springboot 部署到tomcat6遇到404的问题

springboot 部署到tomcat6遇到404的问题,其实是因为springboot只支持servlet2.5以上的,tomcat6是2.5以下的导致报错,参考如下网址:

   注:如果你的tomcat是tomcat6版本,那很大可能你会遇到如下两个问题:

第一个问题是: 当你按照网上的配置,配置tomcat时,放在tomcat6下面,会遇到如下问题,我的解决方案是删除掉webapps对应项目lib文件夹下的tomcat-embed-core-8.5,但是启动仍然报错,接着看下一步:

信息: validateJarFile(D:\allone\ex2.6\Ex02-Bank\tomcat6113\webapps\RuoYi\WEB-INF\lib\tomcat-embed-core-8.5.31.jar) - jar not loaded. See Servlet Spec 2.3, section 9.7.2. Offending class: javax/servlet/Servlet.class

    这个上面的文章有说:是因为

     所以当我遇到这个问题之后,我尝试更换成tomcat8,不需要额外配置web.xml或者引入

   启动就正常,就能够访问项目了.总结一下当你遇到404的错误时,请先确认一下你的tomcat是否为8,请更换成tomcat8,即可解决问题:

   注意别忘了在tomcat的server.xml配置的你的项目war包名称:

   我的启动java类和pom.xml文件如下:

package com.ruoyi;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

/**
 * web容器中进行部署
 * 
 * @author ruoyi
 */
public class RuoYiServletInitializer extends SpringBootServletInitializer
{
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application)
    {
        return application.sources(RuoYiApplication.class);
    }

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

}
