JSP页面乱码

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

以及 form表单提交方式为必须为post

修改web.xml，增加编码过滤器，如下（注意，需要设置forceEncoding参数值为true）

<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>

[点我查看freemaker等模版乱码][freemaker]

如果用到了Tomcat的话

在 conf/server.xml 加上 URIEncoding="UTF-8"

返回json乱码

<mvc:annotation-driven>
    		<mvc:message-converters register-defaults="true">
    			<bean
    				class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
    				<property name="supportedMediaTypes">
    					<list>
    						<value>text/html;charset=UTF-8</value>
    						<value>application/json</value>
    					</list>
    				</property>
    				<property name="features">
    					<list>
    						<value>WriteMapNullValue</value>
    						<value>QuoteFieldNames</value>
    						<value>WriteDateUseDateFormat</value>
    					</list>
    				</property>
    			</bean>
    		</mvc:message-converters>
    	</mvc:annotation-driven>

加上<value>text/html;charset=UTF-8</value>

够用了，一般很少出现乱码
