页面出现乱码，主要时编码格式不对导致的。
1.检查jsp文件中的编码格式是否为"UTF-8"
如果不是，改为"UTF-8"，
2.添加过滤器
package com.yage.myoa.global;
import javax.servlet.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
public class EncodingFilter implements Filter {
private String encoding = "utf-8";
@Override
public void init(FilterConfig filterConfig) throws ServletException {
if(filterConfig.getInitParameter("encoding")!=null){
encoding = filterConfig.getInitParameter("encoding");
}
}
@Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException, IOException {
HttpServletRequest request = (HttpServletRequest)servletRequest;
HttpServletResponse response = (HttpServletResponse)servletResponse;
request.setCharacterEncoding(encoding);
response.setCharacterEncoding(encoding);
filterChain.doFilter(request,response);
}
@Override
public void destroy() {
}
}
在web.xml中添加配置
<filter>
<filter-name>encoding</filter-name>
<filter-class>添加class所在的包</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>utf-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
持续更新
