Spring mvc基于Java的配置无法正常工作。控制台显示没有错误，但我的jsp页面没有显示 [英] Spring mvc Java based Configuration not working. Console display no error but my jsp page is not showing
本文介绍了Spring mvc基于Java的配置无法正常工作。控制台显示没有错误，但我的jsp页面没有显示的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
你好，我正在将我的简单演示项目从bean配置转换为纯java基础配置。 Bean配置可以很好地创建表和全部。但我的java配置不显示任何页面。我解决了许多错误，现在控制台显示没有指定问题的错误。这里是我的代码，请找出最新的错误，或者我错过了配置中的任何东西。我对Spring很陌生，对于基于java的配置来说相当新颖。这些是我从中获取代码的网站。

只添加了这些新类。我删除了我的web.xml。
稍后我将添加Spring Security配置类

Myindex.jsp文件位于WEB-INF / views文件夹下的文件夹
视图可以通过bean配置正确解析。
解决方案谢谢您的回答。我发现了这个问题。当我在我的MvcConfiguration类的顶部写了@ComponentScan时，它工作并且显示页面。
Hello i am converting my simple demo project from bean configuration to pure java based configuration. Bean configuration works fine creating tables and all. But my java configuration is not displaying any pages. I solved many errors bur now console shows no error specifying the problem. here's my code please find whats wrong, or have i missed anything in the configuration. I am new to spring and fairly new to java based configuration. These are the sites from which i took code.

for hibernate i use used this tutorial

resolver.setSuffix(".jsp");
return resolver;
}
}
3.RepositoryConfiguration

return dataSource;
}
@Bean
@Autowired
public HibernateTransactionManager transactionManager(SessionFactory s) {
HibernateTransactionManager txManager = new HibernateTransactionManager();

return txManager;
}
}
4.SpringConfigurationInitializer
package com.kharoud.configuration.initilizer;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;
import com.kharoud.configuration.AppConfiguration;
public class SpringConfigurationInitializer extends AbstractAnnotationConfigDispatcherServletInitializer{
@Override
protected Class<?>[] getRootConfigClasses() {
return new Class[] { AppConfiguration.class };
}
@Override
protected Class<?>[] getServletConfigClasses() {
// TODO Auto-generated method stub
return null;
}
@Override
protected String[] getServletMappings() {
return new String[] { "/" };
}
}
only added these new classes. I deleted my web.xml.
Later on i will add Spring Security configuration class
this is my console output

MyHomeController
package com.kharoud;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class HomeController {
@RequestMapping("/")
public String welcome(Model model){
return "index";
}
}
Myindex.jsp file is in WEB-INF/views folder under webapp folder
The views were properly resolved with bean configuration.
解决方案 Thank you for your answers. I found the problem. When i wrote @ComponentScan on top of my MvcConfiguration class it worked and pages are displaying.
这篇关于Spring mvc基于Java的配置无法正常工作。控制台显示没有错误，但我的jsp页面没有显示的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
