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>
如果用到了Tomcat的话
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" URIEncoding="UTF-8"/>
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
