Question

我正在使用Java 8和Spring 5.1.5。我对此并不陌生，因此尝试遵循这些准则，但有一个问题似乎是跳过了DispatcherServlet和/或Controller映射，我在Tomcat中收到以下错误：

原始服务器找不到目标资源的当前表示，或者不愿意透露其存在。

我的web.xml：

我的Store-servlet.xml

<beans xmlns = "http://www.springframework.org/schema/beans"
   xmlns:context = "http://www.springframework.org/schema/context"

      <property name = "suffix" value = ".jsp" />
    </bean>

    <mvc:resources mapping="/resources/**" location="/resources/"/>

</beans>

我的控制器

package com.store.controller;

import org.apache.log4j.Logger;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;


@Controller
public class CarMartController {

    private transient Logger log = Logger.getLogger( "CarMartController" );


    @GetMapping("/store/carMart")
    public String navigateToCarMart( ModelMap model) {
        log.info("CarMartController [navigatetoCarMart");
        return "carMart";
    }
}

我的CarMart.jsp和标题

<%@ taglib prefix="c"   uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>

<html>

    <head>
        <link rel="stylesheet" type="text/css" href="/resources/css/styles.css" />
        <title>Car Mart</title>
    </head>
    <body style="background-image:url(/resources/images/carBackground.jpg);background-size:cover">
        <jsp:include page="./header.jsp" />
    </body>
</html>

<%@ taglib prefix="c"   uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
 <div class="navbar">
    <a href="<c:url value='/customer/customerDetail.jsp' />" >Customers</a>
    <a href="<c:url value='/car/carDetail.jsp' />" >Cars</a>
</div>

我拨打的网址是http://localhost:8088/store/carMart.jsp

资源目录位于war文件的webapps / store目录中

Answer 1

首先，为控制器类添加@RequestMapping：

@Controller
@RequestMapping("/store")
public class CarMartController {

    @GetMapping("/carMart")
    public String navigateToCarMart( ModelMap model) {
    ...
    }

}

并尝试使用http://localhost:8088/store/carMart
访问您的端点最后没有 .jsp 。
