问题描述
我正在尝试使用两个对象数组和“ join”将json转换为json文件，这是输入文件：
{
"Employee": [
{
"id": "emp_1","firstName": "Jose","lastName": "Perez","ssn": "ssn1","depId": "dep_1"
},{
"id": "emp_2","firstName": "Antonio","lastName": "Ramirez","ssn": "ssn2","depId": "dep_2"
}
],"Department": [
{
"id": "dep_1","description": "Instituto nacional de investigaciones nucleares (ININ)","division": "Research"
},{
"id": "dep_2","description": "Instituto Mexicano de Seguro Social (imsS)","division": "Healthcare"
},{
"id": "dep_3","description": "Comision Nacional Bancaria y de Valores (CNBV)","division": "Financial"
}
]
}
这是预期的输出：
{
"Employee": [
{
"id": "emp_1","lasttName": "Perez","department": "Instituto nacional de investigaciones nucleares (ININ)","lasttName": "Ramirez","department": "Instituto Mexicano de Seguro Social (imsS)","division": "Healthcare"
}
]
}
我一直在尝试做，但是没有被映射，我在做什么错？ 这是我的规格：
[
{
"operation": "shift","spec": {
"Department": {
"*": {
"@" : "Department.@id"
}
},"Employee" : "Employee"
}
},{
"operation": "shift","spec": {
"Employee": {
"*": {
"depId" : {
"*" : {
"@2" : {
"Department" : {
"&4" : "test"
}
}
}
}
}
}
}
}
]
请我已经花了很多时间来尝试解决它，有没有人知道如何使用Jolt来解决它：https://github.com/bazaarvoice/jolt？
解决方法
检查此规范，使部门中的ID更易于访问，然后比较值，
[
{
"operation": "shift","spec": {
"Employee": "Employee",//make the dep id easier to compare
"Department": {
"*": {
"@": "Department.@(0,id)"
}
}
}
},{
"operation": "shift","spec": {
"Employee": {
"*": {
"depId": {
"*": {
"@(4,Department)": {
// Compare values and move everything into the employee object
"@3": "Employee.&","@(&)": "Employee.&.department"
}
}
}
}
}
}
},"spec": {
"Employee": {
"*": {
"@": "Employee[]"
}
}
}
},{
// Object cleansing
"operation": "shift","spec": {
"Employee": {
"*": {
"id": "Employee[].id","firstName": "Employee[&1].firstName","lastName": "Employee[&1].lastName","ssn": "Employee[&1].ssn","department": {
"description": "Employee[&2].department","division": "Employee[&2].division"
}
}
}
}
}
]
非常感谢您的答复@Jagadesh 我或多或少地遵循了您的相同方法，但做了一些小的修改：
[
{
"operation": "shift","Department": {
"*": {
"@": "Department.@id"
}
}
}
},Department)": {
"@(&)": {
"@(0,description)": "Employee[&5].department","@(0,division)": "Employee[&5].division"
}
}
}
},"@": "Employee[&]"
}
}
}
},// just to remove depId from Employee
{
"operation": "remove","spec": {
"Employee": {
"*": {
"depId": ""
}
}
}
}
]
