Spring无法解析bean

Spring 4和Tomcat。

我试图将一个非常简单的spring-bootstrap项目迁移到没有spring boot的传统spring webApp。 问题是我无法获得依赖注入工作，因为我不知道春天在哪里/如何查找bean。

您可以在以下网址找到我的源代码：

https://github.com/aleponchu/SpringTomcatJsp

当我在tomcat中部署项目时，我得到了这个堆栈跟踪：

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [monkey.woodstock.repositories.ProductRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {}

    at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredMethodElement.inject(AutowiredAnnotationBeanPostProcessor.java:553)

这是完整的堆栈跟踪：

提前感谢所有人。

2 个答案:

答案 0 :(得分：1)

  1. 删除@Repository和ParteRepository上的ProductRepository注释。

  2. 在<jpa:repositories base-package="monkey.woodstock.repositories" />中添加mvc-dispatcher-servlet.xml，以便将ParteRepository和ProductRepository注册为JpaRepository bean。

  3. 您需要配置EntityManagerFactoryBean，TransationManager，JPA属性以及JPAVendor（ex-Hibernate）。请参阅此tutorial，了解如何使用Java配置和XML配置对其进行配置。

    4. 请参阅this独立示例。

    阅读此Spring Data JPA Documentation

答案 1 :(得分：0)

您应该配置Spring JPA。具有Hibernate和内存H2数据库的示例JPA配置如下所示：

的persistence.xml 

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jpa="http://www.springframework.org/schema/data/jpa"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/data/jpa
    http://www.springframework.org/schema/data/jpa/spring-jpa.xsd">

    <jpa:repositories base-package="monkey.woodstock.repositories" />

    <bean id="dataSource"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="org.h2.Driver" />
        <property name="url" value="jdbc:h2:mem:testdb" />
        <property name="username" value="sa" />
        <property name="password" value="" />
    </bean>

    <bean id="jpaVendorAdapter"
        class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
        <property name="showSql" value="true" />
        <property name="generateDdl" value="true" />
        <property name="database" value="H2" />
    </bean>

    <bean id="entityManagerFactory"
        class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="jpaVendorAdapter" ref="jpaVendorAdapter" />
        <!-- spring based scanning for entity classes -->
        <property name="packagesToScan" value="monkey.woodstock.domain" />
        <property name="persistenceUnitName" value="DefaultPersistenceUnit" />
    </bean>  
</beans>

在pom.xml文件中添加h2 db依赖项，并在mvc-dispatcher-servlet.xml（<import resource="persistence.xml" />）

中导入此xml配置
