我创建了一个简单的 Maven 项目,其中包含一个简单的 Controller 类,该项目仅显示服务器时间,但它从不经过 Controller ,很高兴获得任何帮助。

我的 Controller 类:

@Controller
@RequestMapping(value = "/")
public class Test
{
private static final Logger logger = LoggerFactory.getLogger(StudentsController.class);


@RequestMapping(value = "/", method = RequestMethod.GET)
public String home(Locale locale, Model model) {
logger.info("Welcome home! the client locale is "+ locale.toString());

Date date = new Date();
DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.LONG, DateFormat.LONG, locale);

String formattedDate = dateFormat.format(date);

model.addAttribute("serverTime", formattedDate );
System.out.println(formattedDate);

return "index";
}

}

<context:component-scan base-package="test" />
<mvc:default-servlet-handler/>


<!-- the mvc resources tag does the magic -->
<mvc:resources mapping="/resources/**" location="/resources/" />

<!-- also add the following beans to get rid of some exceptions -->
<bean
class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />
<bean
class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
</bean>

<!-- JSTL resolver -->
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass"
value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>

index.jsp

  <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<html>
<head>
<title>Spring RESTful Example</title>
</head>
<body>
<p>Your WebApplication is up and running....</p>

<div>
Server Time is:

<div>
${serverTime}

</div>
</div>
</body>
</html>

当我在 Tomcat 服务器上运行它时,输出是:

Your WebApplication is up and running....
Server Time is:
${serverTime}

请帮忙吗?

最佳答案

您还双重映射了您的请求...路径将是/index/index

去掉方法级别注解中的“value”参数,就可以保留“method”参数了。
