我试图从Spring RestController返回一个Observable,但没有成功。我的代码如下:
@RestController
public class HystrixCommentController {
@GetMapping(value = "/com1/{id}")
public Observable<Comment> getComment1(@PathVariable int id) {
return Observable.just(new Comment());
}
}
在邮递员中运行请求时,总是出现以下错误:
{
"timestamp": "2018-07-08T16:07:36.809+0000",
"status": 500,
"error": "Internal Server Error",
"message": "No converter found for return value of type: class rx.internal.util.ScalarSynchronousObservable",
"path": "/com1/1"
}
SpringBoot 2还不支持rx。在RestController中可观察到 就像使用Mono / Flux一样?
我需要手动将Observable转换为Mono / Flux吗?
致谢
注意:pom中包含spring-boot-starter-webflux
我尝试过这个:
@RestController
public class HystrixCommentController {
@GetMapping(value = "/com1/{id}", produces = "application/json")
public Observable<Comment> getComment1(@PathVariable int id) {
return Observable.just(new Comment());
}
}
没有成功:
{
"timestamp": "2018-07-08T18:21:42.918+0000",
"status": 406,
"error": "Not Acceptable",
"message": "Could not find acceptable representation",
"path": "/com1/1"
}
答案 0 :(得分:2)
所以这里的问题是我的pom.xml中缺少依赖项:
<dependency>
<groupId>io.reactivex</groupId>
<artifactId>rxjava-reactive-streams</artifactId>
<version>1.2.1</version>
</dependency>
