Question

我正在使用平针织物开发春季靴子的应用程序。我是Spring的新手。当我尝试在tomcat7.0中部署战争时，我遇到以下错误

}

public class JerseyInitialization extends ResourceConfig{

public JerseyInitialization(){

}

}

Answer 1

例外（或更确切地说是其原因）告诉你到底出了什么问题：

servlet映射中的* /无效

在Java代码中，您尝试像这样实例化ServletRegistrationBean：

ServletRegistrationBean register = 
new ServletRegistrationBean(new ServletContainer(),"*/");

正如异常所说*/不是有效的servlet映射。您可能需要/*代替。

来自Java Servlet Specification：

在Web应用程序部署描述符中，以下语法用于定义映射：


以“/”字符开头并以“/ *”结尾的字符串   后缀用于路径映射。

以'*开头的字符串。 '前缀用作扩展名映射。

空字符串（＆＃34;＆＃34;）是一个特殊的UR L模式，它完全映射到应用程序的上下文根，即http://host:port/ /形式的请求。在这种情况下，路径信息是'/'，servlet路径和上下文路径是空字符串（“”）。

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null。

所有其他字符串仅用于完全匹配。

无法启动嵌入式容器;嵌套异常是java.lang.IllegalArgumentException：无效的<url-pattern> * /在servlet映射中Spring boot
