尝试使用 CDI 扩展事件ProcessAnnotatedType
来更改@javax.ws.rs.Path
JAX-RS 资源。
<X> void process(@Observes ProcessAnnotatedType<X> pat) {
if (!pat.getAnnotatedType().isAnnotationPresent(javax.ws.rs.Path.class)) {
return;
}
final AnnotatedType<X> org = pat.getAnnotatedType();
AnnotatedType<X> wrapped = new AnnotatedType<X>() {
@Override
public <T extends Annotation> T getAnnotation(final Class<T> annotation) {
if (javax.ws.rs.Path.class.equals(annotation)) {
class PathLiteral extends AnnotationLiteral<javax.ws.rs.Path> implements javax.ws.rs.Path {
@Override
public String value() {
return "change_me/" + (javax.ws.rs.Path) org.getAnnotation(annotation);
}
}
return (T) new PathLiteral();
} else {
return org.getAnnotation(annotation);
}
}
pat.setAnnotatedType(wrapped);
}
...然后在引导之后,使用构建 beanjavax.enterprise.inject.spi.BeanManager
期望以下代码打印“change_me/....”
Set<Bean<?>> beans = beanManager.getBeans(jaxrsClass);
for (Bean<?> bean : beans) {
CreationalContext cc = bm.createCreationalContext(bean);
Object jaxrs = bean.create(cc);
Path p = jaxrs.getClass().getAnnotation(Path.class);
System.out.println(p.value());
}
...但这不起作用。javax.ws.rs.Path
对于 JAX-RS 资源 'jaxrsClass' 保持不变。
怎么了?
