有时候使用SpringMVC框架提交表单时会出现中文乱码，以下是我亲自试验过的配置字符过滤器的两种：
1、在web.xml中配置
<filter>
<filter-name>characterEncodingFilter</filter-name>
<filter-class>orgspringframeworkwebfilterCharacterEncodingFilter</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>
2、JavaConfig
import javax.servlet.Filter; import org.springframework.web.filter.CharacterEncodingFilter;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer; public class JavaSpringIn extends AbstractAnnotationConfigDispatcherServletInitializer { //配置字符过滤器
@Override
protected Filter[] getServletFilters() {
CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
characterEncodingFilter.setEncoding("UTF-8");
characterEncodingFilter.setForceEncoding(true);
return new Filter[] {characterEncodingFilter};
} }
