我使用 jsonb 作为 Spring Boot 的首选 json 映射器。但是当通过 Rest 客户端（Soap UI）调用控制器时，我得到了一个 Stream closed 异常。如果我使用 Jackson 作为首选的 json 映射器，一切都会顺利进行。我正在使用 Spring WebMVC。没有 JAX-RS。我们正在尝试使用 Java 平台的标准 Json API。返回的对象是一个简单的 POJO，使用 lombok 注释 (@Data) 进行注释。jsonb 实现的其他用途在其他非 spring-mvc 方法中起作用。

代码/配置部分：

1) pom.xml

<dependency>
    <groupId>org.glassfish</groupId>
    <artifactId>javax.json</artifactId>
    <version>1.1.4</version>
</dependency>
<dependency>
    <groupId>javax.json.bind</groupId>
    <artifactId>javax.json.bind-api</artifactId>
    <version>1.0</version>
</dependency>
<dependency>
    <groupId>org.eclipse</groupId>
    <artifactId>yasson</artifactId>
    <version>1.0.4</version>
</dependency>

2）应用程序.yaml：

spring:
    application:
        name: spring-boot-jsonb-sample
    profiles:
        active: local
    http:
        converters:
            preferred-json-mapper: jsonb

3）控制器方法：

@PostMapping(value = "/resource", produces = APPLICATION_JSON_VALUE, 
consumes = APPLICATION_JSON_VALUE)
public Response method(@RequestBody @NotNull @Valid Request request) {
   return service.serviceMethod(request);
}

例外：

我尝试切换服务器：Jetty/Tomcat。我还尝试了不同的实现：Apache Johnzon vs Eclipse Yasson。

这也会影响带有最新版本 Yasson 1.0.6 的 Spring Boot 2.2.5。

这是 Yasson 和 Spring Boot 之间的错误。它正在 Yasson 方面得到解决，在这个问题中https://github.com/eclipse-ee4j/yasson/issues/389
