问题描述
- 用idea15开发 springmvc项目时报404错误,求大神告知原因
-
web.xml配置如下:rest
org.springframework.web.servlet.DispatcherServletcontextConfigLocation
/WEB-INF/rest-servlet.xml1
rest
/restful/*rest-servlet.xml配置如下: <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> <description>Spring MVC for Restful</description> <!--检测注解 --> <context:component-scan base-package="com.onlyyou.java.controller" /> <context:annotation-config /> <mvc:annotation-driven /> <mvc:default-servlet-handler/> </beans> Controller代码如下: @Controller
@RequestMapping("/hello")
public class HelloController {
@RequestMapping(value="/user", method= RequestMethod.GET)
@ResponseBody
public UserBean testParam(@RequestParam("username") String name) {
UserBean userBean = new UserBean();
userBean.setAvatar("123");
userBean.setBirthday("323");
userBean.setCensusRegister("dfda");
return userBean;}
}
最后再浏览器访问http://localhost:6080/onlyyou/restful/hello/user?username=tom报404的错误
解决方案
重新粘贴一下代码,web.xml如下:
<?xml version="1.0" encoding="UTF-8"?>
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
version="3.1">
contextConfigLocation
/WEB-INF/applicationContext.xml
org.springframework.web.context.ContextLoaderListener
<servlet>
<servlet-name>rest</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/rest-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>rest</servlet-name>
<url-pattern>/restful/*</url-pattern>
</servlet-mapping>
解决方案二:
6080端口,,写错了吗?
