一个项目,spring+hibernate,启动tomcat容器时报错:No bean named 'sessionFactory' is defined 

百度了许多,基本归为:

1. spring-hibernate.xml文件路径写错了或没引入

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:/spring-hibernate.xml</param-value>
</context-param>

2.相关jar包没有引用

3.spring-hibernate.xml中,启动顺序错误,正确启动顺序应为:dataSource->sessionfactory->事务相关

4.spring-hibernate.xml中,应用了${},但相关文件没有引入或出错

5.OpenSessionInViewFilter引入导致出错

6.没有加入ContextLoaderListener导致没有自动装配applicationContext配置信息

    <listener>
        <listener-class>
            org.springframework.web.context.ContextLoaderListener
        </listener-class>
    </listener>


我上次犯得是第6个错。

若依微服务:启动类调整@SpringBootApplication(exclude = {DynamicDataSourceAutoConfiguration.class}) 配置文件 # 分库分表配置 shardingsphere: datasource: names: master,slave master: driver-class-name: com.mysql.cj.jdbc.Driver type: com.zaxxer.hikari.HikariDataSource username: root 启动报错 11:34:53.889 [main] ERROR o.s.b.w.e.t.TomcatStarter - [onStartup,61] - Error starting Tomcat context.
