Question

我是angularjs的新手，请帮助。

如何为我的代码获取java rest服务。我使用mockup json数据。

var orderVariable = angular.module('ordermodule',[]);

orderVariable.controller('formController',['$scope', '$state', function($scope, $state) {

    $scope.processForm = function() {
        alert('awesome!');  
    };

    $scope.formData = {};

}]);

orderVariable.factory('orderableItemsService', function() {

    var orderableItemsService = {

你可以使用Spring来做到这一点。

基本上，您可以执行以下操作：

创建一个spring项目并创建一个文件（例如Greeting.java）

package hello;

public class Greeting {

    private final long id;
    private final String content;

    public Greeting(long id, String content) {
        this.id = id;
        this.content = content;
    }

    public long getId() {
        return id;
    }

    public String getContent() {
        return content;
    }
}

使用@RestController获取所需的数据

package hello;

import java.util.concurrent.atomic.AtomicLong;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class GreetingController {

    private static final String template = "Hello, %s!";
    private final AtomicLong counter = new AtomicLong();

    @RequestMapping("/greeting")
    public Greeting greeting(@RequestParam(value="name", defaultValue="World") String name) {
        return new Greeting(counter.incrementAndGet(),
                            String.format(template, name));
    }
}

并使用

运行应用

package hello;

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.SpringApplication;
import org.springframework.context.annotation.ComponentScan;

@ComponentScan
@EnableAutoConfiguration
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

nog在角度控制器中获取日期如下：

function Hello($scope, $http) {
    $http.get('http://rest-service.guides.spring.io/greeting').
        success(function(data) {
            $scope.greeting = data;
        });
}

使用正确的地址替换rest-service.guides.spring.io。
