Spring MVC 总结一(spring mvc 基本例子)

一、目录结构

　　

二、 具体步骤

　　2.1 applicationContext.xml 配置

<?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"
       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-3.0.xsd">

       <context:annotation-config />
</beans>

　　2.2 mvc.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-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">

       <mvc:annotation-driven/>
       <!-- 自动扫描包 -->
       <context:component-scan base-package="pr.cgl.controller" />

       <!-- mvc返回页面的配置 -->
       <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
              <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
              <!-- 模板路径为WEB-INF/pages/ -->
              <property name="prefix" value="/WEB-INF/"/>
              <!-- 视图模板后缀为.JSP -->
              <property name="suffix" value=".jsp"/>
       </bean>

</beans>

　　2.3 web.xml

<?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">


    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
    <context-param>
        <param-name>webAppRootKey</param-name>
        <param-value>SpringWebT1.root</param-value>
    </context-param>
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            classpath:applicationContext.xml
        </param-value>
    </context-param>

    <!-- 启动spring 加载 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

   <context-param>
        <param-name>log4jConfigLocation</param-name>
        <param-value>classpath:log4j.properties</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
    </listener>

    <!-- 加载springmvc -->
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:mvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <!-- 以.htm结尾的都被mvc拦截 -->
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/SpringWebT1/*</url-pattern>
    </servlet-mapping>

</web-app>

　　2.4 添加日志

　　　　2.4.1 配置log4j.properties

### Log4j Properties ###

# Options are <DEBUG, INFO, WARN, ERROR or FATAL>

# Use two appenders, one to log to console, another to log to a file
log4j.rootLogger=ALL,debug,info,error,console
#log4j.rootLogger=debug,error,console
#log4j.rootLogger=error,console
log4j.threshold=ALL

log4j.category.com.jlt.mis=debug,AdapterFile
log4j.appender.AdapterFile=org.apache.log4j.RollingFileAppender
log4j.appender.AdapterFile.MaxFileSize=46MB
log4j.appender.AdapterFile.MaxBackupIndex=3
log4j.appender.AdapterFile.File=${SpringWebT1.root}/logs/JLTShop.log
log4j.appender.AdapterFile.append=true
log4j.appender.AdapterFile.layout=org.apache.log4j.PatternLayout
log4j.appender.AdapterFile.layout.ConversionPattern=%t  %d{DATE} %c{3} %p - %m%n

# WRITE LOG TO A CONSOLE
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.Target=System.out
log4j.appender.console.layout=org.apache.log4j.PatternLayout
#log4j.appender.console.layout.ConversionPattern=[SpringWebT1] %d{MM/dd/yyyy HH:mm:ss,SSS} - %C{1}.%M (%F:%L) >> %p: %m%n
log4j.appender.console.layout.ConversionPattern=%d{MM HH:mm:ss,SSS} - %M (%F:%L) >> %p: %m%n
log4j.appender.console.threshold=DEBUG

# WRITE LOG TO A FILE, ROLL THE FILE EVERY DAY
log4j.appender.info=org.apache.log4j.DailyRollingFileAppender
log4j.appender.info.layout=org.apache.log4j.PatternLayout
log4j.appender.info.layout.ConversionPattern=%d{MM/dd/yyyy HH:mm:ss,SSS}-%C{1}.%M (%F:%L) >> %p: %m%n
log4j.appender.info.DatePattern='.'yyyy-MM-dd
log4j.appender.info.threshold=INFO
log4j.appender.info.append=true
log4j.appender.info.File=${SpringWebT1.root}/logs/infoLogFile.log

log4j.appender.debug=org.apache.log4j.DailyRollingFileAppender
log4j.appender.debug.layout=org.apache.log4j.PatternLayout
log4j.appender.debug.layout.ConversionPattern=%d{MM/dd/yyyy HH:mm:ss,SSS} - %C{1}.%M (%F:%L) >> %p: %m%n
log4j.appender.debug.DatePattern='.'yyyy-MM-dd
log4j.appender.debug.threshold=DEBUG
log4j.appender.debug.append=true
log4j.appender.debug.File=${SpringWebT1.root}/logs/debugLogFile.log

log4j.appender.error=org.apache.log4j.DailyRollingFileAppender
log4j.appender.error.layout=org.apache.log4j.PatternLayout
log4j.appender.error.layout.ConversionPattern=%d{MM/dd/yyyy HH:mm:ss,SSS} - %C{1}.%M (%F:%L) >> %p: %m%n
log4j.appender.error.DatePattern='.'yyyy-MM-dd
log4j.appender.error.threshold=ERROR
log4j.appender.error.append=true
log4j.appender.error.File=${SpringWebT1.root}/logs/errorLogFile.log
2.4.2 配置web.xml
　　添加以下代码段

    <context-param>
        <param-name>log4jConfigLocation</param-name>
        <param-value>classpath:log4j.properties</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
    </listener>

　　2.5 controller

package pr.cgl.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 * Created by CGL on 2015/9/10.
 */
@Controller
@RequestMapping("/main")
public class TestController {

    @RequestMapping("/index.html")
    public String index(Model m){
        m.addAttribute("name", "clg");
        return "index";
    }
}
2.6 测试
　　地址栏输入http://localhost:8080/SpringWebT1/main/index.html，得到Hello, clg
