java.lang.IllegalArgumentException：servlet映射中的<url-pattern> SolrServlet1无效

标签： tomcat servlets illegalargumentexception url-pattern servlet-mapping

我已经创建了一个JSP页面，我将从这个页面调用一个servlet并处理一些东西并重定向回到同一个JSP。

但是当我只部署JSP时，一切都很好。但是当我在项目中包含我的servlet时，tomcat 8无法启动并且它会抛出错误。

我以下列方式定义了我的web.xml 

<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">   <display-name>SearchBoxcComp</display-name>   <welcome-file-list>
    <welcome-file>SearchBoxNew.jsp</welcome-file>   </welcome-file-list>   <servlet>
    <servlet-name>SolrServlet1</servlet-name>
    <servlet-class>Servlets.SolrServlet1</servlet-class>   </servlet>

  <servlet-mapping>
    <servlet-name>SolrServlet1</servlet-name>
    <url-pattern>SolrServlet1</url-pattern>   </servlet-mapping> </web-app>

请帮我解决此问题

2 个答案:

答案 0 :(得分：3)

如果我查看您的错误日志，则说它是由

引起的 
/SolrServlet1

请在您的网址格式中使用SolrServlet1代替Future（基本上预先设置正斜杠）并检查结果。

网址格式规范：

  
      
  1. 以“/”字符开头并以“/ *”后缀结尾的字符串用于路径映射。
    2.   
  2. 以'*。'前缀开头的字符串用作扩展名映射。
    3.   
  3. 仅包含'/'字符的字符串表示＆＃34;默认＆＃34;应用程序的servlet。在这种情况下，servlet路径是请求URI减去上下文路径，路径信息为空。
    4.   
  4. 所有其他字符串仅用于完全匹配。
    5.   

答案 1 :(得分：0)

我有一个类似的问题...... 通过在web.xml中添加“/”来解决它

这里似乎是同一个问题 你的代码看起来像

 `<url-pattern>SolrServlet1</url-pattern>`

正确的方法是添加'/'  <url-pattern>/SolrServlet1</url-pattern>
