在春季启动中无法访问WSDL端点

Question

我创建了一个Spring Boot SOAP Web服务：接受两个数字并显示它们的加法。

我无法访问WSDL端点：错误是“标准化白色标签”页面。

代码和pom.xml文件如下：

pom.xml：

EndPoint Java类：

package com.example.operations.endpoint;

import org.springframework.ws.server.endpoint.annotation.Endpoint;
import org.springframework.ws.server.endpoint.annotation.PayloadRoot;
import org.springframework.ws.server.endpoint.annotation.RequestPayload;
import org.springframework.ws.server.endpoint.annotation.ResponsePayload;
import com.example.operations.OperationsRequest;
import com.example.operations.OperationsResponse;

@Endpoint
public class OperationsEndPoint
{
    @PayloadRoot(namespace = "http://example.com/operations", localPart = "OperationsRequest")
    @ResponsePayload
    public OperationsResponse performOperations(OperationsRequest request)
    {
        OperationsResponse response = new OperationsResponse();
        int num1 = request.getNumber1();
        int num2 = request.getNumber2();
        response.setNumber1(num1);
        response.setNumber2(num2);
        response.setResult(num1 + num2);
        response.setOperationtype("add");

        return response;
    }
}

配置Java类：

package com.example.operations.config;

import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.ClassPathResource;
import org.springframework.ws.config.annotation.EnableWs;
import org.springframework.ws.transport.http.MessageDispatcherServlet;
import org.springframework.ws.wsdl.wsdl11.DefaultWsdl11Definition;
import org.springframework.xml.xsd.SimpleXsdSchema;
import org.springframework.xml.xsd.XsdSchema;


@EnableWs
@Configuration
public class WebServiceConfig {

  @Bean
  public ServletRegistrationBean messageDispatcherServlet(ApplicationContext context) {
    MessageDispatcherServlet messageDispatcherServlet = new MessageDispatcherServlet();
    messageDispatcherServlet.setApplicationContext(context);
    messageDispatcherServlet.setTransformWsdlLocations(true);
    return new ServletRegistrationBean(messageDispatcherServlet, "/ws/*");
  } 

  @Bean(name = "operations")
public DefaultWsdl11Definition defaultWsdl11Definition(XsdSchema schema) {
  DefaultWsdl11Definition definition = new DefaultWsdl11Definition();
  definition.setPortTypeName("OperationsPort");
  definition.setTargetNamespace("http://example.com/operations");
  definition.setLocationUri("/ws");
  definition.setSchema(schema);
  return definition;
}

@Bean
public XsdSchema schema() {
  return new SimpleXsdSchema(new ClassPathResource("operations.xsd"));
}
}

让我知道我在哪里犯错误。我正在使用以下命令执行应用程序：

mvn spring-boot:run
