nested exception is org.apache.ibatis.builder.BuilderException Error invoking SqlProvider method

在同时使用通用 Mapper 和 PageHelper 的情况下,需要将 PageHelper 插件放在前面,通用mapper 配置在后边,否则将抛出以下异常

org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.builder.BuilderException: Error invoking SqlProvider method (com.github.abel533.mapper.MapperProvider.dynamicSQL).  Cause: java.lang.InstantiationException: com.github.abel533.mapper.MapperProvider

正确配置应该如下所示
