1、创建json文件（demo.json）

{ 
    	"button": [
    		{ 
    			"type": "click",
    			"name": "今日歌曲",
    			"key": "V1001_TODAY_MUSIC"
    		},
    		{ 
    			"name": "菜单",
    			"sub_button": [
    				{ 
    					"type": "view",
    					"name": "搜索",
    					"url": "http://www.soso.com/"
    				},
    				{ 
    					"type": "miniprogram",
    					"name": "wxa",
    					"url": "http://mp.weixin.qq.com",
    					"appid": "wx286b93c14bbf93aa",
    					"pagepath": "pages/lunar/index"
    				},
    				{ 
    					"type": "click",
    					"name": "赞一下我们",
    					"key": "V1001_GOOD"
    				}
    			]
    		}
    	]
    }

2、在pom.xml中添加依赖包

<dependency>
    			<groupId>com.alibaba</groupId>
    			<artifactId>fastjson</artifactId>
    			<version>1.2.54</version>
    		</dependency>
    		<dependency>
    			<groupId>org.apache.commons</groupId>
    			<artifactId>commons-io</artifactId>
    			<version>1.3.2</version>
    		</dependency>

3、创建测试类（FileDemo3.java）

package com.jeff.demo;
    
    import java.io.InputStream;
    
    import org.apache.commons.io.IOUtils;
    
    import com.alibaba.fastjson.JSONObject;
    
    public class FileDemo3 { 
    
    	public static JSONObject fileToJson(String fileName) { 
    		JSONObject json = null;
    		try (
    			InputStream is = Thread.currentThread().getContextClassLoader().getResourceAsStream(fileName);
    		) { 
    			json = JSONObject.parseObject(IOUtils.toString(is, "utf-8"));
    		} catch (Exception e) { 
    			System.out.println(fileName + "文件读取异常" + e);
    		}
    		return json;
    	}
    
    	public static void main(String[] args) { 
    		String fileName = "doc/demo.json";
    		JSONObject json = FileDemo3.fileToJson(fileName);
    		System.out.println(json);
    	}
    
    }

4、控制台输出结果
