为什么war包在Windows的tomcat正常运行，在linux服务器报errorpage错误？
最近项目完成后打包成war发布到服务器遇到访问应用404问题，用的是tomcat8.5，错误信息如下：o.s.b.w.servlet.support.ErrorPageFilter : Cannot forward to error page for request [/login] as the response has already been committed. As a result, the response may have the wrong status code. If your application is running on WebSphere Application Server you may be able to resolve this problem by setting com.ibm.ws.webcontainer.invokeFlushAfterService to false项目是springboot+security+mybatis，ide 用的idea，打包方式用的是build菜单中的Build Artifactis
security配置
protected void configure(HttpSecurity http) throws Exception { http.authorizeRequests() //处理preflight请求 //.requestMatchers(CorsUtils::isPreFlightRequest).permitAll() .antMatchers("/user/login").permitAll() .antMatchers("/login").permitAll() .antMatchers("/login/error").permitAll() .anyRequest().authenticated() .and() //设置登录页 .formLogin() //设置登录成功页 .loginPage("/login") .successHandler(securityLoginSuccessHandler) .failureHandler(securityLoginFailureHandler) .and() .logout() .logoutUrl("/logout") .logoutSuccessHandler(securityLogoutSuccessHandler) .deleteCookies("JSESSIONID") .and() .sessionManagement() //session超时处理 .invalidSessionUrl("/login/invalid") .maximumSessions(1) //老用户被踢出后操作 .expiredSessionStrategy(new SecurityExpiredSessionStrategy()); http.csrf().disable() .exceptionHandling().accessDeniedHandler(securityAccessDeniedHandler);}loginpage的“/login”配置如下:
@RequestMapping("/login")public String showLogin() throws IOException { System.out.println("调用loginController的登录方法"); return "index.html#/login";}遇到这个问题时，参考https://blog.csdn.net/weixin_41622183/article/details/84652437
这篇博客在启动类加入配置：
public class KpApplication extends SpringBootServletInitializer { public static void main(String[] args) { SpringApplication.run(KpApplication.class, args); } @Bean public ErrorPageFilter errorPageFilter() { return new ErrorPageFilter(); } @Bean public FilterRegistrationBean disableSpringBootErrorFilter(ErrorPageFilter filter) { FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(); filterRegistrationBean.setFilter(filter); filterRegistrationBean.setEnabled(false); return filterRegistrationBean; }}重新打包发布到linux服务器，新的错误信息为: o.s.b.d.LoggingFailureAnalysisReporter :
***************************
APPLICATION FAILED TO START
***************************
Description:
The bean 'errorPageFilter', defined in org.springframework.boot.web.servlet.support.ErrorPageFilterConfiguration, could not be registered. A bean with that name has already been defined in com.kpzdh.kp.KpApplication and overriding is disabled.
Action:
Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true
然后参考:https://blog.csdn.net/weixin_42633131/article/details/84782516 这篇博客，在yml配置中加入配置：
spring: jmx: default-domain: demo datasource: driver-class-name: com.mysql.cj.jdbc.Driver url: jdbc:mysql://localhost:3306/demo?useUnicode=true&characterEncoding=utf-8&useSSL=true&serverTimezone=GMT%2B8 username: root password: root main: allow-bean-definition-overriding: true 如上配置之后，两个错误信息都没有出现了，但是还是404，查看日志，"/login"路径的"调用loginController的登录方法"已经输出了，但是浏览器控制台中，/login路径还是404，请问该如何解决呢？这个问题已经困扰很久了，希望大家能帮帮我，万分感谢！ |
