SSM中引入layui失败，springmvc.xml配置访问静态资源
作者：互联网
springmvc访问静态资源的springmvc.xml配置
一. 问题及需求
由于Spring MVC的web.xml文件中关于DispatcherServlet拦截url的配置为"/"，拦截了所有的请求，同时*.js，*.jpg等静态资源也被拦截了，导致运行时跳转后的页面无法加载layUI资源，如下图所示。
web.xml：
<!-- 配置DispatcherServlet所要拦截的url -->
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
index.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>在线测试</title>
<meta name="renderer" content="webkit">
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- 注意：项目正式环境请引用本地地址 -->
<link rel="stylesheet" href="layui/css/layui.css">
<script src="layui/layui.js"></script>
</head>
<body>
<!-- 你的 HTML 代码 -->
<script>
layui.use(['layer', 'form'], function(){
var layer = layui.layer;
var form = layui.form;
<!--弹出窗口Hello World-->
layer.msg('Hello World');
});
</script>
</body>
</html>
需求：正常加载出layUI资源。
二. 解决方案
问题出在：只需要修改springmvc.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
https://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/mvc
https://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!--注解固定写法-->
<!--自动扫描包：让指定包下的注解生效，有IOC容器统一管理-->
<context:component-scan base-package="com.tongda.controller"/>
<!--SpringMvc 不处理静态资源，视图解析器不进行过滤，如 .css .js .html-->
<mvc:default-servlet-handler/>
<!--
支持mvc注解驱动
在Spring中一般采用@RequestMapping注解来完成映射关系
要想是@RequestMapping注解生效
必须向上下文中注册DefaultAnnotationHandlerMapping
和一个AnnotationMethodHandlerAdapter实例
这两个实例分别在类级别和方法级别处理
而annotation-driven配置帮助我们自动完成上述两个实例的注入
-->
<!--//<mvc:annotation-driven/>-->
<!--json乱码配置问题，如果报了500错，就去掉这行中文注释-->
<mvc:annotation-driven>
<mvc:message-converters register-defaults="true">
<bean class="org.springframework.http.converter.StringHttpMessageConverter">
<constructor-arg value="UTF-8"/>
</bean>
<bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
<property name="objectMapper">
<bean class="org.springframework.http.converter.json.Jackson2ObjectMapperFactoryBean">
<property name="failOnEmptyBeans" value="false"/>
</bean>
</property>
</bean>
</mvc:message-converters>
</mvc:annotation-driven>
<!--以上的是定死的代码，
以下是配置视图解析器，prefix前缀，suffix后缀-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" id="internalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
<!--过滤静态资源:导入layui时-->
<mvc:resources mapping="/layui/**" location="WEB-INF/layui/"/>
</beans>
三. 测试
3.1. 在WEB-INF下创建名为layui的文件夹，最后项目结构如下图：
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>在线测试</title>
<meta name="renderer" content="webkit">
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- 注意：项目正式环境请引用本地地址 -->
<link rel="stylesheet" href="layui/css/layui.css">
<script src="layui/layui.js"></script>
</head>
<body>
<table class="layui-hide" id="test"></table>
<!-- 注意：项目正式环境请引用该地址 -->
