Description:

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

    springfox.documentation.spring.web.scanners.ApiListingScanner.scan(ApiListingScanner.java:117)

The following method did not exist:

    com.google.common.collect.FluentIterable.append(Ljava/lang/Iterable;)Lcom/google/common/collect/FluentIterable;

The method's class, com.google.common.collect.FluentIterable, is available from the following locations:

    jar:file:/D:/maven/.m2/repository/com/google/guava/guava/16.0.1/guava-16.0.1.jar!/com/google/common/collect/FluentIterable.class

It was loaded from the following location:

    file:/D:/maven/.m2/repository/com/google/guava/guava/16.0.1/guava-16.0.1.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of com.google.common.collect.FluentIterable

　　

通过分析，排除16.0.1就可以了。

 

右击选择【Exclude】就可以了；

 

 

 再看就没有报错了。
