我使用Maven和Eclipse 4.5创建了一个Spring MVC应用程序 但是，在tomcat上部署之后，我得到404.无法理解我哪里出错了？
这是我的文件 - AppConfig.java
import org.springframework.context.MessageSource;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.support.ResourceBundleMessageSource;

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.pratiksanglikar.controller")
public class AppConfig {
@Bean
public ViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setViewClass(JstlView.class);
viewResolver.setPrefix("/WEB-INF/views/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
@Bean
public MessageSource messageSource() {
ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
messageSource.setBasename("messages");
return messageSource;
}
}
AppInitializer.java
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 AppInitializer implements WebApplicationInitializer {
public void onStartup(ServletContext container) throws ServletException {
AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ctx.register(AppConfig.class);
ctx.setServletContext(container);
ServletRegistration.Dynamic servlet = container.addServlet(
"dispatcher", new DispatcherServlet(ctx));
servlet.setLoadOnStartup(1);
servlet.addMapping("/");
}
}
AppController.java
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.MessageSource;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import com.pratiksanglikar.service.UserService;
@Controller
public class AppController {
UserService service;
@Autowired
MessageSource messageSource;
/*
* This method will be called on form submission, handling POST request for
* saving employee in database. It also validates the user input
*/
@RequestMapping(value = "UserLogin" , method = RequestMethod.GET)
public String Login() {
return "User Logged In Successfully";
}
}
UserService.java
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.transaction.annotation.Transactional;
import com.pratiksanglikar.crossover.dao.UserDAO;
import com.pratiksanglikar.crossover.model.User;
@Component
@Transactional
public class UserService {
@Autowired
private UserDAO dao;
public User findByUsername(String userName) {
return dao.findByUsername(userName);
}
}
当我部署并点击网址时 - localhost：8080 / CO / UserLogin.jsp，我在apache tomcat console上遇到以下错误 -

答案 0 :(得分：0)
在AppInitializer.java中试试这个
servlet.addMapping("/*");
而不是
servlet.addMapping("/");
答案 1 :(得分：0)
我认为
@ComponentScan(basePackages = "com.pratiksanglikar.controller")
也应该包括你的root包，例如
@ComponentScan(basePackages = {"the.root.package.of.your.app", "com.pratiksanglikar.controller"})
