SpringMVC遇到的坑
1、SpringMVC配置文件
复制代码
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:context="http://www.springframework.org/schema/context"

<context:component-scan base-package="com.test.controller"/>
<!-- 静态资源放行 -->
<mvc:resources location="/static/" mapping="/static/**"/>
<!-- Spring 3.0.x中使用了mvc:annotation-driven后，默认会帮我们注册默认处理请求，参数和返回值的类 -->
<!-- 设置了静态资源放行后不加该代码请求下不来 -->
<mvc:annotation-driven/>
<!-- jsp响应路径 -->
<bean id="viewResolverJsp"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/" />
<property name="suffix" value=".jsp" />
<property name="order" value="1"/>
</bean>
</beans>

2、web.xml文件
复制代码
<?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">

3、项目结构
创建一个war类型的maven工程
▲MSI
websocket
D src/main/java
D src/main/resources
src/test/java
src/test/resources
D目JRE System Library [JavaSE-1.8]
D目Maven Dependencies
D目Apache Tomcat v8.5 [Apache Tomcat v8..
src
▲当main
A上webapp
上jsp
D上static
...............
1 2 WEBINF
..........
O web.xml
用index.jsp
test
D二target
日pom.xml
注：jsp页面最好放在WEB-INF同级目录，别问为什么，页面找了好久都没找到，就算配置了也没找到，有用没用吧<mvc:annotation-driven/>加上，避免请求下不来，静态资源找不到
