java - 404 - 请求资源不可用 - Spring MVC

Question

我正在尝试在我的网站中使用 Spring 框架，但在尝试设置它时遇到了麻烦。我知道很多人都提出了与我的问题类似的问题，但我无法通过我所看到的所有提示来解决我的问题。

请参阅下面的代码，它尝试使用 Spring 框架打开 .jsp 文件。

web.xml

    </bean>

</beans>

OlaMundoController.java

package br.com.caelum.tarefas.controller;

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

@Controller
public class OlaMundoController {

    @RequestMapping("/olaMundoSpring")
    public String execute() {
        System.out.println("Executando a lógica com Spring MVC");
        return "ok";
    }
}

好的.jsp

<html>
  <body>
    <h2>Olá mundo com Spring MVC!</h2>
  </body>
</html>

我的项目

在此处输入图像描述

我正在使用 localhost:8080/WebProjetoFinal/olaMundoSpring 进行访问。

我在这里能错过什么？

编辑：

这是我初始化我的 TomCat 服务器或尝试访问页面时的完整堆栈跟踪。（两种情况的例外情况相同）

我认为您的 servlet 映射实际上应该是这样的：

<servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

score 0 · Accepted Answer

我相信您缺少文件 springmvc-servlet.xml

此文件源自您的调度程序 servle 的名称加上“-servlet.xml”

另外，尝试将您的组件扫描和 bean 定义移动到 springmvc-servlet.xml 文件中。

复制并粘贴 spring-context.xml 并将其重命名为 springmvc-servlet.xml
将组件扫描移动到 springmvc-servlet.xml
将 bean 定义移动到 springmvc-servlet.xml
将您的 serlvet 映射映射到“*.mvc”
让您的网页调用 /olaMundoSpring.mvc，这将调用调度程序 servlet

继续前进...（可选）还可以考虑使用 maven。它将使您不必在互联网上寻找 jar 文件。它将自动管理您的依赖项。

您的 spring-asm jar 似乎是错误的版本。试试spring-asm-3.1.1.RELEASE.jar。

我唯一能看到的另一件事是在 web.xml 中，将 init-param 更改为

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        /WEB-INF/spring-context.xml
    </param-value>
</context-param>

试试这些

删除 spring-asm-3.0.3.RELEASE.jar 看看它是否有效。
如果上述建议不起作用，请从这里下载 spring-asm-3.1.4 jar 而不是 spring-asm-3.0.3.RELEASE.jar并将其添加到您的 lib

我使用的是 Spring 3.1，迁移到 Spring 3.2 时出现以下错误：

nested exception is java.lang.IncompatibleClassChangeError: class
org.springframework.core.type.classreading.ClassMetadataReadingVisitor has interface 
org.springframework.asm.ClassVisitor as super class

解决方案：从 cxf 依赖项中排除 asm

<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-bundle-jaxrs</artifactId>
    <version>${cxf.version}</version>
    <exclusions>                
        <exclusion>
            <artifactId>spring-asm</artifactId>
            <groupId>org.springframework</groupId>
        </exclusion>
    </exclusions>
</dependency>

同样，排除造成问题的 asm 或其他 jar

删除 spring-asm-3.0.3.RELEASE.jar 看看它是否有效。

这解决了我的问题。谢谢
