Question

我需要处理json响应，它是通过休息服务GET方法调用来实现的。我已经看过这些链接的解决方案： -

http://www.journaldev.com/2315/java-json-processing-api-example-tutorial

http://answers.oreilly.com/topic/257-how-to-parse-json-in-java/

但它不符合我的要求，因为它小而且静态。我在下面保留我的json响应： -

`<!--json response start -->

所以我在这里得到基于我的休息网址调用的动态响应，所以如何将这个json响应设置为我的pojo。

任何帮助将不胜感激。

提前谢谢你。 `

Answer 1

您可以使用框架来处理所有这些;一个伟大的是春天。看看here 这是stackoverflow question让你快速入门。

上面的链接示例：

创建一个Controller来处理REST调用（更改为演示json使用）：

@Controller
@RequestMapping("/kfc/brands")
public class JSONController {

    @RequestMapping(value="{name}", method = RequestMethod.POST)
    public @ResponseBody Shop getShopInJSON(@PathVariable String name, @RequestBody JsonNode json) {
        // do stuff with the json request body (its is jackson)
        JsonNode test= json.get("test");

        Shop shop = new Shop();
        shop.setName(name);
        shop.setStaffName(new String[]{"mkyong1", "mkyong2"});

        return shop;

    }
}

// you could use jQuery to perform a REST call to your new controller:
$.ajax({
    type: "POST",
    url: "[your server]/kfc/brands",
    data: {"test": "json value"},
    success: function() {}
});

Answer 2

尝试gson lib。它将 json 转换为 pojo ，将 pojo 转换为 json 。

Answer 3

如果您有JSON响应的架构，那么jsonschema2pojo将是一个很好的工具。它的工作方式类似于JAXB为XML所做的工作，因为它在构建时基于模式生成pojos，然后您可以在编译时使用它。

如果没有架构但您对格式有信心，则可以始终generate the schema yourself。
