spring - 无法决定我应该使用哪个 Spring Boot 版本？

问题描述

我有一个带有以下 pom.xml 的简单 Spring Boot 项目

<?xml version="1.0" encoding="UTF-8"?>

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);
}

}

我得到了例外

通过更改 spring boot 版本可以修复此错误，但会导致另一个版本为

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.释放

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

c)2.0.5.RELEASE

错误： - 引起：java.lang.NoSuchFieldError：记录器

d) 1.5.9.发布

错误：- java.lang.NullPointerException：在 org.springframework.core.BridgeMethodResolver.findBridgedMethod 处为空（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
