java - 由 org.springframework.beans.factory.BeanCreationException 引起的成功安装 maven 的 Tomcat war 部署错误

Question

我正在尝试在 tomcat 中部署一个 war 文件，但在部署时出现以下错误。我用maven安装，没有看到任何错误。当我部署 tomcat 时，我在日志中看到以下错误。我没有 application.xml 设置。

感谢任何帮助!!!

下面是我的 pom.xml 片段。在 maven 安装期间也进行了测试，但没有通过任何错误。

Answer 1

这可能是依赖性问题。这里有几个使用它的步骤，您可以解决它们。

1) 将以下插件添加到您的 pom 构建标签中。

          <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-enforcer-plugin</artifactId>
            <version>1.4.1</version>
            <configuration>
                <rules>
                    <dependencyConvergence />
                </rules>
            </configuration>
        </plugin>

然后运行mvn enforcer:enforce

这将为您提供所有冲突依赖项及其组 ID 和 Artifact ID 的列表，您只需要从相关依赖项中排除即可。

这是非常有用的方法。

2) 第二种方式。

从 pom 目录运行 mvn dependency:tree 命令。

这将在树结构中列出所有依赖项及其子依赖项，您必须查看树列表并找到重复项，然后将它们从相对依赖项中排除。

我建议您尝试第一步，这很容易解决。

希望对您有所帮助。
