Spring是一个开源框架，Spring是于2003 年兴起的一个轻量级的Java 开发框架，由Rod Johnson 在其著作Expert One-On-One J2EE Development and Design中阐述的部分理念和原型衍生而来。它是为了解决企业应用开发的复杂性而创建的。框架的主要优势之一就是其分层架构，分层架构允许使用者选择使用哪一个组件，同时为 J2EE 应用程序开发提供集成的框架。Spring使用基本的JavaBean来完成以前只可能由EJB完成的事情。然而，Spring的用途不仅限于服务器端的开发。从简单性、可测试性和松耦合的角度而言，任何Java应用都可以从Spring中受益。Spring的核心是控制反转（IoC）和面向切面（AOP）。简单来说，Spring是一个分层的JavaSE/EEfull-stack(一站式) 轻量级开源框架。

官方语言结束。

spring的搭建，网上文章一大堆，我就不做重复运动了。这里讲下步骤，不明白的可以百度下。对了，说下环境，jdk64位，apache-tomcat-7.0.61-64位，Eclipse 64位。项目是spring4+，springmvc4+，mybatis3.2+，mysql5+64位，maven。好了，开始pom配置，至于项目创建，以后会专门有个博客记录。

好像springmvc也一块弄好了，干脆把springmvc的配置也贴上吧

spring-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:p="http://www.springframework.org/schema/p"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xsi:schemaLocation="

http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
http://www.springframework.org/schema/mvc 
http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"
	default-lazy-init="true">
	<!--使Spring支持自动检测组件，如注解的Controller -->
	<context:component-scan base-package="com.cmicroentropy.soa.controller" />

	<bean id="viewResolver"
		class="org.springframework.web.servlet.view.InternalResourceViewResolver"
		p:prefix="/WEB-INF/jsp/" p:suffix=".jsp" />
	<bean id="mappingJacksonHttpMessageConverter"
		class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
		<property name="supportedMediaTypes">
			<list>
				<value>application/json;charset=UTF-8</value>
			</list>
		</property>
	</bean>
	<bean
		class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />
	<bean
		class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
		<property name="messageConverters">
			<list>
				<bean id="utf8StringHttpMessageConverter"
					class="com.cmicroentropy.soa.util.converter.UTF8StringHttpMessageConverter" />
					<ref bean="mappingJacksonHttpMessageConverter" />
			</list>
		</property>
	</bean>
	<!-- SpringMVC上传文件时，需要配置MultipartResolver处理器 -->
	<bean id="multipartResolver"
		class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
		<property name="defaultEncoding" value="UTF-8" />
		<!-- 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="5000000" />
	</bean>
	<!-- SpringMVC在超出上传文件限制时，会抛出org.springframework.web.multipart.MaxUploadSizeExceededException -->
	<!-- 该异常是SpringMVC在检查上传的文件信息时抛出来的，而且此时还没有进入到Controller方法中 <bean id="exceptionResolver" 
		class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver"> 
		<property name="exceptionMappings"> <props> -->
	<!-- 遇到MaxUploadSizeExceededException异常时，自动跳转到/WEB-INF/jsp/error_fileupload.jsp页面 
		<prop key="org.springframework.web.multipart.MaxUploadSizeExceededException">error_fileupload</prop> 
		</props> </property> </bean> -->
	<!-- 启动 Spring MVC 的注解功能，完成请求和注解 POJO 的映射 -->
	<context:annotation-config />
</beans>

这里有个字符编码转换的，下面是代码：

package com.cmicroentropy.soa.util.converter;

import java.io.IOException;
import java.io.OutputStreamWriter;
import java.nio.charset.Charset;
import java.util.Arrays;
import java.util.List;

import org.springframework.http.HttpOutputMessage;
import org.springframework.http.MediaType;
import org.springframework.http.converter.StringHttpMessageConverter;
import org.springframework.util.FileCopyUtils;

public class UTF8StringHttpMessageConverter extends StringHttpMessageConverter {
	private static final MediaType utf8 = new MediaType("text", "plain", Charset.forName("UTF-8"));
	private boolean writeAcceptCharset = true;
	@Override
	protected MediaType getDefaultContentType(String dumy) {
		return utf8;
	}

	protected List<Charset> getAcceptedCharsets() {
		return Arrays.asList(utf8.getCharSet());
	}

	protected void writeInternal(String s, HttpOutputMessage outputMessage)	throws IOException {
		if (this.writeAcceptCharset) {
			outputMessage.getHeaders().setAcceptCharset(getAcceptedCharsets());
		}
		Charset charset = utf8.getCharSet();
		FileCopyUtils.copy(s, new OutputStreamWriter(outputMessage.getBody(), charset));
	}

	public boolean isWriteAcceptCharset() {
		return writeAcceptCharset;
	}

	public void setWriteAcceptCharset(boolean writeAcceptCharset) {
		this.writeAcceptCharset = writeAcceptCharset;
	}

}

到此为止。
