在groovy中有内置和代码来查找其中一个值，可能是这样的：groovy.json.JsonSlurperdef json = new groovy.json.JsonSlurper().parseText('''{&nbsp; &nbsp; "deployment_name": "name1",&nbsp; &nbsp; "model": {&nbsp; &nbsp; &nbsp; &nbsp; "model": {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "description": "",&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "nodes": [{&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "id": "OS Node",&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "ptype": "image:OS Node",&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "attributes": {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "ConfigPWD_USER.password": "1<xor>NzozMzA=",&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "ConfigPWD_ROOT.password": "1<xor>NzozMzA="&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; },&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "type": "image:OS",&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "groups": {},&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "locked": []&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }, {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "id": "disk for db instance",&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "attributes": {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "ConfigPWD_USER.password": "2<xor>NzozMzA=",&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "ConfigPWD_ROOT.password": "2<xor>NzozMzA="&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; },&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "type": "add disk:1.0.0",&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "groups": {},&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "locked": []&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }]&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; }&nbsp; &nbsp;&nbsp;}&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;''')json.model.model.nodes.collect{n-> n.attributes."ConfigPWD_USER.password" }
