调查问卷动态生成的一点探索

jquery json spring restful mango db ajax

之前做过企业内部用的调查问卷系统,因为每一年的调查内容都有差异,所以每次都要重新修改代码,所以想到了能否用程序做一个自动问卷生成系统.

大体的思路如下:

1>一套基于web的后台问卷生成系统,通过web页面录入具体的调查问卷(问题,答案,单选还是多选,还是文字回答等等),生成的问卷以json的方式ajax提交给后台系统,后台可以利用spring rest的方式接收request,然后将json串存入mango db

2>调查参与者根据收到的url,访问调查问卷系统(后台返回json串,前端负责显示具体的调查页面),参与具体的调查,并提交调查结果,同样也是通过json串向后台发起rest请求,然后后台将json串存入mango db

试验性代码如下

App.java

package prd.survey;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * Hello world!
 *
 */
@SpringBootApplication
public class App 
{
    public static void main( String[] args )
    {
    	SpringApplication.run(App.class, args);
    }
}

SurveyController.java

package prd.survey;

import java.util.concurrent.atomic.AtomicLong;

import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class SurveyController {

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

    @RequestMapping(value="/greeting", method = RequestMethod.POST,consumes = "application/json")
    public Greeting greeting(@RequestBody String body) {
    	System.out.println("body:" + body);
        return new Greeting(counter.incrementAndGet(),
                            String.format(template, "John"));
    }
}

Greeting.java

package prd.survey;

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;
    }
}

页面效果如下:
