Question

我有一个基于spring框架的服务我想知道为什么我有这个例外，虽然我发送一个整数到我的服务

错误[io.undertow.request]（默认任务-13）UT005023：异常处理/ updateUserAnswer / 11的请求： org.lightadmin.core.view.exceptions.BadRequestException： org.springframework.web.util.NestedServletException：Request 处理失败;嵌套异常是 java.lang.IllegalArgumentException：参数值[11]不匹配期望的类型[java.lang.Integer（n / a）]

这是我的控制器

@RequestMapping(value = "/updateUserAnswers/{userId}", method = RequestMethod.PUT)
    public Response updateUserAnswer(@PathVariable("userId") Long userId,
            @RequestBody @Valid UserAnswer userAnswer) {

        userAnswerService.updateUserAnswer(userId, userAnswer);

        HashMap<String, Object> response = new HashMap<>();
        response.put("messages", null);
        response.put("success", Boolean.valueOf(true));
        return Response.instance().friendlyName("user-answer-updated").object(response).statusCode(HttpStatus.OK);
    }

这是我的服务：

public void updateUserAnswer(Long userId,UserAnswer userAnswer) {

    List<UserAnswer> currentUserAnswer = userAnswerRepo.getUserAnswers(userId, userAnswer.getAnswerId().longValue(),null);
    currentUserAnswer.get(0).setLabel(userAnswer.getLabel());       

    List<UserAnswerField> fieldsList =  new ArrayList<UserAnswerField>();


    for (UserAnswerField userAnswerField : userAnswer.getAnswerFields()) {
        UserAnswerField currentUserAnswerField = userAnswerFieldRepo.getUserAnswerField(userAnswerField.getfieldId());
        if (currentUserAnswerField != null) {
            currentUserAnswerField.setfield(userAnswerField.getfield());
            currentUserAnswerField.setTypeId(userAnswerField.getTypeId());
            fieldsList.add(currentUserAnswerField);
            //userAnswerFieldRepo.save(currentUserAnswerField);
        }           
    }   
    currentUserAnswer.get(0).setAnswerFields(fieldsList);

    userAnswerRepo.save(currentUserAnswer.get(0));
}

存储库：

public List<UserAnswer> getUserAnswers(Long userId,Long answerId ,String pageType) {
    try {
        String qlString = ""
                + " Select sf from UserAnswer sf "
                + " where "
                + " sf.userId = :userId ";
        if(pageType != null){
            qlString+= " and  sf.type=:type ";
        }
        if(answerId != null){
            qlString+= " and sf.answerId=:answerId ";
        }
        qlString+=" order by sf.insertionDate";

        Query query = getEntityManagerFactory().createQuery(qlString);
        query.setParameter("userId", userId);
        if(pageType != null){
            query.setParameter("type", pageType);
        }
        if(answerId != null){
            query.setParameter("answerId", answerId);
        }
        return (List<UserAnswer>) query.getResultList();
    } catch (javax.persistence.NoResultException e) {
        return null;
    }
}

你可以帮帮我吗？提前谢谢

Answer 1

错误发生在query.setParameter("userId", userId);，因为当hqlQuery期待一个Integer时你正试图设置一个Long。

解决方案：

更改类型Long - ＆gt; Integer从控制器到存储库
使用.intValue()（更多快速解决方案而不是解决方案）
将实体中的ID更改为Long类型。

Answer 2

您会收到异常，因为您需要绑定基本类型。

试试这个：

 public Response updateUserAnswer(@PathVariable("userId") long userId,
             @RequestBody @Valid UserAnswer userAnswer) { [...] }

与预期类型弹簧框架错误
