标签： java eclipse spring spring-mvc

我正在使用spring 4.0.2，eclipse z，JEE marse。我必须从here测试一个例子。我的项目结构是：

Tomcat v7.0

我Java Resources src com.test.config HelloConfig.java HelloController.java HelloInitializer.java WebContent META-INF MANIFEST.MF WEB-INF lib view welcome.jsp 的内容是：

HelloConfig.java

我package com.test.config; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.ComponentScan; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.ImportResource; import org.springframework.web.servlet.ViewResolver; import org.springframework.web.servlet.config.annotation.EnableWebMvc; import org.springframework.web.servlet.view.InternalResourceViewResolver; import org.springframework.web.servlet.view.JstlView; @Configuration @EnableWebMvc @ComponentScan(basePackages = "com.test.config") public class HelloConfig { @Bean public ViewResolver viewResolver() { InternalResourceViewResolver viewResolver = new InternalResourceViewResolver(); viewResolver.setViewClass(JstlView.class); viewResolver.setPrefix("/WEB-INF/view/"); viewResolver.setSuffix(".jsp"); return viewResolver; } } 的内容：

HelloInitializer.java

我package com.test.config; import javax.servlet.ServletContext; import javax.servlet.ServletException; import javax.servlet.ServletRegistration; import org.springframework.web.WebApplicationInitializer; import org.springframework.web.context.support.AnnotationConfigWebApplicationContext; import org.springframework.web.servlet.DispatcherServlet; public class HelloInitializer implements WebApplicationInitializer { public void onStartup(ServletContext container) throws ServletException { AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext(); ctx.register(HelloConfig.class); ctx.setServletContext(container); ServletRegistration.Dynamic servlet = container.addServlet("dispatcher", new DispatcherServlet(ctx)); servlet.setLoadOnStartup(1); servlet.addMapping("/hello/*"); } } 的内容：

HelloController.java

但我在服务器上运行此项目并收到此错误：

package com.test.config;

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

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

    @RequestMapping(method = RequestMethod.GET)
    public String sayHello(ModelMap model) {
        model.addAttribute("greeting", "Hello World from Spring 4 MVC");
        return "welcome";
    }

    @RequestMapping(value = "/helloagain", method = RequestMethod.GET)
    public String sayHelloAgain(ModelMap model) {
        model.addAttribute("greeting", "Hello World Again, from Spring 4 MVC");
        return "welcome";
    }
}

我使用此代码而不是上一个org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [applicationContext.xml]; nested exception is java.io.FileNotFoundException: class path resource [applicationContext.xml] cannot be opened because it does not exist at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:343) at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:303) at org.springframework.beans.factory.support.AbstractBeanDefinitionReader.loadBeanDefinitions(AbstractBeanDefinitionReader.java:180) at org.springframework.beans.factory.support.AbstractBeanDefinitionReader.loadBeanDefinitions(AbstractBeanDefinitionReader.java:216) at org.springframework.beans.factory.support.AbstractBeanDefinitionReader.loadBeanDefinitions(AbstractBeanDefinitionReader.java:187) at org.springframework.web.context.support.XmlWebApplicationContext.loadBeanDefinitions(XmlWebApplicationContext.java:125) at org.springframework.web.context.support.XmlWebApplicationContext.loadBeanDefinitions(XmlWebApplicationContext.java:94) at org.springframework.context.support.AbstractRefreshableApplicationContext.refreshBeanFactory(AbstractRefreshableApplicationContext.java:129) at org.springframework.context.support.AbstractApplicationContext.obtainFreshBeanFactory(AbstractApplicationContext.java:540) at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:454) at org.springframework.web.context.ContextLoader.configureAndRefreshWebApplicationContext(ContextLoader.java:403) at org.springframework.web.context.ContextLoader.initWebApplicationContext(ContextLoader.java:306) at org.springframework.web.context.ContextLoaderListener.contextInitialized(ContextLoaderListener.java:106) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:5014) at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5524) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1575) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1565) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: java.io.FileNotFoundException: class path resource [applicationContext.xml] cannot be opened because it does not exist at org.springframework.core.io.ClassPathResource.getInputStream(ClassPathResource.java:158) at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:329) ... 21 more Jul 27, 2016 10:14:38 AM org.apache.catalina.core.StandardContext startInternal SEVERE: Error listenerStart Jul 27, 2016 10:14:38 AM org.apache.catalina.core.StandardContext startInternal SEVERE: Context [/HelloMVC] startup failed due to previous errors Jul 27, 2016 10:14:38 AM org.apache.catalina.core.ApplicationContext log INFO: Closing Spring root WebApplicationContext Jul 27, 2016 10:14:38 AM org.apache.catalina.core.StandardContext listenerStop SEVERE: Exception sending context destroyed event to listener instance of class org.springframework.web.context.ContextLoaderListener java.lang.IllegalStateException: BeanFactory not initialized or already closed -

HelloInitializer.java

但我收到了这个错误：

package com.test.config;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class HelloInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return null;
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class[] { HelloConfig.class };
    }

    @Override
    protected String[] getServletMappings() {
        return new String[] { "/" };
    }
}

如何解决此错误？

2 个答案:

答案 0 :(得分：2)

您的前控制器（称为Dispatcherservlet）无法找到您的Config类。 试试这个 

@ComponentScan(basePackages = "com.test")
public class HelloConfig { }

或

@ComponentScan(basePackages = "com.test.*")
public class HelloConfig { }

而不是

@ComponentScan(basePackages = "com.test.config")
public class HelloConfig {}

答案 1 :(得分：1)

你已经分享了你的文件夹结构：

Java Resources 
    src
        com.test.config 
            HelloConfig.java
            HelloController.java
            HelloInitializer.java
WebContent
    META-INF
        MANIFEST.MF
    WEB-INF
        lib
        view
            welcome.jsp

我在这里找不到WEB_INF中的HelloConfig-servlet.xml。如果你真的在WEB-INF中有这个但是在某种程度上错过了它，我会建议你检查你的构建路径配置。我的猜测是某种方式WEB-INF没有在构建路径中注册
