JsonConfig过滤对象属性
转载自：http://blog.csdn.net/java20100406/article/details/6232055
通过配置JsonConfig过滤有可能引起循环的字段,如果不这样，根据hibernate的原则会不断的级联查询.
*************************************Action******************************************************
1.对象。
JsonConfig jsonConfig = new JsonConfig();
jsonConfig.setExcludes( new String[]{ "creator", "module", "testPoints","testProcesses","highLevelRequirements","lowLevelRequirements"} );
String result = JSONObject.fromObject( testCase对象 ,jsonConfig).toString();
2.List数组
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对象
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对象 ).toString();
