我的数据库详细信息是正确但我不知道为什么我收到此错误： -

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'accountDaoBean' defined in file [E:\new project\marsWorkspase\SpringProgram\bin\beans.xml]: Cannot resolve reference to bean 'hibernateTemplateBean' while setting bean property 'hibernateTemplate'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'hibernateTemplateBean' defined in file [E:\new project\marsWorkspase\SpringProgram\bin\beans.xml]: Cannot resolve reference to bean 'sfBean' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sfBean' defined in file [E:\new project\marsWorkspase\SpringProgram\bin\beans.xml]: Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: javax/transaction/TransactionManager

您需要解决的问题：

1 - 将JAR（javaee-api）放入LIB文件夹

http://mvnrepository.com/artifact/javax/javaee-api/7.0

2 - 如果您使用的是Maven，请添加以下依赖项

<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-api</artifactId>
    <version>6.0</version>
</dependency>

3 - 配置您的工件并包含此jar，允许部署

4 - 将javaee-api jar放入tomcat / jboss lib文件夹
