我的主要申请是:-

代码语言：javascript
复制
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);
}

}

我得到的例外是

此错误通过更改spring引导版本得到修正，但会引发另一个版本，如

如果我将版本更改为

(A)1.5.10.

错误:- at org.springframework.core.BridgeMethodResolver.findBridgedMethod(BridgeMethodResolver.java:60) nullpointerException

(B)2.1.2.

错误：-由: java.lang.NoSuchMethodError: java.lang.NoSuchMethodError引起

(C)2.0.5

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

( d) 1.5.9

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

(E)2.0.1

错误:-由: java.lang.ClassCastException: java.lang.ClassCastException引起，无法将其转换为org.springframework.boot.system.JavaVersion
