反序列化错误春季启动反应

问题描述：

@RestController 
@RequestMapping("path") 
public class MyController { 

    @PostMapping(consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.APPLICATION_JSON_VALUE) 
    public Flux<SomeObject> run(@RequestBody Flux<RequestObject> request){ 

     //do something and return flux 
    } 
    ... 
}

在调用这个网址我得到异常

"Type definition error: [simple type, class reactor.core.publisher.Flux]; nested exception is com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Can not construct instance of reactor.core.publisher.Flux (no Creators, like default construct, exist): abstract types either need to be mapped to concrete types, have custom deserializer, or contain additional type information\n at [Source: (PushbackInputStream); line: 1, column: 1]

我明白了这个错误，通常，我只想补充一个注释如果需要

@JsonDeserialize(as = SomeConcreteClass.class)

但是在这种情况下，我应该绑定Flux具体示例？另外，Spring boot是否具有用于反应堆类型（单声道，通量）的默认自动解串器？

我POM（相关的东西）：

<dependency> 
     <groupId>org.springframework.boot</groupId> 
     <artifactId>spring-boot-starter-web</artifactId> 
    </dependency> 
    <dependency> 
     <groupId>org.springframework.boot</groupId> 
     <artifactId>spring-boot-starter-webflux</artifactId> 
    </dependency> 
    <dependency> 
     <groupId>org.springframework.data</groupId> 
     <artifactId>spring-data-commons</artifactId> 
    </dependency>

答

你实际上是在使用Spring MVC现在。

删除spring-boot-starter-web并确保没有其他依赖项能够传递它。
