我有类似的问题 Jackson 2 on Wildfly 10: How to load ProviderBase?

所有maven的家属 - 提供

的JBoss部署结构 是不是？

<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>

在模块中，我对jackson-jaxrs-base-2.8.5

有所依赖

我发现了不同的错误

当我尝试

时 
@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;
    }

}

关于此错误消息：

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

或：

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

WildFly未加载/导出所有需要的库。您的 jboss-deployment-structure.xml 文件应如下所示：

<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>

答案 1 :(得分：0)

<meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate" /> <meta http-equiv="Pragma" content="no-cache" /> <meta http-equiv="Expires" content="0" /> 的

NoClassDefFoundError表示模块JaxbAnnotationIntrospector未指定为依赖项。

此模块包含课程jackson-module-jaxb-annotations。

我认为依赖项应该添加为：

JaxbAnnotationIntrospector

根据需要指定导出。
