一个拦截器拦截一个路径,如果有多个拦截器会按配置先后顺序进行拦截

SpringMVC的拦截器,路径拦截与排除问题
![图片说明](https://img-ask.csdn.net/upload/201903/27/1553683117_587537.png) 需求: 现在我想不拦截/item/这个路径下的大部分url,但是又需要拦截少量的url。 问题: 按道理我这段代码是这个意思,可是没有测试没有拦截我设置的/item/下的少量url。 希望各位前辈看看眼,分享下解决思路和办法。不胜感激!
SpringMVC拦截器跳转会自动在跳转的路径加请求!
首先感谢各位朋友帮忙!! 问题如下: 我使用了拦截器控制登录状态,现在我能够进入拦截器,问题在于我转发到页面的时候,转发路径会在我写的 地址前面+ 请求,变成新的地址 比如,我发的请求是 back/getAll,会自动返回一个新jsp页面的地址 SessionFilter: public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object o) throws Exception { Employee employee = (Employee) request.getSession().getAttribute("employee"); if (null == employee) { // 跳转方式一:(二选一)我两种都试了 response.sendRedirect("WEB-INF/pages/back/login/login.jsp"); //跳转方式二: request.getRequestDispatcher("WEB-INF/pages/back/login/login.jsp").forward(request, response); return false; } else { return true; } } SpringMVC配置文件: <mvc:interceptors> <mvc:interceptor> <mvc:mapping path="/back/**"/><!--我这里有多级请求--> <bean class="sessionFilter.SessionFilter"/> </mvc:interceptor> </mvc:interceptors> 结果页面: ![图片说明](https://img-ask.csdn.net/upload/201704/22/1492849497_82520.png)
springmvc框架,HandlerInterceptor拦截器跳转不了
**需求**:用户session十分钟内无请求就会自动删除。无论用户发送什么请求都要被拦截器拦截,并跳转到登录页面。 **问题**:拦截器能拦截到用户的访问行为,可是,跳转语句五法执行。 **我的代码**: HandlerInteceptor: ``` @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object arg2) throws Exception { HttpSession session = request.getSession(true); // session中获取用户名信息 Object obj = session.getAttribute(Constant.LOGIN_SESSION); System.out.println("session中的数据:---> " + obj); if (obj == null || "".equals(obj.toString())) { String location = "/login.jsp" ; response.sendRedirect(location); return false; } return true; } ``` springmvc.xml拦截器配置: ``` <!-- Session失效拦截 --> <mvc:interceptors> <!-- 定义拦截器 --> <mvc:interceptor> <!-- 匹配的是url路径, 如果不配置或/**,将拦截所有的Controller --> <mvc:mapping path="/**" /> <!-- 不需要拦截的地址 --> <!-- 直接用ip:端口号可以打开登录页 --> <mvc:exclude-mapping path="/" /> <!-- 可以浏览器地址栏输入login.jsp后缀访问登录页 --> <mvc:exclude-mapping path="/login.jsp" /> <!-- 以下为静态资源,不需要过滤 --> <mvc:exclude-mapping path="/App/**" /> <mvc:exclude-mapping path="/common/**" /> <mvc:exclude-mapping path="/css/**" /> <mvc:exclude-mapping path="/image/**" /> <mvc:exclude-mapping path="/js/**" /> <mvc:exclude-mapping path="/jsp/**" /> <mvc:exclude-mapping path="/kindeditor/**" /> <mvc:exclude-mapping path="/lib/**" /> <bean class="com.ryzh0310.interceptor.SystemSessionInterceptor"></bean> </mvc:interceptor> </mvc:interceptors> ``` web.xml中session删除配置(为了测试我写了最小时间1): ``` <!-- 登录退出session控制 --> <session-config> <session-timeout>1</session-timeout> </session-config> ``` 我的项目结构: ![图片说明](https://img-ask.csdn.net/upload/201712/15/1513299471_920782.png) 先谢谢你们啊 你们说我的重定向路径应该写成request.getContextPath() 而不应该直接写成/login.jsp 我打印了日志了,日志内容是: request.getContextPath() = /login.js 请帮我看下是不是其他问题吧。 