Question

我在网上搜索并找到了一些解决方案，但我仍面临同样的问题。

我正在尝试创建一个Web应用程序，将Angularjs作为前端弹簧支撑作为后端。我能够通过$ http.post方法访问url资源，但是数据与pojo的绑定不会发生。值始终为空。

Web.xml中：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-  app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee   http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
<display-name>login</display-name>
<servlet>
    <servlet-name>springws</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>springws</servlet-name>
    <url-pattern>/rest/*</url-pattern>
</servlet-mapping>
<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>

我的调度程序servlet配置

Angualrjs控制器文件

login.controller('RegisterController',['$scope','userFactory', function($scope, userFactory) {

$scope.user;

$scope.saveUser = function(){
    userFactory.saveUser($scope.user);
};
}]);

Angularjs factory js file

angular.module('login')
.factory('userFactory' , ['$http', function($http){

var userFactory= {};

userFactory.authenticate = function(user){
    console.log(user.name);
    console.log(user.password);
};

userFactory.saveUser = function(user){
    console.log(user.name);
    console.log(user.password);
    console.log(user.phone);
    console.log(user.email);
     $http.post('rest/register', user).success(console.log("registered"));
};

userFactory.forgotPassword = function(user){
    console.log(user.name);
};

return userFactory;
}]);

Jsp页面调用userFactory.saveUser（）函数，该函数又调用我的休息服务，

我的控制器类

@Controller
public class UserController {

@RequestMapping(value = "/authenticate", method = RequestMethod.GET)
public  @ResponseBody String getState(UserData ud) {
    System.out.println(ud.getPassword());
    return "true";
}

@RequestMapping(value = "/register", method = RequestMethod.POST)
public  @ResponseBody String registerUser(Users ud) {
    System.out.println(ud.getPassword());
    return "true";
}
}

println语句始终打印为空。

谁能告诉我哪里出错了？

在论证之前，您需要@RequestBody和getState方法中的registerUser。此外，getState必须是POST方法。

@Controller
public class UserController {

@RequestMapping(value = "/authenticate", method = RequestMethod.POST)
public  @ResponseBody String getState(@RequestBody UserData ud) {
    System.out.println(ud.getPassword());
    return "true";
}

@RequestMapping(value = "/register", method = RequestMethod.POST)
public  @ResponseBody String registerUser(@RequestBody Users ud) {
    System.out.println(ud.getPassword());
    return "true";
}
}

Angularjs $ http.post数据不与后端pojo绑定
