Java 生成 WSDL 但无法使用 ?wsdl 访问它

Question

我需要我的 Web 服务类返回一个包含以下客户类的数组，该类本身有一个数组。

创建 Web 服务时，将创建 wsdl，但是当我尝试使用其 url 访问它时，它显示以下错误。

添加 ?wsdl 到地址时会显示以下错误

轴错误

无法生成 WSDL！

此位置没有 SOAP 服务

当我不添加 ?wsdl 到地址时会显示以下错误

AXIS error

No service is available at this URL

我的客户类

package myclasses;

public class customer {
private String name;
private int age;
private int[] rankings;

public customer(){
    //Any initializations here.
}

public customer(String n, int a) {
    this.name = n;
    this.age = a;
    rankings = new int[2];
    rankings[0] = 1;
    rankings[1] = 2;

}

public String getName() {
    return name;
}

............Rest of setter and getters goes here .............

}

我的网络服务类

     package services;

import myclasses.customer;

import javax.jws.WebService;
import javax.jws.WebMethod;
import javax.jws.WebResult;
import javax.jws.soap.SOAPBinding; 

@WebService (name="Hellos", 
targetNamespace="http://localhost:8081/Mywebservice2/services/Hellos")  
@SOAPBinding  
(  
      style = SOAPBinding.Style.RPC,  
      use = SOAPBinding.Use.LITERAL,  
      parameterStyle = SOAPBinding.ParameterStyle.WRAPPED  
 )  
public class Hellos {

    @WebMethod
    public @WebResult(name="name",partName="name") String getName(){
        return "Jack";
    }
    
    @WebMethod
    public @WebResult (name="customers",partName="customers") customer[] mycustomers() {
        customer[] cus = new customer[2];
        cus[0] = new customer("Jack", 28);
        cus[1] = new customer("Alex", 29);
        return cus;
        
    }
}

Answer 1

通过服务类“services.Hellos”使用的值类型“myclasses.customer”没有公共默认构造函数

只需在客户类中使用它即可。

public customer()
{
  //Any initializations here.
}

Answer 2

在你的网络服务定义中试试这个

@SOAPBinding
(
style = SOAPBinding.Style.DOCUMENT,
use = SOAPBinding.Use.LITERAL,
parameterStyle = SOAPBinding.ParameterStyle.WRAPPED
) 

Answer 3

我最近遇到了同样的问题。

解决方案：在我的例子中，我使用的是 Axis 1.4，并且正在将应用程序部署在 tomcat 上。但是，由于某种原因，生成的 server-config.wsdd 没有在战争中打包，因此没有部署在 tomcat 上。有一次，我确保发生这种情况，它开始对我正常工作。
