Spring boot 实现json和jsonp格式数据接口

1.新建一个类继承AbstractJsonpResponseBodyAdvice，重写父类构造方法，
传入callback和jsonp参数。

package com.alibaba.sinfo.h5.agent.advice;

import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.servlet.mvc.method.annotation.AbstractJsonpResponseBodyAdvice;

/**
 * Created by Jack on 2017/5/31.
 */
@ControllerAdvice
public class JsonpAdvice extends AbstractJsonpResponseBodyAdvice {
    public JsonpAdvice() {
        super("callback", "jsonp");
    }
}

2.写返回json和jsonp格式数据的Controller

package com.alibaba.sinfo.h5.agent.controller

import com.alibaba.fastjson.JSONObject
import org.springframework.web.bind.annotation.GetMapping
import org.springframework.web.bind.annotation.RestController

import java.text.SimpleDateFormat

/**
 * Created by jack on 2017/5/19.
 */
@RestController
class HelloWorld {
    @GetMapping("/hello")
    def helloWorld(){
        JSONObject object = new JSONObject()
        object.put("time", new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()))
        object
    }
}

3. 测试输出

//http://localhost:8500/hello
{
time: "2017-05-31 22:04:50"
}

// 20170531220604
// http://localhost:8500/hello?callback=hellojsonp

/**/hellojsonp({
"time": "2017-05-31 22:06:03"
});
