jsp提交表单给action出现乱码处理

之前做了个jsp注册用户的，在struts.xml中配置了编码，在web.xml也配置了spring的过滤编码，但是都没有用，后面就写了过滤器，配置在web.xml中就可以了。

EncoderFilter.java

public class EncodeFilter extends StrutsPrepareAndExecuteFilter {
private FilterConfig config = null;
private String encoding = null;

@Override
public void init(FilterConfig config) throws ServletException {
this.config = config;
}

@Override
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
if (encoding == null) {
encoding = config.getInitParameter("encoding");
}
request.setCharacterEncoding(encoding);
response.setCharacterEncoding(encoding);
chain.doFilter(request, response);
}

@Override
public void destroy() {
config = null;
encoding = null;
}
}

web.xml中加入如下配置
<filter>
<filter-name>encodeFilter</filter-name>
<filter-class>com.smc.util.EncodeFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>utf-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encodeFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
