spring - Spring Boot Maven - 添加 spring-mock 如何破坏这个项目？

问题描述

免责声明：我不是 JVM 专家，所以我对 Maven 或 Spring 没有太多经验。如果有任何明显的错误，我深表歉意。

我继承了一个 Java+Kotlin 项目，并pom.xml在这个问题的末尾配置了一个。

我遇到的问题是当我添加对 spring-mock 的引用时：

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-mock</artifactId>
            <version>2.0.8</version>
        </dependency>

...我收到此错误：

***************************
APPLICATION FAILED TO START
***************************

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    org.apache.catalina.authenticator.AuthenticatorBase.startInternal(AuthenticatorBase.java:1321)

The following method did not exist:

    javax.servlet.ServletContext.getVirtualServerName()Ljava/lang/String;

The method's class, javax.servlet.ServletContext, is available from the following locations:

    jar:file:/home/atrauzzi/.m2/repository/javax/servlet/servlet-api/2.3/servlet-api-2.3.jar!/javax/servlet/ServletContext.class
    jar:file:/home/atrauzzi/.m2/repository/org/apache/tomcat/embed/tomcat-embed-core/9.0.35/tomcat-embed-core-9.0.35.jar!/javax/servlet/ServletContext.class

It was loaded from the following location:

    file:/home/atrauzzi/.m2/repository/javax/servlet/servlet-api/2.3/servlet-api-2.3.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of javax.servlet.ServletContext

没有添加 spring-mock 的原始 pom.xml

解决方案

您可以使用mvn dependency:tree查看项目的所有依赖项。将依赖spring-mock项添加到您的项目后，该树的一部分如下：

[INFO] com.myproject:pdf-things:jar:0.0.1-development
[INFO] +- org.springframework:spring-mock:jar:2.0.8:compile
[INFO] |  +- commons-logging:commons-logging:jar:1.1:compile
[INFO] |  |  +- log4j:log4j:jar:1.2.12:compile
[INFO] |  |  +- logkit:logkit:jar:1.0.1:compile
[INFO] |  |  +- avalon-framework:avalon-framework:jar:4.1.3:compile
[INFO] |  |  \- javax.servlet:servlet-api:jar:2.3:compile

它表明这org.springframework:spring-mock:jar:2.0.8取决于commons-logging:commons-logging:jar:1.1哪个取决于javax.servlet:servlet-api:jar:2.3. 您可以通过排除 Servlet API 来避免该问题：

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-mock</artifactId>
    <version>2.0.8</version>
    <exclusions>
        <exclusion>
            <groupId>javax.servlet</groupId>
            <artifactId>servlet-api</artifactId>
        </exclusion>
    </exclusions>
</dependency>

但是，与其这样做，我建议您退后一步，质疑您为什么要添加spring-mock到您的项目中。它于 2008 年发布，多年来一直不受支持。它是 Spring Framework 2.0.8 的一部分，您使用的 Spring Boot 版本 2.3.0.RELEASE 需要 Spring Framework 5.2.x。
