如何在Spring BOOT WS中返回MTOM

Question

我的 Spring Boot Soap 服务器有问题，我使用 Spring WS，我必须在附件中返回我的文件，我将一个数据处理器返回到 Jaxb 创建的 listtype，但我在 soap ui 中的响应中看到附件 0，并在 base64 中返回文件。 我不知道该怎么做。 你可以帮我吗。 非常感谢。

我的配置 Bean 是：

@Bean
public ServletRegistrationBean messageDispatcherServlet(ApplicationContext applicationContext) {
MessageDispatcherServlet servlet = new MessageDispatcherServlet();
servlet.setApplicationContext(applicationContext);
servlet.setTransformWsdlLocations(true);
return new ServletRegistrationBean(servlet, "/ws/services/*");
}
@Bean(name = "students")
public DefaultWsdl11Definition defaultWsdl11Definition(XsdSchema countriesSchema) {
DefaultWsdl11Definition wsdl11Definition = new DefaultWsdl11Definition();
wsdl11Definition.setPortTypeName("StudentPort");
wsdl11Definition.setLocationUri("/ws/services/test");
wsdl11Definition.setTargetNamespace("http://www.example.org/demo/");
wsdl11Definition.setSchema(countriesSchema);
Properties props = new Properties();
props.put("getDemo", "http://www.example.org/demo/getDemoRequest");
wsdl11Definition.setSoapActions(props);
return wsdl11Definition;
}
@Bean
public XsdSchema countriesSchema() {
return new SimpleXsdSchema(new ClassPathResource("/it/xsd/demo.xsd"));
}

我的端点只有以下注释：

@PayloadRoot(namespace = NAMESPACE_URI, localPart = "getDemoRequest")
@ResponsePayload

在我的demo.xsd中，我设置了文件类型

<element name="fileType" type="base64Binary" maxOccurs="unbounded" xmime:expectedContentTypes="application/octet-stream">

我现在还没有 xml 配置，如果不需要完美的 Spring 启动风格，我不想使用任何 xml。

非常感谢。

向上： 我的代码尝试启用 MTOM。

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.oxm.jaxb.Jaxb2Marshaller;
import org.springframework.ws.config.annotation.WsConfigurerAdapter;
import org.springframework.ws.server.endpoint.adapter.method.MarshallingPayloadMethodProcessor;
import org.springframework.ws.server.endpoint.adapter.method.MethodArgumentResolver;
import java.util.List;
@Configuration
public class MTOMEnable extends WsConfigurerAdapter {
@Override
public void addArgumentResolvers(List<MethodArgumentResolver> argumentResolvers) {
argumentResolvers.add(methodProcessor());
}
@Bean
public Jaxb2Marshaller marshaller() {
Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
marshaller.setClassesToBeBound(GetStudentsResponse.class);
marshaller.setMtomEnabled(true);
return marshaller;
}
@Bean
public MarshallingPayloadMethodProcessor methodProcessor() {
return new MarshallingPayloadMethodProcessor(marshaller());
}
}

Answer 1

问题是 DefaultMethodEndpointAdapter bean 将启用 MTOM 的 JAXB 编组器/解组器添加到处理程序列表的 END 中。 诀窍是覆盖 DefaultMethodEndpointAdapter bean 并将它们放在第一位。 这样你甚至不需要覆盖addArgumentResolvers((。

以下是 Kotlin，但应该很容易转换为纯 Java。

@Bean
override fun defaultMethodEndpointAdapter() = object: DefaultMethodEndpointAdapter() {
override fun initDefaultStrategies() {
super.initDefaultStrategies()
methodArgumentResolvers.add(0, methodProcessor()) // needs to be FIRST in list
methodReturnValueHandlers.add(0, methodProcessor()) // needs to be FIRST in list
}
}

您还需要确保相关的@RequestPayload和返回参数是 JAXBELement<...>
