我试图设置一个简单的spring + hibernate项目，但不断获得以下堆栈跟踪......我也在下面粘贴了我的pom配置。

我的servlet-context.xml，我不确定这是否会导致任何错误：

<?xml version="1.0" encoding="UTF-8"?>
<mvc:annotation-driven />
<mvc:resources mapping="/resources/**" location="/resources/" />
<context:component-scan base-package="com.package.spring" />

<bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close">
    <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
    <property name="url" value="jdbc:mysql://localhost:3306/db"/>
    <property name="username" value="root"/>
    <property name="password" value="root"/>
</bean>
<bean id="sessionFactory"
    class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="configLocation" value="classpath:hibernate.cfg.xml" />
</bean>
<tx:annotation-driven />
<bean id="transactionManager"
    class="org.springframework.orm.hibernate5.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>

 Injects DAO into spring controller  
<bean id="userDAO" class="com.package.dao.userDAO">
    <constructor-arg>
        <ref bean="sessionFactory" />
    </constructor-arg>
</bean>

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/webapp/views/" />
    <property name="suffix" value=".jsp" />
</bean>

我花了太多时间试图让它发挥作用......

首先你的pom有点乱。使用spring-boot-starter项目而不是单个jar。 

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>

     <!-- http://mvnrepository.com/artifact/mysql/mysql-connector-java -->
     <dependency>
         <groupId>mysql</groupId>
         <artifactId>mysql-connector-java</artifactId>
     </dependency>

</dependencies>

应该是你所需要的一切。我想要一个特定版本的hibernate使用hibernate.version属性。

<properties>
    <hibernate.version>5.2.0.Final</hibernate.version>
</properties>

注意： Spring（Boot）尚不适用于hibernate 5.2！

接下来删除Spring xml配置文件。

将数据库的凭据放在application.properties中，而不是普通的hibernate使用JPA代替。

另外在你的pom中删除了程序集插件，因为Spring Boot Plugin已经处理了这个问题，而程序集插件生成了一个错误的jar文件。
