if (excludedPatterns != null && prepare.isUrlExcluded(request, excludedPatterns)) { chain.doFilter(request, response); } else { request = prepare.wrapRequest(request); ActionMapping mapping = prepare.findActionMapping(request,

• 1.Struts2 和 SpringMVC 原理简介• 2.Struts2 和 SpringMVC 共存• 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

DateEditorprivate 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 + "WEB-

INF/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-8859-1DEFAULT_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！ ");}

THANKS FOR LISTENING!
