JsonObject jsonObject=new JsonObject();
jsonObject.add("returnVlue", policyForViewBean.toJsonElement());
GsonBuilder builder=new GsonBuilder();
String returnVlue=builder.create().toJson(jsonObject);
//request.setAttribute("returnVlue", returnVlue);
PrintWriter out = null;
try {
out = response.getWriter();
out.print(returnVlue);
log.debug(returnVlue);
} catch (Exception e) {
log.error("获取Writer错误!", e);
throw new CommonException(ErrorConstants.SERVICE_ERROR, ErrorConstants.S_INTEGRATION_ERROR, "系统错误!");
} finally {
if (out != null) {
out.flush();
out.close();
}
}



var returnVlue= eval('(' +returnVlue + ')').returnVlue;



结果为returnVlue
