需要在groovy中用恒定字符串替换JSON字段的帮助

Question

我想替换一个JSON领域-Json Strings

[{"RoleName": "Normal User","ModuleName": "Calendar Management"},
 {"RoleName": "Reporter","ModuleName": "Incident Management"},
 {"RoleName": "Viewer","ModuleName": "ESG"},
 {"RoleName": "Viewer","ModuleName": "Apps"}]

源json json hody {“ personInformation”：{“ emailAddress”：“ ” ，“名称”：{“ firstName”：“ fabian”，“ lastname”：“ koehlmann”，“ preferredname”：“fabiankã¶hlmann”}，address“：{” adversionLine1“：” berllin gmbh“ “：”eRasmusstraã²20,,,,，“邮政编码”：“ 10553”}，“员工信息”：{“ losplyepy型”：“内部”，“ homploymentStatus”：“ active”，“ active”，“ jobrole”，“ jobrole”：{“decr疑：“财务 - it”，“ isCreateDepartment”：“ null”，“ jobtitle”：“专家IT安全＆amp; Infrastructure”，“ susterisorid”：“ null”，“ startdate”：“ 09/29/2021”，“ “：“ null”}，“位置”：“柏林GmbH”，“职业”：“ null”}，“ Isuser”：“ true”，“ userInformation”：{“ userId”：“ 7FA1785F-F4F4F3-42B5-96BD -33F195521635“，“状态”：“活动”，“位置”：{“ scope”：“ trn-loc”，“角色”，“ jsontoreplace”}}，“ recorduid”：“ 2022/05/27”，“ id“：” A0201412“}}}

groovy脚本

def Message processData(Message message) {
   def body = message.getBody(java.lang.String) as String;
   def jsonSlurper = new JsonSlurper()      
   def SourceBody = jsonSlurper.parseText(body)
   def ReplaceData = jsonSlurper.parseText('[{"RoleName": "Normal User","ModuleName": 
          "Calendar Management"},{"RoleName": "Reporter","ModuleName": "Incident Management"}, 
              {"RoleName": "Viewer","ModuleName": "ESG"},{"RoleName": "Viewer","ModuleName": 
              "Apps"}]')
   body = body.replaceAll('JSONtoReplace','ReplaceData');
   message.setBody(body);
   return message;
}

我想替换JSON字段

您可以做这样的事情：

import groovy.json.JsonBuilder
import groovy.json.JsonSlurper

// ...

// This hardcoded String represents "body" from the code in the question
String jsonString = '''
[{"RoleName": "Normal User","ModuleName": "Calendar Management"},
{"RoleName": "Reporter","ModuleName": "Incident Management"}]
'''
def slurper = new JsonSlurper()
def json = slurper.parseText(jsonString)

println 'Before Update...'
println new JsonBuilder(json).toPrettyString()

json[0].'RoleName' = 'Updated'

println 'After Update...'
println new JsonBuilder(json).toPrettyString()

输出：

Before Update...
[
    {
        "RoleName": "Normal User",
        "ModuleName": "Calendar Management"
    },
    {
        "RoleName": "Reporter",
        "ModuleName": "Incident Management"
    }
]
After Update...
[
    {
        "RoleName": "Updated",
        "ModuleName": "Calendar Management"
    },
    {
        "RoleName": "Reporter",
        "ModuleName": "Incident Management"
    }
]
