1. 问题描述
   在使用maven打包（package）springboot项目为war项目后，在本地机器上使用Tomcat跑这个项目，访问资源时出现下面的错误：

o.s.b.w.servlet.support.ErrorPageFilter  : Cannot forward to error page 
for request [/test] as the response has already been committed. As a 
result, the response may have the wrong status code. If your applicationis running on WebSphere Application Server you may be able to resolve this problem by setting com.ibm.ws.webcontainer.invokeFlushAfterServiceto false

参考了很多办法，有说在启动类中添加如下代码可以解决：

@Beanpublic ErrorPageFilter errorPageFilter() {return new ErrorPageFilter();}@Beanpublic FilterRegistrationBean disableSpringBootErrorFilter(ErrorPageFilter filter) {FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();filterRegistrationBean.setFilter(filter);filterRegistrationBean.setEnabled(false);return filterRegistrationBean;}

还有包括在pom文件中注释掉内嵌的Tomcat依赖的解决办法。

但是我尝试无果。

2. 解决办法
   
   引入文件的话，一定要记得将resources目录下的文件引入到类路径下：

src/main/resources**/*.*
