org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.builder.BuilderExce

为什么80%的码农都做不了架构师？>>> org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.builder.BuilderExce

那个方法这样写的：

List<Map<String,Object>> findAllUser(@Param("groupId")String groupId);

改过来：

List<Map<String,Object>> findAllUser(String groupId);

ok!

下面是控制台报错情况：

org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.builder.BuilderException: Error invoking SqlProvider method (org.yl.orm.mapper.FieldsPoolSqlProvider.findAllUser). Cause: java.lang.IllegalArgumentException: argument type mismatch
