java.lang.NoClassDefFoundError:org / springframework / web / client / ResponseErrorHandler

标签: java spring maven heroku httpwebresponse

当我尝试在 HEROKU 中打开已部署的应用程序时出现此问题。 Spring Framework类ResponseErrorHandler正在抛出NoClassDefFoundError。我尝试更改xml和属性文件,但是徒劳无功。

我可以提供一些建议,以便我可以更改代码/其他文件,以便我可以打开我的应用程序。 提前谢谢!

好吧,我看到我还没有回答这个问题。所以尽管已经很晚了,但我会提供解决这个问题的方法。

除了Jens提出的更改之外,我在pom.xml的插件标记中添加了以下插件。

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
</plugin>

我意外地从pom.xml删除了这个导致上述问题的插件。

答案 1 :(得分:2)

您错过了类路径中的org.springframework.web。将它添加到你的pom中它应该可以工作。

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-web</artifactId>
    <version><!--your spring version--></version>
</dependency>

答案 2 :(得分:0)

就我而言,这仅适用于(适用于可执行jar文件):

插件:

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <version>2.1.6.RELEASE</version>
    <executions>
        <execution>
            <goals>
                <goal>repackage</goal>
            </goals>
        </execution>
    </executions>
</plugin>

依赖性(与Jens答案相同)

<dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-web</artifactId>
        <version>5.0.10.RELEASE</version>
</dependency>

答案 3 :(得分:0)

尽管回答得很晚,但让我加2美分,对我来说,所有jar和build插件都在pom中,但是jar的作用域是“提供的”,因此尽管它在jar中运行,但并未通过我的IDE(intelliJ)曾经评论说一切正常。
