我的主要应用程序是:-
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);
}
}
我正在获得

通过更改spring boot版本可以解决此错误,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。发布
错误:-由以下原因引起:java.lang.NoSuchMethodError:org.springframework.core.KotlinDetector.isKotlinReflectPresent()Z
c)2.0.5。发布
错误:-由以下原因引起:java.lang.NoSuchFieldError:记录器
d)1.5.9。发布
错误:-java.lang.NullPointerException:空 在org.springframework.core.BridgeMethodResolver.findBridgedMethod(BridgeMethodResolver.java:60)
e)2.0.1.RELEASE
错误:-由以下原因引起:java.lang.ClassCastException:org.springframework.boot.autoconfigure.condition.ConditionalOnJava $ JavaVersion无法转换为org.springframework.boot.system.JavaVersion
