大家好，又见面了，我是你们的朋友全栈君。
1.需要库：
commons-beanutils-1.7.0.jar
commons-collections-3.1.jar
commons-lang-2.1.jar
commons-logging-1.1.3.jar
ezmorph-1.0.2.jar
json-lib-2.4-jdk15.jar
2.转换方法：
//对象转json
sqlModel model = new sqlModel();
model.setAge(18);
model.setHeight(188.0);
model.setName("张三");
String jsonStr = null;
try {
JSONObject jsonObject = JSONObject.fromObject(model);
jsonStr = jsonObject.toString();
System.out.println(jsonStr);
} catch (Exception e) {
System.out.println("数组转json失败");
}
结果：{"age":18,"height":188,"name":"张三"}
//数组转json
String jsonStr = null;
try {
JSONArray jsonObject = JSONArray.fromObject(myNameList);
jsonStr = jsonObject.toString();
System.out.println(jsonStr);
} catch (Exception e) {
System.out.println("数组转json失败");
}
结果：["aaaa","bbbb","cccc","cc","zzl","zzl","zzl","zzl","zzl","zzl","zzl","zzl","zzl","zzl","zzl","zzl","zzl","zzl"]参考地址 https://www.cnblogs.com/z-z-z/p/6839356.html
