HTTP状态500-处理程序处理失败；嵌套异常是java.lang.NosuchMethodError：

Question

我有jsp和html页面的应用程序

@Controller
public class LoginController {
    @RequestMapping(value = "/welcome", method = RequestMethod.GET)
    public String welcome() {
        System.out.println("==============21=========");
        return "welcome";
    }

    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String redirect() {
        System.out.println("==========1======");
        return "redirect:/LoginPage.html";
    }
}

HTTP Status 500 - Handler processing failed; nested exception is java.lang.NoSuchMethodError: javax.servlet.http.HttpServletResponse.getHeader(Ljava/lang/String;)Ljava/lang/String;

 type Exception report

说明服务器遇到一个内部错误，使其无法满足此请求。

例外

请让我知道我在哪里不及格。

Answer 1

HttpServletResponse.getHeader是Servlet3.0规范中的一种方法。我猜这与您的运行时环境不兼容。试着把这个加到你的POM上。

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.0</version>
    <scope>provided</scope>
</dependency>

如果这不起作用，请尝试调整使用IDE设置的运行时。您是否明确地告诉它在任何特定的服务器上运行？确保它与Servlet3.0兼容。因此，如果使用Tomcat，请确保它至少是Tomcat7。
