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：
/** * * @Title:DocInfoCustomAction.java * @Copyright:Copyright (c) 2005 * @Description:* @Created on 2014-4-16 上午9:22:25 * @author 杨凯 */public class DocInfoCustomAction extends DispatchAction{ private finalInteger pageSize = 15; // 每页显示页数 Logger logger= Logger.getLogger(DocInfoCustomAction.class); privateJsonConfig jsonConfig; publicDocInfoCustomAction() { jsonConfig = new JsonConfig(); jsonConfig.registerJsonValueProcessor(Date.class,new JsonValueProcessor() { private SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-ddHH:mm:ss"); @Override public Object processObjectValue(String key, Object value, JsonConfigjsonConfig) { 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(Object source, String name, Object value) { if (source instanceof RaffleLog) { if ("contact".equals(name)) { return true; } } return false; } }); } /** * @paramresponse * @paramreturnType * @throwsIOException */ 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)); } /** * 批量删除操作 * * @parammapping * @paramform * @paramrequest * @paramresponse * @return * @throwsIOException * @throwsAppException */ publicActionForward delete(ActionMapping mapping, ActionForm form, HttpServletRequestrequest, HttpServletResponse response) throws IOException, AppException { Stringids = Tool.getDefaultValue(request, "ids", ""); // 获取下拉列表的值 StringBuffer sb = new StringBuffer(); ReturnType
