Spring + JPA + Postgresql配置

從頭創建一個簡單的Spring MVC。我的配置是Spring + JPA + Postgresql。我希望使用XML完成配置，並且我無法使用JPA設置數據庫連接配置。我想從頭開始配置它，並想知道它的每一個部分。Spring + JPA + Postgresql配置

我也知道，有配置中的問題，但我不能將它整理出來。我更新的數據-context.xml文件

servlet的context.xml中

<resources mapping="/resources/**" location="/resources/" /> 

<!-- Resolves views selected for rendering by @Controllers to .jsp resources 
    in the /WEB-INF/views directory --> 
<beans:bean 
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">

    <beans:property name="suffix" value=".jsp" /> 
</beans:bean> 

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

根的context.xml

<?xml version="1.0" encoding="UTF-8"?>

<beans:import resource="classpath*:spring/data-context.xml" />

<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"

更新數據的context.xml，添加根context.xml中，servlet的context.xml中，web.xml中 – Isank

您已經配置

<jpa:repositories base-package="com.spring.mvc.domain" transaction-manager-ref="transactionManager" />

當倉庫是不是

com.spring.mvc.repository下的初始問題。

所以你需要<jpa:repositories base-package="com.spring.mvc.repository"/>

注意<jpa:repositories>用於配置Spring JPA的數據存儲庫，爲此你需要指定包含庫的包，包含實體不包。

另請注意，由於您只使用一個事務管理器，因此您可以刪除部分transaction-manager-ref="transactionManager"，因此Spring Data JPA將默認使用該事務。查看this部分文檔。

你可能也想的entityManagerFactory的配置更改爲

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> 
     <property name="dataSource" ref="dataSource" /> 

     <property name="packagesToScan" > 
      <list> 
       <value>com.spring.mvc.domain</value> 
      </list> 
     </property> 

     <property name="jpaProperties"> 
      <props> 
       <!-- whatever you need here --> 
      </props> 
     </property> 
    </bean>

看看this博客文章的完整指南與JPA配置Spring。

最後一點說明，我知道你說過你想明確地配置一切，以便學習Spring的細節，但我會敦促你看看Spring Boot。它將消除由於需要配置Spring而導致的大部分痛苦。

感謝您的回覆但錯誤仍然相同。你能告訴我如何正確配置它。 – Isank

查看我的更新回答 – geoand

你能否給我一個關於配置部分的好教程。 – Isank

變化從

<jpa:repositories base-package="com.spring.mvc.domain" transaction-manager-ref="transactionManager">

基本包到

<jpa:repositories base-package="com.spring.mvc.repository" transaction-manager-ref="transactionManager">
