在外部为类创建 jaxb 注释 [英] externally create jaxb annotations for class
问题描述
所以,通常我在代码中应用JAXB注解如下:
So, usually I apply JAXB annotations in the code as follows:
package com.example;
@XmlRootElement(name = "Foo", namespace = "example.com")
@XmlType(name = "Foo", namespace = "example.com")
public class Foo {
...
}
Foo 是一个 Java 类,用于与 Web 服务(通过 Spring/CXF)进行通信.以上注解,有助于在 wsdl 中适当地生成 XML Schema.
Foo is a java class that is used to communicate with web services (via Spring/CXF). The above annotations, help generate the XML Schema in the wsdl appropriately.
我遇到了无法修改类本身的情况,但我可以为生成架构的代码提供一个 jaxb 外部绑定文件.请注意,类中存在@XmlRootElement.
I have hit a situation where I can not modify the class itself, but I can provide an jaxb external binding file to the code that generates the schema. Note that the @XmlRootElement exists in the class.
如何编写一个等效的绑定文件来完成上述注释的作用?
How do I write an equivalent binding file that does what the above annotations do?
推荐答案
如果你只需要添加 @XmlType(name = "Foo", namespace = "example.com")
注解到生成的类,您可以使用 JAXB Annotate Plugin.此处是有关如何在外部绑定文件中定义注释的文档.
If you just need to add @XmlType(name = "Foo", namespace = "example.com")
annotation to the generated class you can use JAXB Annotate Plugin.
Here is documentation about how to define annotations in external binding files.
如果你使用 CXF 和 maven,你也可以像这样使用 cxf-codegen-plugin
If you're using CXF and maven you can also you cxf-codegen-plugin somehow like this
<plugin>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-codegen-plugin</artifactId>
<version>${cxf.version}</version>
<executions>
<execution>
<id>generate-sources</id>
<phase>generate-sources</phase>
<goals>
<goal>wsdl2java</goal>
</goals>
<configuration>
<sourceRoot>${service.src.dir}</sourceRoot>
<wsdlOptions>
<wsdlOption>
<wsdl>service.wsdl</wsdl>
<extraargs>
<extraarg>-xjc-Xannotate</extraarg>
<extraarg>-b</extraarg>
<extraarg>${wsdl.dir}/bindings.xjb</extraarg>
</extraargs>
</wsdlOption>
</wsdlOptions>
</configuration>
</execution>
</executions>
<dependencies>
<dependency>
<groupId>org.jvnet.jaxb2_commons</groupId>
<artifactId>jaxb2-basics-annotate</artifactId>
<version>${jaxb.commons.version}</version>
</dependency>
</dependencies>
</plugin>
你也可以使用 maven-jaxb2-plugin:
You can also use maven-jaxb2-plugin:
<plugin>
<groupId>org.jvnet.jaxb2.maven2</groupId>
<artifactId>maven-jaxb2-plugin</artifactId>
<version>${maven-jaxb2.version}</version>
<executions>
<execution>
<id>process-xsd</id>
<goals>
<goal>generate</goal>
</goals>
<phase>generate-sources</phase>
<configuration>
<schemaIncludes>
<include>**/*.xsd</include>
</schemaIncludes>
<bindingIncludes>
<include>**/*.xjb</include>
</bindingIncludes>
<generateDirectory>${jaxb.src.dir}</generateDirectory>
<extension>true</extension>
<args>
<arg>-Xannotate</arg>
</args>
<plugins>
<plugin>
<groupId>org.jvnet.jaxb2_commons</groupId>
<artifactId>jaxb2-basics-annotate</artifactId>
<version>${jaxb.commons.version}</version>
</plugin>
</plugins>
</configuration>
</execution>
</executions>
</plugin>
这是示例绑定文件:
<jaxb:bindings
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"
version="2.0">
<jaxb:bindings schemaLocation="schema.xsd" node="/xs:schema">
<jaxb:bindings node="//xs:complexType[@name='Foo']">
<annox:annotate target="class">
<annox:annotate annox:class="javax.xml.bind.annotation.XmlType" name="Foo" namespace = "example.com"/>
</annox:annotate>
</jaxb:bindings>
</jaxb:bindings>
</jaxb:bindings>
如果你还需要修改@XmlRootElement
,只需再添加一个annox:annotate
元素:
If you need to modify @XmlRootElement
too, just add another one annox:annotate
element:
<annox:annotate annox:class="javax.xml.bind.annotation.XmlRootElement" name="Foo" namespace = "example.com"/>
