1.先编写jsonConfig的初始化代码
private JsonConfig jsonConfig;
public action构造方法() {
jsonConfig = new JsonConfig();
jsonConfig.registerJsonValueProcessor(Date.class, newJsonValueProcessor() {
private SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-ddHH:mm:ss");
@Override
public Object processObjectValue(String key,Object value, JsonConfig jsonConfig) {
return this.process(value);
}
@Override
public Object processArrayValue(Object value,JsonConfig arg1) {
return this.process(value);
}
// 处理Date类型返回的Json数值
private Object process(Object value) {
if (value == null) {
return "";
} else if (value instanceof Date)
return sdf.format((Date)value);
else {
return value.toString();
}
}
});
// 不该传给前台的字段
jsonConfig.setJsonPropertyFilter(new PropertyFilter() {
public boolean apply(Objectsource, String name, Object value) {
if (source instanceof RaffleLog) {
if ("contact".equals(name)) {
return true;
}
}
return false;
}
});
}
/**
* @param response
* @param returnType
* @throws IOException
*/
private voidprintReturnType2Response(HttpServletResponse response, ReturnType<?>returnType) throws IOException {
response.setCharacterEncoding("UTF-8");
response.setContentType("application/json;charset=utf-8");
response.getWriter().print(JSONObject.fromObject(returnType, jsonConfig));
}
2.再在须要跳转的action方法中编写对应的返回代码
ReturnType<Map<String,Integer>> returnType = newReturnType<Map<String, Integer>>();
if(条件){
returnType.setStatus(ReturnType.Status.SUCCESS.getValue());
}else{
returnType.setStatus(ReturnType.Status.FAIL.getValue());
}
returnType.setMsg(sb.toString());
this.printReturnType2Response(response,returnType);
3.一个案例分析：

private finalInteger pageSize = 15; // 每页显示页数
Logger logger= Logger.getLogger(DocInfoCustomAction.class);
privateJsonConfig jsonConfig;

jsonConfig = new JsonConfig();
jsonConfig.registerJsonValueProcessor(Date.class,new JsonValueProcessor() {
private SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-ddHH:mm:ss");
@Override
