我有一个带有以下 pom.xml 的简单 Spring Boot 项目

我的主要应用是：-

package com.a2i.restweb;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class A2iwebTestApplication {

public static void main(String[] args) {
    SpringApplication.run(A2iwebTestApplication.class, args);
}

}

我遇到了异常

这个错误可以通过更改 spring boot 版本得到修复，但是会产生另一个版本

如果我将版本更改为

a)1.5.10.RELEASE
错误：-在 org.springframework.core.BridgeMethodResolver.findBridgedMethod(BridgeMethodResolver.java:60) nullpointerException

b)2.1.2.发布

错误：- 原因：java.lang.NoSuchMethodError: org.springframework.core.KotlinDetector.isKotlinReflectPresent()Z

c)2.0.5.RELEASE

错误：- 原因：java.lang.NoSuchFieldError: logger

d) 1.5.9.发布

错误：- java.lang.NullPointerException: null 在 org.springframework.core.BridgeMethodResolver.findBridgedMethod(BridgeMethodResolver.java:60)

e)2.0.1.RELEASE

错误：- 原因：java.lang.ClassCastException：org.springframework.boot.autoconfigure.condition.ConditionalOnJava$JavaVersion 无法转换为 org.springframework.boot.system.JavaVersion

【问题讨论】：

做mvn clean install，看看2.0.1会不会报错
@AkshayBatra 我每次在更改 Spring Boot 版本后都尝试过这个。我也尝试从 m2/respository..folder 中删除..我没有工作
您使用的是哪个版本的 Java？
java 1.8 版

标签： spring maven spring-boot spring-mvc pom.xml

【解决方案1】：

project->properties->maven :- 取消选中已解决的依赖复选框。
