在应用程序上工作时,我也希望将JAXB类用于JSON绑定。
因此,对于某些课程,我需要使用@JsonTypeInfo
进行注释。
所以我想我会使用自定义绑定。
以下是我的XJB文件的样子:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xml>
<jaxb:bindings version="1.0"
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
xmlns:annox="http://annox.dev.java.net"
jaxb:extensionBindingPrefixes="xjc">
<jaxb:bindings schemaLocation="../schema/im/vehicle.xsd">
<jaxb:bindings node="xs:complexType[@name='Vehicle']">
<annox:annotate target="class">
<annox:annotate annox:class="com.fasterxml.jackson.annotation.JsonTypeInfo(use = com.fasterxml.jackson.annotation.JsonTypeInfo.Id.NAME, include = com.fasterxml.jackson.annotation.JsonTypeInfo.As.PROPERTY, property = 'subVehicleType')"/>
</annox:annotate>
</jaxb:bindings>
</jaxb:bindings>
</jaxb:bindings>
这就是我想要的课程:
@JsonTypeInfo(use=Id.CLASS, include=As.PROPERTY, property="subVehicleType")
但我一直收到以下错误:
org.jvnet.annox.parser.exception.AnnotationElementParseException: Could not parse the annotation element.

我做错了吗?
更新
我在答案中提到过:它在我的TEST独立项目中有效,但是当我在我的主项目中执行相同操作时,我得到以下API Incompatibility error
[ERROR] Failed to execute goal org.jvnet.jaxb2.maven2:maven-jaxb2-plugin:0.13.2:generate (default) on project Domain: Execution default of goal org.jvnet.jaxb2.maven2:maven-jaxb2-plugin:0.13.2:generate failed: An API incompatibility was encountered while executing org.jvnet.jaxb2.maven2:maven-jaxb2-plugin:0.13.2:generate: java.lang.NoSuchMethodError: japa/parser/JavaParser.parse(Ljava/io/Reader;Z)Ljapa/parser/ast/CompilationUnit; (loaded from file:/C:/JavaDev/.m2/repository/com/google/code/javaparser/javaparser/1.0.8/javaparser-1.0.8.jar by java.net.URLClassLoader@ce3ebdfb) called from class org.jvnet.annox.japa.parser.AnnotationExprParser (loaded from file:/C:/JavaDev/.m2/repository/org/jvnet/annox/annox/1.0.2/annox-1.0.2.jar by java.net.URLClassLoader@ce3ebdfb).
我不确定哪个其他api导致了这种冲突。但是从上面的消息中很难理解。
答案 0 :(得分:1)
免责声明:我是jaxb2-annotate-plugin的作者。
正确的语法是:
<annox:annotate target="class">
@com.fasterxml.jackson.annotation.JsonTypeInfo(
use = com.fasterxml.jackson.annotation.JsonTypeInfo.Id.NAME,
include = com.fasterxml.jackson.annotation.JsonTypeInfo.As.PROPERTY,
property = "subVehicleType")
</annox:annotate>
基本上你将如何用Java编写它,但使用FQCN。
