将对象转换为JSON字符串-蒲公英云

将对象转换为JSON字符串

一引包

<dependency>
   <groupId>com.alibaba</groupId>
   <artifactId>fastjson</artifactId>
   <version>1.2.31</version>
</dependency>

二测试方法——将对象转化为JSON字符串

@Test
public 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<DiffObjectAssoRuleSet> 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<DiffObjectUpdateRuleSet> 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);
}

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)
