http.addFilterBefore(jwtAuthenticationTokenFilter(),UsernamePasswordAuthenticationFilter.class)为何报错，如何修改

根据引用内容来看，问题是关于报错和如何修改的。根据引用中的信息，需要修改的地方有MyAuthenticationSuccessHandler，JwtAuthenticationTokenFilter和SpringSecurityConfig三个地方，删除与JWT相关的内容即可。在引用中提到的自定义认证失败处理器可能也需要进行相应修改。具体的修改代码可以参考引用中给出的文章。至于关于"报错"并没有提供具体的错误信息，所以无法给出具体的修改建议。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
