解决中文乱码，在web.xml中配置核心过滤器

方法一、手动编写中文乱码过滤器

public void doFilter(ServletRequest request, ServletResponse response, 
FilterChain chain) throws IOException, ServletException { 
request.setCharacterEncoding("UTF-8"); 
response.setCharacterEncoding("UTF-8"); 
chain.doFilter(request,response); 
System.out.println("过滤器utf-8"); 
} 

 
 
characterEncoding 
dlr.co.util.CharacterEncodingFilter 
 
 
characterEncoding 
/* 
 

方法二、使用核心过滤器

 
 
SetCharacterEncoding 
 
org.springframework.web.filter.CharacterEncodingFilter 
 
encoding 
UTF-8 
 
 
forceEncoding 
true 
 
 
 
SetCharacterEncoding 
/* 
  REQUEST  
  FORWARD  
  INCLUDE 
     
   
  SetCharacterEncoding 
  *.jsp
