Spring-没有EntityManager可以用于当前线程的实际事务处理-无法可靠地处理“持久”调用
当尝试调用“ persist”方法将实体模型保存到Spring MVC Web应用程序中的数据库时，出现此错误。在Internet上找不到与该特定错误相关的任何帖子或页面。似乎似乎EntityManagerFactory bean出了点问题，但是我对Spring编程还是比较陌生，所以对我来说，似乎一切都已初始化好，并且根据Web上的各种教程文章。 dispatcher-servlet.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:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xmlns:jpa="http://www.springframework.org/schema/data/jpa" xsi:schemaLocation=" http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.2.xsd http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa-1.3.xsd http://www.springframework.org/schema/data/repository http://www.springframework.org/schema/data/repository/spring-repository-1.5.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.2.xsd"> <context:component-scan base-package="wymysl.Controllers" /> <jpa:repositories base-package="wymysl.repositories"/> <context:component-scan base-package="wymysl.beans" /> <context:component-scan base-package="wymysl.Validators" /> <bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" /> <bean class="org.springframework.orm.hibernate4.HibernateExceptionTranslator"/> <bean id="passwordValidator" class="wymysl.Validators.PasswordValidator"></bean> <bean …
