uj5u.com熱心網友回復：
at com.itheima.web.filter.EncodingFilter.doFilter(EncodingFilter.java:36)這是一個什么東西？
uj5u.com熱心網友回復：
我也不知道是個什么東西，算了我放棄了，我不做了，太難了，不適合我，打擾長得帥的了uj5u.com熱心網友回復：
這種情況是由于Maven配置了tomcat，但是沒有在Maven專案中匯入jsp-api的jar包的時候，此時eclipse會報錯，匯入jar包之后eclipse不會報錯，但運行的時候會自動把tomcat中jsp-api和javax.servlet-api一起匯入，導致jar包重復了，就會出現如上問題。uj5u.com熱心網友回復：
謝謝你，雖然我也看不懂uj5u.com熱心網友回復：
我也不懂..uj5u.com熱心網友回復：
