Java 弹簧控制器
我试图遵循Spring教程,但一直收到404错误。下面是我的控制器类:Java 弹簧控制器,java,spring-mvc,spring-annotations,Java,Spring Mvc,Spring Annotations,我试图遵循Spring教程,但一直收到404错误。下面是我的控制器类: @Controller @RequestMapping("/updatedescription.htm") public class UpdateDescriptionController { /** Logger for this class and subclasses */ protected final Log logger = LogFactory.getLog(getClass());
@Controller
@RequestMapping("/updatedescription.htm")
public class UpdateDescriptionController {
/** Logger for this class and subclasses */
protected final Log logger = LogFactory.getLog(getClass());
@Autowired
private ProductManager productManager;
@RequestMapping(value="/{description}", method=RequestMethod.GET)
public String updateDescription(@PathVariable("description") String description, Model model) {
return "redirect:/hello.htm";
}
@Autowired
public UpdateDescriptionController(ProductManager productManager) {
this.productManager = productManager;
}
}
当我试着去“http://localhost:8505/baseSpringMVC/updatedescription.htm/Chair“我得到一个404错误
我已将web.xml文件设置为将所有*.htm流量指向DispatcherServlet

任何帮助都会很好
谢谢大家! 将/Chair添加到末尾时,它不是*.htm。发布您的web.xml,以便我们可以调试它。将方法更改为Post,测试它,并让我知道,以便我们可以进一步调试
@RequestMapping(value="/{description}", method=RequestMethod.POST)
删除控制器上的顶级RequestMapping注释。updateDescription方法将指定请求映射。类级请求映射不应包含“.htm”。即改变:
@RequestMapping("/updatedescription.htm")
到
如果这不能解决问题,我们可能需要查看您的Spring配置文件
编辑:
Spring配置文件的顶部,包括MVC名称空间,应该如下所示:
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:oxm="http://www.springframework.org/schema/oxm"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
http://www.springframework.org/schema/oxm http://www.springframework.org/schema/oxm/spring-oxm-3.0.xsd">
这也不起作用。它来自一个链接,所以我相信它一定是一个GET。你有下面的一行吗:是的,在baseSpringMVC-servlet.xml文件中。否,我在工作,他们在这里屏蔽这些站点。它来自Spring教程,您在配置部分15.3.2中有什么想法。表示您可以使用顶级控制器,每个方法都有另一个mappingupdated链接是的,您可以,但它至少不应该包含“.htm”扩展名。您应该使URL等效于“”。请按照下面的建议进行尝试。我将添加我的*-servlet.xml文件尝试将其添加到Spring配置文件:
Stacktrace:org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException:ServletContext资源[/WEB-INF/BaseS普林gMVCServlet.xml]的xml文档中的第14行无效;嵌套异常为org.xml.sax.saxpasseeption:元素“mvc:annotation-driven”的前缀“mvc”未绑定。在org.springframework.beans.factory.xml.XmlBeanDefinitionReader.doLoadBeanDefinitions(XmlBeanDefinitionReader.java:396)的org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:334)中,您需要在文件顶部定义mvc命名空间。所以您需要xmlns:mvc=”http://www.springframework.org/schema/mvc“
和xsi:schemalocation
中,您需要http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
。请您澄清一下,以便我可以剪切和粘贴。
