Question

我现在正在使用axis2并使用Eclipse生成一个Web服务项目。现在我遇到了麻烦。

Java文件：

public class WebServiceServer{

public Map<String,String> getConfigInfo(List<Map<String,Object>> objectList){
    Map<String,String> returnMap = new HashMap<String, String>();

    try {
        //do something
    } catch (ConfigurationException e) {
        e.printStackTrace();
    } 
    return returnMap;
}

}

我现在正在使用Eclipse Java EE 3.6，我喜欢wtp插件。现在，我使用Eclipse并右键单击我的项目，然后单击New - ＆gt; Other - ＆gt; Web Service。

但是当我启动tomcat时，错误已经到来。

 Someone told me that axis2 cannot deal with the return type is List or Map?
 Any replay is welcome. Thanks.

Answer 1

正如上面的答案中所解释的，只有Axis2 Trunk版本（1.7.0-SNAPSHOT）支持列表，地图等集合。

除非您使用的是Axis2 trunk版本（1.7.0-SNAPSHOT），否则无法使用它们。您必须将Arrays与其他版本的Axis2一起使用。

谢谢和问候，

Answer 2

有人告诉我，axis2无法处理返回类型是List还是地图吗？

有人是对的。

您需要返回数组，或者在您的情况下，返回数组数组。
