使用JPA使用Hibernate配置SpringMVC

有人能告诉我我做错了什么吗。我所要做的就是使用SpringMVC和JPA配置访问mysql数据库。每次运行程序时，我都会遇到错误

servlet-context.xml：

看起来您正在扫描com.logicalideasJPA

<context:component-scan base-package="com.logicalideasJPA" />

---

虽然您的JPA类预计位于com.logicalideas.persistence，但根据您得到的异常情况。尝试更改扫描包名称。

在您的

entityManagerFactory

bean中，您必须将包设置为扫描，以便休眠以找到您的实体：

<beans:bean id="entityManagerFactory"
         class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    ...
    <beans:property name="packagesToScan" value="com.logicalideas.persistence"/>
    ...
</beans:bean>

...
...

您可以找到更多信息。

您可以发布persistence.xml文件吗？谢谢您的回复，我没有使用persistence.xml文件，我已经将所有配置放在了数据源中。我已经设法摆脱了大多数错误，它运行到索引页很好，但在请求时，它用另一个错误来迎接我<代码>警告：org.springframework.web.servlet.PageNotFound-在名为“appServlet”的DispatcherServlet中找不到URI为[/logicalideasJPA/contacts.html]的HTTP请求的映射

<beans:bean id="entityManagerFactory"
         class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    ...
    <beans:property name="packagesToScan" value="com.logicalideas.persistence"/>
    ...
</beans:bean>
