添加外部Jar无效，出现NoClassDefFoundError

编程问答 2022-08-11

问题描述

我创建了一个AOP Library项目，该项目具有“ Before＆After”方面注释，我给出了Maven Build，并且成功。我需要在其他服务项目中使用的相同库或注释。我已将库项目Jar添加为构建路径中的外部库。 我可以在“参考库”文件夹中看到Jar文件。 当我运行Service项目时，我收到了NoClassDefFoundError。

import org.springframework.context.annotation.ComponentScan;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import com.**.****.****.aspect.GenesisApiAudit;
import com.**.****.****.aspect.GenesisApiAuditLight;

@RestController
@ComponentScan("com.**.****.****.aspect") //aspect implementation class path
 public class TestAuditController {
    @GetMapping("/hello")
    @GenesisApiAudit
    @GenesisApiAuditLight   
    public String testHello(@RequestParam(defaultValue = "test") String id) {
    
        return "Hello world : ";
    }
}

请参阅下面的Maven Build日志>>>
