乱码问题解决方法汇总

1. Spring在web.xml中设置过滤器

<filter>
		<filter-name>Set Character Encoding</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>Set Character Encoding</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

2. 在tomcat的server.xml中设置utf-8字符集

<Connector port="8080" 
maxThreads="150" minSpareThreads="25" maxSpareThreads="75" 
enableLookups="false" redirectPort="8443" acceptCount="100" 
debug="0" connectionTimeout="20000" useBodyEncodingForURI="true" 
disableUploadTimeout="true" URIEncoding="UTF-8"/>

3. 在spring-mvc的@ResponseBody出现乱码问题, 解决如下

	<bean id="messageAdapter" 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/html;charset=UTF-8</value>  
                         </list>  
                     </property>  
                 </bean>  
             </list>  
         </property>  
    </bean>
    <mvc:annotation-driven /> 

PS: messageAdapter必须在<mvc:annotation-driven /> 之前!!!!
