private JSONObject result;
private IAppService ssuAppService;

public String getApps(){
logger.info("OuterInterfaceAction getApps()..start" );
result = new JSONObject();
try {
List<App> listApp = ssuAppService.getAppList();
if(null==listApp||listApp.size()<1){
result.put("returnCode", "10");
result.put("returnMsg", "app不存在");
return SUCCESS;
}
JsonConfig jsonConfig = new JsonConfig(); //建立配置文件
jsonConfig.setIgnoreDefaultExcludes(false);
jsonConfig.setCycleDetectionStrategy(CycleDetectionStrategy.LENIENT);
jsonConfig.setExcludes(new String[]{"deviceType","className","entityDescription","objectDescription","objectID","objectName"}); //jsconfig 设置过滤属性

result.put("returnCode", "00");
result.put("returnMsg", "认证成功");

result.put("extraInfo", JSONArray.fromObject(listApp, jsonConfig).toString());

//处理编码开始

HttpServletResponse response = ServletActionContext.getResponse();
response.setContentType("text/html;charset=GBK");//转换成你需要接收字符的编码
response.getWriter().write(result.toString());
response.getWriter().flush();

response.getWriter().close();

//转码结束

return SUCCESS;
} catch (Exception e) {
result.put("returnCode", "-1");
result.put("returnMsg", "认证失败，接口发生异常");
e.printStackTrace();
return SUCCESS;
}

}
