public void getEntityTypes() {
List<TagEntityType> json = tagEntityTypeService.getEntityTypes();
renderJson(json);
}
单步跟踪json的值如下，
[com.ai.ctos.bdi.module.tagentitytype.TagEntityType@8aa3b4cd {id:1, edit_at:null, create_at:2016-07-12 09:22:29.0, type_name:信用, remarks:信用产品类}]
然后执行renderJson(json);的时候，控制台显示查询语句n次：
Sql: select * from tag_entity_type order by id limit 10
然后，一直抛异常：

请教下@JFinal是什么引起的错误，这是第二次遇到。
跟踪异常抛出位置：
com.fasterxml.jackson.databind.ObjectMapper的2980行：
_configAndWriteValue(_jsonFactory.createGenerator(sw), value);
当前的value值为：
[com.ai.ctos.bdi.module.tagentitytype.TagEntityType@8aa3b4cd {id:1, edit_at:null, create_at:2016-07-12 09:22:29.0, type_name:信用, remarks:信用产品类}]
