proxyBeanMthods annotation error when running springboot application

问题

I am trying to run my first springboot application but facing some issues.

In my application file, this is my code

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);
    }

}

but when i run my application, i get the following error. confused as to why i should get this error and how to solve it.

org.springframework.core.annotation.AnnotationConfigurationException: Attribute 'proxyBeanMethods' in annotation [org.springframework.boot.autoconfigure.SpringBootApplication] is declared as an @AliasFor nonexistent attribute 'proxyBeanMethods' in annotation [org.springframework.context.annotation.Configuration].; nested exception is java.lang.NoSuchMethodException: org.springframework.context.annotation.Configuration.proxyBeanMethods()

This is my pom.xml file

Does anyone have an idea of how to fix this issue?

Thanks

回答1:

from spring-projects-github

" proxyBeanMethods is new in 5.2 and I can see 5.1.2.RELEASE in some elements of the stack."

do a dependency:tree and double check that spring match >= 5.2, I had a similar issue and one library brought 5.1 overriding v5.2 from springboot

Had same problem few days ago. Try to change spring-boot-starter-parent version to 2.1.3.RELEASE, thats resolved my problem.

回答3:

I had this error happen in a Spring Boot project where I added a custom dependency that made use of Spring (not Spring Boot). The issue in my custom dependency was that it had the following plugin configuration:

<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>

Once I removed the shade plugin from my custom dependency, the error disappeared.