我用的是springmvc+mybatis 抱歉,我是这么测试的,结果就是上面那行日志内容 ``` System.out.println("request.getContextPath() = " + request.getContextPath() + "/login.jsp"); ``` 先感谢大家了。 我改了改springmvc.xml配置文件, ``` <!-- Session失效拦截 --> <mvc:interceptors> <!-- 定义拦截器 --> <mvc:interceptor> <!-- 匹配的是url路径, 如果不配置或/**,将拦截所有的Controller --> <mvc:mapping path="/**" /> <!-- 不需要拦截的地址 --> <mvc:exclude-mapping path="/login.jsp" /> <mvc:exclude-mapping path="/user/login" /> <mvc:exclude-mapping path="/App" /> <mvc:exclude-mapping path="/common" /> <mvc:exclude-mapping path="/css" /> <mvc:exclude-mapping path="/image" /> <mvc:exclude-mapping path="/js" /> <mvc:exclude-mapping path="/jsp" /> <mvc:exclude-mapping path="/kindeditor" /> <mvc:exclude-mapping path="/lib" /> <bean class="com.ryzh0310.interceptor.SystemSessionInterceptor"></bean> </mvc:interceptor> </mvc:interceptors> ``` mvn:mapping Path由 "/" 改为 "/**" mvc:exclude-mapping path也由 "/file/**"改成了"/file" **现在的情况是:** 1.可以跳转到登录界面了,然而地址栏上显示的是被拦截的请求所请求的目标界面的url。 2.这样跳转来的登陆界面,根本不能登录,可以输入帐号密码,却不能发送登录请求

SpringMvc返回JSON在IE下下载的问题,配好了,一使用拦截器的话在IE下就又成下载了
用的maven+springMVC+spring+mybatis, 搭框架的时候在spring-mvc.xml里配了关于IE的JSON配置,本来是正常的,但是在加了拦截器的配置之后,这个就没有效果了,IE下返回的JSON又成下载文件了。怀疑是通过拦截器的适合 返回的contenttype又变成默认了。不知道 有什么解决办法。 spring用的4.1.7. 这是关于返回JSON的配置,在spring-mvc.xml ``` <!-- 配置SpringMVC @ResponseBody和@RequestBody注解 --> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> <property name="messageConverters"> <list> <ref bean="stringHttpMessageConverter"/> <ref bean="jsonHttpMessageConverter" /> </list> </property> </bean> <!-- JSON Converter 保证 JSON能正常转换 --> <bean id="jsonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>text/html; charset=UTF-8</value> <value>application/json;charset=UTF-8</value> </list> </property> </bean> <!-- String Converter 保证正常输出字符串 --> <bean id="stringHttpMessageConverter" class="org.springframework.http.converter.StringHttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>text/plain;charset=UTF-8</value> <value>apolication/json; charset=UTF-8</value> </list> </property> </bean> ``` 这是拦截器相关配置 在spring-mvc.xml ``` <!-- 启动SpringMVC的注解功能,它会自动注册HandlerMapping、HandlerAdapter、ExceptionResolver的相关实例 <mvc:annotation-driven /> <mvc:default-servlet-handler /> --> <!-- 拦截器配置 <mvc:interceptors> <mvc:interceptor> <mvc:mapping path="/**"/> <bean class="com.rv.core.base.BaseInterceptor"> <property name="allowUrls"> <list> --> <!-- 如果请求中包含以下路径,则不进行拦截 <value>/login</value> <value>/jsp</value> <value>/js</value> <value>/css</value> <value>/image</value> <value>/images</value> </list> </property> </bean> </mvc:interceptor> </mvc:interceptors> --> ```
tomcat项目虚拟路径问题
我想给项目配置一个虚拟路径(images),用于储存图片文件,但是我想在用户访问images 检测权限,就是走一遍项目中的拦截器,我看了网上的一些配置虚拟路径的方法,都可以 直接访问文件,而不会走拦截器,而且都不会经过我的项目,完成从tomcat就直接获取 到了静态资源,请问我要怎么设置才可以让它走拦截器,就是说让这个虚拟路径作为项目 的一个子文件夹,而不是tomcat管理的文件夹。我用的是springmvc框架!
