在用intelijIDEA的时候,因为是第一次接触这个,对项目的发布很是迷糊。怎么弄老是404错误:
Type Status Report
Message/****
Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.
无奈之下,换成eclipse,发现问题也是存在。捣鼓了好几天,都不知道问题出在哪里。后来打算新建一个Web项目,新建一个index.jsp正确运行后再慢慢复制以前的项目文件到该正确web下面,看看问题出在哪里。后来终于发现了,使用新建的web项目下的默认web.xml文件时,项目正确运行:
web.xml自动生成的默认配置如下:
<?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"> <display-name>WebProject</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> </web-app>
我原来的报错项目web.xml配置如下:
<?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_2_5.xsd" version="2.5"> <filter> <filter-name>spring filter</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> </filter> <filter-mapping> <filter-name>spring filter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <servlet> <servlet-name>ServletProxyService</servlet-name> <servlet-class>com.proxy.ServletProxyService</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>ServletProxyService</servlet-name> <url-pattern>/ServletProxyService</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <error-page> <error-code>404</error-code> <location>/error.html</location> </error-page> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/classes/applicationContext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> </web-app>
使用这个web.xml项目就无法运行:
web.xml换成自动生成的就可以运行了。具体原报错项目web.xml哪里错了,应该是springmvc相关配置出错吧!
就在刚刚:2018-7-29 12点18分
我把web.xml最后几段删除:
<listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>
发现项目正确运行,所以就是这个spring的配置有问题。

这个链接完美解决了我的问题:
就是将注释里的代码改为这个:
<!-- <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/applicationContext.xml</param-value> </context-param> --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/applicationContext-*.xml,classpath*:applicationContext-*.xml</param-value> </context-param>
