java - 从 java 中的大型 JSON 文件中提取特定文本(密码字符串)，而不使用 JSON 帮助器类

Question

我有以下从特定 REST 调用收到的大型 JSON。我只想提取密码字符串(以粗体突出显示)。所以我需要值(value)观。java中的ConfigPWD_USER.password、ConfigPWD_ROOT.password、instanceOwnerPassword、databaseUserPassword、fencedUserPassword 。我想我必须使用字符串正则表达式进行搜索。有人可以帮忙吗？

在 groovy 中，有内置 groovy.json.JsonSlurper ，查找其中一个值的代码可能如下所示:

def json = new groovy.json.JsonSlurper().parseText('''
{
    "deployment_name": "name1",
    "model": {
        "model": {
            "description": "",
            "nodes": [{
                "id": "OS Node",
                "ptype": "image:OS Node",
                "attributes": {
                    "ConfigPWD_USER.password": "1<xor>NzozMzA=",
                    "ConfigPWD_ROOT.password": "1<xor>NzozMzA="
                },
                "type": "image:OS",
                "groups": {},
                "locked": []
            }, {
                "id": "disk for db instance",
                "attributes": {
                    "ConfigPWD_USER.password": "2<xor>NzozMzA=",
                    "ConfigPWD_ROOT.password": "2<xor>NzozMzA="
                },
                "type": "add disk:1.0.0",
                "groups": {},
                "locked": []
            }]
        }
    }    
}            
''')

json.model.model.nodes.collect{n-> n.attributes."ConfigPWD_USER.password" }
