Answer 1

如果您认为错误与编码有关，请在命名空间中查找该类。

在这种情况下，com.testcomp.mact.web.filter.AuthorizationFilter.doFilter(AuthorizationFilter.java:70)对我来说看起来不是任何已知的框架，所以我认为它是您控制下的代码。

Answer 2

您正在尝试将String包含的日期值转换为Long值。在第70行修改AuthorizationFilter.doFilter以确保您传递有效的输入parseLong调用。如果您对输入值没有任何控制权，可以尝试下面的内容

 try {
         long l = Long.parseLong(s);
         System.out.println("long l = " + l);
      } catch (NumberFormatException e) {
         log.error("NumberFormatException: " + nfe.getMessage()); 
          //Redirect your request to error page saying invalid input

      }

Answer 3

com.testcomp.mact.web.filter.AuthorizationFilter.doFilter（AuthorizationFilter.java:70） - 这里方法doFilter（...）行号70 ..你试图转换字符串Thu Oct 18 13到龙。这就是错误。

如何跟踪抛出异常的文件？
