Question

我正在使用Gson编写一些我写的Jayway代码：

private static final Configuration JACKSON_CONFIGURATION = Configuration
        .builder()
        .mappingProvider(new GsonMappingProvider())
        .jsonProvider(new GsonJsonProvider())
        .build();

但是当我运行它时（尝试应用一些标准来选择JSON中的元素），发生了以下异常：

似乎正在查找一些net.minidev类。有线索吗？

Answer 1

将net.minidev.json-smart添加到类路径中如果需要，将net.mimidev.asm添加到类路径

当我使用Gson时，Jayway正在查找net.minidev类
