hutool json转xml

首先将hutools整合进springboot项目中。

https://hutool.cn/docs/#/
详细的可以参考这个文档

在pom文件中引入

<dependency> <groupId>cn.hutool</groupId> <artifactId>hutool-all</artifactId> <version>5.0.5</version> </dependency>

hutools中包含了三个工具类，分别是JSON工具-JSONUtil、JSON对象-JSONObject、JSON数组-JSONArray

1.将Javabean对象转换未json对象（对于map，string之类的对象操作方法与之类似）
实体类对象

@Datapublic class ActivityLog { private String id; private String name; private String activityPoint; private String activityDescription;}

2.转换为JSON并修改其中数据

@Test public void test(){ ActivityLog activityLog = new ActivityLog(); activityLog.setId("123"); activityLog.setName("听说明天有台风"); activityLog.setActivityDescription("Here's an operation"); activityLog.setActivityPoint("1"); JSON json = JSONUtil.parse(activityLog); System.out.println(json); json.putByPath("name","tingshuomingtianyoutaifeng"); System.out.println(json); }

执行结果

{"name":"听说明天有台风","activityPoint":"1","id":"123","activityDescription":"Here's an operation"}{"name":"tingshuomingtianyoutaifeng","activityPoint":"1","id":"123","activityDescription":"Here's an operation"}

可能很多人觉着我这样写很鸡肋，这样是没啥必要的一种操作，但是相信我，时间久了总会出现一种情景是必须要你这样实现的，不信我可以给你看看我写这篇博客时真挚的眼神。

3.接下来我们还可以将转换后的json重新转换为Javabean

@Test public void test(){ ActivityLog activityLog = new ActivityLog(); activityLog.setId("123"); activityLog.setName("听说明天有台风"); activityLog.setActivityDescription("Here's an operation"); activityLog.setActivityPoint("1"); JSON json = JSONUtil.parse(activityLog); System.out.println(json); json.putByPath("name","tingshuomingtianyoutaifeng"); System.out.println(json); //将json转换为Javabean String jsons= json.toString(); activityLog = JSONUtil.toBean(jsons,ActivityLog.class); System.out.println(activityLog); }

执行结果

{"name":"听说明天有台风","activityPoint":"1","id":"123","activityDescription":"Here's an operation"}{"name":"tingshuomingtianyoutaifeng","activityPoint":"1","id":"123","activityDescription":"Here's an operation"}ActivityLog(id=123, name=tingshuomingtianyoutaifeng, activityPoint=1, activityDescription=Here's an operation)
