为什么我的 Java Web 应用程序中出现 NoSuchMethodError？

发布于 2025-01-11 06:25:24 字数 7829 浏览 0 评论 0原文

我已经根据我读过的教程设置了我的 spring-mvc webapp。

这是我的控制器类：

package hellowebapp;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HelloController {

    @RequestMapping("/hello")
    public String helloWorld(Model model) {
        model.addAttribute("message", "Hello World!");
        return "hello";
    }
}

这是我的 servlet.xml 文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:p="http://www.springframework.org/schema/p"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">

    <context:component-scan base-package="hellowebapp"/>

    <bean id="jspViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="prefix" value="/WEB-INF/views/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
    
</beans>

这是我的 web.xml 文件：

<web-app>    
    <servlet>
        <servlet-name>HelloWebapp</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>    
    <servlet-mapping>
        <servlet-name>HelloWebapp</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>
</web-app>

这是我的 hello.jsp 文件：

<%@ page contentType = "text/html; charset = UTF-8" %>
<html>
   <head>
      <title>Hello World</title>
   </head>
   
   <body>
      <h2>${message}</h2>
   </body>
</html>

这是我的 pom.xml 文件：

Why am I getting this error message? How can I make the webapp work as intended?

@ktm5124。在正常情况下，方法级别的响应序列化需要@controller，因此您可以包含以下示例。

@GetMapping("/{id}", produces = "application/json")
public @ResponseBody Book getBook(@PathVariable int id) {
    return findBookById(id);
}

@ktm5124. In normal @controller is required for response serialization in the method level so you could include the below sample.

@GetMapping("/{id}", produces = "application/json")
public @ResponseBody Book getBook(@PathVariable int id) {
    return findBookById(id);
}

Jetty 6.x 使用 Servlet 2.5，并且在 Servlet 3.x 中添加了 int javax.servlet.http.HttpServletResponse.getStatus()。 Spring框架5.x使用Servlet 3.x，因此您必须使用兼容的jetty版本。

如果您使用的是 Java 8，请将 maven-jetty-plugin maven 插件更新到至少 8.x 或更好的 9.x；如果您使用的是 Java 11 或更高版本，则更新到 10.x。

参考：

  1. https://www.eclipse.org/jetty/download.php#版本表
  2. https://spring.io/blog/2015/06/10/feedback-welcome-spring-5-system-requirements

Jetty 6.x uses Servlet 2.5 and the int javax.servlet.http.HttpServletResponse.getStatus() is added in Servlet 3.x. Spring framework 5.x uses Servlet 3.x so you must use compatible jetty version.

Update the maven-jetty-plugin maven plugin to at least 8.x or better 9.x if you are using Java 8 and if you are using Java 11 or later then update to 10.x.

Refs:

  1. https://www.eclipse.org/jetty/download.php#version-table

尝试在 pom.xml 中使用以下依赖项，因为旧版本不支持上述方法。

javax.servlet.http.HttpServletResponse.getStatus() 已在 Servlet 3.0 中添加

添加以下内容：

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

Try to use below dependency in pom.xml because mentioned method not supported in older versions.

javax.servlet.http.HttpServletResponse.getStatus() was added in Servlet 3.0

Add the following:

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