Spring MVC(二)

Spring MVC配置

約束

beans約束:spring必須
context約束:註解和掃描
spring-mvc約束:靜態資源、允許跨域以及攔截器

<?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:mvc="http://www.springframework.org/schema/mvc"
       xmlns:p="http://www.springframework.org/schema/p"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd">
</beans>

掃包

必須配置context約束

<context:component-scan base-package="com.mysite.web" />

前端控制對映器

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" >
    <!--字首-->
    <property name="prefix" value="/WEB-INF/jsp/"/>
    <!--字尾-->
    <property name="suffix" value=".jsp"/>
</bean>

靜態資源放行

如果要使用mvc配置,需要引入mvc約束,以及加一句

<mvc:annotation-driven />

過濾:

<mvc:resources mapping="/editor/**" location="/editor/"/>
<mvc:resources mapping="/bootstrap/**" location="/bootstrap/"/>
<mvc:resources mapping="/imgs/**" location="/imgs/"/>

跨域

<mvc:cors>
    <mvc:mapping path="/**" allowed-origins="*" allowed-methods="*" allowed-headers="*"/>
</mvc:cors>

攔截器

<!--配置攔截器-->
<mvc:interceptors>
    <mvc:interceptor>
        <!--配置攔截器作用的路徑-->
        <mvc:mapping path="/**"/>
        <bean class="com.mysite.interceptor.LoginInterceptor"/>
    </mvc:interceptor>
</mvc:interceptors>
