java - Spring创建bean时出错FileNotFoundException

标签 java spring hibernate maven spring-mvc

我将 Intellij 与 Spring 和 Hibernate 结合使用。 每当我使用 Tomcat 部署应用程序时，我都会遇到这个奇怪的错误。

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'testController' defined in file [C:\Users\Pawel\IdeaProjects\Spring2\target\com.pawel-1.0-SNAPSHOT\WEB-INF\classes\com\pawel\controller\TestController.class]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.pawel.controller.TestController]: Constructor threw exception; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [WEB-INF/TestServlet-servlet.xml]; nested exception is java.io.FileNotFoundException: class path resource [WEB-INF/TestServlet-servlet.xml] cannot be opened because it does not exist

但我确实有那个文件。即使当我在“...context = new ClassPathXmlApplicationContext("")”中执行 CTRL+SPACE 时，它也会检测到它并自动完成它，如下所示。我问了 friend ，但没有人能帮助我。另外，当我在 spring.xml 中添加其他bean时，出现了这个问题，当我只有最后一个bean(没有 hibernate )时，问题没有出现

网络浏览器中显示的错误是 HTTP 状态 500 - Servlet TestServlet 的 Servlet.init() 引发异常

@Controller
@RequestMapping("/")
public class TestController {

    ConfigurableApplicationContext context = new ClassPathXmlApplicationContext("WEB-INF/TestServlet-servlet.xml");

    PersonDAO personDAO = context.getBean(PersonDAO.class);

    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String testView(ModelMap model){
        Person person = new Person();
        person.setAge(10);
        person.setName("John");
        person.setLastName("Smith");
        personDAO.save(person);
        model.addAttribute("person", person);

最佳答案

带有错误消息 嵌套异常是java.io.FileNotFoundException:类路径资源[WEB-INF/TestServlet-servlet.xml]无法打开，因为它不存在 => tomcat 未检测到该文件。

你必须把他放在WEB-INF下，并且你必须将你的war/jar部署在~\tomcat\webapps下。当您部署它时，您将拥有一个与您的 war\jar 同名的文件夹，您可以检查您的 TestServlet-servlet.xml 是否存在？您还可以通过使用 winrar 打开您的 war/jar 来检查您的文件是否存在。
