---中文乱码问题：
1。设置Tomcat config编码 （ok）
2。设置Filter过滤器，配置utf-8编码 （无效???）
3。在AnnotationMethodHandlerAdapter的bean中配置StringHttpMessageConverter （移除掉<mvc:annotation-driven/>才ok）
4。取得response对象，设置编码encode、contentType后返回（ok）
5。<mvc:annotation-driven>内配置StringHttpMessageConverter（ok）
6。前台编码utf-8后再发送数据，后台拿到数据后先解码utf-8

1.配置Tomcat config：
<Connector connectionTimeout="20000" port="8888" protocol="HTTP/1.1" redirectPort="8443" URIEncoding="UTF-8"/>  

2.web.xml
（no???）

	<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>
		<init-param>
			<param-name>forceEncoding</param-name>
			<param-value>true</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>CharacterEncodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping> 

3.springmvc转换器

注意：这样配置的时候要移除掉默认的<mvc:annotation-driven>，不然会不起作用（why??），另外配置上<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />等等。

	<!--启动Spring MVC的注解功能,设置编码方式，防止乱码 -->
	<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
		<property name="messageConverters">
			<list>
				<bean class="org.springframework.http.converter.StringHttpMessageConverter">
					<property name="supportedMediaTypes">
						<list>
							<value>text/plain;charset=UTF-8</value>
						</list>
					</property>
				</bean>
			</list>
		</property>
	</bean> 

4.response

			try {
				response.setCharacterEncoding("utf-8");
				response.setContentType("text/html;charset=UTF-8");
				OutputStream out = response.getOutputStream();
				PrintWriter pw = new PrintWriter(new OutputStreamWriter(out,"utf-8"));
				pw.println(result);
				pw.flush();
				pw.close();
			} catch (Exception e) {
				e.printStackTrace();
			}

5、<mvc:annotation-driven>

<pre class="html" name="code">	<!-- 简化springmvc的相关配置 -->
	<mvc:annotation-driven>
		<!-- 解决utf-8页面乱码问题 -->
		<mvc:message-converters register-defaults="true">
			<bean class="org.springframework.http.converter.StringHttpMessageConverter">
				<!-- <property name="supportedMediaTypes" value="text/pain;charset=UTF-8" /> -->
				<property name="supportedMediaTypes">
						<list>
							<value>text/plain;charset=UTF-8</value>
							<value>text/html;charset=UTF-8</value>
							<value>application/json;charset=UTF-8</value>
						</list>
				</property>
			</bean>
		</mvc:message-converters>
	</mvc:annotation-driven>

6。前台编码utf-8后再发送数据，后台拿到数据后先解码utf-8
