上传文件时 java 休息服务上的 415 不支持的媒体类型

Question

我正在尝试建立一个休息服务来上传文件。这是我得到的。当我在 postman 中进行测试时，我选择了表单数据并将 "file" 设置为我正在上传的文件。

@POST
@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response upload(@RequestParam("file") MultipartFile file)

我的理解是我需要 jersey-media-multipart 依赖项

<dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-multipart</artifactId>
    <version>2.25.1</version>
</dependency>

当我尝试发出 post 请求时，出现 415 Unsupported Media Type 错误，我不确定原因。设置为消费MULTIPART_FORM_DATA，参数为MultipartFile.

编辑我添加了如下配置，

@Configuration
public class JerseyConfig extends ResourceConfig {
    public JerseyConfig() {
        register(MultiPartFeature.class);
    }
}

我也修复了我的资源

@POST
@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response upload(
        @FormDataParam("file") InputStream file,
        @FormDataParam("file") FormDataContentDisposition fdcd,
        @FormDataParam("file-detail") String fileDetail) throws IOException {

现在我得到 [[FATAL] No injection source found for a parameter of type public javax.ws.rs.core.Response

这是我的 spring 引导 class，其中包含其他配置

    @SpringBootApplication
@EnableCircuitBreaker
@EntityScan("com.whatever.")
@ImportResource({"classpath*:/META-INF/**/spring-bootstrap.xml"})
@Import({JerseyConfig.class})
@EnableJpaRepositories(basePackages="whatever", entityManagerFactoryRef="entityManagerFactory")
public class Application {

protected TomcatEmbeddedServletContainerFactory createTomcatEmbeddedServletContainerFactory() {
        return new TomcatEmbeddedServletContainerFactory() {

            @Override
            protected TomcatEmbeddedServletContainer getTomcatEmbeddedServletContainer(Tomcat tomcat) {
                ((StandardHost) tomcat.getHost()).setErrorReportValveClass(StringUtils.EMPTY);
                return super.getTomcatEmbeddedServletContainer(tomcat);
            }
        };
    }

    @Bean
    public FilterRegistrationBean requestContextFilter() {
        FilterRegistrationBean filterRegistration = new FilterRegistrationBean(new org.springframework.web.filter.RequestContextFilter());
        filterRegistration.setName("RequestContextFilter");
        filterRegistration.setOrder(Ordered.HIGHEST_PRECEDENCE + 1);
        filterRegistration.addUrlPatterns(BASE_PATH + "*");
        return filterRegistration;
    }    

    @Bean 
    public FilterRegistrationBean springSecurityFilterChain() {
        FilterRegistrationBean filterRegistration = new FilterRegistrationBean(new org.springframework.web.filter.DelegatingFilterProxy());
        filterRegistration.setName("SpringSecurityFilterChain");
        filterRegistration.setOrder(Ordered.HIGHEST_PRECEDENCE + 2);
        filterRegistration.addUrlPatterns(BASE_PATH + "*");
        return filterRegistration;
    }

    @Bean
    @Conditional(NonWindowsCondition.class)
    public FilterRegistrationBean f5Filter() {
        FilterRegistrationBean filterRegistration = new FilterRegistrationBean(new F5Filter());
        filterRegistration.setName("F5Filter");
        filterRegistration.setOrder(Ordered.HIGHEST_PRECEDENCE + 3);
        filterRegistration.addUrlPatterns(BASE_PATH + "*");
        return filterRegistration;
    }

        jerseyFilterRegistration.setDispatcherTypes(EnumSet.allOf(DispatcherType.class));

        jerseyFilterRegistration.addInitParameter("jersey.config.servlet.filter.forwardOn404", "true");

        if (isJerseyDebug) {
            // Debug parameter switches
            jerseyFilterRegistration.addInitParameter("jersey.config.server.monitoring.statistics.enabled", "true");
            jerseyFilterRegistration.addInitParameter("jersey.config.server.tracing.type", "ALL");
            jerseyFilterRegistration.addInitParameter("jersey.config.server.tracing.threshold", "VERBOSE");
        }

        return jerseyFilterRegistration;
    }

@RequestParam 和 MultipartFile 都是 Spring 而不是泽西岛的东西。对于 Jersey，您要使用的是注释 @FormDataParam，对于参数，根据部件类型，您可以使用许多不同类型的参数。如果该部分是一个文件，您可以使用 InputStream、File 或 byte[] 参数，或者如果该部分是一些纯文本，您可以使用 String 参数。如果需要文件名，可以添加一个 FormDataContentDisposition 参数以及零件实体参数。下面是一个例子

@POST
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response upload(
        @FormDataParam("file") InputStream file,
        @FormDataParam("file") FormDataContentDisposition fdcd,
        @FormDataParam("file-detail") String fileDetail) {

}

要完成这项工作，您需要在您的应用程序中注册 MultiPartFeature。您可以查看了解注册方法。
