature.WRITE_BIGDECIMAL_AS_PLAIN, true);
    // mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
    // // mapper.configure(JsonGenerator.Feature.WRITE_NUMBERS_AS_STRINGS,true);
    // mapper.setSerializationInclusion(JsonInclude.Include.NON_EMPTY);
    // super.setMapper(mapper);
    // }

    @Override
    public ObjectMapper getContext(Class<?> aClass) {
        return mapper;
    }

}

NoClassDefFoundError

for

JaxbAnnotationIntrospector

表示模块

jackson模块jaxb注释

未指定为依赖项

此模块包含类

JaxbAnnotationIntrospector

我认为应将依赖项添加为：

<module name="com.fasterxml.jackson.module.jackson-module-jaxb-annotations"/>

---

根据需要指定导出。

关于此错误消息：

java.lang.NoClassDefFoundError: Failed to link 
com/fasterxml/jackson/jaxrs/base/ProviderBase

或：

WildFly没有加载/导出所有需要的库。您的jboss部署结构.xml文件应该如下所示：

<deployment>
  <dependencies>
    <module name="org.jboss.resteasy.resteasy-jackson2-provider" services="import"/>
    <!-- This module contain the ProviderBase class: -->
    <module name="com.fasterxml.jackson.jaxrs.jackson-jaxrs-json-provider" export="true"/>
  </dependencies>
  <exclusions>
    <!-- Just to make sure these modules are not loaded -->
    <module name="org.jboss.resteasy.resteasy-jackson-provider"/>
    <module name="org.jboss.resteasy.resteasy-jettison-provider"/>
  </exclusions>
</deployment>

---

第二次尝试时，您既包括又排除了

org.jboss.resteasy.resteasy-jackson2-provider

模块。我不确定哪一个会赢。
