java - Axis2 的 wsdl2java 在 RPC/编码样式 Web 服务上失败

Question

是否有 Axis2 的替代方案？或者使其工作的方式(例如，不同的数据绑定(bind))？

注意:Apache CXF 也失败了 :(

Answer 1

我发现只有 3 个选项可以在 Java 中用于旧式 rpc/编码的 web 服务:

1) SUN对JAX-RPC的引用实现(wscompile)

2)WebLogic的clientgen(我用的是8.1版本)

3) Axis1 v1.4 wsdl2java

最初我们为此使用 Axis 1.4，它在相对较大的服务响应 (>20k) 上显示出相当差的性能，即与没有解析的普通 HTTP 请求相比，客户端处理时间增加了两倍多。如果响应变大，时间也会变长。仅反序列化 1MB 大响应就花了 30 多秒。

SUN 生成的客户端并没有真正工作，它根据请求失败并显示消息:

unexpected element name: 
   expected=getSubscriberInfoReturn, 
   actual={ws.generated.api}getSubscriberInfoReturn

我曾尝试使用 WebLogic 的 8.1 clientgen，并将客户端代码与 Axis 1.4 生成的客户端性能进行比较。 Axis 心国赢得了比赛。因此，即使 Axis 客户端在相对较大的响应上表现不佳，它仍然是旧 rpc/编码 Web 服务的最佳选择:(。