springmvc中的重复提交问题
如图:下面是网络中找到的方法,测试下来发现几个问题,请大神们帮忙下,谢谢。 原理:自定义拦截器,在打开页面和保存页面时添加注解方式来验证重复提交。 问题1:因为都是token,所以当同一台电脑打开2个不同路径页面时,陆续保存会报错。 问题2:当2台电脑用同一用户打开相同路径的页面时,保存时并没有验证重复,导致重复提交了。 原因我知道为什么,现怎么解决这2个问题呢,谢谢,给个思路。 ![图片说明](https://img-ask.csdn.net/upload/201807/12/1531365546_924451.png)
springMVC上传图片,可能是我选的路径不对还是啥,在客户端读取存入数据库的路径时,图片不显示。
不知道什么回事,图片就是读不出来,但是看网页源代码,有图片路径,单独访问图片路径也可以读到图片,但是在jsp中读不到,可能是过滤器或者拦截器的原因,不知道了,问问各位大神。 下面时spring MVC上传代码: ``` String path = null; //将当前上下文初始化给 CommonsMutipartResolver (多部分解析器) CommonsMultipartResolver multipartResolver=new CommonsMultipartResolver( request.getSession().getServletContext()); //检查form中是否有enctype="multipart/form-data" if(multipartResolver.isMultipart(request)) { //将request变成多部分request MultipartHttpServletRequest multiRequest=(MultipartHttpServletRequest)request; //获取multiRequest 中所有的文件名 Iterator iter=multiRequest.getFileNames(); while(iter.hasNext()) { //一次遍历所有文件 MultipartFile file=multiRequest.getFile(iter.next().toString()); if(file!=null) { path=request.getServletContext().getRealPath("")+"\\image\\"+file.getOriginalFilename(); //上传 file.transferTo(new File(path)); } } } ``` 存入数据库的路径是这样:D:\Tomcat\apache-tomcat-7.0.42\webapps\students\image\QQ图片20180531181825.jpg,在jsp页面中图片路径就是这个,但是就是显示不出来,请问该怎么修改才能在将图片在jsp页面中显示出来,还有, 我这个是不是没有将图片存到服务器上啊? 求教各位了,谢谢

@RequestMapping(params = "executeSearch") @Transactional public String executeSearch(HttpServletRequest request) { //测试事物控制。 infoService.test(); return "info/search"; } ServiceImpl.java public void test(){ try { infoDAO.test(); } catch (Exception e) { e.printStackTrace(); } } Service.java @Transactional public void test(); DaoImpl.java @Transactional public void test() { try { String sql = "update operation_log set username='1' where id='1'"; List<Object> condition = new ArrayList<Object>(); this.executeUpdateBySql(sql, condition); String sql1 = "update operation_log set username=33, where id='1'"; this.executeUpdateBySql(sql1, condition); } catch (RuntimeException e) { e.printStackTrace(); } } DaoImpl.java继承HibernateDao HibernateDao.java /***************注入***********/ @Resource private SessionFactory sessionFactory; public SessionFactory getSessionFactory() { return sessionFactory; } public void setSessionFactory(SessionFactory sessionFactory) { this.sessionFactory = sessionFactory; } public Session getSession() { //事务配置后,可通过getCurrentSession方法获得session return sessionFactory.getCurrentSession(); } public int executeUpdateBySql(final String sql,final List<Object> conditions){ try { Query query = getSession().createSQLQuery(sql); if(conditions!=null && conditions.size()>0){ for(int i=0;i<conditions.size();i++){ if(conditions.get(i)!=null && !conditions.get(i).equals("")){ query.setParameter(i, conditions.get(i)); } } } return query.executeUpdate(); } catch (RuntimeException e) { throw e; }finally{ System.out.println(getSessionFactory().getCurrentSession().beginTransaction().isActive()); } } 整体代码是这样的,在运行daoImpl.java中test()方法的时候执行第一条SQL时会提交事物,直接修改数据库中的值,执行第二条SQL时会报错,理论上应该都不提交事物。但实际上第一条执行了之后就提交事物了,不知道是我框架问题还是我写的问题,求大神帮忙指出问题所在。万分感谢! ```
Java学习的正确打开方式

程序员接私活怎样防止做完了不给钱?
首先跟大家说明一点,我们做 IT 类的外包开发,是非标品开发,所以很有可能在开发过程中会有这样那样的需求修改,而这种需求修改很容易造成扯皮,进而影响到费用支付,甚至出现做完了项目收不到钱的情况。 那么,怎么保证自己的薪酬安全呢? 我们在开工前,一定要做好一些证据方面的准备(也就是“讨薪”的理论依据),这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发...
