SpringMVC请求乱码问题
今天做一个项目实现插入数据的功能,最开始没有添加FilterEncoding处理字符集乱码了,那是正常的,后来我添加过之后依然还是乱码,让我
百思不得其解,代码配置如下:
EncodingFilter .java
public class EncodingFilter implements Filter { private String encode = null; @Override public void destroy() { // TODO Auto-generated method stub encode = null; } @Override public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { if(null == request.getCharacterEncoding()){ request.setCharacterEncoding(encode); } chain.doFilter(request, response); } @Override public void init(FilterConfig filterConfig) throws ServletException { String encode = filterConfig.getInitParameter("encoding"); if(this.encode == null){ this.encode = encode; } } }
web.xml 配置
<filter> <filter-name>EncodingFilter</filter-name> <filter-class>com.smy.util.EncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>EncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
我反复检查了好几遍,包括(项目编码,jsp页面编码。。。),没发现问题啊,最后无奈又把 Tomcat 编码检查了一下,发现 Tomcat 少了字符集设置,
Tomcat默认字符集是 ISO-8859-1 ,于是添加这一句:
<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" URIEncoding="UTF-8" />
就这样,乱码问题就解决了。。
