我可以防止字节好友发出注释的默认值

Question

是否有任何方法可以防止字节好友为我添加的注释发出默认值？使用以下示例，基于构建插件，我想查看从baz字段上的@XmlAttribute注释中省略的冗余required和namespace值。

foo/bar.java：

package foo;
import javax.xml.bind.annotation.XmlAttribute;
public class Bar {
    @XmlAttribute(name = "qux")
    public String qux;
}

net/bytebuddy/test/simpleplugin.java：

...    
public class SimplePlugin implements Plugin {
...    
    @Override
    public DynamicType.Builder<?> apply(DynamicType.Builder<?> builder, TypeDescription typeDescription) {
        return builder.defineField("baz", String.class, Visibility.PUBLIC)
            .annotateField(AnnotationDescription.Builder.ofType(XmlAttribute.class)
                .define("name", "baz")
                .build());
    }
}

foo/bar.class：

package foo;
import javax.xml.bind.annotation.XmlAttribute;
public class Bar {
    @XmlAttribute(
        name = "qux"
    )
    public String qux;
    @XmlAttribute(
        name = "baz",
        required = false,
        namespace = "##default"
    )
    public String baz;
    public Bar() {
    }
}

字节好友可以配置为跳过默认注释值。但是，配置字节伙伴在实现Plugin接口的转换构建插件的范围之外。字节好友API提供了一个单独的EntryPoint接口，可以实现该接口以控制字节好友的初始化。

net/bytebuddy/test/simpleentrypoint.java：

package net.bytebuddy.test;
...
public class SimpleEntryPoint implements EntryPoint {
    @Override
    public ByteBuddy getByteBuddy() {
        return new ByteBuddy()
            .with(AnnotationValueFilter.Default.SKIP_DEFAULTS);
    }
    ...
}

pom.xml：

...
    <plugin>
            <groupId>net.bytebuddy</groupId>
            <artifactId>byte-buddy-maven-plugin</artifactId>
            <executions>
                <execution>
                    <goals>
                        <goal>transform</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <initialization>
                    <entryPoint>net.bytebuddy.test.SimpleEntryPoint</entryPoint>
                </initialization>
                <transformations>
                    <transformation>
                        <plugin>net.bytebuddy.test.SimplePlugin</plugin>
                    </transformation>
                </transformations>
            </configuration>
        </plugin>
...

foo/bar.class：

package foo;
import javax.xml.bind.annotation.XmlAttribute;
public class Bar {
    @XmlAttribute(
        name = "qux"
    )
    public String qux;
    @XmlAttribute(
        name = "baz"
    )
    public String baz;
    public Bar() {
    }
}
