如何将JSON发送到Struts2使用AngularJS形式操作？

我的代码：

我在struts.xml

<package name="default" extends="json-default"> 

    <interceptors> 
     <interceptor-stack name="defaultStack"> 
      <interceptor-ref name="json"> 
       <param name="enableSMD">true</param> 
      </interceptor-ref> 
     </interceptor-stack> 
    </interceptors> 

    <default-interceptor-ref name="defaultStack" /> 

    <action name="angularAction" class="actions.CustomerAction" method="findCustomer" > 
     <result type="json"> 
       <param name="root">customer</param> 
       <param name="excludeNullProperties">true</param> 
       <param name="noCache">true</param> 
     </result> 
    </action> 

</package> 

我的Java类：

public class Customer { 

    private String id; 
    private String name; 
    private String email; 
    private String phone; 

    public Customer() { 

    } 

    public Customer(String id, String name, String email, String phone) { 

     this.id = id; 
     this.name = name; 
     this.email = email; 
     this.phone = phone; 

    } 

    //getters and setters omitted 
} 

我Struts2的行动

public class ClienteAction extends ActionSupport { 

    private List<Customer> jsonCustomer; 

    public List<Customer> getJsonCustomer() { 
     return jsonCustomer; 
    } 


    public void setJsonCustomer(List<Customer> jsonCustomer) { 
     this.jsonCustomer = jsonCustomer; 
    } 

    public String findCustomer() { 

     List<Customer> jc = getJsonCustomer(); 

     return SUCCESS; 

    } 

} 

我的角度代码：

angular.module('myApp', []); 

angular.module('myApp'). 
controller('MyController', function ($scope, $http) { 
    $scope.getDataFromServer = function(customer) { 

     var data1 = JSON.stringify(customer); 

      $http({ 
       url: 'angularAction?jasonCustomer=' + data1, 
       method: 'GET' 
      }).then (function successCallback(response) { 
       $scope.customer = response.data;      

      }, function errorCallback(response) { 
       console.log(response.data) ; 
      })  

     }; 
    }); 

My Libs

它不工作！ angularAction中的变量jsonCustomer为null。

我是有角的新手。我正在使用这个教程，但角而不是jQuery。

所有你需要在你的angularJS改变，在这里首先是如下的变化：

angular.module('myApp', []); 

angular.module('myApp'). 
controller('MyController', function ($scope, $http) { 
    $scope.getDataFromServer = function(customer) { 

     var data1 = JSON.stringify(customer); 

      $http({ 
       url: 'angularAction', 
       method: 'POST', 
       'jasonCustomer' : data1 
      }).then (function successCallback(response) { 
       $scope.customer = response.data;      

      }, function errorCallback(response) { 
       console.log(response.data) ; 
      })  

     }; 
    }); 

现在用参数jasonCustomer，最后我们得到我们的行动JSON数据angularAction GET JSON数据类：

import java.io.IOException; 
import java.util.ArrayList; 
import java.util.HashMap; 
import java.util.List; 
import java.util.Map; 

import javax.servlet.http.HttpServletRequest; 

import org.apache.commons.io.IOUtils; 
import org.apache.struts2.ServletActionContext; 

import com.blogspot.geekonjava.db.ProductDB; 
import com.blogspot.geekonjava.gs.Product; 
import com.opensymphony.xwork2.Action; 

public class CustomerAction{ 
static HttpServletRequest request ; 


    public static String findCustomer() 
    { 
    try { 
    request = ServletActionContext.getRequest(); 
    String filename = IOUtils.toString(request.getInputStream()); 
    System.out.println("jsonData "+filename); 
    // Here you can use your code 



    } catch (IOException e) { 
    // TODO Auto-generated catch block 
    e.printStackTrace(); 
    } 
    return "success"; 
    } 



    public String execute() { 
    return Action.SUCCESS; 
     } 

}
