无法实例化接口 org.springframework.context.ApplicationContextInitializer (Spring 5.2.3 + Spring Boot 2.2.3)答案

【问题标题】：Cannot instantiate interface org.springframework.context.ApplicationContextInitializer (Spring 5.2.3 + Spring Boot 2.2.3)无法实例化接口 org.springframework.context.ApplicationContextInitializer (Spring 5.2.3 + Spring Boot 2.2.3)

【问题描述】：

我正在使用 Spring 5.2.3.RELEASE 和 Spring Boot 2.2.3.RELEASE。

在尝试为我的应用程序运行一些集成测试时，我收到以下错误：

 Exception in thread "main" java.lang.reflect.InvocationTargetException
    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

    at org.springframework.beans.BeanUtils.instantiateClass(BeanUtils.java:187)
    at org.springframework.boot.SpringApplication.createSpringFactoriesInstances(SpringApplication.java:441)

我认为此错误与某些组件的不兼容版本有关。

这个类似的问题https://github.com/spring-projects/spring-boot/issues/15970 说：

isKotlinReflectPresent 在 5.1 中被添加到 Spring Framework。因此，我怀疑您有一些来自 Framework 5.0 的 jar （或更早）在类路径中。

但我无法确定是哪个依赖项导致了问题？

这是我的 pom.xml：

【问题讨论】：

请贴出 mvn dependency:tree 的结果
感谢@satyesht，将mvn dependency:tree 的输出添加到我的问题中

标签： java spring spring-boot maven

【解决方案1】：

您已经删除了您的 pom，但我怀疑这是由于您明确定义了 Spring Boot 管理的依赖项的版本。

你的 pom 应该有 Spring Boot 作为它的父级：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.2.4.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
  </parent>
  <groupId>com.example</groupId>
  <artifactId>demo</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <name>demo</name>
  <description>Demo project for Spring Boot</description>
  <properties>
    <java.version>1.8</java.version>
  </properties>
  <dependencies>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-web</artifactId> <!-- No version defined -->
    </dependency>
...

我建议通过以下方式修饰你的 pom：

删除 Spring Boot 管理的依赖项版本。
删除已由 Spring Boot 启动器传递引入的依赖项。

【讨论】：

谢谢，如果你想看一下，我现在已经把我的 pom.xml 添加回来了 :-)

【解决方案2】：

上面mvn dependency:tree中显示的这个依赖引入了旧版本的Spring，导致运行时错误：

[INFO] +- com.github.acmecorpapi:swagger-ui-annotation:jar:1.0.0-SNAPSHOT:compile
[INFO] |  +- org.springframework:spring-core:jar:5.0.8.RELEASE:compile

解决此问题的方法是：

更新上述依赖以使用 Spring 5.2.3
在我的项目中使用 Spring 5.0.8
