Client requests garbled

The principle is to create a filter to filter all requests to see encoding each request is the specified encoding
implementation code:

1. Create a filter to solve the garbage

   package com.imooc.oa.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";
   	public void init(FilterConfig filterConfig) throws ServletException {
       	if(filterConfig.getInitParameter("encoding")!=null){
           	encoding = filterConfig.getInitParameter("encoding");
       	}
   	}
   
   	public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
       	HttpServletRequest request = (HttpServletRequest)servletRequest;
       	HttpServletResponse response = (HttpServletResponse)servletResponse;
       	request.setCharacterEncoding(encoding);
       	response.setCharacterEncoding(encoding);
       	filterChain.doFilter(request,response);
   	}
   
   	public void destroy() {
   	}
   }
   
   

2. The filter configuration in web.xml

   <!--处理中文乱码-->
   <filter>
   	<filter-name>encodingFilter</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>
   	<init-param>
     		<param-name>forceEncoding</param-name>
     		<param-value>true</param-value>
   	</init-param>
   </filter>
   <filter-mapping>
   	<filter-name>encodingFilter</filter-name>
   	<url-pattern>/*</url-pattern>
   </filter-mapping>
   

Static Resource Access

Solving principle: Configuring static resources in defaultservlet spring provides us access

<!--设置访问静态资源-->
<servlet-mapping>
  <servlet-name>default</servlet-name>
  <url-pattern>*.css</url-pattern>
</servlet-mapping>
<servlet-mapping>
  <servlet-name>default</servlet-name>
  <url-pattern>*.js</url-pattern>
</servlet-mapping>
<servlet-mapping>
  <servlet-name>default</servlet-name>
  <url-pattern>*.jpg</url-pattern>
</servlet-mapping>
