Question

我正在尝试运行我的第一个springboot应用程序，但遇到了一些问题。

在我的应用程序文件中，这是我的代码

package com.clog.ServiceMgmt;

import java.util.List;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

@SpringBootApplication
@EntityScan("models")
@ComponentScan({"com.clog.ServiceMgmt","controllers", "models", "repositories"})
@EnableJpaRepositories(basePackages={"repositories"})
public class ServiceMgmtApplication {

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

}

但是当我运行我的应用程序时，出现以下错误。为什么我应该得到这个错误以及如何解决这个问题感到困惑。

org.springframework.core.annotation.AnnotationConfigurationException：批注中的属性“ proxyBeanMethods” [org.springframework.boot.autoconfigure.SpringBootApplication]是在以下位置声明为@AliasFor不存在的属性'proxyBeanMethods' 注释[org.springframework.context.annotation.Configuration]。嵌套异常是java.lang.NoSuchMethodException： org.springframework.context.annotation.Configuration.proxyBeanMethods（）

这是我的pom.xml文件

有人知道如何解决此问题吗？

谢谢

Answer 1

几天前出现了同样的问题。尝试将spring-boot-starter-parent版本更改为2.1.3.RELEASE，这解决了我的问题。

Answer 2

我在Spring Boot项目中发生了此错误，我在其中添加了一个使用Spring的自定义依赖项（不是Spring Boot）。我的自定义依赖项中的问题在于它具有以下插件配置：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <version>2.4.3</version>
    <executions>
        <execution>
            <phase>package</phase>

            <goals>
                <goal>shade</goal>
            </goals>

            <configuration>
                <transformers>
                    <transformer
implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                        <mainClass>com.example.Main</mainClass>
                        <manifestEntries>
                            <Implementation-Title>${project.name}</Implementation-Title>
                            <Implementation-Version>${project.version}</Implementation-Version>
                            <Implementation-Vendor>Vendor Name, ${timestamp}</Implementation-Vendor>
                        </manifestEntries>
                    </transformer>
                </transformers>

                <createDependencyReducedPom>false</createDependencyReducedPom>
            </configuration>
        </execution>
    </executions>
</plugin>

一旦我从自定义依赖项中删除了阴影插件，错误就消失了。

Answer 3

来自spring-projects-github

“ proxyBeanMethods是5.2中的新增功能，在堆栈的某些元素中可以看到5.1.2.RELEASE。”

执行一个依赖项：树并再次检查spring匹配是否大于5.2，我遇到了类似的问题，一个库从springboot中引入了5.1覆盖v5.2。

Answer 4

我删除了以下依赖项

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot</artifactId>
            <version>2.2.1.RELEASE</version>
</dependency>

代码就像魔术一样

Answer 5

在您的主要 spring-boot 应用程序类中使用它：

:@SpringBootApplication(proxyBeanMethods = false)

运行springboot应用程序时，proxyBeanMthods注释错误
