Recently, when I was working on a project, I met a problem. After a long time of trying many online methods, I failed to find a solution. Finally, I found a solution.

The following is an error report:

Upgrading spring from 3.1 to 3.2 started tomcat with the above error.

Having carefully examined the introduction of spring configuration in web.xml, spring-mvc configuration is not a problem.

And the way spring configuration files are read, including the configuration of listening parameters, is also correct.

The configuration for introducing and monitoring web.xml is as follows:

    <context-param>  
            <param-name>contextConfigLocation</param-name>  
            <param-value>  
                classpath:spring/applicationContext-spring-rmi-client.xml,  
                classpath:spring/spring-context.xml  
            </param-value>  
        </context-param>  
        <listener>  
            <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  
        </listener>  
        <listener>  
            <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>  
        </listener>  

It's no problem to change back to 3.1, but it's no good to change to 3.2. To check the compiler environment, 1.8 is used, and 1.8 is reduced to 1.7. The problem is solved and the service starts normally.

That is to say, spring 3.2 does not support 1.8 compilation environment, the solution is to reduce to 1.7 compilation environment.

The compilation environment configuration is shown as follows:

Spring's official website says that to use java 8, only the versions above spring 4.X are supported, while the minimum java requirement for spring is java 5 and above.

If there are exceptions, then there are exceptions. For example, spring 3.1 can be compiled on Java 8 at the beginning.
