I have no custom code, I used IntelliJ and Spring. Can you help me?

回答1:

Your jar dependencies are missing. You have to import them manually or in case of using Maven, add thee lines to your pom.xml, that assures all the dependencies.

<properties>
    <spring.version>4.3.2.RELEASE</spring.version>
</properties>

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-core</artifactId>
    <version>${spring.version}</version>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-web</artifactId>
    <version>${spring.version}</version>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-webmvc</artifactId>
    <version>${spring.version}</version>
</dependency>

Then you can clean and rebuild your project. It should be ok.

In same cases this is due to a conflict within WebLogic internal libraries and your application, may be you should try to use this :

<prefer-application-packages>    
   <package-name>org.springframework.*</package-name>
</prefer-application-packages>
