SSH配置中出现问题

Posted 2020-08-22 小企鹅ITgo

问题1：org.springframework.beans.factory.NoSuchBeanDefinitionException:

org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named \'sessionFactory\' is defined

1）在web.xml中添加：

<!-- 解决Hibernate延迟加载问题 -->
  <filter>  
       <filter-name>HibernateOpenSession</filter-name>    
      <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>  
      <init-param>  
        <param-name>sessionFactoryBeanName</param-name>  
       <param-value>mySessionFactory</param-value>
     </init-param>
</filter>  

　2）在基础类中重写sessionFactory方法

// 使用注解方式进行依赖注入
        @Resource
        // @Autowired
        // @Qualifier(value="abc")
        public void setMySessionFactory(SessionFactory sessionFactory) {
            super.setSessionFactory(sessionFactory);
        }

问题2： javax.servlet.ServletException: Servlet.init() for servlet springMVC threw exception

org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:504)
 3     org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:103)

17 java.lang.IllegalArgumentException

21     org.springframework.core.type.classreading.SimpleMetadataReader.<init>(SimpleMetadataReader.java:52)

解决办法：

一：把jdk版本换成1.7 or 1.7以下

1）打开eclipse后依次打开windows——》Preferences，打开属性窗口

2）在打开的preferences窗口的左边树形菜单中依次展开：java——》Compiler，如图

然后点击apply

原因：1.8版本与asm.jar不兼容

二：使用spring 4.0RELEASE及以上版本

 问题3：applicationContext.xml

解决方法：

1）applicationContext.xml文件的位置放置

 

 

2）在web.xml中配置

<!-- 指定spring配置文件的位置 -->
  <context-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath*:config/applicationContext.xml</param-value>
  </context-param>
  <listener>
      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
