使用APT的Java Web服务。我是否需要注释处理器？哪里不对？ [英] Java Web service using Apt. Do I need an annotation processor? What is wrong?

问题描述

我一直在努力做一个简单的Web服务，并一直在关注本教程。不幸的是我坚持。以下是我迄今所做的：

I have been trying to make a simple web service and have been following this tutorial . Unfortunately I am stuck. Here is what I have done so far:

1）我创建这个类：

package server;

import javax.jws.WebService;

@WebService
public class HelloImpl {

  /**
   * @param name
   * @return Say hello to the person.
   */
   public String sayHello(String name) {
     return "Hello, " + name + "!";
   }
}

2）我跑：

apt HelloImpl.java

3）我得到这样的警告：

3) I get this warning:

hostName[username:~/Desktop/webtest][534]% apt HelloImpl.java
warning: Annotation types without processors: [javax.xml.bind.annotation.XmlRootElement, javax.xml.bind.annotation.XmlAccessorType, javax.xml.bind.annotation.XmlType, javax.xml.bind.annotation.XmlElement]
1 warning

贴切的命令应（按教程）生成以下文件：

The apt command should (according to the tutorial) produce these files:

HelloServiceImpl.wsdl
schema1.xsd
classes/server/HelloImpl.class
classes/server/jaxrpc/SayHello.class
classes/server/jaxrpc/SayHelloResponse.class
classes/server/jaxrpc/SayHello.java
classes/server/jaxrpc/SayHelloResponse.java

这是什么产生的，当我叫apt：

This is what was generated when I called apt:

HelloImpl.java (not generated but it is still in the directory)
HelloImpl.class
server/jaxws/SayHello.cass
server/jaxws/SayHell.java
server/jaxws/SayHelloResponse.class
server/jaxws/SayHelloResponse.java

（丢失：）

HelloServiceImpl.wsdl
schema1.xsd

（路径也略有不同）

(the paths are also slightly different)

我怀疑是正在生成警告并没有被生成的其他文件，因为我有的注解类型，而处理器。

I suspect that the warning is being generated and the other files are not being generated because I have "Annotation types without processors:".

我觉得警告意味着它需要一个注解厂（处理器）。我知道，你可以指定一个什么出厂：

I think that the warning indicates that it needs an annotation factory (processor). I know that you can specify what a factory by:

在此输入code -cp指定查找用户类文件和注释处理器工厂

enter code here-cp Specify where to find user class files and annotation processor factories

我只是不确定要指定的工厂。 （或者，也许我需要配置不同的东西）。

I am just unsure of what factory to specify. (Or maybe I need to configure something differently).

推荐答案

这是5岁的教程可能有点过时。 JAX-WS 是JAX-RPC的接班人。不过，也许你需要的是，而不是运行 WSGEN 工具APT的。

That 5 year old tutorial might be a bit out of date. jax-ws is the successor to jax-rpc. Though, maybe all you need is to run the wsgen tool instead of apt.
