使用postman问题 404错误

我第一次用postman测接口
url:http://localhost:8080/hhv2/interface/getMyRolls
输入:{
"head": {

"deviceId":"deviceId",
"os":1,
"token":"",

},
"body":{

"rows": "10",
"page":"10",
"type":"1",
}
}
然后send 就报404错误是哪错了?

.code { border: 1px solid #ccc; background: #efefef; font-size: 16px; } .propNS { color: #660E7A } .propTag { color: #000080 } .propName { color: #0000ff; } .propValue{ color: #008000 }
404 error!请求地址有误!
