java - 错误无法检测 ServletContainerInitializers Tomcat 8

Question

我想将我的 springboot 应用程序(war)部署到 apache tomcat 8，我已经在我的类中扩展了 SpringBootServletInitializer，并在我的 pom.xml 中添加了 tomcat，但是在我部署我的 war 之前，日志显示这样的错误

这是我使用 springBootServletInitializer 的主类:

package com.fleet;

import javax.sql.DataSource;

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.springframework.boot.ApplicationArguments;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
//import org.springframework.boot.autoconfigure.jdbc.DataSourceBuilder;
import org.springframework.boot.jdbc.DataSourceBuilder;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.stereotype.Controller;


@SpringBootApplication
@ComponentScan({"com.fleet"})
@ServletComponentScan
@Controller
public class App extends SpringBootServletInitializer {
    
    

    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }
    
    
    
    @Bean(value = "datasource")
    @ConfigurationProperties("app.datasource")
    public DataSource dataSource() {
        return DataSourceBuilder.create().build();
    }
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(App.class);
    }
    

}

为什么会出现此错误，我的代码中是否缺少某些内容？

Answer 1

java.nio.file.AccessDeniedException:

根据上述异常，很明显这是权限问题。只需授予父文件夹权限即可。

要做到这一点，请参阅 How to grant permission to users for a directory using command line in Windows?
