我正在尝试将PostgreSQL数据库与Spring MVC项目集成。在tomcat上执行项目时，我遇到了以下异常和信息：

1 个答案:

答案 0 :(得分：0)

这是因为你有mvc作为你的根命名空间（print( e1.checkLife() ) # 3 lives left... This is printed from within the function # None checkLife() returns None, and you print it here ）而不是你在xmlns="http://www.springframework.org/schema/mvc"命名空间中声明的bean。

尝试使用以下内容替换mvc-dispatcher-servlet.xml的顶部，以将bean声明为根命名空间。

beans

或者，您可以限定bean命名空间中项目的所有引用。因此<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:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation= "http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-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/tx http://www.springframework.org/schema/context/spring-tx-4.0.xsd"> 变为<beans>而<beans:beans>变为<bean>等。
