我在我的 mvc-config.xml 中添加了以下内容：

<mvc:annotation-driven />

<context:property-placeholder location="classpath:database.properties" />

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

<jpa:repositories base-package="com.spr.repository" entity-manager-factory-ref="myEmf" />

<tx:annotation-driven transaction-manager="transactionManager"/>

<bean id="shopService" class="com.spr.service.ShopServiceImpl" />
<bean id="shopValidator" class="com.spr.service.ShopServiceImpl" />

【解决方案1】：

您需要进行以下更改。阿里的建议也不错。

您需要在 src/main/java 文件夹中创建META-INF\persistence.xml 文件。

persistence.xml

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
    <persistence-unit name="spring-data-jpa-krishna" transaction-type="RESOURCE_LOCAL">
        <class>com.spr.model.Shop</class>
    </persistence-unit>
</persistence>

这些很重要。确保您的配置中没有遗漏任何内容：

<mvc:annotation-driven />

    <context:property-placeholder location="classpath:database.properties" />

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

    <jpa:repositories base-package="com.spr.repository" />

    <tx:annotation-driven transaction-manager="transactionManager"/>

    <!-- Necessary to get the entity manager injected into the factory bean -->
    <bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" />

下一个重要的，不要使用id=myEmf，下面简单使用：

<bean id="jpaVendorAdapter" class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
        <property name="showSql" value="true"/>
        <property name="generateDdl" value="true"/>
        <!-- <property name="database" value="MYSQL"/> -->
    </bean>

只需使用这个：

<!-- Local Container Entity Manager -->
    <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="dataSource" ref="dataSource" />

        <property name="packagesToScan" value="com.spr.model" />

        <property name="jpaVendorAdapter" ref="jpaVendorAdapter"/>

        <property name="jpaProperties">
            <props>
                <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>
                <prop key="hibernate.dialect">${hibernate.dialect}</prop>
            </props>
        </property>
    </bean>

【讨论】：

【解决方案2】：

将组件扫描器添加到您的mvc-config.xml。这样你告诉 Spring 扫描你的控制器包并实例化和注册你的 Handler Methods。假设，您的控制器在 com.so.controller 包中，那么您应该将其添加到 mvc-config.xml：

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

此外，您确实在 mvc-config.xml 中启用了两次注释驱动的 MVC：

<mvc:annotation-driven />

<!-- Enables the Spring MVC @Controller programming model -->
<mvc:annotation-driven />

只保留一个并删除另一个。最后一点，最好为应用程序的每个架构方面定义多个 配置文件，例如Web、数据访问、安全等，并且只将相关的大火放在其中。目前，您有一个 mvc-config.xml 配置文件，其中包含您的数据访问相关配置。

【讨论】：

您的服务也有同样的问题。当您使用诸如Service、Controller、Repository 等原型注释来注释某些类时，您还应该使用组件扫描器告诉 spring 这些类在哪里。
现在，使用您的顶级包作为base-package 的值。
<bean id="shopValidator" class="com.spr.service.ShopServiceImpl" />: ShopServiceImpl 不是ShopValidator 的实现。不是吗？
因为您没有定义ShopValidator bean。您刚刚将ShopService 与<bean id="shopValidator" class="com.spr.service.ShopServiceImpl" /> 复制了。将其更改为 <bean id="shopValidator" class="com.spr.service.ShopValidatorImpl" />
哦。道歉。我无法意识到这一点。我不知道为什么它现在说这个错误：java.lang.IllegalStateException: No persistence units parsed from {classpath*:META-INF/persistence.xml}
