Answer 1

BindingException: Mapper method 'com.yaoyao.pay.mapper.UserMapper.insertCompanyBank' has an unsupported return type: class java.lang.String

 

检查这个方法

Answer 2

BindingException: Mapper method 'com.yaoyao.pay.mapper.UserMapper.insertCompanyBank' has an unsupported return type: class java.lang.String

意思就是你的public String insertCompanyBank(@Param("user")User user ) throws Exception;这个方法不支持返回类型为String的，你可以改成int的试一试
