初识spring boot maven管理--配置文件

web环境下修改信息需要重启服务器，如果在一个大型的项目中经常重启服务器，那浪费的时间可想而知，今天介绍个好东西 --spring boot！一般学习都是从hello world开始学习的！下面介绍springboot 在maven配置和使用！

先进行pom.xml配置，

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

下载完依赖的jar包下面开始配置spring和springMVC

首先配置和applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 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-2.5.xsd

http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd

http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context-2.5.xsd

http://www.springframework.org/schema/aop

    http://www.springframework.org/schema/aop/spring-aop-3.2.xsd">





<context:annotation-config />

<context:component-scan base-package="com.cml.*">

</context:component-scan>

<bean id="log4jInitialization"

class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">

<property name="targetClass" value="org.springframework.util.Log4jConfigurer" />

<property name="targetMethod" value="initLogging" />

<property name="arguments">

<list>

<value>classpath:log4j.properties</value>

</list>

</property>

</bean>

</beans>

再配置spring mvc：

<context:component-scan base-package="com.cml.controller" />





<mvc:annotation-driven />

<!-- 配置异常处理 <bean id="exceptionHanderResolver" class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver"> 

<property name="exceptionMappings"> <props> <prop key="java.lang.Exception">index</prop> 

</props> </property> </bean> -->





<!-- 设置cookie -->

<bean id="localeResolver"

class="org.springframework.web.servlet.i18n.CookieLocaleResolver">

<property name="cookieName" value="clientlanguage" />

<!-- in seconds. If set to -1, the cookie is not persisted (deleted when 

browser shuts down) -->

<property name="cookieMaxAge" value="100000" />

</bean>

<bean id="multipartResolver"

class="org.springframework.web.multipart.commons.CommonsMultipartResolver">

<!-- 指定所上传文件的总大小不能超过200KB。注意maxUploadSize属性的限制不是针对单个文件，而是所有文件的容量之和 -->

<property name="maxUploadSize" value="200000000" />

<property name="uploadTempDir" value="/temp"></property>

</bean>

<!-- 配置视图解析 -->

<bean

class="org.springframework.web.servlet.view.InternalResourceViewResolver">

<property name="prefix" value="/"></property>

<property name="suffix" value=".jsp"></property>

</bean>

最后需要配置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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"

id="WebApp_ID" version="3.0">

<display-name>MyMVC</display-name>

<welcome-file-list>

<welcome-file>index.jsp</welcome-file>

</welcome-file-list>





<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:applicationContext.xml</param-value>

</context-param>

<context-param>

<param-name>log4jConfigLocation</param-name>

<param-value>classpath:log4j.properties</param-value>

</context-param>







<servlet>

<servlet-name>mvc</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>

<async-supported>true</async-supported>

<load-on-startup>1</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>mvc</servlet-name>

<url-pattern>*.mvc</url-pattern>

</servlet-mapping>

<listener>

<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>

</listener>

<listener>

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>

</web-app>
