Tomcat日志错误：java.lang.NoSuchMethodException:int.<；初始化>；（）在我的SpringMVC项目中

我的项目调查问卷是基于jdk1.8 tomcat8开发的，在我的本地机器上运行正常。没有发现错误。但是当我将它部署到服务器上时，项目有时运行正常，有时运行异常。如果运行异常，我将重新启动tomcat，然后它将变为正常。我没有找到原因，我从tomcat日志中得到的唯一消息如下：

[http-nio-80-exec-3] org.apache.catalina.core.StandardWrapperValve.invoke Servlet.service() for servlet [dispatcherServlet] in context with path [/questionnaire] threw exception [Request processing failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [int]: No default constructor found; nested exception is java.lang.NoSuchMethodException: int.<init>()] with root cause

服务器的环境是JDK1.8Tomcat8，类似于我的本地机器。有人帮我吗？非常感谢

我认为控制器方法上的模型没有args构造方法，因此创建失败。请再次检查。

在配置中的某个地方，您似乎用

@Autowired

标记了一个

int

变量。您的意思是我应该添加：Profile.java和Mood.java中没有args构造方法，公众形象（）{}和公众情绪（）{}但我有点困惑。在这两个java文件中，我没有添加自定义构造方法，所以默认构造函数是no-args，不需要我添加它manually@nicoleljc1227你能告诉我你的QQ号码吗？我会帮你的。对不起，我刚才在你的日志上看到一个答案，你想实例化int。那不是一个类。所以在你关于“调查问卷”的请求中没有构造方法
