表单post提交中文乱码

在web.xml中添加过滤器，sPRing3.x以后有自带过滤器，配置就好<filter> <filter-name>SpringEncodingFilter</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>SpringEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>配置过滤器要注意位置要把编码放到spring mvc的servelet配置的前面

<xsd:element name="filter"                type="javaee:filterType"/>   <xsd:element name="filter-mapping"                type="javaee:filter-mappingType"/>   <xsd:element name="listener"                type="javaee:listenerType"/>   <xsd:element name="servlet"                type="javaee:servletType"/>   <xsd:element name="servlet-mapping"                type="javaee:servlet-mappingType"/>   <xsd:element name="session-config"                type="javaee:session-configType"/>   <xsd:element name="mime-mapping"                type="javaee:mime-mappingType"/>   <xsd:element name="welcome-file-list"                type="javaee:welcome-file-listType"/>   <xsd:element name="error-page"                type="javaee:error-pageType"/>   <xsd:element name="jsp-config"                type="javaee:jsp-configType"/>   <xsd:element name="security-constraint"                type="javaee:security-constraintType"/>   <xsd:element name="login-config"                type="javaee:login-configType"/>   <xsd:element name="security-role"                type="javaee:security-roleType"/>   <xsd:group ref="javaee:jndiEnvironmentRefsGroup"/>   <xsd:element name="message-destination"                type="javaee:message-destinationType"/>   <xsd:element name="locale-encoding-mapping-list"                type="javaee:locale-encoding-mapping-listType"/>

还可以在页面表单中加accept-charset标签<form action="/testMethodPost" method="POST" accept-charset="utf-8"
