Spring Boot Maven -如何添加spring-模拟破坏这个项目？

Question

免责声明:我不是JVM专家，所以我对Maven或Spring没有太多经验。如果有明显的错误，我很抱歉。

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

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>

...I得到了以下错误：

***************************
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spring的原始pom.xml -模拟添加

Answer 1

您可以使用mvn dependency:tree查看项目的所有依赖项。在项目中添加了对spring-mock的依赖后，该树的一部分如下所示：

[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

这表明org.springframework:spring-mock:jar:2.0.8依赖于commons-logging:commons-logging:jar:1.1，而后者依赖于javax.servlet:servlet-api:jar:2.3。您可以通过排除Servlet来避免这个问题：

<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，我建议退一步，询问为什么要将spring-mock添加到项目中。它于2008年发布，多年来一直得不到支持。它是SpringFramework2.0.8的一部分，使用的Spring版本2.3.0.RELEASE需要SpringFramework5.2.x。
