我有一个带有单个控制器类(MainController.class)的war项目,它带有一个公共函数index(),它返回一个字符串,这是我最后一次检查你要转发到的视图的名称 - 以及一个单独的jsp命名" index.jsp"。视图位于/ main / webapp / WEB-INF / views / jsp /中。 MainController.java:
@Controller
public class MainController
{
@Autowired
private ApplicationContextProvider mObjApplicationContextProvider;
@Autowired
private ScheduleService mObjScheduleService;
protected ApplicationContext getApplicationContext()
{
return(getApplicationContextProvider().getApplicationContext());
}
protected ApplicationContextProvider getApplicationContextProvider()
{
return(mObjApplicationContextProvider);
}
protected Object getBean(final Class<?> clsBean)
{
return(getApplicationContext().getBean(clsBean));
}
protected Object getBean(final String sBeanName)
{
return(getApplicationContext().getBean(sBeanName));
}
protected ScheduleService getScheduleService()
{
return(mObjScheduleService);
}
@RequestMapping(value="/")
public String index()
{
return("index");
}
}
的index.jsp:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
Hello World!
</body>
</html>

出于某种原因,当我转到&#34; http://localhost:8080/Ushering/&#34;:404 - &#34时,我的浏览器出现错误:请求的资源不可用。&#34;
我无法在日志中找到任何内容(但必要时可以发布)告诉我哪些文件或资源无法使用。它似乎能够找到控制器,因为在一个日志文件中它提到了控制器的请求映射。它可能是什么?
编辑:WAR文件是在pom文件中定义的Ushering,也是在web.xml中定义的项目名称,所以我认为上下文也是Ushering以及Spring应用程序中的任何东西如果我将请求映射设置为/ Hello,那么URL应该是localhost:8080 / Ushering / Hello。
编辑:我的Web.xml文件

答案 0 :(得分:1)
如果查看MainController类,只有一个请求处理方法返回&#34; index&#34;。它被映射到&#34; /&#34;这意味着当您键入 localhost:8080 时,它会为您提供索引文件。因此,不要输入 localhost:8080 / Ushering ,而是输入 localhost:8080 。它会工作。但是如果要输入 localhost:8080 / Ushering ,请将控制器文件中的请求映射更改为以下内容。
@RequestMapping(值=&#34; /迎来&#34)
public String index()
{
return("index");
}
它会返回索引文件。
