java实体类转json对象（Java中的对象转JSON和JSON转对象）
java实体类转json对象（Java中的对象转JSON和JSON转对象）
先说结论吧： 使用阿里的fastjson包 就可以很方便的相互转换。pom引入

下面是具体的例子：
- 实体类ReqCheckAccount继承ReqMain ReqMain中只有几个通用的属性。下面直接贴ReqCheckAccount类
public class ReqCheckaccount extends ReqMain {
private String account = "";//账户
private String accountName = "";//账户户名
public String getAccount() {
return account;
}
public void setAccount(String account) {
this.account = account;
}
public String getAccountName() {
return accountName;
}
public void setAccountName(String accountName) {
this.accountName = accountName;
}
@Override
public String toString() {
return "ReqCheckAccount{"
"account='" account '\''
" accountName='" accountName '\''
" id='" id '\''
" appId='" appId '\''
" bankId='" bankId '\''
" jgxybh='" jgxybh '\''
'}';
}
}
- 测试类
@Test
public void testJSON(){
ReqCheckAccount reqCheckAccount = new ReqCheckAccount();
String strJson = JSONObject.toJSONString(reqCheckAccount);
System.out.println("Object to JSON test:" strJson);
strJson = "{\"account\":\"111\" \"accountName\":\"222\" \"appId\":\"333\" \"bankId\":\"444\" \"id\":\"555\" \"jgxybh\":\"666\"}";
ReqCheckAccount reqObj = (ReqCheckAccount) JSONObject.toJavaObject(JSON.parseObject(strJson) ReqCheckAccount.class);
System.out.println("JSON to Object:" reqObj.toString());
}
- 结果
输出结果
