二 测试方法——将对象转化为JSON字符串

@Testpublic void objectToJSON(){   // 前端的请求   ReqDiffObjRuleSet reqDiffObjRuleSet = new ReqDiffObjRuleSet();   // 设置前端请求中的简单变量   reqDiffObjRuleSet.setObjectName("电视");   reqDiffObjRuleSet.setPipeLineId("1");   reqDiffObjRuleSet.setProductFamilyid("1");   reqDiffObjRuleSet.setRelationObjName("网线");   // 前端请求中的复杂变量   DiffObjRuleSet diffObjRuleSet = new DiffObjRuleSet();   // 封装复杂变量的对象   RelationObject relationObject = new RelationObject();   relationObject.setCompareResultRule(1);   relationObject.setInvalidDataMode(1);   relationObject.setMulDataMode(1);   relationObject.setPipelineId("1");   relationObject.setProductFamilyId("1");   relationObject.setRelationObjectName("a");   relationObject.setRelationType(1);   relationObject.setUpdateRule(1);   // 封装复杂变量的第1个列表   List
   
     diffObjectAssoRuleSetList = new ArrayList<>();   DiffObjectAssoRuleSet diffObjectAssoRuleSet = new DiffObjectAssoRuleSet();   diffObjectAssoRuleSet.setAssoObjectCompareMode(1);   diffObjectAssoRuleSet.setPipelineId("1");   diffObjectAssoRuleSet.setPriority(1);   diffObjectAssoRuleSet.setProductFamilyId("1");   diffObjectAssoRuleSet.setAssoObjectCompareFieldName("a");   diffObjectAssoRuleSet.setAssoObjectName("a");   diffObjectAssoRuleSet.setSourceAttributeName("a");   diffObjectAssoRuleSet.setSourceObjectName("a");   diffObjectAssoRuleSet.setRuleName("test");   diffObjectAssoRuleSetList.add(diffObjectAssoRuleSet);   // 封装复杂变量的第2个列表   List
    
      diffObjectUpdateRuleSetList = new ArrayList<>();   DiffObjectUpdateRuleSet diffObjectUpdateRuleSet = new DiffObjectUpdateRuleSet();   diffObjectUpdateRuleSet.setPipelineId("1");   diffObjectUpdateRuleSet.setProductFamilyId("1");   diffObjectUpdateRuleSet.setInputAttributeName("a");   diffObjectUpdateRuleSet.setInputObjectName("a");   diffObjectUpdateRuleSet.setTargetAttributeName("a");   diffObjectUpdateRuleSet.setTargetObjectName("a");   diffObjectUpdateRuleSetList.add(diffObjectUpdateRuleSet);   // 复杂变量中的对象和列表设置   diffObjRuleSet.setRelationObject(relationObject);   diffObjRuleSet.setDiffObjectUpdateRuleSetList(diffObjectUpdateRuleSetList);   diffObjRuleSet.setDiffObjectAssoRuleSetList(diffObjectAssoRuleSetList);   // 设置前端请求中的复杂变量   reqDiffObjRuleSet.setDiffObjRuleSet(diffObjRuleSet);   // 对象转字符串   String s= JSON.toJSONString(reqDiffObjRuleSet);   System.out.println(s);}
    
   

三 运行结果如下

{"diffObjRuleSet":{"diffObjectAssoRuleSetList":[{"assoObjectCompareFieldName":"a","assoObjectCompareMode":1,"assoObjectName":"a","pipelineId":"1","priority":1,"productFamilyId":"1","ruleName":"test","sourceAttributeName":"a","sourceObjectName":"a"}],"diffObjectUpdateRuleSetList":[{"inputAttributeName":"a","inputObjectName":"a","pipelineId":"1","productFamilyId":"1","targetAttributeName":"a","targetObjectName":"a"}],"relationObject":{"compareResultRule":1,"invalidDataMode":1,"mulDataMode":1,"pipelineId":"1","productFamilyId":"1","relationObjectName":"a","relationType":1,"updateRule":1}},"objectName":"电视","pipeLineId":"1","productFamilyid":"1","relationObjName":"网线"}

四 将上面结果转化为标准格式

五 控制器

@PostMapping("/conf")public void diffObjAssoObjConf(@RequestBody ReqDiffObjRuleSet reqDiffObjRuleSet){    Result result = new Result();    System.out.println(reqDiffObjRuleSet);}

六 PostMan测试

七 控制台打印

ReqDiffObjRuleSet(diffObjRuleSet=DiffObjRuleSet(relationObject=RelationObject(relationObjectCode=null, relationObjectName=a, relationRuleName=null, relationType=1, compareResultRule=1, mulDataMode=1, invalidDataMode=1, updateRule=1, comparisonGroup=null, pipelineId=1, objectCode=null, productFamilyId=1), diffObjectAssoRuleSetList=[DiffObjectAssoRuleSet(ruleId=null, ruleCode=null, ruleName=test, sourceObjectCode=null, sourceObjectName=a, sourceAttributeCode=null, sourceAttributeName=a, assoObjectCode=null, assoObjectName=a, assoObjectCompareFieldCode=null, assoObjectCompareFieldName=a, assoObjectCompareMode=1, priority=1, pipelineId=1, productFamilyId=1)], diffObjectUpdateRuleSetList=[DiffObjectUpdateRuleSet(ruleId=null, ruleCode=null, ruleName=null, targetObjectCode=null, targetObjectName=a, targetAttributeCode=null, targetAttributeName=a, inputObjectCode=null, inputObjectName=a, inputAttributeCode=null, inputAttributeName=a, pipelineId=1, productFamilyId=1)]), pipeLineId=1, productFamilyid=1, objectName=电视, relationObjName=网线)
