使用 jax2bMarshaller 在 spring mvc 上自动 marshalling/unmarshalling 验证

Question

在我的 spring mvc 项目中，我想解组和验证 xml 请求并编组和验证 xml 响应。现在在我的 spring 配置文件中我做了：

@Bean
    public MarshallingHttpMessageConverter marshallingMessageConverter() throws Exception {
        MarshallingHttpMessageConverter marshallingHttpMessageConverter = new MarshallingHttpMessageConverter();
        marshallingHttpMessageConverter.setMarshaller(jaxb2Marshaller());
        marshallingHttpMessageConverter.setUnmarshaller(jaxb2Marshaller());
        return marshallingHttpMessageConverter;
    }

    @Bean
    public Jaxb2Marshaller jaxb2Marshaller() throws Exception {
        Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
        marshaller.setClassesToBeBound(BillDataRequest.class);
        marshaller.setSchema(new ClassPathResource("file.xsd"));
        marshaller.setValidationEventHandler(new MyValidationEventHandler());
        marshaller.afterPropertiesSet();
        return marshaller;
    }

当在我的控制器中注入 jaxMarshaller 并调用 unmarshall 方法时，一切正常。有没有办法告诉 Spring 自动解组和验证请求？谢谢

Answer 1

您可以创建自己的拦截器。创建一个实现 HandlerInterceptor.

的 class

在您的 WebConfig 中将拦截器添加到方法中：

@Override
public void addInterceptors(InterceptorRegistry registry)

或者您可以使用 Spring AOP 来做到这一点。

Answer 2

您可以向 RequestMappingHandlerAdapter 提供转换器。将带有转换器的 RequestMappingHandlerAdapter 添加到您的 spring 配置文件：

@Bean
public RequestMappingHandlerAdapter requestMappingHandlerAdapter(MarshallingHttpMessageConverter marshallingHttpMessageConverter) {
    RequestMappingHandlerAdapter requestMappingHandlerAdapter = new RequestMappingHandlerAdapter();

    List<HttpMessageConverter<?>> messageConverters = new ArrayList<>();
    messageConverters.add(marshallingHttpMessageConverter);

    requestMappingHandlerAdapter.setMessageConverters(messageConverters);

    return requestMappingHandlerAdapter;
}
