Question

HTTP状态406 –不可接受根据请求中接收到的主动协商标头字段，目标资源没有用户代理可接受的当前表示形式，并且服务器不愿意提供默认表示形式。

控制器代码

@RequestMapping(value="/welcomes", method = RequestMethod.GET, produces="application/json")
    public @ResponseBody List<UserBean> welcome(@ModelAttribute UserBean userBean, HttpServletResponse response)
    {
        List<UserBean> usernames=new ArrayList<UserBean>();
        usernames = retrievedataservice.findAllUsers(userBean);
        System.out.println(usernames.size());
        return usernames;
    }

角度js代码

   <script>
    var app = angular.module('myApp', []);
    app.controller('UserController', function($scope, $http, $location){
        $scope.usernames=[];
            var url = $location.absUrl() + "welcomes";
            $http.get(url).then(function (response) 
            {
                $scope.usernames = response.records;
            },function error(response) 
            {
                $scope.postResultMessage = "Error with status: " +  response.statusText;
            });
    });
    </script>
<table border="1" width="50%" height="50%"> 
    <tr><th>user_name</th><th>phone</th><th>email</th></tr>
     <tr data-ng-repeat="user in usernames">
     <td>{{user.username}}</td>
      <td>{{user.phone}}</td>
       <td>{{user.email}}</td>
       </tr>   
   </table>

如何将数据从spring控制器发送到angular js控制器？

Answer 1

尝试如下更改方法签名。

@RequestMapping(value="/welcomes", method = RequestMethod.GET,produces={"application/json"})
    public @ResponseBody List<UserBean> welcome(UserBean userBean, HttpServletResponse response)

请注意，我删除了@ModelAttribute并更改了产品。

还要确保您的类路径中有杰克逊或任何其他json库。

如果没有，则在下面添加到pom.xml

<!-- add jackson to support restful API, otherwise the API will return 406 error -->
    <dependency>
        <groupId>org.codehaus.jackson</groupId>
        <artifactId>jackson-mapper-asl</artifactId>
        <version>1.9.13</version>
    </dependency>
