找不到SpringApplicationConfiguration:错误的spring-boot-starter-test内容?

问题描述

在Maven中遇到编译错误:

Getting a compilation error in Maven:

[INFO] -------------------------------------------------------------
[ERROR] COMPILATION ERROR :
[INFO] -------------------------------------------------------------
[ERROR] /C:/prototypes/demo-sse-spring-boot-master/src/test/java/com/cedric/demo/sse/SseDemoApplicationTests.java:[6,37] package org.springframework.boot.test does not exist
[ERROR] /C:/TITAN/demo-sse-spring-boot-master/src/test/java/com/cedric/demo/sse/SseDemoApplicationTests.java:[10,2] cannot find symbol
  symbol: class SpringApplicationConfiguration
[INFO] 2 errors
[INFO] -------------------------------------------------------------
[INFO] ------------------------------------------------------------------------
[INFO] BUILD FAILURE
[INFO] ------------------------------------------------------------------------

Maven回购中似乎有jar:

Maven repo seems to have the jar present:

但是，该jar中没有任何已编译的类.仅META-INF目录:

howerever that jar doesn't have any compiled classes inside it. only META-INF dir:

这是设计使然吗?在哪里可以找到包含 SpringApplicationConfiguration 类的jar，以使Maven开心?

Is that by design? Where do I get the jar containing SpringApplicationConfiguration class to make Maven happy?

这是我pom.xml的相关部分:

Here's the relevant parts of my pom.xml:

像所有其他Spring Boot入门者一样，

推荐答案

spring-boot-starter-test实际上只是一个pom，它可传递地引入许多其他依赖项.它只有一个jar，可以使一些不喜欢仅含pom的依赖关系的构建系统满意.

spring-boot-starter-test, like all the other Spring Boot starters, is really just a pom that pulls in a number of other dependencies transitively. It only has a jar to keep some build systems that don't like pom-only dependencies happy.

似乎您已将应用程序从Spring Boot 1.4升级到Spring Boot 1.5. Spring Boot 1.5删除了1.4中不推荐使用的许多类，包括org.springframework.boot.test.SpringApplicationConfiguration.

It looks like you have upgraded an application from Spring Boot 1.4 to Spring Boot 1.5. Spring Boot 1.5 removes a number of classes that were deprecated in 1.4, including org.springframework.boot.test.SpringApplicationConfiguration.

我建议回到Spring Boot 1.4.4.RELEASE并修复所有弃用警告.然后，您应该可以轻松升级到Spring Boot 1.5.1.RELEASE.

I would recommend dropping back to Spring Boot 1.4.4.RELEASE and fixing all of the deprecation warnings. You should then be able to upgrade to Spring Boot 1.5.1.RELEASE without difficulty.
