if (excludedPatterns != null

• 3.Spring修改内容
1、 <mvc:annotation-driven/>
<mvc:annotation-driven/>会自动注册DefaultAnnotationHandlerMapping
与AnnotationMethodHandlerAdapter两个bean,是spring MVC为
@Controllers分发请求所必须的
并提供了：数据绑定支持，@NumberFormatannotation支持，
@DateTimeFormat支持，@Valid支持，读写XML的支持（JAXB），读
写JSON的支持（Jackson）
2、404问题
throw new ResourceNotFoundException("ResumePositionController edit
parameter id is error. id: " + id);
3、@InitBinder问题
DateEditor
private static final DateFormat DATEFORMAT = new SimpleDateFormat("yyyy-MM-dd")
private static final DateFormat TIMEFORMAT = new SimpleDateFormat("yyyy-MM-dd
HH:mm:ss");
private DateFormat dateFormat;
private boolean allowEmpty = false;
public String getAsText() {
Date value = (Date) getValue();
DateFormat dateFormat = this.dateFormat;
if (dateFormat == null)
dateFormat = DATEFORMAT;
return (value != null ? dateFormat.format(value) : "");
}
4、 Ajax提交问题
Map<String, Object> dataMap = new HashMap<String, Object>();
dataMap.put("resume", resume);
String webRoot = ServletUtil.getWebRoot();
if (StringUtil.isNotEmpty(webRoot) && !webRoot.endsWith("/")) {
webRoot += "/";
}
String content = "";
try {
content = TemplateUtil.parseTemplate4EscapeHtml(webRoot + "WEBINF/ftl/resume/", "frag_practice.ftl", dataMap, true);
} catch (Exception e) {
log.error("preview parseTemplate Error:" + modelType);
}
return content;
@ResponseBody中文乱码问题
StringHttpMessageConverter中设置的默认编码为ISO-8859-1
DEFAULT_CHARSET = Charset.forName("ISO-8859-1");
5、 DataBindManager问题
public boolean preHandle(HttpServletRequest request, HttpServletResponse
response, Object handler) throws Exception {
Resume resume = resumeService.getResumeByUid(userBase.getUid());
request.setAttribute("resume",resume);
return super.preHandle(request, response, handler);
}
@RequestMapping(value = "index")
public ModelAndView index(HttpServletRequest request) {
Resume resume = getUserResume();
return new ModelAndView("resume/index", "resume", resume);
}
private static final DataBind<Resume> RESUME_DATA_BIND =
DataBindManager.getInstance().getDataBind(DataBindTypeEnum.RESUME);
RESUME_DATA_BIND.put(resume);
RESUME_DATA_BIND.get()
6、validator
@Autowired
@Qualifier("resumePracticeValidator")
private ResumePracticeValidator resumePracticeValidator;
final BindException errors = new BindException(practice, "practice");
resumePracticeValidator.validate(practice, errors);
if (errors.hasErrors()) {
return AjaxModel.failed("数据有问题！");
}
