SpringBoot Webflux无法返回application/xml [英] SpringBoot Webflux cannot return application/xml
问题描述
在我的反应性REST API中,我试图返回XML
响应.但是,我总是得到一个JSON
,即406 NOT_ACCEPTABLE
.知道为什么吗?
In my reactive REST API I'm trying to return an XML
response. However, I always get a JSON
, namely 406 NOT_ACCEPTABLE
. Any idea why?
@RestController
@RequestMapping(path = "/xml", produces = APPLICATION_XML_VALUE)
public class RestApi {
@GetMapping(path = "/get")
public Publisher<ResponseEntity> get() {
return Mono.just(ResponseEntity.ok().contentType(APPLICATION_XML).body(new Datta("test")));
}
@PostMapping(path = "/post", consumes = APPLICATION_XML_VALUE)
public Publisher<ResponseEntity<Datta>> post(@RequestBody Datta datus) {
datus.setTitle(datus.getTitle() + "!");
return Mono.just(ResponseEntity.ok().contentType(APPLICATION_XML).body(datus));
}
}
java.lang.AssertionError: 预期的:application/xml 实际:application/json; charset = UTF-8
java.lang.AssertionError: Expected :application/xml Actual :application/json;charset=UTF-8
plugins {
id 'org.springframework.boot' version '2.1.3.RELEASE'
id "io.spring.dependency-management" version "1.0.7.RELEASE"
}
dependencies {
implementation 'org.springframework.boot:spring-boot-starter-webflux'
implementation "com.fasterxml.jackson.dataformat:jackson-dataformat-xml:2.9.8"
testImplementation 'org.springframework.boot:spring-boot-starter-test'
}
这些是指向我的REST的链接单元测试.谢谢!
These are the links to my REST controller and a unit test. Thanks!
推荐答案
Apparently, jackson-dataformat-xml
does not yet support XML Marshalling in WebFlux. As for now I see two possibilities:
- 在类路径上添加
org.springframework.boot:spring-boot-starter-web
(应该同时存在 starter-web 和 starter-webflux ).但是,这仅适用于Servlet 3.1运行时(例如Tomcat). - 或者如果您需要功能完善的反应式Web服务器(例如Netty)
- Either add
org.springframework.boot:spring-boot-starter-web
on the classpath (there should be both starter-web and starter-webflux). However, this will only work with Servlet 3.1 runtimes (e.g. Tomcat). - Or if you want a fully fledged reactive web server (e.g. Netty) use xml marshalling from JAXB (
Jaxb2XmlEncoder
andJaxb2XmlDecoder
):
build.gradle :
sourceCompatibility = '11'
dependencies {
implementation 'org.springframework.boot:spring-boot-starter-webflux'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
// Java 11 removed these Java EE modules
implementation "javax.xml.bind:jaxb-api:2.3.1"
implementation "com.sun.xml.bind:jaxb-core:2.3.0.1"
implementation "com.sun.xml.bind:jaxb-impl:2.3.2"
compileOnly "org.projectlombok:lombok"
annotationProcessor "org.projectlombok:lombok"
}
POJO :
@Data
@AllArgsConstructor
@NoArgsConstructor
@XmlRootElement
public class Datta {
private String title;
}
注意3个javax.xml.bind
依赖项(Java 8
不需要这些)和@XmlRootElement
批注.该解决方案可以立即生效,但是,如果您想要进一步的自定义,请实施自己的WebFluxConfigurer
:
Mind the 3 javax.xml.bind
dependencies (you don't need these for Java 8
) and the @XmlRootElement
annotation. This solution works right away, however if you want further customization, implement your own WebFluxConfigurer
:
@Configuration
@EnableWebFlux
public class WebConfig implements WebFluxConfigurer {
@Override
public void configureHttpMessageCodecs(ServerCodecConfigurer configurer) {
configurer.registerDefaults(false);
configurer.customCodecs().decoder(new Jaxb2XmlDecoder()); // <- here
configurer.customCodecs().encoder(new Jaxb2XmlEncoder()); // <- here
}
}
