我正在创建的 spring/hibernate Web 应用程序正在正确构建和部署,但是在尝试访问 WEB-INF/jsp 文件夹中的 jsp 页面时遇到了一些问题。我放置在 WebContent 文件夹中的测试 jsp 页面正确打开。

这是我的代码:

新客户.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib uri="http://www.springframework.org/tags/form" prefix="form" %>

<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>Insert title here</title>
</head>
<body>

    <h1>Create New Customer</h1>

    <c:url var="saveUrl" value="/mis/start/newcustomer" />
    <form:form modelAttribute="customerAttribute" method="POST" action="${saveUrl}">
        <table>
            <tr>
                <td><form:label path="customerTargetId">Customer Target ID:</form:label></td>
                <td><form:input path="customerTargetId"/></td>
            </tr>

            <tr>
                <td><form:label path="customerName">Customer Name</form:label></td>
                <td><form:input path="customerName"/></td>
            </tr>

            <tr>
                <td><form:label path="customerCountry">Customer Country</form:label></td>
                <td><form:input path="customerCountry"/></td>
            </tr>
        </table>

        <input type="submit" value="Save" />
    </form:form>

</body>
</html>

启动.jsp

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<h1>Test</h1>


<c:url var="addUrl" value="/mis/start/newcustomer" />
<p><a href="${addUrl}">Create new customer</a></p>
</body>
</html>

客户控制器

package testapp.mis.controller;

@Controller
@RequestMapping("/start")
public class CustomerController {

@Resource(name="customerService")
private CustomerService customerService;

@RequestMapping(value="/newcustomer", method=RequestMethod.GET)
public String getCustomer(Model model) {

    model.addAttribute("customerAttribute", new Customer());

    return "new-customer";
}

@RequestMapping(value="/newcustomer", method=RequestMethod.POST)
public String postCustomer(@ModelAttribute("customerAttribute") Customer customer) {
    customerService.createCustomer(customer);

    return "redirect:/mis/start";
}
}

web.xml

      <?xml version="1.0" encoding="UTF-8"?>
      <web-app id="WebApp_ID" version="2.4" 
     xmlns="http://java.sun.com/xml/ns/j2ee" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
     http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

     <servlet>
     <servlet-name>mis</servlet-name>
     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
     <load-on-startup>1</load-on-startup>
     </servlet>

<servlet-mapping>
<servlet-name>mis</servlet-name>
<url-pattern>/mis/*</url-pattern>
</servlet-mapping>


    </web-app>

例如,当我尝试访问http://localhost/MIS/mis/start 时,它告诉我该页面不存在。(我已经尝试了 localhost/MIS/start、localhost/mis/start/newcustomer 等的所有组合。)

任何人都可以看到问题是什么?

如果您需要我的代码的其他部分来提供帮助,请告诉我。谢谢!

Since I can't comment, I'll have to write my question as an answer (which it might be):

Do you have your spring.xml setup correctly? The controller needs to be picked up as a bean and as I remember, you need to tell Spring which packages to scan.

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:sws="http://www.springframework.org/schema/web-services"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
       http://www.springframework.org/schema/web-services http://www.springframework.org/schema/web-services/web-services-2.0.xsd
       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

    <context:annotation-config />
    <context:component-scan base-package="your.controller.package"/>
</beans>

我最初认为它正在正确构建的假设是错误的,我的 java 文件没有放在正确的文件夹中。这导致 WEB-INF 下的类文件夹,tomcat 期望它们为空。这是正常工作的 ant 构建文件:

<?xml version="1.0"?>

<project name="Test" default="build" basedir=".">

    <!-- Configure the build properties file which contains properties to access the Manager application -->
    <property file="build.properties"/>

    <!-- Configure web directory -->
    <property name="web.dir" value="WebContent"/>


    <!-- Configure the directory into which the web application is built -->
    <property name="build.dir" value="${web.dir}/WEB-INF/classes"/>

    <!-- Configure source directory that contains the java code -->
    <property name="src.dir" value="src"/>


    <!--Configure the context path for the application -->
    <property name="path" value="/test"/>

    <!-- Add all the lib files inside the WebContent/WEB-INF/lib directory as well as the tomcat lib files to the classpath -->
    <path id="master-classpath">
        <fileset dir="${web.dir}/WEB-INF/lib">
            <include name="*.jar"/>
        </fileset>
        <fileset dir="${appserver.lib}">
            <!-- Apache Tomcat lib. ${appserver.lib} comes from the build.properties file -->
            <include name="servlet*.jar"/>
        </fileset>
        <pathelement path="${build.dir}"/>
    </path>

    <!-- Executable Targets -->
    <target name="init" description="Creates build directory">
        <mkdir dir="${build.dir}"/>
    </target>

    <target name="build" depends="init" description="Compiles the java files in the main source tree">
        <javac destdir="${build.dir}" debug="true" srcdir="${src.dir}">
            <classpath refid="master-classpath"/>
        </javac>
    </target>

    <target name="war" depends="build" description="Creates a war file in the tomcat directory">
        <war destfile="${appserver.home}/webapps/${path}.war" webxml="${web.dir}/WEB-INF/web.xml">
            <fileset dir="${web.dir}">
                <include name="**/*.*"/>
            </fileset>
        </war>
    </target>
</project>
