java 乱码解决方法
web.xml 配置
<filter>
<filter-name>MyFilter</filter-name>
<filter-class>com.coCloud.util.MyFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>MyFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
java代码
public class MyFilter implements Filter {
protected String encoding = null;
public void doFilter(ServletRequest request, ServletResponse response,FilterChain chain) throws IOException, ServletException {
System.out.println(encoding);
request.setCharacterEncoding(encoding);
response.setContentType("text/html;charset="+encoding);
chain.doFilter(request, response);
}
@Override
public void init(FilterConfig filterConfig) throws ServletException {
this.encoding = filterConfig.getInitParameter("encoding");
}
@Override
public void destroy() {
}
}
以上还不能解决中文乱码，修提tomcat server.xml配置文件
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" URIEncoding="UTF-8"/>
