org.springframework.messaging.converter.AbstractMessageConverter.<init>([Lorg/springframework/util/MimeType;)V春季云流

Question

当我简单地从：https://github.com/schacko-samples/s1p-2019-scst-kafka-talk/tree/master/hello-streams-application运行代码时，我得到了下面的错误。

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    org.springframework.cloud.function.context.config.JsonMessageConverter.<init>(JsonMessageConverter.java:47)

The following method did not exist:

    org.springframework.messaging.converter.AbstractMessageConverter.<init>([Lorg/springframework/util/MimeType;)V

The method's class, org.springframework.messaging.converter.AbstractMessageConverter, is available from the following locations:

    jar:file:/C:/Users/user/.m2/repository/org/springframework/spring-messaging/5.2.0.RELEASE/spring-messaging-5.2.0.RELEASE.jar!/org/springframework/messaging/converter/AbstractMessageConverter.class

It was loaded from the following location:

Action:

Correct the classpath of your application so that it contains a single, compatible version of org.springframework.messaging.converter.AbstractMessageConverter

Answer 1

看起来您在类路径上有错误的(不匹配的)spring消息版本。该方法是在Spring Framework 5.2.2中添加的。

我看到该项目的pom正在使用快照。

我认为Hoxton在SR5前后从Boot2.2切换到了2.3。

在pom中，尝试将Boot starter更改为2.3.9.RELEASE，将Hoxton版本更改为Hoxton.SR10。

如果这不起作用，可以尝试Boot2.2.13.RELEASE和Hoxton.SR4。
