Question

我已经使董事会需要使用Spring框架进行注册和登录。但我不知道为什么会出现HTTP 500错误。我真的是春天新手，我不知道该如何处理这个错误。

我正在使用spring / mvc / mybatis / oracle。

我创建了新的实例，例如：测试A = new Test（）; A.test（）;

围绕发生错误的代码。

但是我找不到什么具体值是空的。

错误（根本原因）：

            } 
            txManager.commit(status);

            txManager.rollback(status);
            System.out.println("데이터 저장 오류: " + ex.toString());
        }  
    }
}

BoardCtr.java:166

    /**
     * 회원 저장
     */
    @RequestMapping(value = "/gojoinPro")
    public String gojoinPro(HttpServletRequest request, MemberVO memberInfo) {
        memberSvc.insertMember(memberInfo);

        return "redirect:/boardList"; // 회원 가입 완료 페이지 만들기
    }

注册数据必须插入到oracleDB表中。但是不能。
