开发步骤

基本配置：

在webxml中配置spring的监听器 springMvc的前端控制器

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xsi:schemaLocation="
         http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd
"
         version="4.0">

    <!--全局初始化参数-->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>

    <!--spring的监听器-->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!--配置spring的前端控制器  springmvc-->
    <servlet>
        <servlet-name>DispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!--初始化参数-->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring-mvc.xml</param-value>
        </init-param>
        <!--在服务器开启时开启-->
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <!--表示给谁加上这个-->
        <servlet-name>DispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

在Spring-mvc.Xlm中配置基本参数：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       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.xsd
       http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
">
    <!--驱动加载-->
    <mvc:annotation-driven/>
    <!--视图配置 就是在跳转的时候可以省略前后缀-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/pages/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

    <!--开房静态资源访问-->
    <mvc:default-servlet-handler/>

    <!--开启注解扫描-->
    <context:component-scan base-package="com.xzh"/>
</beans>

applicationContext.xml(spring配置文件)中配置基本文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       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.xsd
       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
">
    <!--引入配置文件-->
    <context:property-placeholder location="classpath:jdbc.properties"/>

    <!--配置dataSource-->
    <bean class="com.alibaba.druid.pool.DruidDataSource" id="dataSource">
        <property name="username" value="${jdbc.username}"/>
        <property name="url" value="${jdbc.url}"/>
        <property name="password" value="${jdbc.password}"/>
        <property name="driverClassName" value="${jdbc.driver}"/>
    </bean>

    <!--配置JdbcTemplate（spring的事务管理东西）-->
    <bean class="org.springframework.jdbc.core.JdbcTemplate" id="jdbcTemplate">
        <property name="dataSource" ref="dataSource"/>
    </bean>

    <!--开启注解扫描-->
    <context:component-scan base-package="com.xzh"/>

</beans>

使用mvc跳转到某个函数方法：

@RequestMapping("/save")
public String save(Role role){
    roleService.save(role);
//下面这一句话
    return "redirect:/role/list";
}

解决网页传过来的中文乱码问题：

在webxml中配置如下东西：

<!--解决乱码过滤器-->
<filter>
    <filter-name>CharacterEncodingFilter</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>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
