java - 如何将多个参数从一个 View 传递到另一个 View (Spring MVC)

Question

将这些参数从一个 jsp 页面传递到另一个 jsp 页面的最佳方法是什么？

第一个处理程序方法:

@RequestMapping(value="/search", method = RequestMethod.POST)
public String postSearchStudent(
                    @RequestParam(value = "program.programId") String programId,
                    @RequestParam(value = "rollNumber") String rollNumber,
                    @RequestParam(value = "rollYear") String rollYear,
                    @RequestParam(value = "indexNumber") String indexNumber,
                    Model model) {

    // do something ???

    // Call StudentService to do the searching
    Student student = studentService.search(indexNumber);

    // if student isn't in the db load addStudent.jsp, else load student.jsp
    if (student == null)
        return "addStudent";
    else
        return "student";
}

searchStudent.jsp:

<c:url var="searchUrl" value="/essays/main/student/search" />
<form:form modelAttribute="student" method="POST" action="${searchUrl}">

第二个处理程序方法:

@RequestMapping(value="/add", method = RequestMethod.GET)
public String getAddStudent(
                    @RequestParam(value = "program.programId") String programId,
                    @RequestParam(value = "rollNumber") String rollNumber,
                    @RequestParam(value = "rollYear") String rollYear,
                    @RequestParam(value = "indexNumber") String indexNumber,
                    Model model) {

        Student student = new Student();
        student.setRollNumber(rollNumber);
        student.setRollYear(rollYear);
        student.setIndexNumber(indexNumber);
        Program program = programService.get(programId);
        student.setProgram(program);
        model.addAttribute("student", student);

        return "addStudent";
}

addStudent.jsp:

<c:url var="saveUrl" value="/essays/main/student/add" />
<form:form commandName="student" method="POST" action="${saveUrl}">

谁能告诉我如何将这 4 个参数(programId、rollNumber、rollYear、indexNumber)从 searchStudent.jsp 传递到 addStudent.jsp？

为什么不将这些保存在 cookie 中？使用类似 jquery cookie 插件之类的东西？或者将这些参数作为属性添加到模型对象并将模型传递给 View ，或者如果您使用的是 Spring 3.2，请查看类似 @ControllerAdvice 的内容。有很多选择。
