問題描述

我正在嘗試為我的Web應用程序設置LightAdmin頁面，正在關注https://github.com/la-team/light-admin 。 執行完此步驟后，看到此錯誤： 

 14:36:55.705 [localhost-startStop-1] DEBUG o.s.b.f.s.DefaultListableBeanFactory - Destroying singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@77bc4d5: defining beans [dataSource,userJDBCTemplate,teamJDBCTemplate,entityManagerFactory,transactionManager]; root of factory hierarchy
 14:36:55.708 [localhost-startStop-1] ERROR o.s.web.context.ContextLoader - Context initialization failed

 ....
 Caused by: java.lang.IllegalStateException: No persistence units parsed from {classpath*:META-INF/persistence.xml}

這是我的web.xml文件：

你可以幫幫我嗎？ 我正在嘗試使用管理頁面來創建/更新/刪除/顯示用戶和團隊。 還是有更好的方法呢？

2 個解決方案

該消息是指缺少persistence.xml文件。 該文件通常包含您為Hibernate / JPA定義的實體的引用。

根據您提交的文件，我無法完全重現您的問題，您是否有辦法在GitHub上共享您的項目？ 您能否提供一些有關如何部署它的額外見解？

我快速瀏覽了您的項目。 我看不到您在哪里使用jpa，似乎您正在使用jdbctemplate進行數據訪問。

您為什么不從配置中刪除這些行，看看是否能使您走得更遠。 

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

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

如果您配置了與jpa相關的bean，那么您將告訴Spring-Boot不要自動配置，然后負責替換框架為您完成的“魔術”。

Spring Boot應該提供合理的默認配置。 如果以后開始使用JPA（實體，存儲庫等）來訪問數據，則可以添加特定的配置。

您可以在HomeController中嘗試以下操作： 

@Autowired
private UserJDBCTemplate userJDBCTemplate;

@Autowired
private TeamJDBCTemplate teamJDBCTemplate;

代替這個： 

ApplicationContext context =  new ClassPathXmlApplicationContext("root-context.xml");

    UserJDBCTemplate ubd =(UserJDBCTemplate)context.getBean("userJDBCTemplate");
    TeamJDBCTemplate tbd =(TeamJDBCTemplate)context.getBean("teamJDBCTemplate");
