j2ee开发中的乱码问题

Question

为了项目出现乱码问题,把mysql安装时的编码和myeclipse中的编码都改成utf-8是不是就能解决了，就不会在出现这种情况了，请高手指点一下

Answer 1

除了这些，还有Jsp页面、资源文件的编码

Answer 2

最好在web.xml配置一个字符的filter。。
<filter>
<filter-name>Encoding</filter-name>
<filter-class>EncodingFilter</filter-class> 
 </filter>
 <filter-mapping>
<filter-name>Encoding</filter-name>
<url-pattern>/*</url-pattern> 
 </filter-mapping>import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;public class EncodingFilter implements Filter {
public void destroy() {
} public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
request.setCharacterEncoding("UTF-8");
chain.doFilter(request, response);
} public void init(FilterConfig filterConfig) throws ServletException {
}
}

Answer 3

还需要像1楼说的这样，把JSP的charset和pageEncoding也改成UTF-8

Answer 4

在 web.xml里面 用编码过滤器过滤一下 比如spring的
<filter>
<filter-name>characterEncodingFilter</filter-name>
<filter-class>
org.springframework.web.filter.CharacterEncodingFilter
</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>utf-8</param-value>
</init-param>
</filter>
