Answer 1

Failed to convert from type java.util.ArrayList<?> to type java.util.List for value '[/WEB-INF/static/]'; nested exception is org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type java.lang.String to type org.springframework.core.io.Resource

翻译一下：
不能从类型 java.util.ArrayList<?> 到 java.util.List型。列表值“[/WEB-INF/static/]”;
转换器没有发现异常:没有发现转换器能将从类型 String .org.springframework.core.io.Resource

我估计是你spring配置文件错了，，发出来捋一捋
