Question

我正在构建一个使用Spring MVC和AngularJS的简单应用程序。问题是表单的值即将到来null。

代码在上面。

MockController.java

@Controller
public class MockController {

    private Logger log = LoggerFactory.getLogger(MockController.class);

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

      @RequestMapping(value = "/SubmitMock", method = RequestMethod.POST)
        public @ResponseBody String getMock(@RequestBody MockForm mockForm){ 

          StringBuilder reponseData = new StringBuilder();
            reponseData.append("Name1: "+ mockForm.getName1()+" ");
            reponseData.append("Name2: "+ mockForm.getName2()+" ");
            reponseData.append("Name3: "+ mockForm.getName3());

            log.debug(reponseData.toString());

            return reponseData.toString();

        }
    }

MockForm.java

public class MockForm {

private String name1;
private String name2;
private String name3;

public String getName1() {
    return name1;
}
public void setName1(String name1) {
    this.name1 = name1;
}
public String getName2() {
    return name2;
}
public void setName2(String name2) {
    this.name2 = name2;
}
public String getName3() {
    return name3;
}
public void setName3(String name3) {
    this.name3 = name3;
}

}

    </div>

</body>
</html>

问题是我在Submit点击mock.jsp mockForm.getName1(), mockForm.getName2() and mockForm.getName3() Null。{/ p>

有什么想法吗？

谢谢

您的帖子应该发送mockForm参数填充formData，因为您的服务器方法要求mockForm具有您已经包含在formData中的各种类对象网址应为'/Mock/SubmitMock'，而不是http://localhost:8080/fire-fatca-web/SubmitMock.html

<强>代码

$http.post('/Mock/SubmitMock', { 
    mockForm: formData
})

使用AngularJS和Spring MVC的表单值为Null
