struts2 jsp提交到action出现中文乱码问题

a.首先在struts.xml中加固定值（和jsp页面的编码要一致）

<constantname="struts.i18n.encoding"value="UTF-8"></constant>

b.若不行，再写一个filter过滤器，处理中文字符编码转换问题：

packagefilters;

importjava.io.IOException;

importjavax.servlet.Filter;

importjavax.servlet.FilterChain;

importjavax.servlet.FilterConfig;

importjavax.servlet.ServletException;

importjavax.servlet.ServletRequest;

importjavax.servlet.ServletResponse;

public classTomcatFilter implements Filter {

public void destroy()

{ }

public void doFilter(ServletRequest req,ServletResponse res,

FilterChain chain) throws IOException,ServletException {

req.setCharacterEncoding("UTF-8");

chain.doFilter(req, res);

}

public void init(FilterConfig arg0) throwsServletException { }

public boolean accept(Object arg0) throwsIOException {

// TODO Auto-generated method stub

return false;

}

}

注：实现Filter接口，要引入importjavax.servlet.Filter这个包，否则会报错。



然后，在web.xml中进行配置，记住要配在<filter-name>struts2</filter-name>之前。

<filter>

<display-name>TomcatFilter</display-name>

<filter-name>TomcatFilter</filter-name>

<filter-class>filters.TomcatFilter</filter-class>

</filter>

<filter-mapping>

c.要保证数据库的编码与刚才的编码都一致
