在我的反应性REST API中,我试图返回一个XML
响应。但是,我总是得到一个JSON
,即406 NOT_ACCEPTABLE
。知道为什么吗?
@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
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'
}
这些是我的REST controller和unit test的链接。谢谢!
答案 0 :(得分:2)
显然,jackson-dataformat-xml
does not yet支持WebFlux中的XML编组。到目前为止,我看到了两种可能性:
org.springframework.boot:spring-boot-starter-web
(应该同时有 starter-web 和 starter-webflux )。但是,这仅适用于Servlet 3.1运行时(例如Tomcat)。Jaxb2XmlEncoder
和Jaxb2XmlDecoder
开始的JAXB编组的use xml: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
不需要这些依赖项)和@XmlRootElement
批注。该解决方案可以立即生效,但是,如果您要进一步定制,请实施自己的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
}
}
