Question

我的Web应用程序使用从Tomcat的/ webapps /文件夹开始的根路径作为应用程序根目录而不是WEB-INF文件夹。谁能告诉我配置错误的地方？

难度：它很混乱，因为转到索引页面工作正常。令人困惑的是RequestMapping工作正常，我可以看到Hibernate进行SQL查询，这意味着自动服务的服务（和存储库）被称为OK。

以下是我的配置文件：

的web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
         xmlns="http://java.sun.com/xml/ns/javaee" 
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
  <servlet>
        <servlet-name>city-http</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>/WEB-INF/city-http-servlet.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>city-http</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

</web-app>

城市-HTTP-servlet.xml中

IndexController工作正常：

package nikzgs.city.app.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class IndexController {

    @RequestMapping("/")
    public String index() {
        return "index";
    }
}

/ WEB-INF / jsp /文件夹下的index.jsp显示OK：

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@taglib uri="http://www.springframework.org/tags" prefix="spring"%>

    <br />
    <a href="/city/viewList">View cities without context path</a>

</html>

CityController：

package nikzgs.city.app.controller;

import java.util.List;

import nikzgs.city.app.entity.City;
import nikzgs.city.app.service.CityService;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;

@Controller
@RequestMapping("/city")
public class CityController {

    @Autowired
    private CityService cityService;

    @RequestMapping(value = "/viewList",  method = RequestMethod.GET)
    public String cityViewForm(Model model) {
        return prepareCityListForReview(model);
    }

    @RequestMapping(value = "/addNewCity",  method = RequestMethod.POST)
    public String addNewCity(@ModelAttribute("newCity") City newCity, Model model) {
        cityService.addCity(newCity);
        return prepareCityListForReview(model);
    }

    @RequestMapping(value = {"/editCity","/modifyCity"},  method = RequestMethod.GET)
    public String viewEditCityForm(@ModelAttribute("cityUnderEdit") City cityUnderEdit, @RequestParam("id")Long id, Model model) {
        if (null != id) {
            City cityToEdit = cityService.getCityById(id);
            model.addAttribute("cityUnderEdit", cityToEdit);
        }
        return "city/cityEdit";
    }

    @RequestMapping(value = "/updateCity",  method = RequestMethod.POST)
    public String updateCity(@ModelAttribute("cityUnderEdit") City cityUnderEdit, Model model) {
        cityService.updateCity(cityUnderEdit);
        return prepareCityListForReview(model);
    }

    @RequestMapping(value = "/deleteCity",  method = RequestMethod.GET)
    public String deleteCity(@RequestParam("id")Long id, Model model) {
        if (null != id) {
            cityService.deleteCityById(id);
        }
        return prepareCityListForReview(model);
    }

    private String prepareCityListForReview(Model model) {
        List<City> cities = cityService.getAllCities();
        model.addAttribute("cities", cities);
        model.addAttribute("newCity", new City());
        return "city/cityList";
    }
}

此外，2个包含网址和文件夹结构的屏幕截图，我相信它们会有所帮助 wrong path

索引确定：

index ok

Answer 1

变化

<property name="prefix" value="WEB-INF/jsp/"/>

到

<property name="prefix" value="/WEB-INF/jsp/"/>

还使用JSTL核心代码库<c:url value='/some-path'/>输出正确的网址

Spring InternalResourceViewResolver不使用WEB-INF作为root进行查看
