＆＃34;创建bean＆＃34;时出错在Hibernate中使用Spring

标签： spring hibernate maven beancreationexception

我正在使用一个也使用Maven的Spring with Hibernate项目。我正在尝试创建一个页面，其中包含一个表单来捕获搜索信息以及显示结果。我已经创建了dispatcher-servlet，web.xml，控制器，模型和视图，但是当我尝试在服务器上运行项目时，我收到以下500错误：

  

Servlet调度程序的Servlet.init（）抛出异常（下面的堆栈跟踪和文件）。

我有点困惑，因为我正在关注一个教程，我相信我的所有依赖都是正确的。我已经看过堆栈跟踪，从我读过的内容看来，似乎存在版本控制问题。我尝试在pom.xml文件中更改我的版本，但没有运气。我还检查了WEB-INF/lib文件夹，我有hibernate-core以及其他必需的jar，所以我认为pom.xml配置正确。

根据我对Spring的理解，dispatcher-servlet应该注入sessionFactory bean，但它似乎没有正常工作。我想如果我能够通过sessionFactory问题，我就能继续前进。

pom.xml （我不太确定我的相关性是否正确。）

StudentController.java （我计划将此作为应用程序的主控制器使用）

package com.yccd.controllers;

import java.util.Map;

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import com.yccd.model.Student;

@Controller
@RequestMapping(value = "/student")
public class StudentController {

@RequestMapping(value = "/showAll", method = RequestMethod.GET)
public String sayHelloAgain(@PathVariable("queryType") String queryType,     
ModelMap model) {
        model.addAttribute("message", "Just to say hello again");
        model.addAttribute("queryTypeChoice", queryType);
        return "welcomeAgain";
    }

    @RequestMapping(value = "/searchResults", method = RequestMethod.GET)
    public String displayStudents(ModelMap model) {
        return "displayStudentRecords";
    }

    @RequestMapping(value = "/search", method = RequestMethod.POST)
    public String search(Student student, Map<String, Object> map) {
        //TO-DO: GET PARAM VALUES AND MAKE A CALL TO SERVICE LAYER HERE
        return "displayStudentRecords";
    }
}

displayStudentRecords.jsp （这是我要显示从数据库中获取的记录的页面）

我是Spring，Hibernate和Maven的新手。如果这看起来微不足道，我很抱歉。

这只是堆栈跟踪的一部分。我不太擅长从查看堆栈跟踪来确定问题是什么，所以如果有一些指针你可以给我，比如首先要查看它的哪一部分，或者我是否会有任何区域能够忽略，这也是非常有用的。

堆栈跟踪 

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping': Invocation of init method failed; nested exception is org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [org.springframework.orm.hibernate5.LocalSessionFactoryBean] for bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/dispatcher-servlet.xml]; nested exception is java.lang.ClassNotFoundException: org.springframework.orm.hibernate5.LocalSessionFactoryBean

相关原因：

org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [org.springframework.orm.hibernate5.LocalSessionFactoryBean] for bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/dispatcher-servlet.xml]; nested exception is java.lang.ClassNotFoundException: org.springframework.orm.hibernate5.LocalSessionFactoryBean

您错过了一些Spring依赖项。 尝试使用这些（将正确的版本标记添加到依赖项）：

<%= form_with(model: @user, local: true) do |f| %>
    <div>
        <%= f.label :name %>
        <%= f.text_field :name %>
    </div>

    <div>
        <%= f.label :email %>
        <%= f.email_field :email %>
    </div>
    <%= f.submit %>
<% end %>
