Caused by: java.lang.IllegalArgumentException: Invalid #write/* in servlet mapping
检查你的servlet mapping

1.web.xml 中对于 url-pattern 部分的配置错误
2.web.xml 中 servlet 和 servlet-mapping 中的 servlet-name 没有对应起来

注意看下日志文件里面的报错信息,再去百度这个错误。

Tomcat ClassNotFoundException: java.util.logging.Logger

昨天一直在配置Tomcat,一直都是闪退不报错。后来发现了一篇文章[Tomcat 启动闪退,如何查看错误信息](https://blog.csdn.net/u014368040/article/details/84023574 "")如文章一样修改之后发现了报错的原因,但是这个报错貌似好多人都没有(大多数人都是Tomcat启动的时候没有问题的,在部署项目的时候才出了问题。然而我这个是在tomcat配置的时候就不行了呀T T)也一直找不到解决的办法。给大佬们看看我的报错,有没有解决办法![图片说明](https://img-ask.csdn.net/upload/201911/04/1572850503_146582.jpg)</br>有些说是catalina.bat文件被修改过了(不是绿色文件),但是我感觉有点不太合适我这个。因为我是JDK12,jdk12/lib中一个jar文件都没有,如下图:![图片说明](https://img-ask.csdn.net/upload/201911/04/1572850719_43842.jpg)</br>所以会不会是这个原因呢....jdk是在官网下的。希望有大佬解答一下QAQ

java.util.ArrayList cannot be cast to byte[]

类型不能强制转换,但是我这个并没看出来哪里需要转换,请大家帮忙看一看哪里出问题了。 我在一个activity将bitmap转为byte[]类型,装入List里面,通过gson把这个list变为json类型,再传到另一个activity,解析json数据再转为List。 代码比较长,我就不全列出了。就用log来提供内容吧。 private List<byte[]> mBitmaps = new ArrayList<>(); ...... Log.i(TAG, "getView: "+mBitmaps.get(i)); Log.i(TAG, "getView: "+mBitmaps); Log.i(TAG, "getView: "+mBitmaps.getClass()); if (mBitmaps != null) { Glide.with(mContext).load(mBitmaps.get(i)).into(viewHolder.imageView); } 打印的内容就是 getview:[... , ...] getview:[[... , ...] getView: class java.util.ArrayList 报错就是在Glide那一行, ...就省略了就是-128到128一堆数字。 还需要什么信息就说一下。

java.util.regex.PatternSyntaxException

抛出这个异常,java.util.regex.PatternSyntaxException 异常的代码是这个: String Jstr = (((value.replaceAll(", ", "\",\"")) .replaceAll("=", "\":\"")).replace("{", "{\"")) .replace("}", "\"}") .replaceAll("}\",\"{", "},{"); 到底哪儿错了啊。。。

为啥我读取gz文本内容,总是报错java.util.zip.ZipException: Not in GZIP format?

总是读取不了gz文本 ``` try { BufferedReader reader = new BufferedReader(new InputStreamReader( new GZIPInputStream( new FileInputStream("D:/Ericsson/data/qixx/logs/20190101/sog03_log-20190101.txt.gz")), "iso-8859-1")); String line = null; while ((line = reader.readLine()) != null) { System.out.println(line); } } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } ```

Java报错,各位大神帮忙看看:java.lang.NoClassDefFoundError

![图片说明](https://img-ask.csdn.net/upload/201602/22/1456119826_44373.gif) 代码如下: com.asiainfo.crm.open.base.bo.IOpenLogical iOpenLogical = IUcmCoreFactory.getICenterSV()._getICenterByBillId(aBillId); 上面代码执行时跳到下面代码,随后报错: public static ICenterSRV getICenterSV() throws IOpenException,Exception{ return (ICenterSRV)OpenServiceFactory.getService( ICenterSRV.class ); }

java.util.ArrayList类

初学java,请问为什么将ArrayList对象get方法的返回值赋给一个引用,操作这个引用不会影响ArrayList对象内对应元素呢? List<String> list = new ArrayList<String>(); list.add("abc"); String stri = list.get(0); stri += "def"; System.out.println(stri); System.out.println(list); 输出结果为: abcdef [abc] 但是我看到的ArrayList的get方法就是在判断index是否超范围之后直接return (E) elementData[index];为什么对引用stri的操作不会改变list的元素呢? 刚开始学java,很多东西没弄清楚,求前辈指点一下.m(__)m

Scanner中异常: java.util.NoSuchElementException?

public void RemoveTest() { Scanner input = new Scanner(System.in); System.out.println("Please input Id wanted to delete:"); String idString=null; while (true) { idString = input.next(); Student student = map.get(idString); if (student == null) { System.out.print("Not exists this student,Please input again:"); continue; } else { map.remove(idString); break; } } input.close(); } 这个方法里面 idString = input.next();一直出现上述错误,Student是我写的一个类,没问题
