Spring MVC Hibernate Integration- PageNotFound - 未找到具有 URI [/spring-mvc-hibernate-xml/shop/create] 的 HTTP 请求的映射
Spring MVC Hibernate Integration- PageNotFound - No mapping found for HTTP request with URI [/spring-mvc-hibernate-xml/shop/create]
我正在开发 Spring MVC + Hibernate + JPA 集成 示例。我成功地开发了这个示例并能够启动 index.jsp，但是当我尝试调用另一个 jsp 时，我看到以下错误即将到来..

我在我的 mvc 中添加了以下内容-config.xml:
<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" />
将 组件扫描器 添加到您的 mvc-config.xml。通过这种方式，您可以告诉 Spring 扫描您的控制器包并实例化并注册您的 处理程序方法 。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:
中两次启用了注解驱动的 MVC
<mvc:annotation-driven />
<!-- Enables the Spring MVC @Controller programming model -->
<mvc:annotation-driven />
只保留一个，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，并且只在它们中的每一个中放置相关的大火。目前，您有一个 mvc-config.xml 配置文件，其中包含与数据访问相关的配置。
您需要进行以下更改。还有阿里的建议很好很正确
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" />
接下来重要的，不要用id=myEmf，下面简单用一下：
<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>
我正在开发 Spring MVC + Hibernate + JPA 集成 示例。我成功地开发了这个示例并能够启动 index.jsp，但是当我尝试调用另一个 jsp 时，我看到以下错误即将到来..

Caused by: org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.spr.validation.ShopValidator com.spr.controller.ShopController.shopValidator; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.spr.validation.ShopValidator] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

我在我的 mvc 中添加了以下内容-config.xml:
<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" />
将 组件扫描器 添加到您的 mvc-config.xml。通过这种方式，您可以告诉 Spring 扫描您的控制器包并实例化并注册您的 处理程序方法 。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:
<mvc:annotation-driven />
<!-- Enables the Spring MVC @Controller programming model -->
<mvc:annotation-driven />
只保留一个，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，并且只在它们中的每一个中放置相关的大火。目前，您有一个 mvc-config.xml 配置文件，其中包含与数据访问相关的配置。
您需要进行以下更改。还有阿里的建议很好很正确
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" />
接下来重要的，不要用id=myEmf，下面简单用一下：
<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>
