一个spring mvc项目，异常信息直接输出到页面上，而控制台日志里面却没有打印异常堆栈信息? 如下图，错误的堆栈信息都输出到了页面上  而控制台的日志里面却不打印 附上web.xml ``` <?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"> <!-- The definition of the Root Spring Container shared by all Servlets and Filters --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:META-INF/spring/spring-config.xml</param-value> </context-param> <context-param> <param-name>webAppRootKey</param-name> <param-value>manage-web.all.root</param-value> </context-param> <!-- Processes application requests --> <servlet> <servlet-name>springMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:META-INF/spring/springMVC-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springMVC</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!-- Creates the Spring Container shared by all Servlets and Filters --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app> ```

通过freemarker跳转到springmvc某个controller，如果是get方式则没什么问题。如果是post，这里表单制定的是post方式，controller制定的也是post，但是跳转不过去。并且报403错误 “HTTP Status 403 - Bad or missing token!”。求大神帮忙解决。感谢

 如图所示，就一直卡在这，也没有任何报错信息，有大神知道是怎么回事吗，tomcat版本是7.0.94，jdk版本1.8

  一张是运行情况的图，一张是tomcat配置的图，把项目加载到tomcat中了，但是始终跑的是空猫，0.5秒tomcat就运行好了，访问项目就是404。。。求解啊，该怎么解决这个问题呢

整合Spring+SpringMVC+Hibernate时，启动正常，可以打开登录页面，但是进行登录时，无法进入controller层，而且不报错，只输出三行日志。 DispatcherServlet with name 'springMVC' processing POST request for [/SSH/user/login.do] No mapping found for HTTP request with URI [/SSH/user/login.do] in DispatcherServlet with name 'springMVC' Successfully completed request 意思大概是找不到路径，但应该不是路径的问题，如果路径有问题，页面上message会显示有问题的路径，而不是什么都没有。 HTTP Status 404 - type Status report message description The requested resource is not available.

web工程下的某一个目录中有5个文件,其中有两个.svg文件, .woff .ttf .eot 文件各一个. 在tomcat服务器中,这5个文件可以正常访问. 将工程放入jetty容器中, 只能访问.svg文件, 访问另外三个文件则报错404, 错误日志是: No media type found for ServletContextresource [/fonts/inmoon.eot] returning 404

项目启动时不报错，就是无法访问  访问的时候服务器也没有日志，我打的是war包，详情看代码 POM.XML ``` <dependency> <groupId>org.apache.tomcat</groupId> <artifactId>tomcat-servlet-api</artifactId> <version>8.0.39</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <!-- 去除内嵌tomcat--> <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> </exclusion> </exclusions> </dependency> ``` ``` @EnableTransactionManagement @SpringBootApplication @MapperScan("com.vrqzd.dao") public class VrqzdApplication extends SpringBootServletInitializer implements CommandLineRunner { private final static Logger logger = LoggerFactory.getLogger(VrqzdApplication.class); public static void main(String[] args) { SpringApplication.run(VrqzdApplication.class, args); } @Override public void run(String... args) throws Exception { logger.info("主程序启动----------------->>启动完毕"); } } ``` ``` @EnableTransactionManagement @SpringBootApplication @MapperScan("com.vrqzd.dao") public class SpringBootStartApplication extends SpringBootServletInitializer { @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) { // 注意这里要指向原先用main方法执行的Application启动类 return builder.sources(VrqzdApplication.class); } } ``` ``` /** * 登录页面载入 * @param response * @return */ @RequestMapping(value ="login",method = RequestMethod.GET) public String login(HttpServletResponse response, HttpSession session, HttpServletRequest request){ // return "page/login"; logger.info("==============登录发起=========="); Authentication auth = SecurityContextHolder.getContext().getAuthentication(); if (session.getAttribute("ret")!=null){ request.setAttribute("ret", session.getAttribute("ret")); session.removeAttribute("ret"); } if(auth instanceof AnonymousAuthenticationToken){ return "page/login"; }else{ return "redirect:/user"; } } ``` 发起这个登录的时候后台没有任何日志，就给我一个该网页无法正常运作，

最近使用spring mvc，有一个疑惑。别人调我的接口，新建一个资源，需要传一系列参数，一些参数是用来判断我新建资源方式的。这些参数放在url上是否更加合适，按照我的理解，post请求的话，body里面存放的是新建的资源内容，而用来做判断的参数放在url上。这样的理解不知道合不合理，希望大神解惑。

