【中文标题】无法启动嵌入式容器;嵌套异常是 java.lang.IllegalArgumentException: Invalid <url-pattern> */ in servlet mapping Spring boot【英文标题】:Unable to start embedded container; nested exception is java.lang.IllegalArgumentException: Invalid <url-pattern> */ in servlet mapping Spring boot 【发布时间】:2015-12-26 20:20:50 【问题描述】:

我正在用球衣在 Spring Boot 中开发一个应用程序。我是Spring boot的新手。当我尝试在tomcat7.0中部署war时,出现以下错误

Spring 引导代码

@SpringBootApplication 
    public class Application extends SpringBootServletInitializer 

  @Override
    protected SpringApplicationBuilder configure
     (SpringApplicationBuilder application) 
        return application.sources(Application.class);
    

public static void main(String[] args) throws Exception
    SpringApplication.run(Application.class, args);



@Bean
public ServletRegistrationBean jerseyServlet()
    ServletRegistrationBean register = 
    new ServletRegistrationBean(new ServletContainer(),"*/");
    register.addInitParameter(ServletProperties.JAXRS_APPLICATION_CLASS, JerseyInitialization.class.getName());
    return register;

Jersey Configuration public class JerseyInitialization extends ResourceConfig

public JerseyInitialization() this.packages("in.vit.leasing.core.api");

【问题讨论】:

【参考方案1】:

异常(或者更确切地说是它的原因)会告诉你究竟出了什么问题:

在 servlet 映射中 */ 无效

在您的 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。你 可能想要/*

来自Java Servlet Specification:

在 Web 应用程序部署描述符中,使用以下语法来定义映射:

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。 ' 前缀用作扩展映射。 空字符串 ("") 是一种特殊的 UR L 模式,它精确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“/”字符的字符串表示应用程序的“默认”servlet。在这种情况下,servlet 路径是请求 URI 减去上下文路径,并且路径信息为空。 所有其他字符串仅用于完全匹配。
