  11. 1.Struts2和SpringMVC原理简介 • 2.Struts2和SpringMVC共存 • 3.Spring修改内容

  12. 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）

  13. 2、404问题 throw new ResourceNotFoundException("ResumePositionController edit parameter id is error. id: " + id);

  14. 3、@InitBinder问题

  15. 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) : ""); }

  16. 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;

  17. @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");

  18. 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); }

  19. private static final DataBind<Resume> RESUME_DATA_BIND = DataBindManager.getInstance().getDataBind(DataBindTypeEnum.RESUME); RESUME_DATA_BIND.put(resume); RESUME_DATA_BIND.get()

  20. 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！"); }

  21. Thanks for Listening!
