Java 弹簧丢失上下文路径,java,spring,jsp,Java,Spring,Jsp,我有一个简单的控制器，它必须将我的表单保存在DB中。我尝试在这个控制器中映射命令“/tests/review/saveChanges”，但当我按下“save”按钮时，我得到了“HTTP状态400–错误请求” 我的控制器： @Controller @RequestMapping(value = "/tests") public class TestController { private TestInterfaceService testService; @Autowire

我有一个简单的控制器，它必须将我的表单保存在DB中。我尝试在这个控制器中映射命令“/tests/review/saveChanges”，但当我按下“save”按钮时，我得到了“HTTP状态400–错误请求”

我的控制器：

@Controller
@RequestMapping(value = "/tests")
public class TestController {

private TestInterfaceService testService;

@Autowired(required = true)
@Qualifier(value = "testService")
public void setTestService(TestInterfaceService testService) {
    this.testService = testService;
}

//here we get list objects
@RequestMapping(value = "/list", method = RequestMethod.GET)
public String listTests(Model model) {

    model.addAttribute("test", new Test());
    model.addAttribute("listTests", this.testService.listTests());
    return "proposals";
}

@RequestMapping(value = "/add", method = RequestMethod.POST)
public String addTest(Test t) {
    if (t.getId() == 0) {
        this.testService.addTest(t);
    } else {
        // existing person, call update
        this.testService.updateTest(t);
    }
    return "redirect:/tests/list";
}

@RequestMapping(value = "/remove/{id}")
public String removeTest(@PathVariable("id") long id) {
    this.testService.removeTest(id);
    return "redirect:/tests/list";
}

//Here we start work with specific object
@RequestMapping("/review/{id}")
public String editTest(@PathVariable("id") long id, Model model) {
    Test test = this.testService.getFullTestById(id);
    model.addAttribute("candidateTest", test);
    model.addAttribute("candidateQuestions", test.getQuestions());

    model.addAttribute("candidateAnswers", test.getQuestions());
    return "review";
}

//Here I'm try save all changes
@ModelAttribute("candidateTest")
@RequestMapping(value = "/review/saveChanges", method = RequestMethod.POST)
public String review(@PathVariable("candidateTest") Test candidateTest, Model model) {
    testService.addTest(candidateTest);
    return "redirect:/tests/list";
}

@RequestMapping(value = "/choise/{id}/{status}", method = RequestMethod.GET)
public String choise(@PathVariable("id") long id, @PathVariable("status") String status, Model model) {
    Test test = this.testService.getTestById(id);
    test.setStatus(TestStatus.Developing.getStatus(status));
    this.testService.updateTest(test);
    model.addAttribute("test", this.testService.getTestById(id));
    model.addAttribute("questions", this.testService.getListQuestionsById(id));
    return editTest(id, model);
}

@RequestMapping(value = "/previewTest/{id}")
public String previewTest(@PathVariable("id") long id, Model model) {
    Test test = this.testService.getTestById(id);
    model.addAttribute("ourTest", test);
    return "previewTest";
}
}

虽然很久以前有人问过

而不是 
${contextPath}/tests/review/saveChanges

试一试

让我知道它是否有效

URL有什么问题吗？你应该发布web.xml和spring配置文件Done，但不是舒尔it can Useful，你还不知道吗？