使用的spring mvc+hibernate框架，logback记录日志的时候，如果出了错误，没有用try。。catch捕捉并logger.error打印的话，能自动打印吗？我记得以前用log4j的话是可以的，现在我系统中出了错误，控制台也没错误信息，日志里面也没有，要是在Controller层的方法上都加上try..catch的话就麻烦了。。 有解决方案吗？ 下面是我logback.xml配置： [code="xml"] <?xml version="1.0" encoding="UTF-8"?> <configuration> <property name="log.sh4frame" value="../logs/sh4frame" /> <jmxConfigurator /> <appender name="stdout" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>%-4relative [%thread] %-5level %logger{35} - %msg %n</pattern> </encoder> </appender> <!-- 按照每天生成日志文件 --> <appender name="logfile" class="ch.qos.logback.core.rolling.RollingFileAppender"> <File>${log.sh4frame}.log</File> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <FileNamePattern>${log.sh4frame}.%d{yyyy-MM-dd}.log.zip</FileNamePattern> <!--日志保存天数--> <maxHistory>100</maxHistory> </rollingPolicy> <encoder> <pattern>%relative [%thread] %level %logger - %msg%n</pattern> </encoder> <!--日志文件最大的大小 默认就是10M--> <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy"> <MaxFileSize>10MB</MaxFileSize> </triggeringPolicy> </appender> <!--日志异步到数据库 --> <logger name="org.hibernate.type.descriptor.sql.BasicBinder" level="INFO" /> <logger name="org.hibernate.type.descriptor.sql.BasicExtractor" level="INFO"/> <logger name="org.hibernate.SQL" level="INFO" /> <logger name="org.hibernate.engine.QueryParameters" level="INFO" /> <logger name="org.hibernate.engine.query.HQLQueryPlan" level="INFO" /> <root level="INFO"> <appender-ref ref="stdout" /> <appender-ref ref="logfile" /> </root> </configuration> [/code]

先看出错提示 TOMCAT没有日志输出，直接在浏览器报的404 拦截器类方法： public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception { LoginAccount user=(LoginAccount) request.getSession().getAttribute("user"); String url=request.getRequestURL().toString(); System.out.println("进入拦截器，请求地址:"+url); if(user==null){ response.sendRedirect("index.jsp"); return false; }else{ return true; } } ``` 拦截器配置 <mvc:view-controller path="/" view-name="index"/> <mvc:interceptors> <mvc:interceptor> <mvc:mapping path="/**"/> <mvc:mapping path="/"/> <mvc:exclude-mapping path="/login.do"/> <mvc:exclude-mapping path="/logout.do"/> <mvc:exclude-mapping path="/room.do"/> <bean id="loginInterceptor" class="com.jszy.oa.intercepter.LoginInterceptor"> <property name="loginUrl" value="login.do"></property> </bean> </mvc:interceptor> </mvc:interceptors> ``` WEB.XML 配置，<url-pattern>节点参考http://iammr.7.blog.163.com/blog/static/49102699201222643458216/文章，拦截根目录。在用户SESSION未超时访问根目录时跳转到后台首页 <servlet> <servlet-name>spring-mvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <description>spring MVC 配置文件</description> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mvc-websocket.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>spring-mvc</servlet-name> <url-pattern></url-pattern> </servlet-mapping> ``` ``` 出问题的地方就在访问http://localhost:8080/oa/，点击登录时请求http://localhost:8080/oa/login.do报了404，没有输出日志。 如果把<url-pattern></url-pattern>改成<url-pattern>*.do</url-pattern> 拦截器能正常工作，就是没有办法拦截这个地址http://localhost:8080/oa/

服务器部署的一个springboot的服务，今天突然出现了一个问题，现象是： 1.当在服务器使用curl 来请求任意的一个接口，第一次请求时可以获得返回值。 2.再次curl任意的接口，服务端没有任何返回，一段时间之后报超时，也不打印任何日志。 3.取消之后再次curl任意接口，可以获得返回值。以此过程反复。 4.重启服务之后就不再出现这个问题。 想请问下这个问题考虑那些方向出了问题？

初学者小白一枚，本地部署感觉没跑通，大神看看。。 1. 启动的任务，cron 0/1 * * * * ? 是每秒执行一次吧，为啥点进去日志没看到记录呢，日志都是手动执行的，没看到有自动触发的。。。 2. admin项目一直报错 com.mysql.cj.jdbc.exceptions.MySQLTransactionRollbackException: Lock wait timeout exceeded; try restarting transaction
