Cordys BOP 4平台开发实战——MongoDB提供文档服务(1)
1、查询返回单个文档JSON数据
(1)查询返回独立文档
MongoDB语法:
.find({"ID":"2015040011"})
Soap请求:
<SOAP:Envelope xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/"><SOAP:Body>
<FindDocuments xmlns="http://schemas.cordys.com/XiaoywWSAppServerPackage" preserveSpace="no" qAccess="0" qValues="">
<collectionName>BusinessEntity</collectionName>
<querycondition>{"ID":"2015040011"}</querycondition>
</FindDocuments>
</SOAP:Body>
</SOAP:Envelope>
返回值截取内容如下:
<findDocuments>
{ "_id" : { "$oid" : "5525d9e084ae4890fc58c489"} , "ID" : "2015040011" , "Name" : "高级采购流程" , "Dept" : "经营管理部"}</findDocuments>
(2)查询返回嵌套文档
MongoDB语法:
.find({"ID":"2015040013"})
Soap请求:
<SOAP:Envelope xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP:Body>
<FindDocuments xmlns="http://schemas.cordys.com/XiaoywWSAppServerPackage" preserveSpace="no" qAccess="0" qValues="">
<collectionName>BusinessEntity</collectionName>
<querycondition>{"ID":"2015040013"}</querycondition>
</FindDocuments>
</SOAP:Body>
</SOAP:Envelope>
嵌套文档查询结果截取主要内容如下:
<findDocuments>
{ "_id" : { "$oid" : "55260ce084ae4cb2fa2e2bea"} , "ID" : "2015040013" , "Name" : "新版合作伙伴采购流程" , "Dept" : "经营管理部" , "DETAIL" :
[ { "WF" : "01" , "WFNAME" : "启动"} , { "WF" : "02" , "WFNAME" : "结束"}]}
</findDocuments>
2、扩展文档,返回文档系统级的_id
(1)插入单文档操作
MongoDB语法:
.save({"ID":"2015040012","Name":"新版外包采购流程","Dept":"经营管理部"})
Soap请求:
<SOAP:Envelope xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP:Body>
<GetExpandDocument xmlns="http://schemas.cordys.com/XiaoywWSAppServerPackage" preserveSpace="no" qAccess="0" qValues="">
<collectionName>BusinessEntity</collectionName>
<JSONString>{"ID":"2015040012","Name":"新版外包采购流程","Dept":"经营管理部"}</JSONString>
</GetExpandDocument>
</SOAP:Body>
</SOAP:Envelope>
返回_id值如下:
<getExpandDocument>5525e34d84ae4cb2fa2e2be6</getExpandDocument>
(2)插入嵌套文档(相当于一对多关系)
MongoDB语法:
.save({ID:‘2015040013‘,Name:‘新版合作伙伴采购流程‘,Dept:‘经营管理部‘,DETAIL:[{WF:‘01‘,WFNAME:‘启动‘},{WF:‘02‘,WFNAME:‘结束‘}]})
Soap请求:
<GetExpandDocument xmlns="http://schemas.cordys.com/XiaoywWSAppServerPackage" preserveSpace="no" qAccess="0" qValues="">
<collectionName>BusinessEntity</collectionName>
<JSONString>{ID:‘2015040013‘,Name:‘新版合作伙伴采购流程‘,Dept:‘经营管理部‘,DETAIL:[{WF:‘01‘,WFNAME:‘启动‘},{WF:‘02‘,WFNAME:‘结束‘}]}</JSONString>
</GetExpandDocument>
(3)修改数据,在_id值不变的情况下,执行修改操作
MongoDB语法:
.save({"_id":{"$oid":"5525d9e084ae4890fc58c489"},"ID":"2015040011","Name":"经领导外包采购流程","Dept":"经营管理部"})
Soap请求:
<GetExpandDocument xmlns="http://schemas.cordys.com/XiaoywWSAppServerPackage" preserveSpace="no" qAccess="0" qValues="">
<collectionName>BusinessEntity</collectionName>
<JSONString>{"_id":{"$oid":"5525d9e084ae4890fc58c489"},"ID":"2015040011","Name":"经领导外包采购流程","Dept":"经营管理部"}
</JSONString>
</GetExpandDocument>
