配置JsonConfig過濾有可能引起循環的字段

通過配置JsonConfig過濾有可能引起循環的字段,如果不這樣，根據hibernate的原則會不斷的級聯查詢.

*************************************Action******************************************************

1.對象。

JsonConfig jsonConfig = new JsonConfig();

jsonConfig.setExcludes( new String[]{ "creator", "module", "testPoints","testProcesses","highLevelRequirements","lowLevelRequirements"} );

String result = JSONObject.fromObject( testCase對象 ,jsonConfig).toString();

2.List數組

JsonConfig jsonConfig = new JsonConfig();

jsonConfig.setExcludes( new String[]{ "creator", "module", "testPoints","testProcesses","highLevelRequirements","lowLevelRequirements"} );

JSONArray lineitemArray = JSONArray.fromObject( testCases集合List ,jsonConfig);

String result = JSONArray.fromObject(lineitemArray).toString();

3.Map對象

Map map = new HashMap();

JsonConfig jsonConfig = new JsonConfig();

jsonConfig.setExcludes( new String[]{ "creator", "module", "testPoints","testProcesses","highLevelRequirements","lowLevelRequirements"} );

JSONArray lineitemArray = JSONArray.fromObject( testCases集合List ,jsonConfig);

map.put("testCases", lineitemArray);

String result = JSONObject.fromObject( map對象 ).toString();

1.對象。

  $.ajax({

3.Map對象
