Question

我遇到的问题是ModelAndView无法找到JSP视图

以下是控制器

@Controller
public class BasicController {
    private String GUID;

    @RequestMapping(value = "/basicLti.spr", method = RequestMethod.GET)
    public ModelAndView view(@RequestParam(value = ORG_IDS_ATTRIBUTE, required = false) String orgIds) {
        ModelAndView mav = new ModelAndView();

        String GUID="one";

        if(orgIds != null) {
            mav =  new ModelAndView("sso-auth-tool");
            mav.addObject(userId, "36bdf294-2832-4179-b9e4-b4e2148fb048");
            mav.addObject(GUID,"String");
            mav.addObject(ORG_IDS_ATTRIBUTE, "512488b9-a387-45b0-b7c6-d514d112566e");
            return mav;
        }
        System.out.println("here i am");
    }

}

我有以下jsp视图：

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<html>
<head>
</head>
<body>
    <!--[if IE]>
    <form name="formLogin" action="${ssoUrl}" method="post" target="_blank">
    <p id="message" style="visibility:hidden;">Your Starrmatica course has been opened in a new window.</p>
<![endif]-->
    <!--[if !IE]>-->

    <p>Got Message</p>


        <input type='hidden' name='iqity_id' value='${user_id}'>
        <input type="hidden" name="school_id" value="${school_id}">
        <input type="submit" name="guid_key" value="${guid_key}">
        <!-- <input type="submit" id="sas-auth-tool" value="Authenticate Resources" name="submit" /> -->
    </form>
</body>
</html>

servlet-context.xml文件

<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <beans:property name="prefix" value="/WEB-INF/views/" />
        <beans:property name="suffix" value=".jsp" />
    </beans:bean>

现在它没有找到asso.jsp - HTTP 404错误！我的问题是; 我如何评估jsp文件？

Answer 1

ModelAndView mav = new ModelAndView("sso-auth-tool");

    String GUID="one";

    if(orgIds != null) {
        mav.addObject(userId, "36bdf294-2832-4179-b9e4-b4e2148fb048");
        mav.addObject(GUID,"String");
        mav.addObject(ORG_IDS_ATTRIBUTE, "512488b9-a387-45b0-b7c6-d514d112566e");
        return mav;
    }
    System.out.println("here i am");

这应该有效，因为必须有一个视图名称，但在您的代码中，视图名称仅在orgIds != null不相反的情况下设置。
