문제

There was an unexpected error (type=Internal Server Error,
status=500).

Mapper method 
'com.example.mapper.MemberMapper.MemberUpdateAddrAction' has an 
unsupported return type: class com.example.dto.MemberAddrDTO

org.apache.ibatis.binding.BindingException: Mapper method 
'com.example.mapper.MemberMapper.MemberUpdateAddrAction' has an 
unsupported return type: class com.example.dto.MemberAddrDTO

@Update({
"UPDATE MEMBERADDR SET UADDRESSS = #
{memberaddr.uaddresss},UPOSTCODE=#{memberaddr.upostcode} 
WHERE UCODE=#{memberaddr.ucode} AND UEMAIL= #{memberaddr.uemail}"

        })
        
        public int MemberUpdateAddrAction(
        
                        @Param(value = "memberaddr") MemberAddrDTO 
                        memberaddr);

업데이를 하고 나서 리턴 타입을 MEMBERADDR로 받아서 발생하는 문제.

문제해결

UPDATE MEMBERADDR에서 UPDATE INT로 바꿔서 문제 해결
