前端特殊字符数据，后端接收产生错乱，前后端都需要处理

前端：

const data = {createTime: "2024-06-11 09:58:59",id: "1800346960914579456",merchantId: "1793930010750218240",mode: "DEPOSIT",channelCode: "if(amount >= 50){'iugu2pay';} else if(amount < 10){'iugupay';} else {'todaypay';}",settleRate: 8,settleFee: 8,conditionSettleRate: "if(amount >= 5){ 0.2;} else{0.88;}",name: "HaliAntpay"
};// Encode the fields
data.channelCode = encodeURIComponent(data.channelCode);
data.conditionSettleRate = encodeURIComponent(data.conditionSettleRate);// Send the encoded data
fetch('http://your-backend-endpoint/yourEndpoint', {method: 'POST',headers: {'Content-Type': 'application/json'},body: JSON.stringify(data)
})
.then(response => response.json())
.then(result => console.log(result))
.catch(error => console.error('Error:', error));

后端：

import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;
