I have a spring boot application that works fine when I run it using the embedded server from Intellj. However, when I package it into .war file and deploy it on tomcat I get the following error:

我有一个 Spring Boot 应用程序，当我使用 Intellj 的嵌入式服务器运行它时，它运行良好。但是，当我将其打包成 .war 文件并将其部署在 tomcat 上时，出现以下错误：

My project does not contain multiple web-fragment so I don't know what could be causing this problem.

我的项目不包含多个网络片段，所以我不知道是什么导致了这个问题。

Sounds like you have two different versions of Spring, check your dependencies to see if you have a dependency to another Spring-version.

听起来您有两个不同版本的 Spring，请检查您的依赖项以查看您是否对另一个 Spring 版本有依赖项。

mvn dependency:tree -Dverbose -Dincludes=groupId:artifactId

This problem was solved by adding absolute ordering of deployment descriptors.

通过添加部署描述符的绝对顺序解决了这个问题。

The tag <absolute-ordering/>was added to the web.xml

标签<absolute-ordering/>被添加到 web.xml

I had the same problem and solved it. Got similar errors but not used spring boot. I have used spring 3.x with java 8. If above solutions are not working change the jars and search whether those jars are compatible with the java version you are using or not. spring 3.x is not compatible with java 8.

我遇到了同样的问题并解决了它。有类似的错误，但没有使用弹簧靴。我在 java 8 中使用了 spring 3.x。如果上述解决方案不起作用，请更改 jars 并搜索这些 jars 是否与您使用的 java 版本兼容。spring 3.x 与 java 8 不兼容。

This error seems to happen after project's spring framework update, clearing the project history file in tomcat webappsmay solve the problem.

这个错误好像是项目的spring框架更新后出现的，在tomcat中清除项目历史文件webapps可能会解决问题。

My project is Springboot based version (1.5.21.RELEASE) and generating war and deploying in physical tomcat. I had gotten the same issue and got resolved with below approach.

我的项目是基于 Springboot 的版本 (1.5.21.RELEASE) 并在物理 tomcat 中生成战争和部署。我遇到了同样的问题，并通过以下方法得到了解决。

Solution: Exclude tomcat-embed-websocket dependency from spring-boot-starter-web in the pom.xml

解决方案：在 pom.xml 中从 spring-boot-starter-web 中排除 tomcat-embed-websocket 依赖

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <version>${spring.boot.version}</version>
            <exclusions>
                **<exclusion>
                    <groupId>org.apache.tomcat.embed</groupId>
                    <artifactId>tomcat-embed-websocket</artifactId>

            </exclusions>
        </dependency>

Answer 10

回答by Anuj Panwar

This error generally comes from that if we have two copy of spring in our container, which get loaded by different class loaders(in my case shared class loader and webapp class loader).

这个错误通常来自如果我们的容器中有两个 spring 副本，它们由不同的类加载器加载（在我的例子中是共享类加载器和 webapp 类加载器）。

Check effective pom, if you have any bundle embed spring jars/classes, if so remove it, you should use the one installed as bundle from container.

检查有效的 pom，如果您有任何包嵌入弹簧罐/类，如果有，请将其删除，您应该使用从容器中作为包安装的那个。
